Description
A hearty and comforting scalloped potato casserole layered with seasoned ground beef and creamy cheese sauce, perfect for a satisfying family dinner.
Ingredients
1 1/2 pounds russet potatoes, peeled and thinly sliced
1 pound lean ground beef
1 medium yellow onion, finely chopped
3 cloves garlic, minced
2 tablespoons olive oil
3 tablespoons all-purpose flour
2 cups whole milk
1 cup low-sodium beef broth
1 teaspoon salt
1/2 teaspoon black pepper
1/2 teaspoon dried thyme
1/4 teaspoon paprika
2 cups shredded sharp cheddar cheese, divided
1/4 cup grated Parmesan cheese
2 tablespoons unsalted butter
2 tablespoons chopped fresh parsley, for garnish
Instructions
Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or non-stick spray.
In a large skillet, heat olive oil over medium heat. Add the chopped onion and cook until translucent, about 4 minutes.
Add the minced garlic and cook for another 1 minute until fragrant.
Add the ground beef to the skillet. Cook, breaking it up with a spoon, until browned and cooked through, about 7-8 minutes. Drain excess fat if necessary.
Season the beef mixture with 1/2 teaspoon salt, 1/4 teaspoon black pepper, and 1/2 teaspoon dried thyme. Stir well and remove from heat.
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes until lightly golden, stirring constantly.
Gradually whisk in the milk and beef broth. Continue whisking until the sauce thickens and starts to bubble, about 5-7 minutes.
Remove the sauce from heat and stir in 1 1/2 cups shredded cheddar cheese, 1/4 teaspoon black pepper, 1 teaspoon salt, and paprika until melted and smooth.
Arrange half of the sliced potatoes evenly in the prepared baking dish.
Spread the cooked ground beef mixture evenly over the potatoes.
Pour half of the cheese sauce over the beef layer.
Add the remaining sliced potatoes on top, spreading them evenly.
Pour the remaining cheese sauce over the top layer of potatoes.
Sprinkle the remaining 1/2 cup shredded cheddar cheese and the grated Parmesan cheese evenly over the casserole.
Cover the baking dish tightly with aluminum foil and bake for 45 minutes.
Remove the foil and bake uncovered for an additional 20-25 minutes, or until the potatoes are tender and the top is golden brown and bubbly.
Remove from the oven and let the casserole rest for 10 minutes before serving.
Garnish with chopped fresh parsley and serve warm.

Mastering the Ultimate Scalloped Potato Casserole with Ground Beef
The Secret to That Golden Crust: Timing and Cheese Choices
When it comes to baking scalloped potatoes, the crust often makes or breaks the dish—no joke. Here, the magic lies in layering cheese thoughtfully and knowing exactly when to ditch the foil. The recipe’s call for covering the casserole initially traps moisture, allowing those potato slices to steam and soften fully. But patience is key—you can’t skip the last 20-25 minutes uncovered. That’s when the cheddar and Parmesan get to work, transforming from mere toppings to a golden, bubbly, slightly crispy blanket that sings in contrast to the creamy layers below. I’ve learned the hard way: pull it out too soon, and your top stays pale and floppy; too late, and it burns into a bitter mess. The cheddar’s sharpness paired with Parmesan’s nuttiness isn’t accidental—each brings a different punch to the crust, creating depth and complexity in flavor and texture. Trust me, this is not just cheese on top—it’s the finale your casserole deserves.
Ingredient Swaps That Won’t Throw Off the Groove
Not a fan of beef? No sweat. Ground turkey or even shredded rotisserie chicken can slide in just fine, though you’ll want to amp up the seasoning — a pinch more thyme, a dash of smoked paprika to keep things interesting. For dairy, whole milk is king here, but if you’re skimming calories or dairy, try half-and-half or a full-fat oat milk — just keep a close eye on sauce thickness. Flour acts as the thickener, but swapping it for cornstarch or arrowroot powder will need a little finesse with timing and heat to avoid a runny sauce.
Oh, and potatoes? Russets are your best bet for their high starch content that breaks down just right, but Yukon Golds bring a buttery flavor and creamier mouthfeel. Don’t go wild with waxy potatoes—they won’t soften like they should and might throw off your layering game.
Fixing Common Fails: When Your Casserole’s a Hot Mess
Ever sliced into what should be a beautiful scalloped potato only to find a soupy, under-set mess? It’s usually a thickener issue—either not enough flour or the milk-to-flour ratio got funky. To rescue your sauce, whisk a quick slurry (one tablespoon flour mixed with cold milk) into your bubbling sauce and let it thicken a bit longer before layering.
Burnt edges? Oven heat hotspots are the culprits. Rotate your dish halfway through baking, or nestle the pan on a middle rack away from the broiler. And if your potatoes come out stiff or crunchy? Two things: slice them razor-thin and make sure to cover the dish for those first 45 minutes; steam is your friend here.
Finally, flavor falling flat? Don’t be shy to tweak seasoning at every stage—salt the beef well, pepper the sauce, and toss in fresh herbs like parsley at the end for that final kick. Trust me, scalloped potatoes aren’t just about layers of things—they’re layers of flavor, texture, and a little kitchen savvy.
Scalloped Potato Casserole with Ground Beef: FAQs
- Can I use different potatoes?
- Absolutely. Yukon Golds can add a buttery touch, but russets hold up best in this bake without turning mushy.
- Is it okay to prep ahead?
- Yes, you can assemble the casserole a day ahead and keep it refrigerated. Just add 10-15 minutes to the baking time if you bake it cold.
- Can I swap ground beef for something else?
- Sure thing! Ground turkey or pork works fine if you want to change up the protein. Just season accordingly.
- Does it freeze well?
- No. This casserole doesn’t freeze like a champ — potatoes get watery and textures shift.
- How do I get that perfect golden crust?
- Easy trick: baking uncovered for the last 20-25 minutes crisps up the top nicely. Resist the urge to peek too often or the heat escapes and slows browning.
