Beef Potato Casserole

There are casseroles that are good, and then there are casseroles that become family legends. This Beef Potato Casserole is absolutely the latter. It’s a hearty, comforting, and incredibly satisfying dish that layers tender potatoes, seasoned ground beef, and a creamy, cheesy sauce into one bubbling, golden masterpiece. It’s the kind of meal that makes everyone at the table go quiet for a moment—then reach for seconds.

What I love most about this casserole is how it combines humble ingredients into something that feels both rustic and special. The potatoes become perfectly tender, the beef is seasoned to perfection, and the creamy sauce ties everything together with a blanket of melted cheese. It’s the ultimate comfort food, perfect for busy weeknights, potlucks, or a cozy Sunday dinner.

Ingredients

For the Casserole:

2 pounds russet potatoes, peeled and thinly sliced (about ⅛-inch thick)
1½ pounds ground beef
1 medium yellow onion, finely chopped
2 cloves garlic, minced
1 teaspoon salt (or to taste)
½ teaspoon black pepper
1 teaspoon smoked paprika (or regular paprika)

For the Creamy Sauce:

1 can (10.5 oz) cream of mushroom soup
½ cup sour cream
½ cup milk
½ teaspoon garlic powder
½ teaspoon onion powder

For the Topping:

1½ cups shredded cheddar cheese
Fresh parsley or chives for garnish (optional)

Directions

Preheat and prepare: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with nonstick spray or butter.
Cook the beef: In a large skillet over medium heat, cook the ground beef and onion together, breaking the meat up with a spatula, until the beef is browned and the onion is soft, about 8-10 minutes. Add the garlic and cook for another minute until fragrant. Drain off any excess grease. Season with salt, pepper, and paprika.
Make the sauce: In a medium bowl, whisk together the cream of mushroom soup, sour cream, milk, garlic powder, and onion powder until smooth and well combined.
Layer the casserole: Arrange half of the sliced potatoes in an even layer in the prepared baking dish. Top with half of the seasoned beef mixture. Pour half of the sauce over the top. Repeat with the remaining potatoes, beef, and sauce.
Add the cheese: Sprinkle the shredded cheddar cheese evenly over the top.
Cover and bake: Cover the dish tightly with aluminum foil and bake for 45 minutes. Remove the foil and bake for another 15-20 minutes, until the potatoes are tender and the cheese is bubbly and golden.
Rest and serve: Let the casserole rest for 10 minutes before serving. Garnish with fresh parsley or chives if desired.

Variations

Cheesy Ranch: Substitute the cream of mushroom soup with cream of chicken soup and add 1 packet of ranch dressing mix to the sauce.
Mexican Twist: Add 1 can of diced green chiles to the beef mixture and use pepper jack cheese instead of cheddar. Top with crushed tortilla chips for a crunchy finish.
Loaded Baked Potato: Stir cooked, crumbled bacon into the beef mixture and top with green onions before serving.
Mushroom Lover: Sauté 2 cups of sliced mushrooms with the onion and add them to the beef mixture.
Vegetable Boost: Layer in sliced carrots, bell peppers, or frozen peas and corn for extra color and nutrition.
Gluten-Free: Use a gluten-free cream of mushroom soup and ensure all other ingredients are gluten-free.

Expert Tips

Slice potatoes evenly: Thin, uniform slices are key to even cooking. Use a mandoline or a sharp knife for consistent thickness.
Don’t skip the resting time:Letting the casserole rest allows the sauce to thicken and makes serving cleaner and easier.
Season in layers: Season each layer of potatoes with a pinch of salt and pepper to ensure even flavor throughout.
Cover tightly: The foil is essential for trapping steam and cooking the potatoes through. A loose cover can lead to undercooked potatoes.
Check for doneness: Pierce the potatoes with a fork to ensure they’re tender before removing the foil for the final browning.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or in a 350°F oven until warmed through. The casserole also freezes beautifully for up to 2 months—thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Can I use a different type of potato? Yes. Yukon Gold or red potatoes hold their shape well. Russets are classic for their starchy, creamy texture.
Do I need to peel the potatoes?That’s up to you. Leaving the skins on adds texture and nutrients, but peeled potatoes give a more classic, creamy result.
Can I use ground turkey instead of beef? Yes. Ground turkey or chicken work well in this recipe. Just adjust seasoning as needed.
Can I make this ahead of time?Yes. Assemble the casserole (without baking), cover, and refrigerate for up to 24 hours. When ready, bake as directed, adding 10-15 minutes to the bake time.
Why is my casserole watery? This can happen if the potatoes release too much moisture. Make sure to slice them thinly and pat them dry before layering. You can also let the casserole rest longer after baking.

What to Serve With This Dish
