What is Easy Cheesy Hamburger Potato Casserole?

At its heart, Easy Cheesy Hamburger Potato Casserole is a classic meat-and-potatoes bake. Think of it like shepherd’s pie meets scalloped potatoes, but without all the fuss. You layer thin slices of russet potatoes with seasoned ground beef and a rich, creamy sauce, then top the whole thing with melty mozzarella and cheddar cheese. The result? A bubbling, golden-brown dish that feeds a crowd and leaves bellies happy.

It’s the kind of recipe that came out of necessity—busy weeknights, tight budgets, and no time for fancy. But don’t let the simplicity fool you—it delivers big on flavor, texture, and comfort. Plus, with a few tweaks, it can easily be made gluten-free or dairy-free. It’s a back-pocket meal you’ll reach for again and again, whether you’re hosting family or reheating it for tomorrow’s lunch.

Reasons to Try Easy Cheesy Hamburger Potato Casserole

Instructions to Make Easy Cheesy Hamburger Potato Casserole

Ready to bring some serious comfort to your dinner table? This step-by-step guide will walk you through making Easy Cheesy Hamburger Potato Casserole from start to bubbly-cheesy finish. Whether you’re new to casseroles or just want a foolproof method, this guide breaks it all down—no guesswork, no confusion, just creamy, beefy goodness. Follow each step carefully for a successful (and tasty) result every time.

Step 1: Preheat the Oven and Prep Your Baking Dish

Start this step-by-step recipe by preheating your oven to 375°F (190°C). This ensures it’s hot and ready when your casserole is assembled—no waiting around with raw potatoes in hand.

Next, grab a 9×13-inch baking dish and grease it well with either butter or non-stick cooking spray. This prevents sticking and makes cleanup much easier. If you’re prepping ahead, consider using a foil pan for quick storage and freezer-friendly convenience.

Step 2: Brown the Ground Beef

In a large skillet over medium heat, cook 2 lbs. of ground beef until it’s fully browned and no longer pink. Use a spatula to break it apart into crumbles as it cooks. This is your base layer of flavor, so don’t rush it.

Important: Once the beef is browned, drain all the fat. Yes, all of it. Leaving extra grease can lead to a soggy or greasy casserole. This step might seem small, but it’s the difference between a rich, flavorful bake and a soupy mess.

If you’re using a leaner meat or want to explore alternatives, consider swapping in ground turkey or even plant-based crumbles. Our Healthy Hobo Casserole uses similar swaps for a lighter take.

Step 3: Add Onion, Garlic, and Seasonings

Once the beef is drained, stir in 1¼ cups chopped onion and 3 cloves of minced garlic. Let them cook for about 2–3 minutes, just until the onion becomes soft and fragrant.

Now, add your flavor builders:

• 2 tsp Worcestershire sauce
• 1 tsp garlic powder
• ½ tsp onion powder
• 1 tsp paprika
• Salt and pepper to taste

Mix everything together thoroughly and then remove the pan from heat. At this point, your kitchen should already smell amazing.

Step 4: Make the Creamy Roux Sauce

Now for the silky sauce that brings it all together. In a medium saucepan, melt 2½ tablespoons of butter over medium heat. Once it’s melted, whisk in 2½ tablespoons of gluten-free all-purpose flour (or regular flour if you’re not avoiding gluten). Stir constantly for 1–2 minutes—you want a smooth paste called a roux, without any lumps.

Next, slowly whisk in 1 cup of milk (plant-based or whole) and ½ cup of beef broth. Add the liquid gradually, whisking as you go to keep the sauce lump-free. Cook until it begins to thicken—about 4–5 minutes.

Remove the saucepan from heat, then stir in ¾ cup Greek yogurt. Add salt and pepper to taste. The result should be a creamy, slightly tangy sauce that adds body and richness to your casserole.

Shortcut alert: If you’re in a pinch, you can substitute with a condensed cream of mushroom soup mixed with ¾ cup milk.

Step 5: Slice the Potatoes

Now it’s time for your potatoes. 3 medium Russet potatoes sliced into ¼-inch thick rounds work best. You can leave the skins on for extra texture and nutrients—just make sure they’re scrubbed clean.

Using a mandoline slicer speeds things up and gives you even slices, which helps the potatoes cook evenly. Just be careful—those blades are sharp. If you’re unsure, check out our kitchen prep tips.

Step 6: Build the Casserole (Layer by Layer)

Here comes the fun part! Start layering in your greased baking dish:

1. Add a single, even layer of half your potato slices.
2. Spoon half of the beef mixture over the potatoes.
3. Pour half of the cream sauce over the beef and spread it out.

Repeat the layers with the remaining potatoes, remaining beef, and the rest of the sauce. Use a spoon or spatula to spread everything evenly so every bite has that perfect blend of meat, potatoes, and sauce.

Step 7: Add Cheese and Bake

Top everything off with 1 cup shredded mozzarella and 1 cup shredded sharp cheddar. Spread the cheese evenly across the top, making sure to hit the corners—those melty, crispy edges are gold.

Cover the dish tightly with aluminum foil and bake at 375°F for 45–50 minutes, or until the potatoes are fork-tender. Remove the foil and bake for an additional 10–15 minutes, until the cheese is bubbly and golden brown.

Want an extra layer of flavor? Sprinkle a little paprika or chopped parsley over the top right before serving.

Step 8: Rest Before Serving

Once it’s out of the oven, let the casserole sit for at least 10 minutes. This gives everything time to settle, making it easier to slice and serve without falling apart. Plus, no one likes scalding their tongue on molten cheese (we’ve all been there).

This casserole pairs beautifully with a side of roasted green beans or a crisp salad for balance.

What to Serve with Easy Cheesy Hamburger Potato Casserole

This dish is hearty on its own, but if you’re looking to round out the plate, here are a few easy options. A crisp green salad or roasted broccoli adds freshness and crunch. Garlic green beans, sautéed zucchini, or even a bowl of soup—like this Healing Cabbage Soup—make great pairings. If you’re carb-happy, buttery dinner rolls or even a side of rice (for the extra hungry folks) will hit the spot. You can also serve this with sour cream or hot sauce on the side if your crowd likes to customize.

Key Tips for Making Easy Cheesy Hamburger Potato Casserole

1. Slice Evenly: Try to keep your potato slices even (¼-inch thick) so they cook at the same rate. Thinner slices = faster cooking.
2. Drain the Fat: Seriously, don’t skip this. Greasy casseroles are no fun and mess with the texture.
3. Customize It: Add bell peppers, spinach, mushrooms, or jalapeños for more flavor. It’s a very forgiving recipe.
4. Make It Ahead: Assemble the whole thing in the morning, cover it, and keep it in the fridge until dinner. Just bake a little longer if it’s going in cold.
5. Use a Mandoline (Carefully): For speedy, uniform potato slices. But please watch those fingertips.

Storage and Reheating Tips for Easy Cheesy Hamburger Potato Casserole

Leftovers? Lucky you. This casserole keeps beautifully. Just store in an airtight container and refrigerate for up to four days. To reheat, pop a slice in the microwave for 2–3 minutes, or warm the whole dish in a 350°F oven until heated through (usually 15–20 minutes). Want to freeze it? Go for it—but freeze before baking. Assemble it in a disposable pan, cover tightly with foil and freeze for up to 3 months. When you’re ready, bake from frozen at 375°F for about 75–90 minutes (covered), then uncover for the last 15. Add cheese near the end so it stays melty and fresh.

Ground turkey or chicken work great. You can even try plant-based crumbles for a vegetarian version.
