Step-by-Step Instructions

1. Preheat the oven
   Set oven to 375°F (190°C) so it is fully heated before baking.
2. Cook beef and onions
   In a skillet over medium heat, brown ground beef with chopped onion. Season with salt, pepper, and paprika. Drain excess fat to avoid a greasy casserole.
3. Prepare creamy sauce
   In a bowl, mix cream of mushroom soup, milk (or heavy cream), and sour cream until smooth and fully combined.
4. Layer the beef
   Spread cooked beef mixture evenly in the bottom of a greased 9×13-inch baking dish.
5. Add potato layer
   Arrange thinly sliced potatoes evenly over the beef, ensuring full coverage for even cooking.
6. Pour sauce
   Spread creamy mushroom mixture over the potatoes, making sure all slices are fully coated.
7. Add cheese topping
   Sprinkle shredded cheddar evenly over the top layer.
8. Cover and bake
   Cover with foil and bake for 45 minutes to allow potatoes to soften and flavors to blend.
9. Uncover and finish baking
   Remove foil and bake for another 15 minutes until cheese is melted, golden, and bubbling.
10. Rest and serve
    Let casserole rest for 5–10 minutes before serving. Garnish with fresh parsley.
