Preheat the oven to 400 degrees Fahrenheit (204 degrees Celsius).
Line a large heavy-duty rimmed baking sheet with parchment paper or a silicone baking mat.
Place the carrots, potatoes, onion, bell pepper, and broccoli into a large mixing bowl.
Drizzle the extra virgin olive oil over the vegetables and toss to coat thoroughly.
Sprinkle the thyme, rosemary, garlic powder, salt, and black pepper over the oiled vegetables and toss again to ensure even distribution of seasoning.
Spread the vegetables in a single, even layer across the prepared baking sheet, ensuring they are not overcrowded to prevent steaming.
Roast in the oven for 35 minutes, using a spatula to turn the vegetables at the 15-minute mark.
Continue roasting until the vegetables are fork-tender and the edges are well-browned.
Remove from the oven and serve immediately while hot.
