Preheat the oven to 350 F. In a medium-sized skillet, brown the ground beef until no pink is left.

In a large bowl, combine the cooked ground beef, frozen cubed potatoes with onion and bell peppers, condensed cream of celery soup, cream of cheddar soup, one cup of shredded cheddar cheese, salt, and pepper to taste.

Spoon the mixture into a 9 x 13-inch casserole dish.

Sprinkle the remaining cup of cheddar evenly on top. Cover with foil and bake for 30 mins. Remove the foil and cook an additional 15 mins until the cheese is melted.
