Creating this Cheesy Ground Beef & Potato Casserole is easy. Just follow these simple steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Beef: In a skillet, heat the olive oil over medium heat. Add chopped onions and minced garlic, cooking until softened.
3. Brown the Beef: Add the ground beef to the skillet. Season with salt, pepper, and paprika. Cook until fully browned, breaking it up into small pieces.
4. Combine Ingredients: In a bowl, mix the cream of mushroom soup and milk until smooth. Set aside.
5. Layer Potatoes: In a greased 9×13 inch casserole dish, layer half the sliced potatoes at the bottom.
6. Add Beef Mixture: Spread half of the cooked ground beef mixture on top of the potatoes.
7. Add Cheese: Sprinkle 1 cup of shredded cheddar cheese over the beef before layering the next set of potatoes.
8. Repeat Layers: Add the remaining potato slices, then the rest of the ground beef mixture. Pour the soup mixture over the top, covering everything evenly.
9. Top with Cheese: Finish by sprinkling the remaining cup of cheddar cheese on top.
10. Bake: Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. Remove the foil and bake for an additional 15 minutes until the cheese is bubbly and the potatoes are tender.
11. Garnish: Once out of the oven, let the casserole rest for a few minutes before serving. Garnish with fresh parsley if desired.
