Cheesy Scalloped Potatoes Recipe

If you’re looking for the kind of comforting, crowd-pleasing side dish that makes everyone sneak a second spoonful, this Cheesy Scalloped Potatoes Recipe is it—creamy, golden, rich, and perfect for holidays, Sunday suppers, or frankly, any night you need a little comfort on the table.

A Cozy, Creamy Favorite That Never Goes Out of Style

There’s something about a bubbling pan of cheesy scalloped potatoes that feels like home. Thinly sliced potatoes baked in a creamy cheese sauce—soft in the middle, golden on top, and packed with that old-fashioned comfort we all know and love. It’s one of those dishes that sits somewhere between a classic potato recipe and a special-occasion casserole, which is probably why it shows up at Easter, Thanksgiving, Christmas, potlucks, and weeknight dinners alike.

I’ve been making some version of this scalloped potatoes recipe for years, especially when I want a side dish that feels a little extra without making me work too hard. And let me tell you, this one hits that sweet spot. It’s rich, yes, but not fussy. Creamy, but still structured enough to slice and serve. Think of it as the happy middle ground between traditional homemade scalloped potatoes and indulgent au gratin potatoes.

What makes this version special is the balance. You get tender layers of Yukon Gold or Russet potatoes, a homemade cheese sauce that’s silky instead of gluey, and just enough seasoning to keep the whole dish from tasting flat. A lot of recipes lean too heavy on cream or cheese and forget the basics. Not this one. Every bite tastes like it was made with care.

And if you’re feeding family, especially a mixed crowd of picky eaters and hungry holiday guests, this cheesy potato casserole tends to disappear fast. It’s a warm, dependable comfort food side dish that works with ham, roast chicken, pork chops, steak, even a simple green salad if you want to keep things easy.

Ingredients You’ll Need

Here’s everything you need for this baked scalloped potatoes dish:

2 1/2 pounds Yukon Gold or Russet potatoes, peeled and thinly sliced to about 1/8 inch
(Yukon Golds are naturally buttery; Russets give a softer, more classic casserole texture.)
3 tablespoons unsalted butter
1 small yellow onion, very thinly sliced
(Optional, but it adds wonderful depth.)
3 cloves garlic, minced
3 tablespoons all-purpose flour
2 cups whole milk
1 cup heavy cream
(You can swap in half-and-half for a slightly lighter sauce.)

2 cups shredded sharp cheddar cheese, divided
(Tillamook and Cabot both melt beautifully.)
1 cup shredded Gruyère cheese
(Or use Monterey Jack for a milder flavor.)
1 1/2 teaspoons kosher salt
1/2 teaspoon black pepper
1/2 teaspoon paprika
1/4 teaspoon ground thyme or 1 teaspoon fresh thyme leaves
Cooking spray or butter, for greasing the baking dish
2 tablespoons chopped fresh parsley, for garnish (optional)

A quick tip: if you have a mandoline slicer, now’s the time to use it. Even slices mean even baking, and that matters in a sliced potato bake like this.

How to Make Cheesy Scalloped Potatoes

Preheat the oven and prep the dish.
Set your oven to 375°F. Grease a 9×13-inch baking dish with butter or cooking spray. This little step saves you from scrubbing baked-on cheese later, and I’m all for that.

Slice the potatoes.
Peel the potatoes and slice them into thin, even rounds, about 1/8 inch thick. If the slices are too thick, the potatoes can stay firm in the center. Too thin, and they may fall apart. A mandoline makes this easy, but a sharp chef’s knife works too.
Start the sauce with butter, onion, and garlic.
In a large saucepan over medium heat, melt the butter. Add the sliced onion and cook for about 4 to 5 minutes until softened. Stir in the garlic and cook for 30 seconds, just until fragrant. Don’t let the garlic brown—it can turn bitter fast.
Make the roux.
Sprinkle in the flour and stir constantly for about 1 minute. It should look like a thick paste. This step helps thicken the sauce so your creamy potato side dish stays luscious instead of watery.

Add the milk and cream.
Slowly whisk in the milk and heavy cream. Keep whisking so you don’t get lumps. Add the salt, pepper, paprika, and thyme. Let the mixture simmer for 3 to 5 minutes, stirring often, until it thickens slightly and coats the back of a spoon.
Stir in the cheese.
Remove the pan from the heat and stir in 1 1/2 cups cheddar and 1 cup Gruyère until smooth. The sauce should be silky and rich. If it seems too thick, add a splash of milk. If it tastes a little too bold on its own, don’t worry—the potatoes mellow everything out.
Layer the potatoes and sauce.
Arrange half the potato slices in the prepared baking dish, overlapping them slightly. Spoon over half the cheese sauce. Repeat with the remaining potatoes and sauce. Make sure the top is evenly coated so the whole casserole bakes consistently.

Top with the remaining cheese.
Sprinkle the last 1/2 cup cheddar over the top. This gives you that irresistible golden finish that makes cheesy baked potatoes so hard to resist.
Cover and bake.
Cover the dish tightly with foil and bake for 45 minutes. Covering it first traps steam, which helps the potatoes soften without drying out.
Uncover and finish baking.
Remove the foil and bake for another 25 to 30 minutes, until the top is golden and the potatoes are fork-tender. If you want more color, broil for 2 to 3 minutes at the end—but keep an eye on it. Cheese goes from golden to scorched in a blink.

Rest before serving.
Let the dish sit for 10 to 15 minutes before serving. I know, waiting is hard. But that rest time helps the sauce settle so you get neat, creamy portions instead of a runny scoop.

Servings & Timing

Yield: 8 to 10 servings
Prep Time: 20 minutes
Bake Time: 70 to 75 minutes
Rest Time: 10 to 15 minutes
Total Time: About 1 hour 45 minutes

This makes enough for a family dinner with leftovers, or a holiday spread where people go back for seconds. And they usually do.

Variations to Try

Sometimes it’s nice to change things up a bit. This dish is forgiving that way.

Add diced ham for a hearty, all-in-one casserole that works beautifully after Easter.
Use smoked cheddar for a deeper, slightly woodsy flavor.
Layer in cooked bacon for extra savory crunch.
Swap in sweet onions if you want a gentler onion flavor.

Add spinach between the layers for a little color and balance.
Make it extra herby with rosemary or fresh chives on top.

If you love au gratin potatoes, you can also add a handful of Parmesan to the top for a more savory crust.

Storage & Reheating

Leftovers store very well, which is one more reason I keep this recipe in regular rotation.

Refrigerator: Store cooled leftovers in an airtight container for up to 4 days.
Freezer: Freeze tightly wrapped portions for up to 2 months. The texture may soften a little after thawing, but the flavor stays lovely.

Reheating: Warm individual portions in the microwave in 60-second bursts, or reheat the full dish in a 350°F oven covered with foil until hot, about 20 to 25 minutes.
Make-ahead tip: Assemble the casserole up to 24 hours ahead, cover, and refrigerate. Let it sit at room temperature for 20 to 30 minutes before baking.

One little note from experience: if you’re making this ahead, keep the sauce slightly loose. Potatoes absorb liquid as they sit.

Notes From My Kitchen

After testing this recipe a few different ways, here’s what I’ve found works best:

First, don’t rush the sauce. A good cheese sauce is like a good conversation—it starts slow and comes together beautifully if you give it a minute. If you pour in cold milk too fast or crank the heat too high, it can turn lumpy. Gentle heat is your friend here.

Second, slice the potatoes evenly. I know I already mentioned it, but it really matters. Uneven slices mean some pieces go buttery soft while others stay undercooked, and nobody wants that surprise.

Third, sharp cheddar gives the best flavor. Mild cheddar melts fine, sure, but it doesn’t bring enough punch once it’s mixed with cream and potatoes. You need a cheese that can hold its own.

And finally, let the casserole rest. This may be the hardest tip of all, especially when your kitchen smells like heaven, but those 10 minutes make a difference in texture.

FAQs

Can I make this Cheesy Scalloped Potatoes Recipe ahead of time?

Yes, absolutely. You can assemble it a day in advance, cover it tightly, and refrigerate until ready to bake.

What’s the difference between scalloped potatoes and au gratin potatoes?

Traditionally, scalloped potatoes use a cream sauce, while au gratin potatoes include cheese. These days, the names overlap a lot, and many home cooks use them almost interchangeably.

Why are my scalloped potatoes still hard after baking?

Usually the slices were too thick, or the dish needed more time in the oven. Covering the dish for the first part of baking helps steam the potatoes until tender.

Can I use pre-shredded cheese?

You can, but freshly shredded cheese melts more smoothly. Pre-shredded cheese often has anti-caking agents that make the sauce a bit grainy.

Which potatoes work best?

Yukon Golds are my favorite for a creamy, buttery texture. Russets are also great if you want a softer, more classic homemade scalloped potatoes feel.

Can I make this without onions?

Yes. Just leave them out if you prefer. The dish will still be rich, creamy, and delicious.

How do I keep the sauce from curdling?

Use medium or medium-low heat, and don’t boil the dairy aggressively. Also, melt the cheese off the heat for the smoothest finish.

Can I add meat to this recipe?

Definitely. Diced ham, cooked bacon, or even shredded rotisserie chicken can turn this into a heartier cheesy potato casserole.
