1. Prepare the Meatloaf
-
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
-
Mix the ingredients: In a large bowl, combine the ground beef, breadcrumbs, milk, egg, onion, ketchup, Worcestershire sauce, garlic powder, thyme, salt, and pepper. Mix until just combined—avoid overmixing to keep it tender.
-
Shape and bake: Form the mixture into a loaf shape and place it in the prepared dish. Bake for 45–50 minutes, or until the internal temperature reaches 160°F (71°C).
2. Make the Mashed Potatoes
-
In a separate bowl, combine mashed potatoes, melted butter, sour cream, and milk.
-
Mix until creamy and smooth. Add more milk if needed, and season with salt and pepper.
3. Assemble and Finish
-
Layer it up: Spread the mashed potatoes evenly over the baked meatloaf.
-
Add cheese: Sprinkle the shredded cheddar on top.
-
Bake again: Return to the oven for 10–15 minutes, until the cheese is melted and bubbly.
-
Garnish and serve: Let the dish rest for 5–10 minutes. Top with chopped green onions if desired. Slice and serve warm.
Cook’s Notes & Tips
-
Don’t overmix: Mixing too much can make the meatloaf dense.
-
Smooth potatoes spread better: Make sure they’re creamy before layering.
-
Cheese swaps: Try mozzarella or Monterey Jack for a milder, creamier flavor.
Variations
-
BBQ Meatloaf: Replace ketchup with barbecue sauce for a smoky kick.
-
Bacon Mashed Potatoes: Stir in crispy bacon bits for extra flavor.
-
Turkey Meatloaf: Use ground turkey instead of beef for a lighter version.
Serving Suggestions
-
Green Salad: Adds a refreshing contrast to the rich flavors.
-
Roasted Vegetables: Carrots, green beans, or Brussels sprouts pair beautifully.
-
Garlic Bread: Ideal for soaking up every delicious bite.
