Ingredients
Method
- Step 1: Preheat and Prepare
Preheat the oven to 375°F (190°C). Grease a 9×9-inch baking dish or line it with parchment paper. - Step 2: Mix the Meatloaf
In a large bowl, combine the ground beef, breadcrumbs, milk, egg, ketchup, garlic powder, onion powder, salt, and pepper. Mix gently until just combined. - Step 3: Bake the Meatloaf Layer
Press the meat mixture evenly into the prepared dish and bake uncovered for 20–25 minutes. - Step 4: Prepare the Mashed Potatoes
While the meatloaf bakes, warm the mashed potatoes and stir in the sour cream and butter. Season with salt and pepper to taste. - Step 5: Assemble the Layers
Spread the mashed potatoes evenly over the baked meatloaf layer. - Step 6: Add Cheese and Bake Again
Top with shredded cheddar cheese and bake an additional 10–15 minutes, until the cheese is melted and bubbly. - Step 7: Rest and Serve
Let the casserole cool for 5–10 minutes. Garnish with chopped parsley, slice, and serve warm.
Notes
For extra flavor, mix a little Worcestershire sauce or chopped onion into the meatloaf base. You can also substitute ground turkey or chicken for a lighter option.
