Ingredients
- 1 pound of ground beef
- 1 small onion, diced
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 30 ounces of frozen hashbrowns, thawed
- 1 cup sour cream
- 1 can (10.5 ounces) cream of mushroom soup
- 2 cups shredded cheddar cheese (divided)
- 1 cup shredded mozzarella cheese
- Optional: chopped green onions or parsley for garnish
Directions
- Preheat the Oven: Begin by preheating your oven to 350°F (175°C). This allows your casserole to cook evenly.
- Cook the Ground Beef: In a large skillet over medium heat, brown the ground beef along with the diced onion. Make sure to break the meat into small crumbles while cooking.
- Season the Meat: Once the meat is browned, drain any excess fat. Stir in the garlic powder, onion powder, salt, and black pepper. Cook for another minute until well combined.
- Mix the Casserole Ingredients: In a large mixing bowl, combine the thawed hashbrowns, sour cream, cream of mushroom soup, and half of the cheddar cheese. Stir until all ingredients are well incorporated.
- Combine the Beef with Hashbrown Mixture: Add the cooked beef and onion mixture into the hashbrown mixture. Mix thoroughly to ensure every part of the casserole is flavorful.
- Transfer to Baking Dish: Grease a 9×13 inch baking dish. Spread the hashbrown and beef mixture evenly in the dish.
- Top with Cheese: Sprinkle the remaining cheddar cheese and mozzarella cheese over the top of the casserole.
- Bake to Perfection: Place the baking dish in the oven and bake for 45 minutes, or until the cheese is bubbly and golden brown.
- Cool and Serve: Once out of the oven, let the casserole sit for about 10 minutes before serving. This will help it set and be easier to serve.
- Garnish: If desired, top with chopped green onions or parsley for a pop of color and added flavor.
