Toss together carrots, cauliflower, oil, thyme, garlic, salt and pepper in a bowl.
Spread vegetables on a foil or baking mat-lined baking pan.
Roast for 40 minutes or until tender.
Notes
Uniform Slicing: Try to cut the carrots and cauliflower into uniform-sized pieces to ensure even cooking. This helps prevent some pieces from becoming overly soft while others remain undercooked.
Adjust Seasonings: Feel free to adjust the seasoning quantities according to your taste preferences. If you enjoy a stronger thyme flavor, you can increase the amount of thyme used. Similarly, you can adjust the salt and pepper levels to suit your taste.
Check for Doneness: Oven temperatures and vegetable sizes can vary, so it's essential to check the vegetables for doneness periodically while they roast. Use a fork or knife to pierce the carrots and cauliflower pieces. They should be tender and easily pierced when they are ready. If they still feel firm, continue roasting for a few more minutes until they reach the desired tenderness.
