Roasted Rainbow Vegetables
Colorful, tender-crisp roasted vegetables with caramelized edges, garlic, herbs, and a touch of lemon. An easy healthy side dish that pairs beautifully with chicken, fish, beef, or a grain bowl.
Ingredients
- 1 red bell pepper, cut into chunks
- 1 yellow bell pepper, cut into chunks
- 1 orange bell pepper, cut into chunks
- 1 medium zucchini, sliced
- 1 medium red onion, cut into wedges
- 1 cup broccoli florets
- 1 cup cauliflower florets
- 2 medium carrots, peeled and cut into thick sticks
- 2–3 tablespoons olive oil
- 3 cloves garlic, minced
- 1 teaspoon Italian seasoning
- ½ teaspoon paprika
- ½ teaspoon dried oregano
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 1 tablespoon fresh lemon juice
- 2 tablespoons fresh parsley, chopped
Instructions
- Preheat the oven to 425°F (220°C). Line a large baking sheet with parchment paper.
- Prepare the vegetables: Wash and cut all vegetables into similarly sized pieces so they roast evenly.
- Make the seasoning: In a small bowl, whisk together olive oil, minced garlic, Italian seasoning, paprika, oregano, salt, and black pepper.
- Season: Place all vegetables in a large bowl. Pour the seasoned olive oil over them and toss thoroughly until every piece is lightly coated.
- Spread out: Arrange the vegetables in a single layer on the baking sheet. Avoid overcrowding the pan—use two baking sheets if necessary.
- Roast: Bake for 25–35 minutes, tossing the vegetables halfway through cooking.
- Check for doneness: The vegetables should be tender inside with browned, caramelized edges. For extra browning, broil for 1–2 minutes at the end while watching closely.
- Finish: Remove from the oven and drizzle with fresh lemon juice. Sprinkle with chopped parsley.
- Serve: Serve immediately while warm.
Tips for Perfect Roasted Vegetables
- Cut harder vegetables such as carrots and cauliflower slightly smaller than zucchini and peppers.
- Don’t overcrowd the baking sheet; space helps the vegetables roast instead of steam.
- For extra caramelization, roast at 425°F–450°F (220–230°C).
- Add fresh parsley and lemon after roasting for the freshest flavor.
- For a cheesy finish, sprinkle with Parmesan or feta just before serving.

Q&A
Can I use different vegetables?
Yes. Mushrooms, asparagus, Brussels sprouts, cherry tomatoes, sweet potato, or green beans work well.
Can I make these without oil?
Yes, although the vegetables won’t caramelize quite as well. You can lightly coat them with cooking spray or use a small amount of broth.
Can I add cheese?
Absolutely. Feta, Parmesan, or goat cheese are excellent additions.
Can I make these ahead?
Yes. Roast the vegetables and refrigerate them for up to 4 days. Reheat in the oven or air fryer for better texture.
Can I freeze roasted vegetables?
You can, but the zucchini and peppers may become softer after thawing. For best results, freeze firmer roasted vegetables and reheat them in the oven.
What can I serve with them?
They pair well with grilled chicken, roasted fish, steak, eggs, quinoa, rice, or a simple Greek yogurt sauce.
