To a large skillet on the stove add the ground beef, break the ground beef up and cook it through. Once cooked remove any excess grease from the pan.
Add the cooked ground beef in into a greased 9x13 baking dish. Add in the uncooked rice, diced onion, 1 cup of the cheddar cheese, diced carrots, seasonings, stir well. Cover with foil and bake for 50 minutes.
Remove the foil, sprinkle with the remaining cheese and bake it for an additional 15 minutes.
