Ingredients

Scale
  • 2 lbs ground beef
  • 1 cup bread crumbs
  • 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
  • 1 cup shredded cheddar cheese, divided
  • 2 cups cooked, mashed potatoes (prepared with butter and milk)
  • 1/2 cup sour cream
  • 1/4 cup milk
  • 1/4 cup butter, melted
  • 1/2 cup shredded Monterey Jack cheese

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, bread crumbs, egg, 1/2 cup milk, chopped onion, salt, pepper, parsley, and Worcestershire sauce. Mix gently with your hands until just combined; do not overmix.
  3. Press the meat mixture evenly into the bottom of the prepared baking dish. Sprinkle 1/2 cup of the cheddar cheese over the meat layer.
  4. In a separate bowl, mix the mashed potatoes, sour cream, 1/4 cup milk, and melted butter until smooth. Spread this potato mixture evenly over the cheese layer.
  5. In a small bowl, mix the remaining 1/2 cup cheddar cheese with the Monterey Jack cheese. Sprinkle this cheese blend over the potato layer.
  6. Bake for 40 minutes, or until the meat is cooked through and the cheese is melted and lightly golden.
  7. Let the meatloaf casserole rest for 5 minutes before you cut and serve it.

Notes

  • For a quicker prep, use refrigerated pre-made mashed potatoes.
  • You can prepare the entire casserole, cover it, and refrigerate it for up to 24 hours. Add 10-15 minutes to the baking time if cooking directly from the refrigerator.
  • Add cooked, crumbled turkey bacon to the cheese topping for extra flavor.
