Cheesy Ground Beef and Potato Casserole (Easy Family Dinner)

This Cheesy Ground Beef and Potato Casserole is a comforting, oven-baked dinner made with layers of tender potatoes, seasoned ground beef, a creamy garlic sauce, and plenty of melted cheddar cheese. It's the kind of hearty family meal that makes the kitchen smell wonderful and doesn't require expensive ingredients or complicated preparation.

Think of it as a cross between a classic hamburger potato casserole and cheesy scalloped potatoes. The potatoes soak up the savoury flavours of the beef and sauce as they bake, while the cheese forms a golden, bubbling topping.

It's especially handy when you have a packet of ground beef, a few potatoes, and some everyday pantry staples but aren't sure what to cook. Everything comes together in one baking dish, making it a practical option for busy weeknights, colder evenings, or feeding a hungry family on a budget.

Prep time: 20 minutes | Cook time: 65–75 minutes | Servings: 6

Ingredients

• 1 lb (450 g) lean ground beef
• 2 lb (900 g) potatoes, peeled and thinly sliced
• 1 medium onion, finely diced
• 3 garlic cloves, minced
• 1 tablespoon olive oil
• 2 tablespoons all-purpose flour
• 1 cup beef broth
• ¾ cup milk
• ½ cup sour cream
• 2 cups shredded sharp cheddar cheese, divided
• 1 tablespoon Worcestershire sauce
• 1 teaspoon smoked paprika
• 1 teaspoon dried thyme
• ½ teaspoon onion powder
• ½ teaspoon salt, or to taste
• ½ teaspoon black pepper
• 2 tablespoons chopped fresh parsley, optional

How to Make Cheesy Ground Beef and Potato Casserole

Step 1: Prepare the potatoes

Preheat your oven to 375°F (190°C). Lightly grease a 9 × 13-inch baking dish.

Peel the potatoes and slice them into thin, even rounds, approximately ⅛ inch thick. A mandoline slicer makes this easier, but a sharp knife works just as well.

Keep the slices roughly the same thickness so they cook evenly.

Step 2: Brown the ground beef

Heat the olive oil in a large skillet over medium-high heat. Add the diced onion and cook for 3–4 minutes until softened.

Add the ground beef, breaking it apart with a wooden spoon. Cook for 6–8 minutes until browned and no longer pink. Drain away any excess grease.

Stir in the garlic, Worcestershire sauce, smoked paprika, dried thyme, onion powder, salt, and black pepper. Cook for another minute until fragrant.

Step 3: Make the creamy sauce

Sprinkle the flour over the beef mixture and stir for about 1 minute.

Slowly pour in the beef broth, stirring continuously to prevent lumps. Add the milk and bring everything to a gentle simmer.

Cook for 3–4 minutes until the sauce begins to thicken. Remove the skillet from the heat and stir in the sour cream until smooth.

The sauce should remain slightly loose because the potatoes will absorb some of the liquid during baking.

Step 4: Layer the casserole

Arrange half of the sliced potatoes in the bottom of the prepared baking dish, overlapping them slightly.

Spoon half of the creamy ground beef mixture over the potatoes, spreading it evenly. Sprinkle with ½ cup of shredded cheddar cheese.

Repeat with the remaining potatoes and beef mixture. Reserve the remaining 1 cup of cheddar for the final topping.

Step 5: Bake until tender

Cover the baking dish tightly with aluminium foil and bake for 50–60 minutes, or until the potatoes are nearly fork-tender.

Remove the foil, sprinkle the remaining cheddar cheese over the casserole, and return it to the oven uncovered.

Bake for another 15 minutes, until the cheese is melted and golden and a knife slides easily through the potatoes.

Step 6: Rest and serve

Allow the casserole to rest for 10 minutes before serving. This gives the creamy sauce time to settle and makes it easier to scoop out portions.

Finish with chopped fresh parsley and serve warm.

Tips for the Best Beef and Potato Casserole

Slice the potatoes thinly. Thick potato slices can remain firm even after a long baking time. Aim for approximately ⅛ inch so they become tender and absorb the creamy sauce.

Choose a good melting cheese. Sharp cheddar gives the casserole a stronger flavour, but you can combine cheddar with Monterey Jack or mozzarella for an extra gooey topping.

Keep the dish covered during the first stage of baking. The foil traps steam, helping the potatoes soften without drying out the beef mixture.

Check the centre before serving. Insert a knife into the middle of the casserole. If the potatoes still feel firm, cover the dish and bake for another 10–15 minutes.

Easy Variations Using What You Have

This casserole is easy to adapt depending on what's already in your fridge.

• Add vegetables: Stir frozen peas, sweetcorn, or finely diced carrots into the beef mixture.
• Make it spicy: Add chopped jalapeños, chilli flakes, or a pinch of cayenne pepper.
• Try a different meat: Ground turkey works well as a lighter alternative.
• Use leftover potatoes: Thinly sliced cooked potatoes can shorten the baking time. Check for tenderness earlier.
• Make it extra creamy: Replace ¼ cup of the milk with additional sour cream or a little cream cheese.

What to Serve with Ground Beef and Potato Casserole

Because this casserole already contains meat, potatoes, and cheese, you don't need much else to make it a complete meal.

A crisp green salad with a light vinaigrette helps balance the rich, creamy sauce. Steamed green beans, roasted broccoli, or sautéed cabbage also work beautifully.

For a more filling dinner, serve it with crusty bread or warm dinner rolls to soak up the extra sauce.

How to Store and Reheat Leftovers

Refrigerator: Allow the casserole to cool, then transfer leftovers to an airtight container. Refrigerate promptly and keep for up to 3–4 days.

Freezer: Divide the cooled casserole into individual portions and freeze in airtight containers for up to 2–3 months for best quality. The potatoes may become slightly softer after thawing.

Reheating: Cover with foil and warm in a 350°F (175°C) oven until piping hot throughout, or microwave individual portions until thoroughly heated.

For additional guidance on storing cooked meals safely, see the USDA's leftovers and food safety advice.

Can You Prepare This Casserole Ahead of Time?

Yes! You can cook the ground beef mixture a day ahead and refrigerate it in a covered container.

When you're ready to bake, slice the potatoes fresh, assemble the layers, and follow the recipe instructions. You may need a little extra baking time if the beef mixture is cold.

For food safety, ground beef should reach an internal temperature of 160°F (71°C) when cooked. You can check the recommended temperature using the FoodSafety.gov safe minimum cooking temperature chart.

Frequently Asked Questions

Do I need to boil the potatoes first?

No. Thinly sliced raw potatoes cook directly in the creamy sauce while the casserole bakes. Just make sure the baking dish is tightly covered during the first stage.

Can I make this casserole without sour cream?

Yes. Plain Greek yoghurt can be substituted, although it may give the sauce a slightly tangier flavour. Alternatively, use a little extra milk and cream cheese.

Why are my potatoes still hard?

The slices may be too thick, or the casserole may need more time in the oven. Cover it again with foil and continue baking until the centre is completely tender.

Can I use frozen ground beef?

Yes, but thaw it safely before cooking. Brown the beef thoroughly in the skillet before adding it to the casserole.
