The Complete Hamburger Potato Casserole Recipe

This recipe serves 6‑8 people. It bakes in a 9×13 inch baking dish.

Ingredients:

2 lbs (about 900g) russet potatoes (about 4 medium potatoes), peeled and thinly sliced (⅛‑inch thick)

1 lb (450g) lean ground beef (85/15 or 90/10)

1 medium yellow onion, diced

3 cloves garlic, minced

2 tablespoons butter

2 tablespoons all‑purpose flour

1 cup (240ml) beef broth (low‑sodium)

1 cup (240ml) whole milk (or 2% milk)

½ teaspoon salt (plus more for potatoes)

½ teaspoon black pepper

½ teaspoon smoked paprika (or regular paprika)

½ teaspoon dried thyme (or 1 teaspoon fresh)

2 cups (8 oz / 225g) shredded sharp cheddar cheese, divided

Optional garnish: fresh parsley or chives

Equipment:

9×13 inch baking dish

Large skillet

Medium saucepan

Cutting board and knife

Mandoline slicer (optional but helpful for even potato slices)

Aluminum foil

Step‑by‑Step Instructions

Step 1 – Preheat and Prepare

Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with butter or non‑stick spray. Peel the potatoes and slice them very thinly (about ⅛‑inch thick). A mandoline makes this fast and even, but a sharp knife works. Uniform slices ensure even cooking – no crunchy spots.

Step 2 – Cook the Ground Beef

In a large skillet over medium‑high heat, cook the ground beef and diced onion together, breaking up the meat with a spatula. Cook until the beef is browned and the onion is softened, about 5‑7 minutes. Add the minced garlic and cook for 1 more minute. Drain any excess fat. Season with ¼ teaspoon salt and ¼ teaspoon pepper. Set aside.

Step 3 – Make the Creamy Sauce

In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1‑2 minutes until the mixture is bubbly and lightly golden (this is a roux). Gradually whisk in the beef broth and milk, stirring constantly to prevent lumps. Add the remaining ¼ teaspoon salt, ¼ teaspoon pepper, smoked paprika, and dried thyme. Continue whisking until the sauce thickens, about 3‑4 minutes. Remove from heat. The sauce should be smooth and creamy, coating the back of a spoon.

Step 4 – Assemble the Casserole

Arrange half of the sliced potatoes in an even layer on the bottom of the prepared baking dish. Slightly overlap the slices so there are no large gaps. Sprinkle half of the cooked ground beef mixture over the potatoes. Pour half of the creamy sauce over the beef. Sprinkle 1 cup of shredded cheddar cheese on top. Repeat the layers: remaining potatoes, remaining beef, remaining sauce. Do not put the second cup of cheese on yet – that goes on near the end.

Pro tip: Press down gently on the layers with a spatula to help the sauce settle around the potatoes.

Step 5 – Cover and Bake

Cover the baking dish tightly with aluminum foil. Bake for 45 minutes. The foil traps steam, which helps the potatoes cook through without drying out.

Step 6 – Add the Top Cheese and Finish Baking

After 45 minutes, remove the foil. Sprinkle the remaining 1 cup of shredded cheddar cheese over the top. Return the casserole to the oven, uncovered, and bake for another 15‑20 minutes, until the cheese is melted and bubbly and the potatoes are fork‑tender (a knife should slide easily through the center). If you want a golden, slightly crispy top, turn on the broiler for the last 1‑2 minutes – watch carefully to avoid burning.

Step 7 – Rest and Serve

Let the casserole rest for 10‑15 minutes before serving. This allows the layers to set so you can cut clean squares. Garnish with fresh parsley or chives. Serve hot, with a side of green beans, a simple salad, or crusty bread.

Pro Tips for the Best Hamburger Potato Casserole

Follow these expert tips for a perfect make‑ahead potato casserole every time:

Slice potatoes uniformly thin – Thick or uneven slices will lead to undercooked, crunchy potatoes. A mandoline is your best friend here. Aim for ⅛ inch – about the thickness of a quarter.

Do not skip par‑cooking the sauce – The roux‑based sauce ensures creaminess and prevents the casserole from being watery.

Cover for most of the baking time – Uncovered baking dries out the top before the potatoes are tender. Foil is essential for the first 45 minutes.

Use starchy potatoes (russets) – Russet potatoes break down slightly and absorb the creamy sauce. Waxy potatoes (red, Yukon gold) hold their shape but may result in a firmer casserole. Both work, but russets are classic.

Let it rest before cutting – This step is crucial. If you cut too soon, the casserole will be runny. Ten minutes of resting makes clean, beautiful squares.

Season each layer lightly – Potatoes need salt. A little sprinkle of salt and pepper on each potato layer enhances the overall flavor.

Make it ahead – Assemble the casserole completely (without baking), cover, and refrigerate for up to 24 hours. Add 10‑15 minutes to the covered baking time.

Delicious Variations (Same Easy Method)

Once you master the classic hamburger potato casserole, try these fun twists. These ground beef casserole variations will keep your dinner rotation exciting.

1. Hamburger Potato Casserole with Mushrooms

Sauté 8 oz of sliced cremini mushrooms with the ground beef and onion. The mushrooms add an earthy, umami depth. Use Swiss cheese instead of cheddar for a steakhouse feel.

2. Cheesy Hamburger Potato Casserole with Cream Cheese

Add 4 oz of cubed cream cheese to the sauce along with the milk. Stir until melted. This makes the sauce extra creamy and tangy. This is a cream cheese ground beef casserole that is decadent and delicious.

3. Spicy Tex‑Mex Potato Casserole

Add 1 can (4 oz) of diced green chilies, 1 teaspoon of cumin, and ½ teaspoon of chili powder to the ground beef. Use pepper jack cheese instead of cheddar. Top with fresh cilantro, jalapeños, and a dollop of sour cream.

4. Bacon Cheeseburger Potato Casserole

Add ½ cup of cooked, crumbled bacon to the ground beef mixture. Use a blend of cheddar and Monterey Jack. After baking, top with shredded lettuce, diced tomatoes, and a drizzle of thousand island dressing – it tastes just like a bacon cheeseburger.

5. Vegetable‑Loaded Hamburger Potato Casserole

Add 1 cup of finely chopped carrots, 1 cup of frozen peas, and 1 cup of diced zucchini to the ground beef layer. Sauté the vegetables with the onion until softened. This boosts nutrition without sacrificing flavor.

6. Sweet Potato Hamburger Casserole

Replace the russet potatoes with peeled, thinly sliced sweet potatoes. Use sharp cheddar or a blend with Gruyère. The natural sweetness of sweet potatoes pairs beautifully with savory beef.

7. Low‑Carb / Keto Hamburger Potato Casserole

Replace the potatoes with 4 cups of thinly sliced turnips or radishes (both have a potato‑like texture when baked). Use a low‑carb thickener (xanthan gum or almond flour) instead of all‑purpose flour for the sauce. This low‑carb ground beef casserole is just as satisfying.

8. Italian Hamburger Potato Casserole

Add 1 teaspoon of dried oregano, 1 teaspoon of dried basil, and ½ teaspoon of fennel seeds to the ground beef. Use a blend of mozzarella and Parmesan cheese. Serve with a side of marinara sauce for dipping.

How to Store, Freeze, and Make Ahead

Proper storage ensures you can enjoy this budget‑friendly dinner for days or weeks.

Refrigerator (Baked Casserole)

Store leftovers in an airtight container for up to 4 days. The casserole will firm up when cold. Reheat in the microwave or oven.
