Creating Balsamic Roasted Fennel and Carrots is straightforward if you follow these steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Prepare Vegetables: Trim the fennel bulbs and cut them into wedges. Peel the carrots and slice them diagonally into uniform pieces.
3. Mix Oil and Vinegar: In a large bowl, whisk together the olive oil, balsamic vinegar, thyme, salt, and black pepper.
4. Combine Vegetables: Add the fennel wedges and carrot slices to the bowl and toss until they are well coated with the balsamic mixture.
5. Arrange on Baking Sheet: Spread the coated vegetables in a single layer on a baking sheet lined with parchment paper for easy cleanup.
6. Roast Vegetables: Place the baking sheet in the preheated oven and roast for 25-30 minutes, flipping once halfway through, until the vegetables are tender and caramelized.
7. Garnish and Serve: Once roasted, remove the vegetables from the oven. Sprinkle with fresh parsley if desired before serving.

Following these clear steps will ensure your Balsamic Roasted Fennel and Carrots turn out perfectly every time.
