Ingredients

You only need a few simple ingredients to make this delicious crockpot hamburger potato casserole.

1½ pounds ground beef
6 medium russet potatoes, peeled and thinly sliced

2 cups shredded cheddar cheese (or Colby Jack), divided
1 teaspoon salt (optional)
½ teaspoon black pepper (optional)
Nonstick cooking spray or butter for greasing the slow cooker

How to Make Slow Cooker Hamburger Potato Casserole

This easy crockpot casserole comes together with simple layers.

1. Prepare the Slow Cooker

Lightly grease the inside of a 5- to 6-quart slow cooker with nonstick spray or butter to prevent sticking.

2. Cook the Ground Beef

In a large skillet over medium-high heat, cook the ground beef for 6–8 minutes, breaking it apart as it cooks until browned and no longer pink.

Drain any excess grease and season with salt and pepper if desired.

3. Slice the Potatoes

Peel the russet potatoes and slice them into thin rounds (about ⅛–¼ inch thick). Thin slices help the potatoes cook evenly in the slow cooker.

4. Prepare the Sauce

In a bowl, mix the cream of mushroom soup with ½ cup water until smooth. This helps the sauce spread evenly through the casserole.

5. Layer the Casserole

Start layering the ingredients in the slow cooker:

Add one-third of the sliced potatoes in an even layer.
Spoon half of the cooked ground beef over the potatoes.
Spread one-third of the soup mixture over the beef.
Sprinkle ½ cup shredded cheese on top.

Repeat the layers with another third of the potatoes, the remaining beef, another third of the soup mixture, and another ½ cup cheese.

Finish with the final layer of potatoes and pour the remaining soup mixture evenly over the top.

6. Cook the Casserole

Cover with the lid and cook:

LOW for 6–7 hours, or
HIGH for 3–4 hours

The casserole is done when the potatoes are fork-tender and the edges are bubbling.

7. Add the Final Cheese Layer

About 20–30 minutes before serving, sprinkle the remaining 1 cup shredded cheese over the top.

Cover again and cook until the cheese is fully melted and bubbly.

8. Let It Rest and Serve

Remove the lid and allow the casserole to rest for 5–10 minutes to thicken slightly.

Scoop into bowls and serve warm.

Tips for the Best Crockpot Hamburger Potato Casserole

Slice potatoes thinly
Thin slices cook faster and become perfectly tender.

Brown the beef first
