Sheet pan roasted vegetables for weekly meal prep are a practical way to turn mixed produce into caramelized, ready-to-eat building blocks for lunches and dinners that hold up well in the fridge for several days.

Instructions
Preheat the oven to 425°F / 220°C. Line a large rimmed sheet pan (about 18×13 in / 46×33 cm) with parchment for easier cleanup (or leave unlined for better browning). For deeper browning, preheat the empty pan in the oven.
Prep the firm vegetables: slice carrots into even coins and cut sweet potato into 1.5 cm / 1/2 in cubes. If using Brussels sprouts, trim and halve. Add to a large mixing bowl.
Add the quicker-cooking vegetables: cut broccoli into bite-size florets, slice bell pepper into strips, and cut red onion into wedges (leave root end barely intact). If using mushrooms or zucchini, prep and add them too.
Season: drizzle olive oil over the vegetables, then add salt, pepper, dried herbs, and garlic powder. Toss thoroughly until everything is lightly coated; add a little more oil only if there are dry spots.
Arrange: spread vegetables on the sheet pan in a single even layer. Place flat sides of thicker carrot coins and sweet potato cubes against the pan for better browning. If crowded, use a second pan.
Roast: roast on the middle rack for 20 minutes. Remove, stir, spread back into a single layer, and rotate the pan. Roast 10–15 minutes more, for a total of about 30–35 minutes.
Check doneness: carrots and sweet potatoes should be fork-tender; broccoli and peppers should have lightly browned edges. If needed, roast 5–10 minutes longer.
Finish: immediately drizzle balsamic vinegar over the hot vegetables and toss gently on the pan. Taste and adjust salt and pepper as needed.
Cool for meal prep: cool on the pan for 15–20 minutes before packing into airtight containers to reduce condensation and sogginess.
