How To Make Slow Cooker 4-Ingredient Hamburger Potato Casserole

Step 1: Cook the beef
In a large skillet, cook the ground beef over medium heat for about 6–8 minutes, until fully browned. Drain off any excess grease.

Tip: Don’t skip this step—since the slow cooker holds in moisture, leftover grease can make the dish overly oily. Add a generous amount of black pepper while cooking for extra flavor.

Step 2: Slice the potatoes
Cut the peeled potatoes into thin, even rounds (about 1/8 to 1/4 inch thick).

Tip: Try to keep the slices uniform so they cook evenly. A mandoline slicer works great if you have one.

Step 3: Mix the sauce
In a bowl, whisk together the soup with 1/2 cup of water. The thinner consistency helps the sauce spread evenly through the layers.

Step 4: Layer the casserole

• Bottom layer: 1/3 of the sliced potatoes
• Next: 1/2 of the cooked beef, 1/3 of the soup mixture, and 1/2 cup of cheese
• Repeat: Another 1/3 of the potatoes, the remaining beef, 1/3 of the soup, and another 1/2 cup cheese
• Top layer: Final 1/3 of the potatoes, covered with the remaining soup mixture

Step 5: Cook low and slow
Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until the potatoes are fork-tender.

Step 6: Finish with cheese
About 20–30 minutes before serving, sprinkle the remaining 1 cup of cheese on top. Cover and cook until melted and bubbly. Let the casserole sit uncovered for about 10 minutes before serving to allow the sauce to thicken.

Serve warm and enjoy this hearty, comforting dish!
