The 4-Star Ingredients

This recipe proves that you do not need a long ingredient list to create something delicious. Here is what you will need:

Ground beef – 1 pound. Ground beef is the savory, hearty base of this casserole. As it browns, it creates a rich, meaty flavor that forms the foundation of the dish.

Condensed cream of mushroom soup – 1 can (10.5 ounces). Cream of mushroom soup creates the rich, creamy sauce that binds the casserole together. It adds savory depth and a velvety texture.

Frozen hash brown potatoes – 2 cups, thawed. Hash browns add heartiness and a satisfying texture. They absorb the creamy sauce beautifully, becoming tender and flavorful.

Shredded cheddar cheese – 2 cups, divided. Cheddar adds a bold, tangy, savory flavor and creates a beautiful, melted, golden topping.

That is it. Four ingredients. No onions. No garlic. No complicated steps. Just honest, delicious ingredients that come together beautifully.

Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat your oven to 350 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.

Step 2: Brown the Ground Beef

In a large skillet over medium heat, cook the ground beef until browned and fully cooked, breaking it up as it cooks. Drain off any excess grease.

Step 3: Mix the Casserole

In a large bowl, stir together the cooked ground beef, cream of mushroom soup, thawed hash browns, and 1½ cups of the shredded cheddar cheese until well combined.

Step 4: Transfer to the Baking Dish

Spread the mixture evenly into the prepared baking dish.

Step 5: Top with Cheese

Sprinkle the remaining ½ cup of shredded cheddar cheese evenly over the top.

Step 6: Bake

Bake for 25 to 30 minutes, until the casserole is hot and bubbly and the cheese is melted and golden around the edges.

Step 7: Rest and Serve

Let the casserole rest for 5 to 10 minutes before serving.
