Ingredients

- 2 large carrots, sliced into rounds
- 1 red bell pepper, chopped into bite-size pieces
- 1 yellow bell pepper, chopped into bite-size pieces
- 1 medium red onion, cut into wedges
- 1 cup broccoli florets
- 3 tablespoons olive oil
- 3 cloves garlic, minced
- 1 teaspoon dried rosemary
- 1 teaspoon dried thyme
- 1 teaspoon salt
- ½ teaspoon black pepper
Instructions
Preheat your oven to 400°F (200°C). In a large mixing bowl, combine the carrots, bell peppers, red onion wedges, and broccoli florets. Drizzle the olive oil over the vegetables, then toss to coat them evenly. Sprinkle in the garlic, dried rosemary, dried thyme, salt, and black pepper. Gently stir the mixture again, ensuring every piece is well-seasoned.

Spread the vegetables out on a large baking sheet so they’re in a single layer; this helps them roast evenly. Slide the tray into the preheated oven and let everything cook for about 20 to 25 minutes, or until the vegetables are golden and tender. Keep an eye on them toward the end of baking so they don’t over-brown—some crisp edges are perfect, but too much charring can overpower the flavor.
Once finished, transfer the roasted vegetables to a serving dish. If you’d like an extra pop of freshness, garnish with chopped parsley or a squeeze of lemon juice. This step can lift the flavors even more, but is entirely optional.

These Garlic-Herb Rainbow Roasted Vegetables are perfect for anyone craving a satisfying, veggie-forward dish. They’re easy to adapt if you need gluten-free or dairy-free options—simply ensure your seasonings are certified gluten-free, and skip any butter additives.
Feel free to swap in different vegetables like squash, Brussels sprouts, or sweet potatoes, if preferred. Enjoy the versatility, simplicity, and health benefits of this hearty recipe, and have fun experimenting with herbs and spices for an endlessly customizable meal.
