Lay a sheet pan with aluminum foil. In a small bowl, microwave the butter and oil for 20 seconds. Lay the carrots on the foil, pour the butter and oil over, the salt, and half of the parsley. Mix well with your hands. Sprinkle some black pepper on top and put in the oven for 15 minutes.
Put on a plate and sprinkle what’s left of the parsley over the carrots.
