This Loaded Potato & Meatloaf Casserole transforms two classic comfort foods into a single layered dish that combines seasoned ground beef with creamy mashed potatoes and melted cheese. The recipe builds a meatloaf base in a baking dish, then tops it with prepared mashed potatoes and cheese, creating a substantial meal that delivers familiar flavors in an innovative format. This approach eliminates the need to prepare separate side dishes while creating appealing visual layers.

Step-by-Step Instructions
Prepare the Foundation
Preheat oven to 375°F (190°C) and grease a large baking dish to prevent sticking.
Create the Meatloaf Layer
In a large bowl, combine ground beef, chopped onion, minced garlic, breadcrumbs, milk, egg, Worcestershire sauce, salt, and pepper. Mix thoroughly and press mixture into the bottom of the greased baking dish. Spread ketchup evenly over the top.
Initial Baking
Bake the meatloaf layer for 25 minutes. This partial cooking ensures the meat is properly cooked before adding the potato layer.
Prepare the Potatoes
Meanwhile, boil sliced potatoes until tender, approximately 15 minutes. Drain thoroughly and mash with sour cream, milk, and butter. Season with salt and pepper to taste.
Assemble the Final Layers
Spread mashed potatoes evenly over the partially cooked meatloaf. Sprinkle shredded cheddar cheese and chopped green onions over the potato layer.
Complete the Cooking
Return to oven and bake for another 20 minutes until cheese is melted and lightly golden.
Rest Before Serving
Allow casserole to rest for 10 minutes before serving. This helps layers set properly and prevents burns from hot filling.
