Baked Sweet Potato Chips

A few weeks ago we had our neighbors up for dinner and they brought the most fabulous sweet potato chips; baked sweet potato chips, I might add. I’d never tasted sweet potato chips so crispy, light and flavorful! Two bites in and I knew I needed the recipe. Thanks Laura, you’re a lifesaver. John finally likes sweet potatoes in some form. This is some kind of pre-Christmas miracle.

Out of curiosity since I don’t have a mandolin, I made these sweet potato chips two ways: I sliced half the batch thinly with a knife (left) and the other half with a vegetable peeler (right). The results were equally delicious, but I must say the knife method yielded a more satisfying bite so I’d recommend this over the peeler.

These chips are awesome! So crispy and flavorful, and all they require is a little olive oil and a pinch of salt before going into the oven to bake for a couple hours. That’s the trick – keeping your oven at 250 degrees and flipping once during the baking process to make sure they crisp up on both sides. The result is amazing.

These are a great stand-alone side dish but you could also top them with black beans, salsa and cheese for some crazy delicious nachos. Or you could add them to a sandwich for some serious crunch. Dream big people, the possibilities are endless.

Baked sweet potato chips that are incredibly flavorful and crispy. Perfect alongside sandwiches, burgers, chili and the like.
Recipe type: Side Dish
Cuisine: Vegetarian
  • 2 organic sweet potatoes
  • 2 Tbsp olive oil
  • 1/4 tsp sea salt (optional)
  1. Preheat oven to 250 degrees F and position oven rack in the center of the oven.
  2. Rinse and dry your sweet potatoes thoroughly and slice them as uniformly thin as possible. If you have a mandolin, use it. Otherwise, use a very sharp knife to get these uniformly thin. Know that chips that are too thick in parts won't crisp up all the way. Still delicious, just not "chip" crispiness.
  3. Toss slices in a touch of olive oil to lightly coat, then sprinkle with salt. Lay out in a single layer on a baking sheet and bake for about 2 hours, flipping chips once at halfway point to ensure even cooking. I also rotated mine for more even cooking (optional but recommended).
  4. Remove once crisp and golden brown. Some may feel a little tender in the middle but take them out and let them rest for 10 minutes or so to crisp up before sampling. Serve immediately.
*Note: Know that chips that are too thick in some spots may not crisp up all the way. They're still delicious, just not as crispy as the uniformly thin chips. It takes practice!
*I recommend organic sweet potatoes for taste and health reasons, since you don't peel off the skin where pesticides can reside.

* RECIPE UPDATED 1/26/14: I originally had the temperature at 200 degrees, but a few readers had trouble with the chips not crisping up properly. So I have retested with success, adjusting the temperature to 250 degrees. It still takes about 2 hours, but the low temperature allows them to get more evenly crispy.

    Wow….I cut them differently, but, I make them as treats for my Service Dog…..he loves them…..But, much the same, cut them into chunks, no oil or salt, oven is just at 250…..same time,

    Why Not for ME???

  2. alex says

    wow these did not turn out well at all for me. i followed the recipe exactly, but then half way through i noticed they were all getting dark rather quickly. i flipped them and moved the pans around in the oven and left them for the rest of the time and then when i took them out most of them were either burnt or undercooked and soggy. i’m not sure why they didn’t work out for me, i so badly want them to be delicious! maybe i will try them again with a different temperature/time.

    • Dana says

      Karri! I just consulted with my friend whom I borrowed this recipe from and she thinks she had her oven on 200 instead of 300. Sorry for any confusion! I’ve changed that in the original recipe. I still think you could bake them at 300 degrees, but just be sure to check them at the 25, 30 and 35 minute mark so they don’t burn. Hope that helps!

  3. Lee Ann says

    I love sweet potatoes, but I struggle with peeling and cutting them. They are so thick and hard! Is there an easier way to do it?

    • Dana says

      Lee Anne, just try and buy smaller potatoes – they’re much more tender : ) AND use a super sharp knife! That should help.

    • Renita says

      Don’t peel them. Cut them into circles. The skin is delicious! Bake some kale on the side as well you will see healthy and delicious.

  4. says

    I bought a microwave chip maker and I just cannot get the hang of it – they turn out soggy all the time. I think I’ll just have to bake them like this instead!

    • Leslie says

      Oh sweet Charlotte! Please look into the dangers of microwave ovens and what they do to the structure of the food; you might find the answer to your dilemma. So happy you are baking the chips instead!

    • D'Ann Martin says

      Same with me Charlotte! I paid through the nose for a chip maker from pampered chef, and despite all my efforts to make healthy chips for my kids, it turns out awful each batch:( Anxious to try this recipe! Good luck to you!

  5. Tatiana says

    I made these chips, also at 300, but I only needed to bake mine for about 20 mins before they were perfectly chipped. I don’t think it would be a circulation problem as you suggested for the other person….I just don’t understand how one would bake these for 2 hours?

  6. MarieR says

    I used a food processor to slice the potatoes super thin; backed them at 200 degrees F for 2 hours – perfect. Curly; no burnt slices, and I never had to turn them. I just set it and forget it (after putting the timer on). Puuuuurfect!

  7. Ingrid says

    Trying right now! I used the slicing blade on the Cuisinart and tossed/massaged olive oil and Cajun seasoning into the slices with my hands in a big bowl. Can’t wait for them to finish baking.

  8. Ingrid says

    The outcome? I really liked adding spicy Cajun seasoning I used. The oven temp of 200 is far too slow for the density of this vegetable. They need to be baked not dehydrated. I upped it to 350 degrees to get baked and crisper. They were still chewy but I liked the texture. Had them with fresh cucumber yogurt dip. Next time I will toss them in beaten egg whites with Cajun seasoning and bake @ 350 to cook thru and then lower heat to crisp.

  9. Mysctyx says

    Hey I am about to try these but I have noticed a little confusion on your page. When you are scrolling down in between the pictures, you had written to keep your oven at 300 degrees. Then on the actual recipe it said 200 degrees. Could that be why a few people have gotten very different results?

  10. says

    I tried your recipe this morning. I sliced the potatoes on a mandolin, so they were thin and even, yet after two hours at 200° they were still leathery and not crisp at all. I left them in an extra half hour and they are still only leathery. The only thing I can think that might change the temperature and timing is………did you use a convection oven?

  11. pete says

    something is amiss. at 200 degrees it would take longer than 1.5-2 hours. i tried this and after 1 hour the slices were no where close to even part way done. and they were thinner than 1/8 inch. if you think about it using a dehydrator at 180 degrees it takes most of the day to process something.

  12. C says

    I followed instructions to a T and 4 hours later and these aren’t crispy! I’ve tried everything, I’m going to take the second prepared batch and just mash them, so disappointed, sweet potato chips are my fave.

  13. Val says

    I wish I had read all the comments before starting these! AND a big factor was going by the pic (finally – I saw CRISPY and not burned chips) Disappointed to see in the comments that most people still are having the burned or soggy problem (that I have seen myself with several past tries).

    WELP – nothing else to do but keep going. They are going in NOW at 200 degrees for 1.5 hours.. maybe 2. After this … I’m done. I will admit defeat and never make a sweet potato chip again. (please use recipes you’ve tried … and picture from the actual recipe. – thanks)

  14. jodi2672 says

    I’ve tried these 3 times now from 350 250 200 with same results,I also bought a mandolin thinking it would help..but no I get leathery, some uncooked, nasty chip..could it be not enough oil?? I’m really wanting to make these and come out right!!

  15. Bill Legg says

    Have any of you tried this recipe with a food dehydrator? I have one that goes up to 200degrees and thought it might work without the fear of burning. If it does or doesn’t work maybe I’ll try it and post the results. Happy cooking all.

  16. violet hoffman says

    It seems to me that cutting the sweet potatoes crosswise would make them cook much more quickly than cutting them lengthwise.
    Haven’t tried yet but will do so today.

  17. Nicole says

    Just tried this recipe…huge bummer. I sliced up a ~2 inch diameter sweet potato by hand (get thicker potatoes, they’ll shrivel up when baking) about 2 mm thick, tossed with olive oil and salt, and baked them for about 2 hours at 250 degrees F. I flipped them twice during baking. I got so excited because when I pulled the chips out, they looked like they’d be so crispy and delicious…but they were leathery…but still delicious, just ridiculously hard to eat. Weirdly, some of the thinner slices turned out perfect.

    Unlike in the other comments, I really think a mandolin would come in handy.

    • says

      Nicole, thanks for sharing your experience with this recipe. I have only made it once myself and they turned out really well! But since other commenters have had some issues, I’m going to give these another go to pinpoint the ideal temperature, cook time and method. Thanks!

      • DT says

        Type of baking sheet matters. Dark vs light. I think that a dark baking sheet will produce crisper. Also if you have a baking sheet with a rack like restaurants use for bacon you might get optimal results. I have had good luck with the vegetable peeler at a shorter bake time. If you have uneven oil distribution the slices soaking up more oil will be leathery folks.

  18. Kimbertangleknot says

    I think a mandolin or some other type of thing to slice them thinner would work better. I too tried cutting the sweet potato with a knife, and it took almost 6 hours to properly dry them out in the oven at 200°. However the thinner ones were done much sooner. While I’m all for using less tools to accomplish, I think something other than a “peeler” or knife would make this work better. I’ll try it again using a mandolin, because this is the only way I like sweet potatoes really. Other than that, they were good, but the ones that had a shorter cook time turned out much better and tastier.

    • kimbertangleknot says

      I retried this recipe today, and found that using my food processor that has the slicing attachment helped (I also got a lot more disks). I preheated the oven to 350, and then lowered it to 250. I didn’t put them on parchment (next time I will try that). I find that in my electric oven, between 275 and 300 works out better. I only have a few that are soggy and that’s more due to me being lazy and not making sure they were spread out nicely. I used a white sweet potato this time, and while it started to turn brown because I didn’t throw them in water right away, they still taste really good. I love eating them with some sour cream based dip. It’s a great combo.

  19. Laura A says

    Can the author of this tell us if it is degrees Celsius or Fahrenheit? I have been baking them at 500 degrees F and still getting soggy stuff. Thanks

  20. Ben says

    Regarding preferring organic due to the pesticides on the skin, I would have thought that since they grow underground there wouldn’t be a pesticide issue at all or if there were one it would include the whole sweet potato.

  21. Dana E. says

    This is a good recipe- easy and tasty. One thing you have to watch out for is to use the RIGHT potato! Use a yam versus the sweet potato. The yam is the orange-fleshed tuber, that’s tapered on both ends. The “sweet potatoes” that look more like standard, russet potatoes, with lighter, white-ish colored flesh. The orange “yam” worked great in this recipe. The sweet potato is more “watery,” and I’m not surprised if the chips came out “soggy”.

  22. Dale says

    Ever done it with yucca? Every tried coconut oil instead of olive oil? I have made these tossing with herbs before baking. I personally like herbs de provence.

  23. Akex says

    Wow! You guys are amazing. You never stop surprising me. To prove you I also have a very nice and easy recipe.
    “Toasted bread”
    1. Go to your local Argos shop, get a decent toaster.
    2. On a way home buy a nice pack of sliced bread.
    3. Once at home, plug toaster in.
    4. Make sure socket is on. Put 2 slices of bread in and turn it on. Wait like 2-3 minutes and it’s done!
    Enjoy your toast!

  24. Kelli says

    4 hours later, at 200 degrees and they are STILL Not crispy. I sliced nearly all mine very thin. I see that the author says she updated the recipe to say 300, but as of January 2014, it still says 200. I hope others read the comments before attempting. I wish I had!

    • says

      Kelli, I apologize for the trouble you had with this recipe. I really hope for readers to enjoy the dishes I share! I had added a note a while back regarding the temperature change but you may have overlooked it. Since you commented I have retested the recipe (as you’ll see in the updates above). The new recipe yields more consistent, crispy chips. I hope that helps!

  25. Jean says

    Just tried this recipe, using a mandolin and slicing the potatoes very thin. They started to partially burn at about 1 hour and 20 minutes. (I got busy and forgot to turn them over.) I took them out of the oven thinking I had a disaster on my hands and, surprisingly enough, they were delicious! Even the very brown looking chips were good. I will definitely try the recipe again, maybe slicing the potatoes a little thicker and definitely watching them more closely in the oven.

    • says

      Jean, I personally kind of prefer the brown ones. They seem like they’ll taste burnt but they’re perfect! Glad you enjoyed this recipe.

  26. Leland says

    This can be all over the place. I think it is all about how thick and the consistency of the thickness. I am to lazy to do all the knife work so I got out my electric meat slicer it gives consistently uniform slices in the thickness of your choice and is fast. Also you have to be dilegent, set the timer in smaller increments to check on the progress often

  27. Veronica says

    These were awful. I wasted two sweet potatoes doing this. They took FOREVER to get crispy, over three hours. By the time they were crispy, they were really tiny, definitely not substantial fair as a side dish or part of a main meal, barely enough for one person to snack on. The flavor was nasty. I am never trying this again.

  28. Keith says

    Thanks for the great idea!! I just tried this without the olive oil to reduce the fat and used a little water instead figuring that would at least help to distribute the spices. Worked great! I also baked at 475 degrees to cut the time to under 30 min.

  29. LJ says

    These are in the oven as we speak! I wish I had double ovens because I am doubling the batch :) the first batch has just salt and pepper and the second I will season with some cumin, garlic, and curry powder. We make sweet potato treats for my dogs w/o oil and seasonings, and I never thought to make them for humans until my boyfriend ate one of their dog treats! Can’t wait to see how these turn out!

  30. JESS says

    i made these on a whim on my own . i had acouple sweet potatoes laying aroung and decided to make chips. i sliced them as this and even as i could with a knife. tossed them with some olive oil adobo and garlic powder. sprayed my pan with cooking spray . baked them at 350 for about 20-30 minutes but you have to watch them carefully the first batch i had more brown, wich my dog enjoyed as a treat mixed with his food but the ones that didnt over cook were perfect and crisp. made a secong batch and remembered to hover over the stove and they came out perfect .
    dont give up find your nitch ;)

  31. Robert says

    OK at least we experimented with different temps. Higher temps yielded a bitter result. Back down to 240 degrees worked great. Our chips were uniformly thin because we used our electric mandolin . 30 or so minutes yielded the some crisp and some leathery result. A little sea salt and yum! Will definitely make these part of our nightly snack regimen. Patience folks…just takes a little patience.

  32. Eric says

    Tried this today we LOVED them!!! i always soak the sweet potatoes first in cold water for 20 minutes.They came out amazing! So good!Thanks for the recipe.

  33. Andy says

    Yikes. I wish under ingredients it would’ve included parchment paper. I don’t eat paper it’s just that I was on the go, saw this recipe and thought I had everything I needed.

    From people’s comments it looks like a mandolin would be very handy, and that in general it’s a hit or miss experience.

    I’ve had great experiences with other recipes on this blog but I think I’m just going to make sweet potato fries tonight.

  34. Eileen says

    Epic fail! Husband said ” these are awful ” and he usually likes everything. Followed recipe to the T …. Gross leathery chips!

  35. Claudine McGonigle says

    Have just made a batch of these and they are fab. Used a mandolin to cut the sweet potato.

    This is the only recipe that has worked for me, all the other recipes either provided soggy or burnt chips.

  36. D'Ann Martin says

    One question before I make these. My mandolin has two separate blades for slicing. Should I use the thicker one or the thinner one? The thinner one make the slices almost transparent they are so thin. Not sure… Thanks!

  37. Kerrie says

    Hi There,
    I am wondering if you have had any success cooking root vegetable chips and stored them so they can be had as a snack with dips a day or 2 later?


  38. Laura says

    These turned out OK with orange sweet potatos – nice taste, with a little salt and cayenne = tasty. Keeping this batch for work snacks – this batch turned out a lot like kettle chips, texture-wise. Used my benriner to whittle out thin slices (will aim for even thinner next time), might also crank the gas up above 250 to speed things up if thinner doesn’t do the trick.

  39. says

    Made these and they were great! I used a regular knife to slice them as thin as I could. They got crisp and brown but didn’t burn. Yum! Thanks for sharing this simple, easy recipe!

    I noticed in the comments that a lot of people had problems with them, and I’d like to add that perhaps they piled them on top of each other and that’s why they didn’t crisp up. I didn’t see anyone mention this in the responses, but I think baking them all in a single layer is very important. If they’re not baked in a single layer, they likely won’t get crispy!

  40. Thomas says

    Meh. Ive had much much better. Low temps make it hard to burn but the chips are far too hard. It would be better to cook at a higher temp for a shorter time.

  41. Ainsley says

    I use a recipe similar to this. I usually make mine a little thicker sliced, though. I season them with a little but of salt, pepper, onion powder, and garlic powder. Bake at 400 degrees from 30 min, flipping them half way through. I then broil them on high for 5-7 minutes to get them crispy. It makes for a nice, savory sweet potato chip!

  42. Stephan says

    I made these for the first time and followed the recipe to a T. It’s hard for me because I don’t have a special slicer, so I used two knives. One was a tomato bread slicer and the other was a filet knife for if the sweet potato was two thick. I think 250 degrees is too much for my oven, some came out a little burnt. That being said, I still thoroughly enjoyed them. Even the ones that are a little burnt taste good to me and taste way better than the chips you buy in the store. This is a good recipe. I think the ones that had problems either didn’t cut them thin enough or their oven my be different. All ovens are different and mine gets hot pretty quick even at 250 so next time I’ll try 225.

  43. Whitney says

    Ok, mine turned out *perfect*, better than any other recipe for these that I’ve found. BUT there are some must-do’s and must-not-do’s. Here’s what I did:
    -Use a mandolin slicer!! Mine has a knob you turn and choose a thickness – i did 1/8 of an inch thick. Any thicker and you won’t get crispy, you’ll get leathery (I tested out 1/4 inch thickness, too).
    -I have a convection oven, nothing fancy, just a frigidaire convection. I baked them for an hour at 250 , then flipped and baked for another 40 minutes. When I pulled them out, perfectly crispy and ready to go!
    -If you don’t bake them long enough, they’ll be very chewy and leathery, not crispy. I tested by putting some in for the last 40 minutes – way too tough and leathery!
    Love this recipe! But I think your outcome is dependent on many variables (oven, temp, thickness of each chip, time baked, etc). Just wanted you all to know what I did that worked perfectly.

  44. Sandy Brown says

    I have been making these sweet potato chips on a regular basis, and my family loves them! The first time I tried it, I didn’t use the parchment paper and I found that the burnt chips were more bitter. However, using the parchment paper really helped, and even the burnt ones tasted delightful.

    Thanks for sharing this recipe! It’s nice to have “normal” snacks that the kids can take to school, but don’t have any of the added preservatives and chemicals that the processed foods have.

  45. Addie says

    Made them with mandolin on 1/8, in oven with dark cookie sheet lined with parchment paper. 30 min at 250, turned, then 30 min more. Turned the oven off and left them alone for another 30 or 40 mins. Perfect. I did sample as I went along, and they were doing fine, just not crispy enough. Letting them ‘dry out’ after the oven was off helped a lot. I made a dip with plain greek yogurt, dill, little garlic powder, grated cuke, lemon juice and unsalted seasoning. Great snack! I may try them at higher temp for shorter time, next time, for convenience.

  46. Sarah says

    Extremely disappointed! I followed the directions to a T, thinly sliced the sweet potatoes, flipped during cooking, rotated the racks– they came out almost inedible!!! Tough, leathery, and hard to eat. Waste of good sweet potatoes.

  47. Sherrie says

    Thank you Dana for this blog, and thank you to all people (well; except for one..); the chips turned out great!!!! It was your blog that helped me. After reading all entries, I realized this would be an experiment – I could not just set the timer and walk away. Indeed(!), after the first 12 minutes I realized my oven was too hot – the initial smoking of bottom pan gave it away. I kept turning oven down to match small round oven thermometer of 240 degrees, which turned out to be the perfect temp. I kept turning the slices (some thicker, some thinner) until they reached “crunchy” status- which I can’t describe – you just have to see/feel/sense. My guy loves them… And so do I :).

  48. Renee says

    On your nutrition info it says
    3 serving, per serving 198 calories.
    Please clarify how many ounces per serving equal how many calories if you could since you can’t really say how many chips since they are different sizes.
    Thank you

    • Pat says

      Probably the most important question in the comments section; yet no answer. I guess we’ll have to figure that out ourselves.

  49. Cassie says

    How long do these and other root vegetable chips last? Should they be made the day of serving? Or can I slice them, refrigerate, and cook later??

  50. Molly M says

    You said that the original recipe called for 200 degrees but you changed it to 250 degrees because some people said it wasn’t high enough. I just had the opposite problem: I tried this recipe (on 250 degrees) but only after 1 1/2 hours my chips were completely burnt and inedible. Maybe you could suggest that people keep a closer eye on their chips about halfway through the cooking time since all ovens are different?

  51. Sophia says

    I’ve read through the comments and only one regarded coconut oil. I’m trying it with that for Whole 30 and just wondering what the results could be.

  52. Gladys says

    Tried your no salt added chips, they were great.
    Now those of us who can’t have salt can still enjoy a good chip.
    Keep up the good work.

  53. Joyful says

    These finished in under an hour for me. I flipped them at the 20min mark and took them out at around 45min and they were perfect. They come out better if I leave them for a few hours (or accidentally, a few days!) after slicing so that they are drier when baking. Thanks for the delicious recipe!!

  54. Dana says

    Made these last night and unfortunately they did not turn out well at all. Some of them burned while others remained soft. It might be my oven, it’s old. I will probably try another method.
