Follow these simple steps to create your own Beef and Potato Casserole:

1. Preheat your oven to 350°F (175°C).
2. Brown the Beef: In a skillet, cook the ground beef over medium heat until browned, then drain any excess fat.
3. Sauté Onion: Add chopped onion to the skillet and cook until translucent.
4. Combine Ingredients: In a large bowl, mix the browned beef and onion with cream of mushroom soup, milk, garlic powder, salt, black pepper, and paprika.
5. Layer the Potatoes: In a greased 9×13-inch baking dish, layer half of the sliced potatoes evenly.
6. Add Meat Mixture: Pour half of the meat mixture over the first layer of potatoes.
7. Repeat Layers: Repeat the layers with the remaining potatoes and then the rest of the beef mixture.
8. Add Cheese: Top the casserole with shredded cheddar cheese, ensuring it covers the entire surface.
9. Cover with Foil: Loosely cover the baking dish with aluminum foil to prevent over-browning.
10. Bake: Place the casserole in the preheated oven and bake for 30 minutes covered.
11. Uncover and Continue Baking: Remove the foil and bake for an additional 30 minutes, or until the cheese is bubbly and golden.
12. Cool and Serve: Allow the casserole to cool for 10 minutes before serving.

With these steps, you’ll create a truly delicious Beef and Potato Casserole that bursts with flavor!
