Creating the incredible Easy Hamburger Potato Casserole is straightforward. Just follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) to prepare for baking.
2. Cook the Ground Beef: In a skillet over medium heat, brown the ground beef with the chopped onion until the beef is no longer pink. Drain any excess fat.
3. Season the Beef: Add garlic powder, salt, pepper, and paprika (if using) to the cooked beef. Mix well to combine flavors.
4. Prepare the Potatoes: Slice the potatoes thinly and set them aside. You can use a mandoline slicer for even slices.
5. Grease the Baking Dish: Lightly grease a 9×13-inch baking dish to prevent sticking.
6. Layer the Ingredients: Begin layering the ingredients as follows:
– Start with half of the sliced potatoes at the bottom of the dish.
– Evenly spread half of the beef mixture over the potatoes.
– Pour half of the cream of mushroom soup mixed with milk over the beef.
– Sprinkle with one cup of shredded cheddar cheese.
– Repeat the layers with the remaining potatoes, beef, soup mix, and cheese.
7. Cover and Bake: Cover the dish with aluminum foil and bake for 30 minutes in the preheated oven.
8. Uncover and Add Cheese: After 30 minutes, remove the foil and top with the remaining cheese. Bake uncovered for an additional 15 minutes or until the cheese is bubbly and golden.
