For the Potatoes and Sauce

• 3 tablespoons unsalted butter
• 3 tablespoons all-purpose flour
• 2 cups whole milk
• 1 cup low-sodium beef broth
• ½ teaspoon salt

How to Make Cheesy Hamburger Potato Casserole

1. Preheat the oven.
   Heat the oven to 375°F. Lightly coat a 9-by-13-inch baking dish with cooking spray or butter.
2. Prepare the potatoes.
   Peel the potatoes, if desired, and cut them into slices about ⅛ inch thick. A mandoline slicer makes this quicker, but a sharp knife also works.Keep the slices close to the same thickness so they cook evenly. Place them in a bowl of cold water while you prepare the filling, then drain and pat them dry.
3. Cook the onion.
   Heat the olive oil in a large skillet over medium heat. Add the chopped onion and cook for 3 to 4 minutes, stirring occasionally, until softened.
4. Brown the beef.
   Add the ground beef and break it into small crumbles with a wooden spoon. Cook for 6 to 8 minutes, or until no pink remains.Drain excess grease from the skillet, leaving a small amount behind for flavor.
5. Season the filling.
   Stir in the garlic, salt, black pepper, paprika, garlic powder, onion powder, tomato paste, and Worcestershire sauce.Cook for another 1 to 2 minutes, stirring well, until the tomato paste darkens slightly and the garlic smells fragrant. Remove the skillet from the heat.
6. Start the creamy sauce.
   Melt the butter in a medium saucepan over medium heat. Sprinkle in the flour and whisk continuously for about 1 minute.The mixture should look smooth and lightly foamy. Cooking the flour briefly removes its raw taste.
7. Add the liquids.
   Slowly pour in the milk while whisking constantly. Add the beef broth, salt, black pepper, and dried thyme.Continue cooking for 4 to 6 minutes, stirring often, until the sauce thickens enough to lightly coat the back of a spoon.
8. Add the cheddar.
   Remove the saucepan from the heat and stir in ½ cup of the shredded cheddar. Mix until the cheese has melted and the sauce is smooth.
9. Build the first layer.
   Arrange half of the potato slices across the bottom of the prepared baking dish, slightly overlapping them.Spoon half of the seasoned beef over the potatoes, then pour about one-third of the cheese sauce evenly over the top.
10. Add the remaining layers.
    Arrange the remaining potato slices over the beef. Top with the rest of the ground beef and pour the remaining sauce over everything.Press the layers gently with the back of a spoon so the sauce settles between the potatoes.
11. Bake the casserole covered.
    Cover the baking dish tightly with aluminum foil. Bake for 50 minutes.Carefully insert a thin knife into the center. The potatoes should be starting to soften but may still feel slightly firm.
12. Add the cheese topping.
    Remove the foil and sprinkle the remaining cheddar and all the mozzarella over the casserole.Return it to the oven uncovered and bake for another 20 to 25 minutes, or until the potatoes are tender and the cheese is bubbling with golden spots.
13. Rest before serving.
    Let the casserole stand for 10 minutes before cutting. This short rest allows the sauce to thicken and keeps the layers from sliding apart.Sprinkle with chopped parsley before serving, if desired.

Recipe Notes and Tips

Slice the potatoes thinly

Thick potato slices take much longer to soften. Aim for slices approximately ⅛ inch thick and keep them as even as possible.

If your slices are thicker, the casserole may need an additional 10 to 15 minutes of covered baking time.

Use the right potatoes

Russet potatoes create soft, tender layers and absorb plenty of sauce. Yukon Gold potatoes hold their shape slightly better and have a naturally buttery flavor.

Do not skip the covered baking time

Covering the dish traps steam and helps cook the potatoes evenly. Removing the foil too early may leave the center firm while the cheese browns too quickly.

Make it ahead

Assemble the casserole, cover it tightly, and refrigerate it for up to 24 hours before baking. Let the dish sit at room temperature while the oven heats.

A cold casserole may require an extra 10 to 15 minutes in the oven.

Try simple substitutions

Ground turkey or ground chicken can replace the beef. Monterey Jack, Colby Jack, or a mild cheese blend can replace part of the cheddar.

For extra vegetables, add one cup of cooked mushrooms, diced bell peppers, or frozen peas to the beef mixture.

Storage and reheating

Store leftovers in an airtight container in the refrigerator for up to four days.

Reheat individual portions in the microwave or cover the baking dish and warm it at 350°F until heated through. Add a splash of milk if the sauce seems dry.

Frequently Asked Questions

Why are my potatoes still hard?

The slices may be too thick, or the casserole may not have been covered tightly enough. Cover the dish again and continue baking until a knife passes easily through the center.

Can I use frozen sliced potatoes?

Yes. Thawed frozen potato slices can work, but pat them dry before layering. Excess moisture may thin the sauce.

Can Cheesy Hamburger Potato Casserole be frozen?

Yes. Let the baked casserole cool completely, then wrap it tightly and freeze it for up to two months. Thaw it overnight in the refrigerator before reheating.

What should I serve with hamburger potato casserole?

Serve it with green beans, steamed broccoli, roasted carrots, corn, or a crisp garden salad. A simple vegetable side balances the rich beef, potatoes, and cheese.

A Cozy Dinner for the Whole Table

Cut into the casserole while it is still warm and the cheese stretches between the tender potato layers and seasoned beef. It is hearty, familiar food—the kind of dinner that makes everyone linger near the baking dish, hoping there is enough left for seconds.
