Ingredients

• 1 pound ground beef: Provides a savory, hearty base for the casserole.
• 2 pounds potatoes: Thinly sliced potatoes become tender and absorb the flavors of the sauce.
• 1 medium yellow onion: Adds sweetness and depth to the beef mixture.
• 1 can condensed cream of mushroom soup (10.5 ounces): Creates a creamy sauce that helps keep the casserole moist.
• 1 cup beef broth: Adds moisture and enhances the savory flavor.
• 2 cups shredded cheddar cheese: Creates a rich, cheesy topping.
• 1 teaspoon garlic powder: Adds a little extra flavor.
• Salt and black pepper, to taste: Season the beef and potatoes.

How to Make Oven Baked Cheesy Beef and Potato Casserole

Step 1: Prepare the Oven

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

Wash, peel if desired, and thinly slice the potatoes into rounds about 1/8 to 1/4 inch thick. Keeping the slices similar in size helps them cook evenly.

Step 2: Brown the Ground Beef

Heat a large skillet over medium heat. Add the ground beef and diced onion, breaking the meat into small pieces as it cooks.

Cook for about 7–10 minutes, until the beef is browned and no longer pink. Ground beef should reach an internal temperature of 160°F (71°C). Drain excess grease, then season with garlic powder, salt, and black pepper.

Step 3: Prepare the Creamy Sauce

In a medium bowl, whisk together the condensed cream of mushroom soup and beef broth until smooth.

The mixture should be pourable enough to spread throughout the casserole. This sauce helps the potatoes soften while adding a rich, savory flavor.

Step 4: Assemble the Casserole

Arrange half of the sliced potatoes in an even layer in the prepared baking dish. Spread half of the beef mixture over the potatoes, then spoon some of the sauce over the top.

Repeat with the remaining potatoes and beef. Pour the rest of the sauce evenly over the casserole, making sure the potatoes are well coated.

Step 5: Cover and Bake

Cover the baking dish tightly with aluminum foil and bake for 50–60 minutes.

Carefully remove the foil and check the potatoes with a fork. They should be nearly tender. If they are still firm, cover the dish and continue baking for another 10–15 minutes.

Step 6: Add the Cheese

Sprinkle the shredded cheddar evenly over the top. Return the casserole to the oven uncovered and bake for another 10–15 minutes, until the potatoes are tender and the cheese is melted and lightly golden.

Let the casserole rest for 10 minutes before serving. This allows the sauce to settle and makes the portions easier to serve.

Tips for the Best Cheesy Beef and Potato Casserole

• Slice the potatoes thinly: Thick slices take longer to cook and may remain firm in the center.
• Cover the dish tightly: Trapping steam helps the potatoes cook evenly.
• Drain excess grease: This keeps the sauce from becoming oily.
• Check the potatoes before adding cheese: If they need more time, continue baking before adding the topping.
• Shred your own cheese: Freshly shredded cheddar often melts more smoothly than pre-shredded cheese.
• Allow time to rest: A short resting period helps the creamy sauce thicken slightly.

Easy Variations

You can easily customize this casserole to match your family’s preferences.

• Extra cheesy: Combine cheddar with Monterey Jack or mozzarella.
• Add vegetables: Include sliced mushrooms, diced bell peppers, or frozen peas.
• Smoky flavor: Sprinkle cooked, crumbled bacon over the cheese topping.
• Spicy version: Add a pinch of cayenne pepper or red pepper flakes to the beef.
• Different soup: Use condensed cream of chicken soup instead of mushroom soup for a milder flavor.

These optional additions will change the ingredient list.

What to Serve with Cheesy Beef and Potato Casserole

This casserole is filling enough to serve as a complete main course. For a balanced meal, pair it with steamed green beans, roasted broccoli, glazed carrots, or a crisp garden salad.

Warm dinner rolls or garlic bread are also excellent choices for soaking up the creamy sauce. If you’re serving a larger family dinner, add a simple vegetable side to complement the rich beef and cheese.

Storage and Reheating

Allow leftovers to cool, then store them in an airtight container in the refrigerator for up to 3–4 days.

To reheat individual portions, microwave until steaming hot. For larger portions, place the casserole in an oven-safe dish, cover with foil, and warm at 325°F (165°C) until heated through. Add a small splash of broth if the sauce has thickened too much.

You can freeze portions in freezer-safe containers for up to 2–3 months for best quality. Thaw overnight in the refrigerator before reheating. The potatoes may soften slightly after freezing, but the casserole will still be delicious.

Frequently Asked Questions

Do I need to cook the potatoes before baking?

No. Thinly sliced raw potatoes cook in the creamy sauce while the casserole bakes. Covering the dish helps trap steam and soften the potatoes.

Why are my potatoes still hard?

The slices may be too thick, or the dish may need more baking time. Cover the casserole again and continue baking until a fork slides easily into the potatoes.

Can I prepare this casserole ahead of time?

Yes. Brown the beef and onion, prepare the sauce, and slice the potatoes before assembling. For the best texture, assemble shortly before baking because raw potato slices can discolor when exposed to air.

Can I use ground turkey instead of beef?

Yes. Ground turkey works as a substitute. Cook it thoroughly to an internal temperature of 165°F (74°C), and consider adding extra seasoning to enhance the flavor.
