How to Make It
Preheat the oven to 375°. In a large heatproof skillet, melt the butter with the olive oil over moderately high heat. Add the carrots, salt and pepper and cook until browned all over, turning occasionally, 3 to 4 minutes. Transfer the skillet to the oven and roast the carrots for 6 to 8 minutes, until they are just tender but still crisp in the center. Transfer to a plate and serve.
