Step-by-Step Instructions

Step 1: Prepare the Meatloaf Layer

Preheat oven to 375°F (190°C).
In a large bowl, combine ground beef, breadcrumbs, onion, garlic, eggs, milk, ketchup, Worcestershire sauce, salt, pepper, and Italian seasoning.
Mix gently until just combined (don’t overwork or the meatloaf will be dense).
Spread the mixture evenly in the bottom of a greased 9×13 baking dish.
Bake uncovered for 25–30 minutes, until cooked through and browned on the edges.

Step 2: Make the Mashed Potatoes

While the meatloaf bakes, boil potatoes in salted water until fork-tender, about 15 minutes.
Drain and mash potatoes until smooth.
Stir in milk, butter, and sour cream. Season with salt and pepper to taste.

Step 3: Assemble the Casserole

Remove the meatloaf base from the oven.
Spread mashed potatoes evenly over the meatloaf layer.
Sprinkle shredded cheddar (and mozzarella if using) on top.

Step 4: Bake and Finish

Return casserole to the oven and bake for 15–20 minutes, until cheese is melted and bubbly.
Garnish with green onions, parsley, or an extra drizzle of ketchup.
Allow to rest for 10 minutes before slicing and serving.

Pro Tips for Success

Don’t overmix the meatloaf – Light mixing keeps it tender.
Use warm milk in potatoes – Prevents them from becoming gummy.
Make ahead – You can assemble the casserole up to a day in advance and refrigerate before baking.
Double the recipe – Great for meal prepping or serving a large group.
Add veggies – Sautéed mushrooms, carrots, or spinach can be mixed into the meatloaf for extra nutrition.

Variations & Customizations

Tex-Mex Twist – Add taco seasoning to the meatloaf and top with pepper jack cheese.
BBQ Style – Replace ketchup with BBQ sauce for a smoky flavor.
Vegetable Boost – Layer sautéed bell peppers, zucchini, or corn between the meatloaf and potatoes.
Spicy Kick – Add jalapeños to the potato layer or sprinkle with red pepper flakes.
Mini Versions – Make in muffin tins for individual servings.

Serving Suggestions

Serve with a crisp green salad to balance the richness.
Pair with roasted vegetables like broccoli, carrots, or green beans.
Add a side of garlic bread for an extra indulgent meal.
For a lighter option, serve smaller portions with a simple cucumber and tomato salad.
