Preheat your oven to 425°F (220°C). Gather all your ingredients and equipment.

Combine the carrots with olive oil, salt, and black pepper in a large bowl. Toss gently until well-coated.

Spread the seasoned carrots in a single layer on the baking sheet. Ensure they are spaced apart.

Roast the carrots for 20 minutes, checking halfway for doneness. They should be fork-tender.

In a saucepan, melt butter over medium-low heat. Add honey and cayenne pepper, then stir well and cook for 2-3 minutes until smooth.

Remove the roasted carrots from the oven and toss them with the honey-butter glaze. Garnish with thyme or parsley.
