Ingredients

For the Meatloaf Layer

• 2 pounds lean ground beef
• 1 cup breadcrumbs
• 2 large eggs
• 1 medium onion, finely diced
• 3 garlic cloves, minced
• ½ cup milk
• 2 tablespoons ketchup
• 1 tablespoon Worcestershire sauce
• 1 teaspoon Italian seasoning
• 1 teaspoon paprika
• 1 teaspoon salt
• ½ teaspoon black pepper

Meatloaf Glaze

• ½ cup ketchup
• 2 tablespoons brown sugar
• 1 tablespoon Dijon mustard

Mashed Potato Layer

• 2 pounds russet potatoes, peeled and cubed
• 4 tablespoons butter
• ½ cup whole milk
• ½ cup sour cream
• 1 teaspoon garlic powder
• Salt and pepper to taste

Topping

• 1½ cups shredded cheddar cheese
• 2 tablespoons chopped fresh parsley
• Optional: sliced green onions

Instructions

Step 1: Prepare the Potatoes

Bring a large pot of salted water to a boil. Add the cubed potatoes and cook for 15–20 minutes until fork tender. Drain thoroughly and return them to the pot.

Mash the potatoes with butter, milk, sour cream, garlic powder, salt, and pepper until smooth and creamy. Cover to keep warm.

Step 2: Make the Meatloaf Mixture

Preheat your oven to 375°F (190°C).

In a large bowl, combine ground beef, breadcrumbs, eggs, onion, garlic, milk, ketchup, Worcestershire sauce, Italian seasoning, paprika, salt, and pepper.

Mix gently until just combined. Avoid overmixing to keep the meatloaf tender.

Step 3: Assemble the Base

Lightly grease a 9×13-inch baking dish.

Spread the meat mixture evenly into the dish, pressing gently into an even layer.

Mix together ketchup, brown sugar, and Dijon mustard to create the glaze. Spread evenly over the meat layer.

Step 4: First Bake

Bake the meatloaf layer for 35 minutes.

Carefully remove excess grease if necessary.

Step 5: Add the Mashed Potatoes

Spread the warm mashed potatoes evenly over the partially cooked meatloaf.

Use a spatula or the back of a spoon to create decorative swirls on top if desired.

Sprinkle the shredded cheddar cheese evenly over the mashed potatoes.

Step 6: Finish Baking

Return the casserole to the oven and bake for an additional 20 minutes, or until the cheese is melted and lightly golden.

For extra browning, broil for 2–3 minutes while watching carefully.

Step 7: Rest and Serve

Allow the casserole to rest for 10 minutes before slicing.

Garnish with fresh parsley and green onions before serving.

Recipe Tips

• Use lean ground beef to reduce excess grease.
• Yukon Gold potatoes also produce wonderfully creamy mashed potatoes.
• Freshly shredded cheese melts more smoothly than pre-shredded varieties.
• Don’t overmix the meat mixture, as this can make the meatloaf dense.
• Let the casserole rest before cutting so the layers hold together.

Variations

Bacon Lover’s Version

Mix cooked crumbled bacon into the mashed potatoes and sprinkle extra bacon over the cheese topping.

Vegetable Loaded

Add finely diced carrots, celery, mushrooms, or spinach to the meat mixture for additional nutrition.

Spicy Version

Include diced jalapeños, cayenne pepper, or pepper jack cheese for extra heat.

BBQ Style

Replace the ketchup glaze with your favorite barbecue sauce and top with smoked cheddar.
