How to Make Cheesy Loaded Meatloaf Casserole

1. Prepare the Meat Layer

  • Combine ground beef, breadcrumbs, eggs, Worcestershire, salt, and pepper in a large bowl.
  • Mix gently with your hands until just combined—don’t overmix!
  • Press the mixture evenly into a greased 9×13 casserole dish.

2. Add the Layers

  • Mashed Potatoes: Spread a thick layer over the meat.
  • Cheese: Sprinkle shredded cheddar generously on top.
  • Bacon: Add cooked, crumbled bacon. Finish with chopped green onions or herbs if you’d like.

3. Bake

  • Preheat oven to 375°F (190°C).
  • Bake uncovered for 45–50 minutes, or until the meat is cooked through (160°F internal temp).
  • Let rest for 10 minutes before serving so the layers set nicely.

Tips for Success

  • Use Fresh Ingredients: Freshly made mashed potatoes and quality cheese make a big difference.
  • Don’t Overmix the Meat: This keeps it from becoming dense or tough.
  • Even Layers: Smooth out each layer evenly for consistent texture and flavor.
  • Let It Rest: Allowing the casserole to rest makes it easier to slice and serve.

Easy Variations

  • Spicy Twist: Use pepper jack cheese or add red pepper flakes to the meat mixture.
  • Add Veggies: Mix in sautéed onions, bell peppers, or spinach for extra nutrition.
  • Make It Vegetarian: Replace the meat with lentils or chopped mushrooms and use dairy-free cheese and butter.

What to Serve with It

This rich, filling casserole pairs well with lighter, fresh sides:

  • Steamed broccoli, carrots, or green beans
