Step‑by‑Step Instructions for Cheesy Loaded Meatloaf Casserole Step 1: Preheat the Oven Begin by preheating your oven to 400ºF (200ºC). This will ensure that your Cheesy Loaded Meatloaf Casserole bakes evenly and crisps up perfectly on top. While the oven is warming up, gather your baking dish and all the ingredients needed for the recipe. Step 2: Prepare the Meat Mixture In a large mixing bowl, combine the lean ground beef, finely chopped white onion, minced garlic, brown sugar, and Worcestershire sauce. Use your hands or a spatula to mix these ingredients thoroughly until they’re well integrated, with no visible pockets of onion or garlic. This step ensures that all the flavors meld together beautifully. Step 3: Season and Bind the Mixture Next, season your meat mixture with kosher salt and freshly ground black pepper to taste. Gently fold in Italian breadcrumbs and the large egg, mixing until everything is evenly combined. The breadcrumbs will not only add flavor but also bind the meat mixture, creating the comforting base for your casserole. Step 4: Assemble the Casserole Transfer the prepared beef mixture into an 8-inch square baking dish, using a spatula to spread it evenly and pack it down gently. Make sure the layer is uniform to allow for even cooking. This hearty base is the foundation of your Cheesy Loaded Meatloaf Casserole, ready to support the delicious toppings. Step 5: Spread the Mashed Potatoes Take your cold garlic mashed potatoes and evenly spread them over the beef layer. Use a spatula to create a smooth, even layer, covering the meat completely. This creamy topping not only adds texture but also infuses the casserole with delicious garlic flavor, making every bite a treat. Step 6: Add Cheese and Bacon Sprinkle a generous amount of grated sharp cheddar cheese over the mashed potatoes, followed by the cooked and crumbled bacon or bacon bits. Make sure to cover the entire surface, creating a delightful cheesy and crunchy top layer that will melt and crisp up beautifully during baking. Step 7: Cover and Bake Cover the assembled casserole loosely with aluminum foil, ensuring it doesn’t touch the cheese. Place it in the preheated oven and bake for 30 minutes. This step allows the flavors to meld together and keeps the top from browning too soon, ensuring a perfectly cooked center. Step 8: Remove Foil and Brown the Top After 30 minutes, carefully remove the foil and continue to bake for an additional 10–15 minutes. Keep an eye on your Cheesy Loaded Meatloaf Casserole as it bakes—it’s ready when the cheese is melted, bubbly, and lightly golden on top, indicating a beautiful, delicious finish. Make Ahead Options These Cheesy Loaded Meatloaf Casserole are perfect for meal prep enthusiasts! You can assemble the entire casserole up to 24 hours in advance and store it covered in the refrigerator. To prevent the mashed potatoes from browning, keep the layers well separated until you’re ready to bake. Alternatively, for longer storage, you can freeze the assembled casserole for up to 3 months. When ready to serve, simply thaw it overnight in the fridge before baking. Cook as directed (approximately 40-45 minutes total), and you’ll have a comforting family meal that is just as delicious as if it were freshly made, saving you precious time on busy weeknights!

Cheesy Loaded Meatloaf Casserole Recipe FAQs What type of ground beef should I use for this casserole? For the best flavor and texture in your Cheesy Loaded Meatloaf Casserole, lean ground beef is recommended, usually around 80/20 for optimal juiciness without excess grease.

You can store leftover Cheesy Loaded Meatloaf Casserole in an airtight container in the refrigerator for up to 4 days.
