This mashed potato-topped hamburger casserole recipe is easy to prepare and bake, and it makes a great family meal. It's a homey mixture of ground beef, topped with mashed potatoes and shredded cheese. It's a simple one-dish meal you'll make again and again.

The seasoned hamburger layer is similar to a meatloaf mixture. I added about 3/4 cup of cream style corn to the casserole just before adding the mashed potato topping. 

If your family can't get enough mashed potatoes, use about 4 cups. Serve with steamed broccoli, cream-style corn, or your family's favorite sides.


  • 1/4 cup bread crumbs (fine and dry)
  • 1/2 cup milk
  • 1 pound ground beef (at least 85% lean)
  • 1 teaspoon salt
  • 1/4 teaspoon pepper
  • 2 tablespoons onion (minced, about 1/2 small onion)
  • 1 large egg
  • 2-4 cups prepared mashed potatoes
  • 3/4 cup sharp cheddar cheese (shredded)
  • Optional: paprika

Steps to Make It

  1. In a small bowl, soak the bread crumbs in milk.

  2. In a large bowl, mix the ground beef with the bread crumb mixture, along with the salt, pepper, onion, and the beaten egg.

  3. Pat the meat mixture into a 9-inch pie plate. Bake at 350 F° for 30 minutes. Remove the ground beef from the oven and carefully pour off the excess fat.

  4. Top the meat with the mashed potatoes; sprinkle with cheese. If desired, sprinkle lightly with paprika.

  5. Return to oven for about 15 minutes longer, or until the cheese is melted and potatoes are thoroughly heated. 

Tips and Variations

  • Before topping the baked ground beef with the mashed potatoes, top it with about 1 cup of cooked corn kernels or about 1/2 to 1 cup of cream-style corn.

  • To brown the cheese topping slightly, turn the oven up to 400 F to 425 F about 5 minutes before the casserole is done.
