Cheesy Hamburger Potato Casserole with Ground Beef and Potatoes

Creamy Hamburger Potato Casserole is a simple, satisfying one-dish meal. Layers of condensed mushroom soup, thinly sliced potatoes, seasoned ground beef, and plenty of melted cheese come together for a hearty comfort-dinner that’s quick to prep and bakes in a single pan.

Serve this casserole with a crisp green salad or steamed broccoli to cut the richness. Soft biscuits or a warm loaf of bread are also great for soaking up the creamy sauce.

This easy hamburger potato casserole is like a heartier scalloped potato dish—only better when you add savory browned beef and melted cheese. It’s a dependable choice when evenings turn cool: most of the work is done during a short prep, and the oven finishes the rest. Chances are you already have the ingredients on hand.

Why this casserole works

• Family friendly: Ground beef, potatoes, and mild cheese appeal to kids and adults alike. The cream of mushroom soup adds richness without overpowering flavors.
• Budget-friendly: It relies on pantry staples and affordable ingredients—ground beef, potatoes, canned soup, and cheese—so it feeds a crowd without breaking the bank.
• Feeds a crowd: The recipe fills a 9×13-inch pan, making it ideal for a larger family or for leftovers the next day. It’s also easy to scale up for more people.

• Condensed cream of mushroom soup for flavor and creaminess (cream of chicken can be used instead).
• Milk (whole or 2%).
• Sour cream for extra richness.

How to make Hamburger Potato Casserole

These steps give a clear, streamlined guide to assembling and baking the casserole.

• Prepare: Preheat the oven to 375°F and heat the oil in a large skillet.
• Cook the onion: Sauté chopped onion until translucent, about 5 minutes.
• Brown the beef: Add ground beef, season with salt and pepper, and cook until no longer pink, about 6–8 minutes. Drain excess fat.
• Make the sauce: Whisk together condensed mushroom soup, milk, sour cream, and Italian seasoning until smooth.
• Assemble: Grease a 9×13-inch baking dish and spread a little of the soup mixture on the bottom.
• Layer: Arrange one-third of the sliced potatoes over the bottom, spread one-third of the soup mixture on top, add half the beef, and sprinkle with 1 cup of shredded cheese.
• Repeat: Add another layer of potatoes, soup, beef, and cheese.
• Finish: Top with the last third of the potatoes, the remaining soup mixture, and the remaining cheese.
• Bake: Cover with foil and bake 45 minutes, then uncover and bake 15 minutes more until the cheese is bubbly and golden.
• Rest: Let the casserole rest 10 minutes before serving so it sets and slices cleanly.

Serving suggestions

Pair the casserole with a big salad, steamed green vegetables, or a simple slaw to balance the richness. Bread or biscuits are perfect for soaking up the creamy sauce, and a light dessert finishes the meal nicely.

How to store leftovers

• Refrigerator: Store cooled leftovers in an airtight container for up to 3 days.
• Freezer: Wrap the assembled or baked casserole tightly in plastic and foil and freeze for up to 3 months. Reheat from frozen (it will take longer) or thaw in the fridge before reheating.
• Reheating: Reheat the whole dish in a 375°F oven until warmed through. Individual portions can be reheated on a baking sheet in the oven or in the microwave in short bursts.
