Step-by-Step Instructions

1. Preheat the oven
   Preheat your oven to 375°F (190°C) to ensure even baking.
2. Cook beef and onions
   In a skillet over medium heat, brown the ground beef with chopped onion. Season with salt, pepper, and paprika. Cook until the beef is fully browned and onions are softened. Drain excess fat.
3. Prepare the sauce
   In a mixing bowl, combine cream of mushroom soup, milk (or heavy cream), and sour cream. Stir until smooth and fully blended.
4. Layer the beef
   Spread the cooked beef mixture evenly in the bottom of a greased 9×13-inch baking dish.
5. Add the potatoes
   Arrange the thinly sliced potatoes evenly over the beef layer. Keep slices uniform for even cooking.
6. Pour the sauce
   Pour the creamy mushroom mixture over the potatoes. Use a spatula to spread it evenly so all slices are covered.
7. Add cheese topping
   Sprinkle shredded cheddar cheese evenly over the entire surface.
8. Cover and bake
   Cover the dish with aluminum foil and bake for 45 minutes. This allows the potatoes to soften and absorb flavor.
9. Uncover and finish baking
   Remove the foil and bake for an additional 15 minutes, until the cheese is golden brown and bubbling.
10. Rest and garnish
    Let the casserole rest for 5 to 10 minutes before serving. Garnish with fresh parsley.
