Ingredients You’ll Need

This recipe keeps things straightforward without sacrificing flavor.

Main Ingredients

1 lb ground beef
½ medium onion, diced
½ teaspoon garlic powder
½ teaspoon salt
¼ teaspoon black pepper
4 cups thinly sliced potatoes (about 3–4 russet potatoes)
1 (10.5 oz) can cream of mushroom soup
½ cup sour cream
½ cup milk
2 cups shredded cheddar cheese, divided

Optional Topping

½ cup crushed Ritz crackers or French fried onions

How to Make Cheesy Hamburger Potato Casserole

Step 1: Prep the Oven and Dish

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking.

Step 2: Cook the Beef

In a skillet over medium heat, cook the ground beef and diced onion for about 6–7 minutes, until the beef is browned and the onion is soft. Drain any excess grease. Season with garlic powder, salt, and black pepper, then set aside.

Step 3: Make the Creamy Sauce

In a mixing bowl, whisk together the cream of mushroom soup, sour cream, and milk until smooth and well combined. This creamy mixture is what keeps the casserole moist and flavorful.

Step 4: Assemble the Layers

Layering is key to even cooking and maximum flavor:

Arrange half of the sliced potatoes in an even layer in the baking dish
Top with half of the beef mixture
Pour over half of the creamy sauce
Sprinkle 1 cup of shredded cheddar cheese

Repeat the layers with the remaining potatoes, beef, sauce, and cheese.

Step 5: Bake

Cover the dish tightly with foil and bake for 60 minutes. Remove the foil and bake an additional 15–20 minutes, until the potatoes are fork-tender and the top is golden and bubbly.

If using the optional topping, sprinkle it on during the last 10 minutes of baking.

Step 6: Rest and Serve

Let the casserole rest for 10 minutes before serving. This helps it set and makes slicing easier.
