How to Make Loaded Potato and Meatloaf Casserole: Step-by-Step
1. Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. Make the Meatloaf Base
In a large bowl, mix together ground beef, chopped onion, minced garlic, egg, milk, breadcrumbs, Worcestershire sauce, salt, and pepper until just combined. Do not overmix.
Press the mixture evenly into the bottom of the prepared baking dish to form a uniform layer.
3. Bake the Meatloaf
Bake uncovered for 20–25 minutes, or until the meatloaf is mostly cooked through and firm.
While it bakes, prepare the mashed potatoes.
4. Make the Mashed Potato Layer
Boil peeled and cubed potatoes in salted water until fork-tender (about 15–20 minutes). Drain well.
Mash with butter, warm milk, and sour cream until smooth and fluffy. Season with salt and pepper to taste.
5. Assemble the Casserole
Once the meatloaf is baked, carefully spread the mashed potatoes over the top in an even layer.
Sprinkle shredded cheddar cheese over the mashed potatoes, followed by chopped bacon.
6. Finish Baking
Return the dish to the oven and bake for another 10–15 minutes, or until the cheese is melted and bubbly.
7. Garnish and Serve
Sprinkle green onions on top just before serving. Let rest for 5–10 minutes to set before slicing.
