Ingredients

Scale
  • 2 lbs ground beef
  • 1 cup breadcrumbs
  • 1 large egg, lightly beaten
  • 1/2 cup milk
  • 1 small onion, finely chopped
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon dried parsley
  • 1 tablespoon Worcestershire sauce
  • 2 cups pre-cooked, mashed potatoes (prepared with butter and milk)
  • 1 cup shredded sharp cheddar cheese
  • 1/2 cup ketchup or preferred meatloaf glaze

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. In a large bowl, combine the ground beef, breadcrumbs, egg, milk, chopped onion, salt, pepper, parsley, and Worcestershire sauce. Mix gently with your hands until just combined; avoid overmixing.
  3. Press the meat mixture evenly into the bottom of the prepared baking dish to form the meatloaf base layer.
  4. Spread the prepared mashed potatoes evenly over the meatloaf layer. This creates your potato meatloaf casserole layer.
  5. Sprinkle the shredded cheddar cheese over the potato layer.
  6. Spoon the ketchup or glaze evenly over the cheese layer.
  7. Bake for 45 to 55 minutes, or until the internal temperature of the meat reaches 160 degrees Fahrenheit and the cheese is melted and bubbly.
  8. Let the casserole rest for 10 minutes before cutting and serving. This is a great one dish dinner for a crowd.

Notes

  • For meal prep, you can assemble the entire casserole (without baking) up to 24 hours ahead. Cover tightly and refrigerate. Add 10-15 minutes to the baking time if cooking directly from the refrigerator.
  • If you prefer a different flavor profile, substitute the mashed potatoes with cooked, drained macaroni and cheese for a mac and cheese meatloaf casserole variation.
  • Use lean ground beef for a lower fat option in this ground beef casserole.
