This Ground Beef and Potatoes Casserole is a classic comfort dish that brings together hearty ground beef, tender potatoes, and a creamy sauce all baked to golden perfection. It’s simple but full of warm, homey flavors that feel just right on any cozy night.
I love making this casserole when I want an easy dinner that the whole family will enjoy. One of my favorite things is how the flavors meld together while baking, and the potatoes get soft but still hold their shape. It’s one of those dishes where you can throw everything in one pan and let it do its thing, which makes dinner feel so relaxed and fuss-free.
When I serve it, I like to add a simple green salad or some steamed veggies on the side to balance the richness. It’s the kind of meal that keeps well too, so I often have plenty left over to eat the next day. If you need a comforting meal that’s easy to prepare and satisfying, this casserole is a great go-to option.
Key Ingredients & Substitutions
Ground Beef: I like using 80/20 ground beef because it’s juicy and flavorful. If you want a leaner option, try 90% lean beef or even ground turkey for a lighter dish.
Potatoes: Yukon Gold potatoes work best here—they hold their shape and get tender without falling apart. Russets are okay but can get mushy. Thin slicing helps them cook through evenly.
Cream of Mushroom Soup: This gives the casserole creamy texture and flavor. If you don’t have it, cream of chicken or a homemade white sauce works fine. For dairy-free, try a coconut milk–based sauce.
Cheese: Cheddar is my go-to because it melts well and adds sharpness. You can mix in mozzarella or Monterey Jack for a milder taste or use a dairy-free cheese if needed.
How Can You Make Sure the Potatoes Cook Well in the Casserole?
Potatoes need enough moisture and proper slicing to cook evenly inside the casserole. Here’s how I handle it:
- Slice potatoes thinly (about 1/8 inch). This helps them cook through while baking.
- Layer potatoes with the creamy soup mixture to keep them moist and tender.
- Cover the casserole with foil during most of the baking to trap steam and cook potatoes gently.
- Remove foil near the end to brown the cheese and slightly crisp the top.
If you follow these steps, your potatoes will be soft without turning into mush, blending perfectly with the beef and cheese layers.
Equipment You’ll Need
- 9×13 inch casserole dish – perfect size for layering and baking everything evenly.
- Large skillet – you’ll brown the ground beef and sauté the onions in this.
- Sharp knife and cutting board – for slicing potatoes thinly and chopping onions.
- Mixing bowl – to combine the creamy soup mixture smoothly.
- Aluminum foil – keeps the casserole moist while baking.
- Spatula or wooden spoon – for stirring the beef and spreading layers evenly.
Flavor Variations & Add-Ins
- Swap ground beef with ground turkey or chicken for a leaner casserole that still tastes great.
- Add diced bell peppers or mushrooms to the beef mixture for extra veggies and flavor.
- Use pepper jack or a blend of cheeses to add a little spice or different texture.
- Stir in some cooked bacon bits for a smoky touch that pairs well with potatoes and cheese.
Ground Beef and Potatoes Casserole
Ingredients You’ll Need:
- 1 lb (450g) ground beef
- 4 cups thinly sliced potatoes (about 4 medium potatoes)
- 1 small onion, finely chopped
- 2 cups shredded cheddar cheese
- 1 can (10.5 oz) cream of mushroom soup (or cream of chicken)
- 1 cup sour cream
- 1/2 cup milk
- 2 cloves garlic, minced
- 1 tsp salt
- 1/2 tsp black pepper
- 1/2 tsp paprika (optional)
- 2 tbsp olive oil or butter
- Fresh parsley or chives for garnish
How Much Time Will You Need?
This recipe takes about 15 minutes of prep time and roughly 1 hour of baking. You’ll spend some time slicing the potatoes and cooking the beef mixture, followed by layering and baking. The casserole also needs to rest about 5-10 minutes before serving. It’s a perfect dinner that comes together in under two hours with plenty of hands-off baking time.
Step-by-Step Instructions:
1. Prepare the Oven and Cook the Beef:
Start by preheating your oven to 350°F (175°C) and lightly grease a 9×13 inch casserole dish. Next, heat olive oil or butter in a large skillet over medium heat. Add the chopped onion and minced garlic, sautéing until soft and fragrant. Then, add the ground beef, cooking and breaking it apart until browned. Season with salt, pepper, and paprika. Drain excess fat if needed.
2. Mix the Creamy Sauce and Layer Ingredients:
In a mixing bowl, combine the cream of mushroom soup, sour cream, and milk. Stir well until smooth. Spread half of the sliced potatoes evenly in the casserole dish. Layer the cooked ground beef over the potatoes, then pour half of the creamy soup mixture on top. Add the remaining sliced potatoes in a second layer, and top with the rest of the soup mixture, spreading gently to cover.
3. Add Cheese and Bake:
Sprinkle the shredded cheddar cheese evenly over the entire casserole. Cover the dish with aluminum foil and bake for 45 minutes. Remove the foil and bake for an additional 15-20 minutes until the cheese is bubbly and golden, and the potatoes are tender when pierced with a fork. Let the casserole rest for 5-10 minutes before serving. Garnish with fresh parsley or chives to add a burst of color and fresh flavor.
Can I Use Frozen Potatoes for This Casserole?
Yes, you can use frozen sliced potatoes, but be sure to thaw and drain them well before layering to avoid excess moisture. This helps keep the casserole from becoming watery and ensures the potatoes cook evenly.
How Can I Make This Recipe Ahead of Time?
You can assemble the casserole the night before, cover it tightly with foil or plastic wrap, and refrigerate. Bake it the next day as directed, adding a few extra minutes to the baking time since it will be cold going into the oven.
What’s the Best Way to Store Leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through. Adding a splash of milk can help restore creaminess if the casserole seems dry after reheating.
Can I Substitute the Cream of Mushroom Soup?
Absolutely! Cream of chicken soup works great as a substitute. For a homemade alternative, you can make a simple white sauce with butter, flour, milk, and seasonings to keep it creamy and delicious.
