Ingredients for Cheesy Beef and Potato Casserole
For the Casserole
- 1 pound ground beef
- 4 cups potatoes, peeled and thinly sliced
- 1 medium onion, chopped
- 2 cups shredded cheddar cheese
- 1 can (10.5 ounces) cream of mushroom soup
- 1/2 cup milk
- 1 teaspoon garlic powder
- 1 teaspoon paprika
- Salt and pepper, to taste
For the Topping
- 1 cup crushed cornflakes or breadcrumbs
- 2 tablespoons butter, melted
A Closer Look at the Ingredients
Ground Beef
Ground beef gives the casserole its hearty, savory base. Choose good-quality beef for the best flavor. If you want a lighter option, lean ground turkey or chicken can be used.
Potatoes
Four cups of peeled, thinly sliced potatoes form the body of the casserole. Fresh potatoes give the best flavor. Slicing them thinly is important, because they cook in the oven rather than ahead of time, and thin slices become tender without falling apart.
Onion
A chopped onion cooks right along with the beef, and it adds sweetness and savory depth.
Cheddar Cheese
Two cups of shredded cheddar make the casserole cheesy. Half goes in each layer.
Cream of Mushroom Soup and Milk
The soup and milk are stirred together into a smooth sauce that is poured over the layers. The sauce keeps the potatoes moist as they bake and ties everything together. If you prefer a gluten-free option, you can use a gluten-free cream of mushroom soup.
Garlic Powder and Paprika
These two seasonings go into the beef mixture and add savory and slightly smoky flavor.
Salt and Pepper
Season to taste, but be careful with the salt, since the soup and cheese are already salty.
Crushed Cornflakes or Breadcrumbs
The topping adds crunch. Cornflakes give a light, crisp texture, and breadcrumbs give a more traditional crumb topping.
Melted Butter
Butter coats the crumbs so they brown and crisp in the oven.
How to Make Cheesy Beef and Potato Casserole
Step 1: Preheat the Oven
Preheat the oven to 350°F (175°C). This helps the casserole cook evenly from the start.
Step 2: Brown the Beef and Onion
In a large skillet over medium heat, add the ground beef and chopped onion. Cook until the beef is browned and the onion is translucent, about 5 to 7 minutes. Drain any excess grease.
Draining the fat keeps the casserole from turning greasy.
Step 3: Season the Beef
Stir in the garlic powder, paprika, salt, and pepper. Mix well.
Seasoning the beef directly builds flavor in the layers.
Step 4: Make the Sauce
In a large bowl, combine the cream of mushroom soup and milk. Stir until smooth.
Step 5: Layer the Casserole
In a greased 9×13-inch baking dish, layer half of the sliced potatoes across the bottom. Sprinkle half of the beef mixture over the potatoes, then half of the cheese. Repeat the layers.
Step 6: Add the Sauce
Pour the soup mixture evenly over the layered ingredients.
Step 7: Add the Topping
Combine the crushed cornflakes or breadcrumbs with the melted butter. Spread the mixture evenly over the top of the casserole.
Step 8: Bake
Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. Remove the foil and bake for another 15 to 20 minutes, until the potatoes are tender and the top is golden brown.
Step 9: Cool and Serve
Let the casserole cool for a few minutes before serving. This helps the layers set and makes it easier to serve.

Why This Recipe Works
Layering spreads flavor. Putting seasoned beef and cheese between two layers of potatoes means every bite has all three.
The sauce keeps everything moist. Cream of mushroom soup thinned with milk pours easily into the layers and keeps the potatoes from drying out.
Thin slices cook evenly. Thinly sliced potatoes become tender in the time it takes the casserole to bake.
Covering, then uncovering. The foil traps steam so the potatoes soften, and removing it browns the top.
A buttery topping adds contrast. The crisp crumbs are a counterpoint to the creamy layers.
A short rest helps the layers set. Cooling for a few minutes makes serving much easier.
Tips for the Best Casserole
- Slice the potatoes thinly. This helps them become tender without falling apart.
- Drain the beef well. Excess grease can make the casserole heavy.
- Be careful with salt. The soup and cheese can already be salty. Taste as you go.
- Stir the sauce until smooth. This helps it pour evenly.
- Distribute the layers evenly. Each layer should reach the corners of the dish.
- Spread the topping evenly. It should cover the casserole for a golden finish.
- Bake until the potatoes are tender. The covered time cooks them, and the uncovered time browns the top.
- Let it rest. A few minutes of cooling helps the layers hold together.
- Check the potatoes before serving. The potatoes should be easy to pierce with a fork. This check is my own suggestion rather than part of the original recipe.
Variations
Vegetable Version
Add layers of steamed broccoli, carrots, or bell peppers for extra nutrition and color.
Spicy Twist
Mix in jalapeños or a dash of hot sauce for some heat.
Different Cheeses
Try Monterey Jack, Gouda, or a spicy pepper jack in place of cheddar.
Lighter Version
Use lean ground turkey or chicken in place of ground beef.
Gluten-Free Option
Use a gluten-free cream of mushroom soup. The cornflakes or breadcrumbs in the topping contain gluten unless they are labeled gluten-free, so check the packaging if this matters to you.
What to Serve with Beef and Potato Casserole
This casserole is rich and filling, so simple sides work best.
- A side salad. Fresh greens balance the creamy layers.
- Steamed vegetables. Green beans or broccoli add color.
- Toppings. A dollop of sour cream or a sprinkle of parsley or chives adds a finishing touch.
- Drinks. A crisp white wine or iced tea.
Make-Ahead, Storage, and Freezing
Make Ahead
Assemble the casserole a day in advance, cover it well, and refrigerate. Bake it straight from the refrigerator, adding a few extra minutes to the cooking time.
Storing Leftovers
Store leftovers in an airtight container in the refrigerator for up to 3 days.
Freezing
Freeze leftovers for up to 2 months.
Reheating
Reheat in the oven or microwave until hot throughout.
Understanding the Method
Why Brown the Beef and Onion Together?
Cooking the onion with the beef lets it soften in the beef’s drippings, so it adds flavor to the meat. The onion is done when it turns translucent, which usually happens at about the same time the beef finishes browning.
Why Drain the Grease?
Ground beef releases fat as it cooks. If you leave it in, it ends up in the casserole and can make the sauce greasy. Draining it keeps the layers and the sauce cleaner.
Why Season the Beef Directly?
Garlic powder and paprika blend into the warm meat better than they would if sprinkled between the layers. The potatoes, which are otherwise unseasoned, get their flavor from the beef and the sauce.
Why Mix the Soup with Milk?
Condensed soup straight from the can is thick. Stirring in milk loosens it so it pours and spreads through the layers, instead of sitting in a clump on top.
Why Bake Covered First?
Foil traps steam, which helps the raw potato slices soften evenly. Without the cover, the top could brown long before the potatoes cook.
A Note on the Topping
In this recipe, the crumb topping goes on before the dish is covered. That means the crumbs steam under the foil for the first 30 minutes, then crisp up when the foil comes off. The source does not mention any other order. If you would rather keep the crumbs crisp the whole time, you could try adding them when you remove the foil, but I have not tested that change.
Layering Guide
Building the casserole in a clear order makes the difference between a neat, evenly cooked dish and a lopsided one.
- Grease the dish. Use butter or nonstick spray in the 9×13-inch baking dish.
- First potato layer. Spread half of the sliced potatoes across the bottom. Overlap them slightly so there are no large gaps.
- First beef layer. Sprinkle half of the seasoned beef and onion over the potatoes.
- First cheese layer. Add half of the shredded cheddar.
- Repeat. Add the remaining potatoes, beef, and cheese in the same order.
- Pour the sauce. Spread the soup and milk mixture evenly so it reaches the corners and edges.
- Add the topping. Spread the buttered crumbs in an even layer.
Each layer should be relatively even, so that the slices cook at the same rate and every portion has the same balance of potato, beef, and cheese.
Preparing the Potatoes
- Peel first. The recipe calls for peeled potatoes.
- Slice thinly and evenly. Uniform slices cook at the same pace. A sharp knife works, and a mandoline would give very even slices, though the original recipe does not call for one.
- Measure by volume. The recipe needs 4 cups of sliced potatoes. This is an approximate amount, so a little more or less will not harm the dish.
- Slice just before assembling. Cut potatoes can darken when they sit out. This is a general kitchen tip of mine and is not part of the original recipe.
Planning the Meal
The total time is about an hour from start to finish, including prep and baking.
- Use the oven time. While the casserole bakes, you can prepare a salad or steam a vegetable.
- Serve it from the dish. Cut into squares and lift out with a wide spatula.
- Cook for a crowd. If you need to feed more people, you could make a second casserole in another dish. I have not tested doubling the recipe in a single larger pan.
- Plan for leftovers. The casserole keeps for up to 3 days in the refrigerator, which makes it good for lunches.
A Closer Look at the Cheese
Two cups of shredded cheddar is a generous amount, and it is divided between the two layers. Cheddar gives a sharp, tangy flavor that stands up to the beef and the creamy sauce. Shredding your own cheese from a block can give a smoother melt than pre-shredded cheese, which is sometimes coated to prevent clumping. This is a general tip of mine, not part of the original recipe.
If you want to change the flavor, you can try Monterey Jack, Gouda, or a spicy pepper jack in place of the cheddar.
Troubleshooting Guide
The potatoes are still firm
The slices may have been too thick, or the casserole may need more time. Bake a little longer, uncovered or covered as needed, and slice thinner next time.
The casserole is greasy
The beef may not have been drained well. Drain thoroughly before layering.
The casserole is too salty
Soup and cheese both contain salt. Go easy on added salt and taste the beef mixture before layering.
The topping is soggy
The topping steams under foil. It crisps once the foil is removed, so make sure to bake the full uncovered time until golden brown.
The layers fall apart when served
Let the casserole rest for a few minutes after baking so the layers can set.
The sauce is lumpy
Stir the soup and milk until smooth before pouring.
The top is browning too fast
Cover the dish loosely with foil for the rest of the bake.
