How to make Creamy One-Pot Beef and Potato Casserole

Making this casserole is simple and fun! Follow the straightforward steps below to create a tasty and comforting meal.

Ingredients

1 lb ground beef
1 small onion, chopped
1 tsp salt
1/2 tsp black pepper
1/2 tsp paprika
2 cups thinly sliced russet or Yukon gold potatoes
1 can (10.5 oz) cream of mushroom soup
1/2 cup whole milk or heavy cream
1/2 cup sour cream (optional for extra creaminess)
1 1/2 cups shredded cheddar cheese
Fresh parsley, for garnish

Directions

Preheat the Oven
Start by preheating your oven to 375°F (190°C). This way, it’ll be hot and ready when it’s time to bake the casserole.
Cook the Beef and Onion
In a skillet over medium heat, add the ground beef and chopped onion. Cook until the beef is browned, stirring occasionally. Season with salt, black pepper, and paprika. Once cooked, drain any excess fat from the skillet to keep your casserole from being greasy.
Mix the Creamy Sauce
In a separate bowl, combine the cream of mushroom soup, milk (or heavy cream), and sour cream. Stir them together until the mixture is smooth and well blended.
Layer the Ingredients
In a greased 9×13-inch baking dish, spread the seasoned ground beef mixture evenly along the bottom. Then, layer the thinly sliced potatoes over the beef, making sure they’re arranged evenly.
Add the Creamy Mixture
Pour the creamy mushroom mixture over the potatoes. Use a spatula to spread it evenly across the top, ensuring all potato slices are well-covered.
Top with Cheese
Sprinkle shredded cheddar cheese evenly over the entire casserole. This will create a nice cheesy crust as it bakes.
Bake the Casserole
Cover the baking dish with aluminum foil and place it in the oven. Bake for 45 minutes. This allows the potatoes to cook and the flavors to meld together.
Finish Baking
After 45 minutes, carefully remove the foil and continue to bake for an additional 15 minutes. This step helps the cheese on top to become golden brown and bubbly.
Let It Rest
Once out of the oven, let the casserole rest for 5 to 10 minutes. This will help it set a bit, making it easier to serve. Before serving, garnish with fresh parsley for a pop of color.

Nutritional Benefits

This Creamy One-Pot Beef and Potato Casserole is not only tasty but also provides essential nutrients. The ground beef offers a good source of protein, which is crucial for energy and muscle growth.

If you choose to add sour cream, it can increase the creaminess and also provide probiotics, promoting gut health. Overall, this dish is a filling meal that gives you a variety of nutrients to keep you energized and healthy.
