Making Herb-Roasted Tri-Colored Carrots is simple if you follow these steps:

1. Preheat Oven: Start by preheating your oven to 400°F (200°C).
2. Prepare Carrots: Wash the tri-colored carrots thoroughly. If they are large, consider cutting them in half lengthwise for even cooking.
3. Season Carrots: In a mixing bowl, combine olive oil, thyme, rosemary, garlic powder, salt, and pepper. Add the carrots to this mixture and toss until they are evenly coated.
4. Arrange on Baking Sheet: Spread the carrots in a single layer on a baking sheet lined with parchment paper.
5. Roast Carrots: Place the baking sheet in the oven and roast for 30-35 minutes. Flip the carrots halfway through for even browning.
6. Check for Doneness: The carrots should be tender and caramelized. Test with a fork to ensure they are cooked through.
7. Garnish and Serve: Once roasted, remove from the oven, adjust seasoning if necessary, and garnish with fresh parsley, if desired.

By following these instructions, you will have perfectly roasted carrots that are sure to delight anyone who tries them.
