Ingredients

• 1½ pounds ground beef or ground turkey
• 1 medium onion, chopped
• 3 cloves garlic, minced
• 5–6 medium russet potatoes, thinly sliced, about ⅛ inch thick
• 2 cups shredded cheddar cheese, divided
• 1 cup shredded mozzarella cheese, optional
• 1 can (10.5 ounces) cream of mushroom soup, or cream of chicken soup
• 1 cup milk
• 1 teaspoon salt
• ½ teaspoon black pepper
• ½ teaspoon paprika, optional
• 1 tablespoon olive oil or butter, for greasing the dish

How to Make Cheesy Hamburger Potato Casserole

1. Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish with olive oil or butter.

2. Prepare the Potatoes

Wash and peel the russet potatoes if desired.

Slice them very thinly, about ⅛ inch thick. Keeping the slices similar in thickness helps them cook evenly.

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

3. Brown the Ground Beef

Heat a large skillet over medium-high heat.

Add the ground beef or turkey and cook for about 5–7 minutes, breaking it apart with a spoon as it cooks.

Once browned and cooked through, drain excess grease if necessary.

4. Add the Onion and Garlic

Add the chopped onion to the skillet and cook for 3–4 minutes, until softened.

Add the minced garlic and cook for another 30 seconds.

Season with the salt, black pepper, and paprika if using.

Stir well and remove from the heat.

5. Prepare the Creamy Sauce

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

If using cream of chicken soup instead, prepare it the same way.

The sauce should be pourable but still fairly thick.

6. Layer the Casserole

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

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

Sprinkle with some of the cheddar cheese.

Pour a portion of the creamy soup mixture over the layer.

Repeat with another layer of potatoes, the remaining beef mixture, more cheese, and the remaining sauce.

Finish with the remaining cheddar cheese and the mozzarella, if using.

Try to distribute everything evenly so each serving gets potatoes, beef, sauce, and cheese.

7. Cover and Bake

Cover the baking dish tightly with aluminum foil.

Bake for about 45 minutes.

Keeping the casserole covered during the first part of baking helps the potatoes steam and become tender.

8. Finish Baking

Remove the foil and continue baking for another 15–20 minutes, or until the potatoes are fork-tender and the cheese on top is melted and golden.

If you want a more browned cheese topping, broil for 1–2 minutes at the end, watching carefully.

9. 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.

Recipe Tips for Success

Slice the Potatoes Thinly

The potatoes should be about ⅛ inch thick. Thick slices may take longer to become tender and can cause the casserole to cook unevenly.

Use Similar-Sized Potato Slices

Try to keep the slices as uniform as possible. A mandoline slicer can make this easier, but a sharp knife works too.

Don’t Skip the Covered Baking Time

Covering the casserole helps trap steam, which is important for cooking the potatoes until tender.

Let It Rest

Allowing the casserole to rest for 10 minutes after baking helps the layers hold together better when serving.

Check the Potatoes

Before removing the casserole from the oven, insert a fork or knife into the center. The potatoes should be tender without resistance.

Ingredient Substitutions

Ground beef: Ground turkey works well for a lighter option.

Russet potatoes: Yukon Gold potatoes can be used. They have a naturally buttery texture and hold their shape well.

Cheddar cheese: Colby Jack, Monterey Jack, or a Mexican-style cheese blend can be substituted.

Mozzarella: This is optional, but it adds extra stretch and meltiness. You can replace it with additional cheddar if preferred.

Cream of mushroom soup: Cream of chicken soup works well if you prefer a different flavor.

Milk: Whole milk gives the creamiest result, but 2% milk can also be used.

Recipe Variations

Bacon Cheeseburger Potato Casserole

For a cheeseburger-inspired version, add cooked beef bacon pieces between the layers and top with extra cheddar.

Turkey Potato Casserole

Use lean ground turkey and cream of chicken soup for a lighter variation.

Loaded Potato Casserole

Add cooked corn, diced bell peppers, or sliced mushrooms to the beef mixture.

Spicy Hamburger Potato Casserole

Add crushed red pepper flakes, diced jalapeños, or a little hot sauce to the beef mixture.

Extra Cheesy Potato Casserole

Use a combination of cheddar, mozzarella, and Monterey Jack for an extra-melty topping.

What to Serve with Hamburger Potato Casserole

Since this casserole is already hearty, lighter sides work especially well.

Try serving it with:

• Green salad
• Steamed broccoli
• Roasted green beans
• Glazed carrots
• Cucumber salad
• Roasted vegetables
• Simple tomato salad

How to Store Leftovers

Allow the casserole to cool before transferring leftovers to an airtight container or covering the baking dish tightly.

Store in the refrigerator for up to 3–4 days.

Reheat individual portions in the microwave or reheat larger portions in a covered oven-safe dish at 350°F (175°C) until hot throughout.

Can You Freeze Hamburger Potato Casserole?

Yes, although potatoes can become slightly softer after freezing and thawing.

For best results, allow the casserole to cool completely before placing it in a freezer-safe container.

Freeze for up to 2–3 months.

Thaw overnight in the refrigerator, then reheat covered at 350°F (175°C) until heated through. Remove the cover during the final few minutes to refresh the cheesy topping.

Frequently Asked Questions

Can I make this casserole ahead of time?

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

Why are my potatoes still hard?

The potato slices may be too thick, or the casserole may not have been covered long enough. Slice the potatoes to about ⅛ inch and keep the dish tightly covered during the first 45 minutes of baking.

Can I use frozen potatoes?

Yes, although fresh thinly sliced potatoes provide the best texture for this recipe. If using frozen potatoes, adjust the cooking time according to the product.

Can I use ground turkey?

Absolutely. Ground turkey can be substituted for ground beef in the same amount.

Can I make this without cream of mushroom soup?

Yes. Cream of chicken soup is an easy substitute. You can also use a homemade creamy sauce if preferred.

Can I add vegetables?

Yes. Corn, peas, mushrooms, spinach, or diced bell peppers can all be added to the beef mixture.
