Friends, are you ready for a flavor bomb?! I hope so, because that’s what you’re going to get with these Balsamic-Marinated Portobello Pizzas. Swoon!
Plus, just 10 simple ingredients required for this savory, satisfying entrée or side. Let’s do this!
I shared a similar recipe on the blog years ago, but the concept has been much improved here!
This new version begins with marinating hearty portobello mushrooms in balsamic vinegar, olive oil, salt, and red pepper flake (optional). While that’s happening, you can prep your veggies, make vegan cheese (or use store-bought), and prepare / ready your red sauce of choice.
Toppings include a simple red sauce, roasted veggies, and whole garlic cloves for ultimate flavor, plus our go-to 5-minute Macadamia Nut Cheese. This combination of flavors — paired with an optional balsamic drizzle — sends these pizzas over the top! I can’t wait for you all to try them.
We hope you LOVE these pizzas! They’re:
BIG on flavor
& So delicious!
These would make the perfect entrée when you enjoy 2 pizzas paired with a side salad. Or serve as a side paired with other Italian favorites like our Vegan Pesto Parmesan Breadsticks, Vegan Sun-Dried Tomato Arancini, Best Vegan Meatballs, or Eggplant Lasagna Roll-Ups!

Balsamic-Marinated Portobello Pizzas
- 4 large portobello mushrooms (stems removed, wiped clean)
- 1/4 cup balsamic vinegar
- 2 Tbsp avocado or olive oil
- 1 pinch salt and pepper (or red pepper flake)
- 1 medium red bell pepper (cut into bite-size pieces)
- 1 small red onion (thinly sliced wedges or diced)
- 1 head garlic (cloves separated and peeled)
- 2 Tbsp avocado or olive oil
- 1 healthy pinch sea salt and black pepper (or red pepper flake)
- 2 Tbsp fresh herbs (such as rosemary or oregano // optional)
- 3/4 cup pizza sauce*
- 1/2 cup sun-dried tomatoes (if large, chop into smaller pieces // we prefer Trader Joe’s brand)
- 1/3 cup soft vegan cheese (divided // try our Macadamia Nut Cheese or store-bought Kite Hill Ricotta or Treeline)
FOR SERVING optional
- Fresh Basil
- Balsamic Reduction*
- Red pepper flake
- Vegan Parmesan Cheese
- Preheat oven to 400 degrees F (204 C) and line a large baking sheet with parchment paper. Set aside.
- Add portobello mushrooms (stem side up) to a shallow dish or large freezer bag. Add the balsamic vinegar, oil, salt and pepper (or red pepper flake). Use a pastry brush to brush on all sides (or shake bag to coat). Marinate on one side for 5 minutes, then the other side for 5 minutes.
- In the meantime, add vegetables and garlic to baking sheet, toss with oil, salt and pepper, and fresh herbs (optional) and bake for 20-25 minutes or until golden brown and fragrant, tossing once near the halfway point to ensure even baking. Set aside but keep oven at 400 F (204 C).
- If serving with balsamic reduction (see notes) and/or soft nut cheese (see links above), prepare at this time.
- Heat a large skillet over medium heat (you could also use a grill for this step). Add mushrooms to the pan, leaving any leftover oil-and-vinegar marinade behind. Cook on each side for about 4-5 minutes, or until caramelized and softened. If your mushrooms are extra thick, covering with a lid can be helpful to encourage even cooking all the way through. Brush on any remaining marinade while cooking to infuse more flavor.
- Once mushrooms and vegetables are cooked, assemble pizzas. Place mushrooms on a parchment-lined baking sheet or baking pan and add toppings, starting with pizza sauce, then roasted veggies, roasted garlic, and soft vegan cheese. You can also add vegan parmesan cheese or red pepper flake at this point (optional).
- Bake for about 15-20 minutes or until hot. The soft vegan cheese will be slightly golden brown on top. Remove from oven and enjoy as is, or garnish with sun-dried tomatoes, fresh basil, balsamic drizzle, red pepper flake, and extra vegan parmesan (all optional).
- Best when fresh, though leftovers will keep covered in the refrigerator up to 3-4 days. Reheat in a 350 degree F (176 C) oven until hot.
*For the red sauce, we adapted Smitten Kitchen’s favorite red sauce, straining one 28-ounce jar whole peeled San Marzano tomatoes for 2 hours and discarding the liquid that drained out. Strained tomatoes are blended with 3-4 Tbsp (1 small handful) basil, 1-2 cloves garlic, and salt to taste.
*To make the balsamic reduction, add 1 cup (240 ml) balsamic vinegar to a small saucepan. Bring to a gentle boil. Allow to simmer until it is reduced by half and appears slightly syrupy (about 10-15 minutes). Watch carefully near the end as it can go from reduced to burnt quickly. You’ll know it’s done when it coats the sides of the pan when swirled. Remove from heat and let cool where it will continue to thicken. Store leftovers in the refrigerator for 2 weeks (sometimes longer).
