This Cheesy Loaded Meatloaf Casserole combines two comfort food favorites into one irresistible dish. The hearty meatloaf base topped with creamy mashed potatoes, melted cheese, and crispy bacon creates a meal that's sure to become a family favorite.

I first made this casserole during a particularly hectic week when I needed something substantial that could stretch for multiple meals. My family devoured it so quickly that I now make a double batch whenever it appears on our menu.

Ingredients

  • 1 lb ground beef: Adds rich flavor and hearty texture. Choose 85/15 lean to fat ratio for best flavor
  • 1/2 cup breadcrumbs: Helps bind the mixture while keeping it tender
  • 1 large egg: Acts as the crucial binder that holds everything together
  • 1/4 cup milk: Adds moisture and helps create a tender texture
  • 1/4 cup finely chopped onion: Provides aromatic flavor. Fresh is best for maximum flavor
  • 1 tsp garlic powder: Infuses savory notes throughout the meatloaf
  • 1 tsp salt: Enhances all the flavors. Use kosher salt for better distribution
  • 1/2 tsp black pepper: Adds just the right amount of spice
  • 1 tbsp Worcestershire sauce: Brings umami depth that makes the meat flavor pop
  • 1/2 cup ketchup: Divided, provides sweetness and tanginess while creating a glaze
  • 2 cups prepared mashed potatoes: Forms the creamy layer. Russet potatoes work beautifully here
  • 1 cup shredded cheddar cheese: Creates that irresistible golden melty top. Sharp cheddar offers best flavor
  • 4 slices cooked bacon: Crumbled, adds smoky crunch. Cook until extra crispy for best texture
  • 2 tbsp chopped green onions: Adds fresh color and mild onion flavor

Step-by-Step Instructions

Preheat the Oven:
Set your oven to 375°F. This moderate temperature allows the meatloaf to cook through without drying out while also giving the cheese topping that perfect melt. Thoroughly grease your baking dish to prevent sticking. A 9×9-inch dish creates ideal thickness.
Make the Meatloaf Base:
Combine all meatloaf ingredients in a large bowl except for half the ketchup which will be reserved for topping. Use clean hands to gently mix until just combined. Overmixing will result in a tough texture so stop as soon as ingredients are evenly distributed. The mixture should hold together when pressed but still feel light.
Form and Bake the Meatloaf Base:
Press the meat mixture into your prepared dish with even pressure creating a level surface. Spread the remaining ketchup in a thin layer across the top which will create a flavorful glaze. Bake for 20-25 minutes until the internal temperature reaches 160°F. The meat should no longer be pink but still juicy.
Add the Topping:
Remove the meatloaf from the oven and carefully drain off any excess fat. Gently spread the mashed potatoes across the top in an even layer. Try warming the potatoes slightly beforehand for easier spreading. Sprinkle with cheese and crumbled bacon distributing evenly for consistent flavor in every bite.
Bake Again:
Return the casserole to the oven for 10-15 minutes watching carefully toward the end. The cheese should melt completely and develop light golden spots. If needed broil for 1-2 minutes at the end for a more golden top but watch carefully to prevent burning.
Garnish and Serve:
Sprinkle with fresh green onions right before serving which adds color and fresh flavor. Allow the casserole to rest for 5-10 minutes before cutting which helps it set up for cleaner slices.

This recipe reminds me of Sunday dinners at my grandmother's house where she would always find ways to transform simple ingredients into something special. The Worcestershire sauce is my secret weapon here—it adds a depth that guests always notice but can never quite identify.
