Layered Scalloped Potatoes Hamburger Casserole

There’s something about the combination of scalloped potatoes and ground beef that just feels like home. I grew up eating both dishes separately, but once I tried them together in one pan, I wondered why anyone would make them any other way. You get creamy, cheesy potatoes with seasoned beef all in one bite. It’s the kind of dinner that makes everyone at the table happy.

The best part is that this casserole looks like you spent hours in the kitchen, but it’s actually pretty straightforward to put together. You brown the beef, make a simple cream sauce, layer everything up, and let the oven do the rest. I like to prep it in the afternoon and pop it in when we’re ready for dinner. The whole house smells incredible while it bakes.

This is one of those recipes I make on repeat during busy weeks. It feeds a crowd, reheats well for leftovers, and uses ingredients I usually have on hand. Plus, it’s filling enough that I don’t need to worry about making a bunch of side dishes.

What Kind of Potatoes Should I Use?

For this scalloped potatoes hamburger casserole, you’ll want to reach for starchy potatoes like russets or Yukon golds. Russets are the classic choice because they break down slightly during cooking and soak up all that creamy sauce beautifully. Yukon golds are a great alternative if you prefer a creamier, buttery texture that holds its shape a bit better. Whatever you choose, try to pick potatoes that are similar in size so they cook evenly, and slice them about 1/8 to 1/4 inch thick for the best results. If you’re short on time, you don’t even need to peel them – just give them a good scrub and slice away.

Options for Substitutions

This casserole is pretty forgiving when it comes to swaps, so here are some options that work well:

• Ground beef: Ground turkey, ground chicken, or ground pork all work great here. You can even use Italian sausage (removed from casings) for extra flavor. Just drain any excess fat after browning.
• Potatoes: Russet potatoes are the classic choice, but Yukon golds work nicely too. Just slice them about 1/8-inch thick for even cooking. Sweet potatoes aren’t recommended here as they’ll change the whole flavor profile.
• Cream: If you don’t have cream on hand, you can use all milk instead – just use 3 cups total milk. The sauce will be a bit thinner but still tasty.
• Cheddar cheese: Feel free to mix it up with Monterey Jack, Colby, or a Mexican cheese blend. You can also use half cheddar and half mozzarella for a milder flavor.
• Flour: For a gluten-free version, cornstarch works well – use about 1/4 cup mixed with a bit of cold milk before adding to the warm milk mixture.
• Milk and cream: In a pinch, you can use one 12-ounce can of evaporated milk plus 1 3/4 cups regular milk to replace both the milk and cream.

Watch Out for These Mistakes While Baking

The biggest mistake people make with scalloped potato casseroles is slicing the potatoes unevenly or too thick, which leads to some pieces being undercooked while others turn mushy – aim for consistent 1/8-inch slices using a mandoline or sharp knife for the best results.

Another common error is not draining the ground beef well enough, as excess grease will make your casserole oily and prevent the creamy sauce from setting properly.

To avoid a watery casserole, make sure your milk mixture is well-combined with no flour lumps, and don’t skip covering the dish with foil for the first hour since this traps steam and helps the potatoes cook through evenly.

If the top is browning too quickly during the final uncovered baking time, tent it loosely with foil to prevent burning while the inside finishes cooking.

What to Serve With Scalloped Potatoes Hamburger Casserole?

This casserole is pretty hearty on its own, so I like to keep the sides simple and fresh to balance out all that cheesy goodness. A crisp green salad with a tangy vinaigrette is my go-to since it cuts through the richness of the cream and cheese. Steamed green beans or roasted broccoli also work great if you want something warm on the side. If you’re feeding a crowd, some buttery dinner rolls are perfect for soaking up any extra sauce left on your plate.

Storage Instructions

Store: This casserole is a great make-ahead meal! Once it’s cooled down, cover it tightly with foil or transfer to an airtight container and keep it in the fridge for up to 4 days. The flavors actually get even better the next day, so it’s perfect for leftovers.

Freeze: You can freeze this casserole either before or after baking. If freezing unbaked, assemble everything and wrap tightly with plastic wrap and foil for up to 3 months. For already baked casserole, let it cool completely, then wrap well and freeze for up to 2 months.

Reheat: To warm up leftovers, cover with foil and bake at 350°F for about 20-25 minutes until heated through. If reheating from frozen, thaw in the fridge overnight first. You can also microwave individual portions for a quick lunch, just add a splash of milk if it seems a bit dry.

• Calories: 4700-5200
• Protein: 170-200 g
• Fat: 260-300 g
• Carbohydrates: 370-410 g

Ingredients

For the meat mixture:

• 1.25 lb ground beef
• 2 tbsp unsalted butter (I like Kerrygold for the richest flavor)
• 1 large onion (diced into 1/4-inch pieces)

For the cream sauce:

• 2 cups milk (room temperature, about 70°F, to prevent curdling)
• 1 cup cream
• 1/3 cup flour (I always use King Arthur all-purpose flour)
• 2.5 tsp salt
• 1.5 tsp black pepper
• 1/2 tsp garlic powder
• 1/2 tsp smoked paprika

For the casserole layers:

• 3 lb potatoes (peeled and sliced into 1/8-inch rounds)
• 3.5 cups cheddar cheese (freshly shredded for better melting)

Step 1: Prepare Mise en Place and Preheat Oven

• 3 lb potatoes
• 1 large onion
• 2.5 tsp salt
• 1.5 tsp black pepper
• 1/2 tsp garlic powder
• 1/2 tsp smoked paprika
• 3.5 cups cheddar cheese

Preheat your oven to 350°F and grease a 9×13 inch baking dish.

Peel the potatoes and slice them into 1/8-inch rounds—I find using a mandoline makes this quick and consistent, which helps them cook evenly.

Dice the onion into 1/4-inch pieces and measure out all your dry seasonings (salt, pepper, garlic powder, and smoked paprika) into a small bowl.

Have your shredded cheddar cheese ready.

Step 2: Brown the Ground Beef and Sauté the Onions

• 2 tbsp unsalted butter
• 1 large onion
• 1.25 lb ground beef

Heat the butter in a large skillet over medium-high heat.

Once melted and foaming, add the diced onion and cook for 1-2 minutes until just softened and fragrant.

Add the ground beef to the same skillet and cook, breaking it up as it browns, until no pink remains (about 5-7 minutes).

Drain any excess fat from the skillet and set the beef-onion mixture aside to cool slightly.

Step 3: Create the Creamy Sauce

• 2 cups milk
• 1 cup cream
• 1/3 cup flour
• dry seasoning mixture from Step 1

In a medium bowl, whisk together the room-temperature milk and cream.

In a separate small bowl, combine the flour with the measured seasonings from Step 1.

Slowly add the flour mixture to the milk mixture while whisking constantly to prevent lumps from forming.

Whisk until smooth and well combined—the sauce should coat the back of a spoon.

I always add the flour gradually to avoid any clumpy spots, which can ruin the creamy texture.

Step 4: Layer the Casserole

• sliced potatoes from Step 1
• beef-onion mixture from Step 2
• cheese from Step 1
• creamy sauce from Step 3

Spread one-third of the sliced potatoes in an even layer on the bottom of your prepared baking dish.

Top with half of the beef-onion mixture from Step 2, then sprinkle with one-third of the shredded cheese.

Pour one-third of the creamy sauce from Step 3 over the top.

Repeat these layers: potatoes, remaining beef mixture, cheese, and sauce.

Finish with the final third of potatoes, remaining cheese, and remaining sauce.

The sauce should come about two-thirds of the way up the dish.

Step 5: Bake Covered, Then Uncover to Finish

Cover the baking dish tightly with foil and place in the preheated 350°F oven.

Bake for 60 minutes—the foil traps steam and helps the potatoes cook through evenly.

After 60 minutes, carefully remove the foil (watch for hot steam).

Return the dish to the oven uncovered and bake for another 20 minutes until the top is golden brown and the potatoes are tender when pierced with a fork.

Let the casserole rest for 5 minutes before serving so it sets slightly and is easier to portion.
