Creamy homemade mashed potatoes top a moist and flavorful meatloaf in this easy casserole dinner. Bacon and cheddar make it even better! Yes, this Loaded Potato and Meatloaf Casserole checks all the boxes, and then some!
Preheat the oven to 375°F. Spray a 9x13 inch pan with nonstick cooking spray and set aside.
In a large mixing bowl, combine the hamburger, onion, garlic, bread crumbs, Worcestershire sauce, egg, cottage cheese, and BBQ sauce.
Add the meatloaf into the pan, and spread it into an even layer. Place in the oven, and bake for 30 minutes.
While the meatloaf is cooking, add the potatoes to a pan and cover with water. Cook over medium heat until tender.
Drain the water from the potatoes, and add the butter. Beat with a hand mixer to combine. Add the sour cream, warm milk, salt, and pepper, and mix again to combine.
Remove the meatloaf from the oven, and pour off any excess grease.
Spread the mashed potatoes over the meatloaf, then add the cheddar cheese and bacon bits.
Return the meatloaf into the oven for an additional 15 minutes, until the potatoes are hot and the cheese has melted.
Remove the pan from the oven, and serve the meatloaf with your favorite sides.
