Ingredients You’ll Need

Here’s what to gather before you get started:

  • 3 cups of mashed potatoes (leftover garlic mashed potatoes work great)
  • 1 pound of lean ground beef
  • 1/2 cup finely chopped white onion
  • 3 cloves garlic, minced
  • 2 tablespoons packed brown sugar
  • 1 tablespoon Worcestershire sauce
  • 1 cup Italian-style breadcrumbs
  • 1 large egg
  • 1 1/2 cups grated sharp cheddar cheese
  • 1/3 cup cooked and crumbled bacon (or store-bought bacon bits)
  • Kosher salt, to taste
  • Fresh ground black pepper, to taste

How to Make It

Preheat the oven.
Set your oven to 375°F (190°C) to get started.

Mix the meatloaf base.
In a large bowl, add the ground beef, onion, garlic, brown sugar, Worcestershire sauce, breadcrumbs, and egg. Season it with salt and pepper, then mix everything until evenly combined.

Assemble the casserole.
Grease a 9×13-inch baking dish. Press the meat mixture evenly into the base of the dish. Spread mashed potatoes over the meat layer and smooth it out. Add the cheddar cheese on top, followed by the crumbled bacon.

Bake.
Bake the casserole for 25 to 30 minutes. You’ll know it’s ready when the cheese is melted and slightly golden on top.

Let it rest and serve.
Allow the dish to rest for 5 to 10 minutes before slicing. You can sprinkle fresh herbs over the top before serving, if desired.

Helpful Tips

  • Using leftovers: Mashed potatoes from a previous meal work perfectly in this dish and add extra flavor.
  • Try different cheeses: Swap in mozzarella or Monterey Jack if you prefer a milder or creamier taste.
  • Add veggies: Peas, carrots, or corn can be added to the meat layer for color and nutrition.
  • Want it spicier? Add a few dashes of hot sauce or red pepper flakes to the beef mixture.

What to Serve With It

This dish goes well with a simple green salad, roasted vegetables, or some crusty bread. It’s also satisfying on its own as a full, all-in-one dinner.


Whether you’re making use of leftovers or cooking from scratch, this cheesy loaded meatloaf casserole is an easy win. It’s flavorful, comforting, and sure to become a favorite at the family table.
