Add the starchy vegetables (carrots, potatoes, sweet potatoes - Brussels sprouts are optional and should only be added if you like more tender Brussels - otherwise, set aside).
Cover pot or skillet and steam the vegetables for 4-6 minutes or until just tender. A knife should easily pierce the vegetables but not easily slide all the way through. You’re looking for them to be moist and slightly tender.
Transfer the steamed starchy vegetables to one baking sheet, and arrange the non-starchy vegetables on the other baking sheet. Season to taste with salt and curry powder, and toss to coat.
Bake for a total of 20-30 minutes or to desired doneness. The broccolini seems to require just 15 minutes, while the cabbage, bell pepper, and cauliflower benefit from a longer roast - up to 25-30 minutes. (Once steamed), the starchy vegetables shouldn’t need more than 20 minutes in the oven. Steamed Brussels need to be roasted for 15 minutes, while unsteamed Brussels can roast for up to 20-25 minutes. Just watch the oven closely and check for doneness.
At this point, they’re ready to serve! However, I find that the vegetables are enhanced with a bit of fresh lemon juice, some herbs, and a drizzle of tahini.
Store leftover vegetables covered in the refrigerator up to 3-4 days. Reheat over a cast-iron skillet or on a parchment-lined baking sheet in a 400-degree F (204 C) oven until hot - about 10 minutes.
*I roasted my favorite vegetables, but this is by no means an exhaustive guide. I tend to find that starchy vegetables (like potatoes) benefit from a short steam before roasting, while non-starchy vegetables (like peppers, broccoli) should be roasted without steaming for best results. *Nutrition information is a rough estimate calculated without optional serving ingredients. *Brussels sprouts method inspired by my pal Faring Well!
