How to Make Ground Beef Potato Casserole

Step 1: Prepare the Potatoes

Preheat your oven to 375°F (190°C).

Wash and peel the potatoes if desired. Slice them thinly, about 1/8 to 1/4 inch thick.

Try to keep the slices relatively uniform so they cook evenly.

Set the sliced potatoes aside while you prepare the beef mixture.

Step 2: Brown the Ground Beef

Heat a large skillet over medium-high heat and add the olive oil.

Add the ground beef and diced onion. Cook for about 6–8 minutes, breaking the beef apart with a wooden spoon as it cooks.

Once the beef is browned and the onion has softened, add the minced garlic.

Cook for another 30–60 seconds.

Drain any excess grease if necessary.

Step 3: Season the Beef

Season the beef mixture with paprika, garlic powder, onion powder, oregano, salt, and black pepper.

Stir well so the seasonings are evenly distributed.

Taste and adjust the seasoning if needed.

Step 4: Make the Creamy Sauce

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

This creates a creamy sauce that helps keep the casserole moist while it bakes.

If you prefer a richer flavor, you can replace some of the milk with heavy cream or sour cream.

Step 5: Assemble the Casserole

Lightly grease a 9×13-inch baking dish.

Arrange a layer of sliced potatoes across the bottom of the dish.

Season the potatoes lightly with salt and pepper.

Spread about half of the cooked ground beef mixture over the potatoes.

Pour some of the creamy soup mixture over the beef and potatoes.

Repeat with another layer of potatoes, followed by the remaining beef and sauce.

Finish with the shredded cheddar and mozzarella cheese.

Make sure the cheese is spread evenly across the top.

Step 6: Cover and Bake

Cover the casserole tightly with aluminum foil.

Place it in the preheated oven and bake for approximately 45 minutes.

The foil traps steam inside the dish, helping the potatoes become tender.

Step 7: Remove the Foil and Finish Baking

After 45 minutes, carefully remove the foil.

Return the casserole to the oven and bake uncovered for another 15–20 minutes, or until the potatoes are completely tender and the cheese is melted, bubbly, and lightly golden.

For an extra golden top, you can broil the casserole for 1–2 minutes at the end. Watch it closely because the cheese can brown quickly.

Step 8: Rest Before Serving

Remove the casserole from the oven and let it rest for about 10 minutes before slicing.

This gives the creamy sauce time to settle and makes the casserole easier to serve.

Sprinkle fresh parsley or green onions over the top before serving.

Tips for the Best Ground Beef Potato Casserole

Slice the Potatoes Thinly

Thin, evenly sliced potatoes cook much more reliably than thick slices. If your potato slices are too thick, the casserole may need additional baking time.

Brown the Beef Well

Don’t just cook the beef until it is no longer pink. Allowing it to develop some browned edges gives the casserole a deeper, richer flavor.

Don’t Skip the Resting Time

Letting the casserole sit for 10 minutes after baking helps everything come together. It also prevents the sauce from running all over the plate when you cut into it.

Check the Potatoes

Before removing the casserole from the oven, insert a fork or knife into the center. The potatoes should be tender and easy to pierce.

Easy Variations

Add Vegetables

Add vegetables such as frozen peas, corn, carrots, mushrooms, or green beans for extra color and nutrition.

Make It Extra Cheesy

Use a combination of cheddar, mozzarella, Monterey Jack, or Colby cheese for an even cheesier casserole.

Add Bacon

Cooked, crumbled bacon adds a smoky, savory flavor that pairs wonderfully with the beef and potatoes.

Try Different Meat

Ground turkey, ground chicken, or sausage can replace the ground beef.

Add a Little Heat

For a spicy version, add diced jalapeños, crushed red pepper flakes, or a little hot sauce to the beef mixture.

What to Serve With Ground Beef Potato Casserole

Because this casserole is already hearty, simple side dishes work best.

Serve it with:

• Green salad
• Steamed broccoli
• Roasted green beans
• Glazed carrots
• Corn on the cob
• Dinner rolls
• Garlic bread
• Steamed vegetables

A crisp green salad is especially good because its freshness balances the creamy casserole.

How to Store Leftovers

Allow the casserole to cool before transferring leftovers to an airtight container.

Store in the refrigerator for up to 4 days.

To reheat, place an individual portion in the microwave until hot. For larger portions, cover with foil and warm in a 350°F (175°C) oven until heated through.

Can You Freeze Ground Beef Potato Casserole?

Yes, although the texture of the potatoes may become slightly softer after freezing.

For best results, let the casserole cool completely before transferring it to a freezer-safe container.

Freeze for up to 2–3 months.

Thaw overnight in the refrigerator and reheat in the oven until thoroughly hot.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes. Assemble the casserole, cover it tightly, and refrigerate it for up to about 24 hours before baking. You may need to add a little extra baking time if the casserole goes directly from the refrigerator into the oven.

Do I need to boil the potatoes first?

No. Thinly sliced potatoes can cook directly in the casserole. Covering the dish during the first part of baking helps create the steam needed to soften them.

What potatoes are best for this recipe?

Russet and Yukon Gold potatoes both work well. Yukon Gold potatoes have a naturally creamy texture, while russets become soft and tender as they bake.

Can I use pre-cooked potatoes?

Yes. If you’re using leftover cooked potatoes, reduce the baking time because they only need to heat through and allow the flavors to combine.

Why are my potatoes still hard?

The most common reason is that the slices are too thick or the casserole did not have enough moisture or baking time. Cover the dish tightly and continue baking until the potatoes are fork-tender.
