Golden Nugget Casserole Recipe

Preheat oven to 350°. Crumble ground beef into large skillet; add onion. Cook over medium-high heat, stirring frequently, until beef is well browned and thoroughly cooked, 5 - 7 minutes. Stir soup mix and flour into beef. Add water; continue cooking, stirring constantly, until thickened. Spoon beef mixture into 9 inch square baking dish. Sprinkle cheese over beef. Arrange nuggets over cheese. Bake until potato nuggets are golden brown and mixture is bubbly, about 30 to 40 minutes.
