Quick and Easy Scalloped Potato Casserole with Ground Beef and Bacon

In a large skillet, cook the bacon over medium heat until crispy. Remove from the skillet and set aside on paper towels to drain. Once cooled, crumble the bacon.
Prepare the Ground Beef:

In the same skillet, use the bacon grease to brown the ground beef over medium heat. Add the diced onion and cook until softened, about 3-4 minutes. Drain excess fat if needed.
Prepare the Scalloped Potatoes:

Follow the instructions on the box of scalloped potatoes. Typically, this involves mixing the potato slices with the seasoning packet and adding water or milk. Pour the prepared scalloped potatoes into a greased baking dish.
Assemble the Casserole:

Stir the cream of potato soup into the cooked ground beef and onion mixture. Spread the beef mixture over the prepared scalloped potatoes in the baking dish.
Add Bacon and Cheese:

Sprinkle the crumbled bacon over the beef mixture. Top with a generous amount of shredded cheese.
Bake the Casserole:

Bake the casserole at 375°F (190°C) for 30-35 minutes, or until the cheese is melted and bubbly, and the edges are golden brown.
