1️⃣ Preheat the oven to 400°F (200°C).

2️⃣ Prepare the mashed potatoes: In a medium saucepan, bring 1 1/2 cups water and 1/2 cup milk to a boil. Remove from heat and stir in the garlic-flavored instant mashed potato powder until smooth. Set aside.

3️⃣ Mix the meatloaf base: In a large mixing bowl, combine the ground beef, diced onions, brown sugar, and Worcestershire sauce. Mix well using your hands.

4️⃣ Add the binding ingredients: Add the seasoned bread crumbs and egg to the meat mixture, continuing to mix with your hands until fully incorporated.

5️⃣ Form the meatloaf: Press the meat mixture evenly into the bottom of an 8-inch square baking dish, creating an even layer.

6️⃣ Layer the mashed potatoes: Using a rubber spatula, spread the prepared mashed potatoes evenly over the top of the meat mixture.

7️⃣ Top with cheese and bacon: Sprinkle the shredded cheddar cheese over the mashed potatoes, then sprinkle the real bacon bits on top.

8️⃣ Bake covered: Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes.

9️⃣ Finish baking uncovered: Remove the foil and continue baking for an additional 10 minutes, until the cheese is melted and bubbly.

🔟 Cool and serve: Remove from the oven and let the casserole cool for a few minutes before slicing and serving.
