Step-by-Step Instructions

1. Preheat the Oven

Preheat your oven to 375°F (190°C) so it reaches the proper temperature before baking the casserole.

2. Cook the Beef and Onion

In a skillet over medium heat, cook the 1 lb ground beef with the 1 small chopped onion.

Season with:

• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/2 teaspoon paprika

Cook until the beef is fully browned and the onion is softened. Drain any excess fat to prevent the casserole from becoming greasy.

In a mixing bowl combine:

• 1 can (10.5 oz) cream of mushroom soup
• 1/2 cup whole milk or heavy cream
• 1/2 cup sour cream (optional)

Stir until the mixture becomes smooth and well blended.

4. Layer the Beef

Spread the cooked ground beef mixture evenly across the bottom of a greased 9×13-inch baking dish.

5. Add the Potato Layer

Arrange the 2 cups thinly sliced potatoes evenly over the ground beef layer.

Ensure the slices are spread out evenly so they cook properly.

6. Add the Creamy Sauce

Pour the creamy mushroom mixture over the potatoes.

Use a spatula to spread the sauce so it coats all of the potato slices evenly.

7. Add the Cheese Topping

Sprinkle 1 1/2 cups shredded cheddar cheese evenly across the top of the casserole.

8. Cover and Bake

Cover the baking dish with aluminum foil.

Bake for 45 minutes, allowing the potatoes to soften and absorb the creamy sauce.

9. Finish Baking

Remove the foil and continue baking for 15 additional minutes.

The cheese should become golden brown and bubbly.

10. Rest and Serve
