Peel and trim your carrots. Cut them into 3- to 4-inch pieces and cut them in half as needed. The goal is to have carrot pieces that are similar in size so that they cook evenly.
Preheat the oven to 400℉.
Add the oil to a large cast iron or oven proof skillet over medium high heat. When the oil is shimmering, add the carrots, cut side down.
Let the carrots sear until charred, about 3 minutes. Remove the pan from the heat and turn the carrots over so that the seared side is up.
Place the pan in the oven and let the carrots bake until they are tender, about 15 minutes.
Add salt and pepper to taste and serve hot.
Notes
Using larger whole carrots saves yourself some time peeling and cutting.
Be sure to cut the carrots into fairly uniform pieces so they cook evenly.
This recipe is best served fresh but you can peel and cut up the carrots a day or two before and store them in an airtight container in the fridge.
A little bit of good quality hard cheese (such as Parmesan) grated right on top just before serving is amazing on these but not necessary (or pictured).
