In a large bowl, combine the broccoli florets, chopped carrots, red bell pepper, and zucchini.
Drizzle the olive oil over the vegetables. Add the dried rosemary, dried thyme, garlic powder, salt, and black pepper. Toss well to ensure all vegetables are evenly coated.
Spread the seasoned vegetables in a single layer on a large baking sheet. Avoid overcrowding the pan for best roasting results.
Roast in the preheated oven for 25-30 minutes, or until the vegetables are tender and slightly caramelized, flipping them halfway through the cooking time.
Serve hot as a delicious side dish.
Notes
Feel free to customize with your favorite seasonal vegetables. Other great additions include sweet potatoes, onions, asparagus, or Brussels sprouts. Adjust roasting time based on the vegetables used.
