Ingredients for Homemade Scalloped Potatoes with Cheese Sauce

Getting these best cheesy scalloped potatoes right starts with getting the ingredients ready. Remember, being organized is half the battle! For the absolute richest, creamiest potato bake recipe, everything needs to be measured out before we even think about turning on the stove. I’ve linked my main recipe page right here if you want to pull up a printable version while you measure.

• 3 lbs Yukon Gold potatoes, peeled and ready for slicing
• 1 tablespoon unsalted butter, plus extra for greasing the dish
• 1/4 cup all-purpose flour (this is for our essential roux!)
• 3 cups whole milk
• 1 cup heavy cream (this makes it decadent!)
• 1 teaspoon salt, don’t skimp here
• 1/2 teaspoon black pepper
• 1/4 teaspoon fresh nutmeg
• 1 clove garlic, minced finely
• 2 cups shredded Gruyère cheese, and this needs to be divided for layering
• 1 cup shredded sharp cheddar cheese
• 1/4 cup grated Parmesan cheese for that perfect golden top

Trust me on the Yukon Golds—they are the secret weapon for this layered potato casserole!

Equipment Needed for the Best Cheesy Scalloped Potatoes

Okay, before we start melting cheese and making that divine sauce, let’s make sure your kitchen is prepped. You don’t need a ton of fancy gadgets, but a couple of things really make the difference between good layered potato casserole and *great* layered potato casserole! Having these things ready means you can focus only on the cooking once you get going.

For this creamy potato bake recipe, here’s what you absolutely need handy:

• A Good Slicing Tool: This is crucial! You need thin, even slices, about 1/8 inch. If you have a mandoline slicer, now is the time to use it—it guarantees consistency. If not, just grab your sharpest knife and take your time on that prep.
• A 9×13 Inch Baking Dish: This is the standard size for this recipe, ensuring the potatoes cook evenly without being too crowded. Make sure you grease it up well!
• A Large Saucepan: This is where the magic happens—making our thick and creamy potato bake sauce. It needs to be big enough to whisk in the milk and cream without splashes.
• A Whisk: You’ll need this to keep that roux smooth and lump-free when adding your liquids.
• Microplane or Box Grater: For shredding that glorious Gruyère and cheddar fresh! Seriously, never use pre-shredded stuff if you can avoid it; it just melts better when you grate it yourself.

That’s it! If you have those basics, you are totally set to make the most incredible, rich baked potatoes and cheese you’ve ever had.

How to Make Perfect Cheesy Scalloped Potatoes: Step-by-Step

Now for the fun part—turning simple potatoes and dairy into that show-stopping, creamy potato bake recipe! Don’t rush this stage. If you follow these few key steps, you’ll master this dish and feel like a kitchen rockstar. I know this looks like a lot of steps, but trust me, once you get into the rhythm, it flows beautifully! I’ve put together a detailed guide on the process over here, but let’s walk through the highlights right now.

Preparing the Potatoes and Oven

First things first, we need to get things hot! Preheat your oven straight away to 375 degrees Fahrenheit, and take a minute to generously grease that 9×13 baking dish with butter. For the potatoes, the key to this entire dish is thickness. If you have a mandoline slicer, use it! Set it to 1/8 inch for those perfectly consistent slices you see in all the best cheesy scalloped potatoes photos. If you’re hand slicing, take your time—even slices cook evenly, which means you get tender potatoes throughout the entire casserole, not just the edges!

SAVE

Creating the Thick and Creamy Potato Bake Sauce

This is where we build our rich baked potatoes and cheese base. In your large saucepan, melt that tablespoon of butter over medium heat, then whisk in the flour for just about a minute—that’s your roux, it needs to cook off a little raw flour taste. Now, here’s the crucial bit: slowly whisk in the milk and heavy cream, a little bit at a time, keeping the whisk moving constantly to avoid lumps! Keep stirring until the sauce thickens enough that it coats the back of a spoon nicely. Once it hits that point, take it off the heat. This prevents it from boiling too aggressively. Now, gently stir in your salt, pepper, nutmeg, and garlic, followed by 1 1/2 cups of the Gruyère and all of that sharp cheddar. Stir until everything melts into one glorious, homemade scalloped potatoes with cheese sauce!

Layering and Baking the Delicious Layered Potato Casserole

Time to assemble! Spread half of your thinly sliced potatoes in an even layer in your prepared dish. Pour half of that cheesy sauce right over the top. Then, repeat that process with the remaining potatoes and the rest of the sauce. Remember that beautiful Gruyère and Parmesan you divided? Sprinkle both of those cheeses over the very top layer. Pop it into the preheated oven for about 50 to 60 minutes. If you notice that gorgeous top crust getting too dark before the potatoes are totally tender, just cover it loosely with aluminum foil for the last 15 minutes. And please, *please* let it rest for 10 minutes after it comes out. That little bit of downtime helps the sauce set up perfectly before you dig in!

Tips for Success with Your Rich Baked Potatoes and Cheese

I want you to feel confident making this creamy potato bake recipe, so let me share the two things I learned the hard way. First, stick with Yukon Gold potatoes whenever possible! Russets get a bit too mushy when they bake that long, but the Yukon Golds stay firm and buttery, giving you the best structure for this layered potato casserole.

Second, remember the sauce instruction: you want it to thicken, but you absolutely must keep it at a simmer, not a rapid boil, when you are adding the milk and cream. If it boils too hard, the roux can break, and we’ll end up with a grainy sauce instead of luxurious comfort.

Variations for Cheesy Scalloped Potatoes

While this classic potato gratin recipe is absolutely perfect as is, I know how much fun it is to tweak things around! Sometimes you have something extra in the fridge, or maybe you just want to change it up for the next time you serve this cheesy potato side for holidays.

If you want to turn this into a true centerpiece meal—a really hearty dish—you absolutely have to try adding some meat! The recipe notes mention it, and trust me, it works magic. Fold in about a cup of cooked, crumbled bacon or maybe some diced ham right in between your layers of potatoes and sauce. It adds the perfect salty, savory bite to balance all that cream and cheese.

Speaking of cheese, while Gruyère gives that beautiful, nutty depth that makes this a truly specialized Gruyere scalloped potatoes recipe, feel free to experiment! If you don’t have Gruyère on hand, swapping it out for an equal amount of white sharp cheddar or maybe even a smoked Gouda adds a whole new layer of flavor complexity. Just remember, when you swap cheeses, make sure you still use about the same total volume so the sauce thickens up correctly. Have fun with it!

Make Ahead Cheesy Potatoes and Storage Instructions

I know the thought of making a massive layered potato casserole on a busy holiday can feel overwhelming, which is why this recipe is fantastic for prep work! You can assemble the entire thing—layering all the potatoes and smothering them in that rich sauce—cover it tight with plastic wrap, and pop it in the fridge for up to 24 hours. That’s right, make ahead cheesy potatoes FTW!

When it’s time to bake, just pull it out, and add about 10 to 15 extra minutes to your usual bake time since it’s starting cold. If you have delicious leftovers (which you should!), they keep great in an airtight container in the fridge for about three days. I usually reheat them slowly, covered with foil, so that creamy sauce stays perfectly intact.

Frequently Asked Questions About Cheesy Scalloped Potatoes

It’s totally normal to have questions when you’re about to make something as important as the main side dish for a holiday gathering! I’ve gathered up the questions I get asked most often about this creamy potato bake recipe to make sure your experience is seamless. Feel free to connect with me on Facebook over here if you have more!

Can I use Russet potatoes instead of Yukon Gold for this cheesy scalloped potatoes recipe?

Oh, that’s a great question! You absolutely *can* use Russets, but you need to know what you’re getting into. Russets have a much higher starch content than our beloved Yukon Golds. What that means for your final classic potato gratin recipe is that the Russets will break down and get softer, bordering on mushy, while they bake. Yukon Golds hold their shape and give you those lovely, defined layers. If you use Russets, just be extra careful not to overcook them, or you’ll end up with more of a mash than baked layers inside your casserole.

What is the secret to a thick and creamy potato casserole sauce?

The absolute secret, and this is key for any truly decadent, thick and creamy potato casserole, is the roux! Don’t skip cooking that flour and butter together for a full minute before adding any liquid. That initial minute is what cooks out the raw flour taste. Then, the key is patience when adding the milk and cream. Whisk slowly, add liquids gradually, and keep the heat at a steady medium until the mixture coats the back of a spoon. If you let it boil rapidly, the sauce can get grainy, and we want that silky, luxurious texture that blankets the potatoes—not lumps! These little steps are what make this dish so incredibly satisfying.

Scale 1x2x3x

• 3 lbs Yukon Gold potatoes, peeled
• 1 tablespoon unsalted butter, plus more for greasing
• 1/4 cup all-purpose flour
• 3 cups whole milk
• 1 cup heavy cream
• 1 teaspoon salt

Cook Mode Prevent your screen from going dark

Instructions

1. Preheat your oven to 375 degrees Fahrenheit. Grease a 9×13 inch baking dish with butter.
2. Slice the potatoes very thinly, about 1/8 inch thick. You can use a mandoline for consistent slices.
3. In a large saucepan over medium heat, melt the 1 tablespoon of butter. Whisk in the flour and cook for one minute, stirring constantly to make a roux.
4. Gradually whisk in the milk and heavy cream until smooth. Continue to cook, stirring often, until the sauce thickens enough to coat the back of a spoon, about 5 to 7 minutes. Do not let it boil rapidly.
5. Remove the sauce from the heat. Stir in the salt, pepper, nutmeg, and minced garlic.
6. Stir in 1 1/2 cups of the Gruyère cheese and all of the sharp cheddar cheese until melted and smooth. This is your rich baked potatoes and cheese sauce base.
7. Arrange half of the sliced potatoes in an even layer in the prepared baking dish. Pour half of the cheese sauce evenly over the potatoes.
8. Top with the remaining potatoes. Pour the remaining cheese sauce over the top layer.
9. Sprinkle the remaining 1/2 cup of Gruyère cheese and the Parmesan cheese over the top layer.
10. Bake for 50 to 60 minutes, or until the potatoes are tender when pierced with a fork and the top is golden brown and bubbly. If the top browns too quickly, loosely cover it with foil for the last 15 minutes.
11. Let the cheesy potato casserole rest for 10 minutes before serving. This allows the sauce to set slightly.

Notes

• For the best texture, use Yukon Gold potatoes; they hold their shape better than Russets when baked.
• You can make this ahead: Assemble the entire dish, cover tightly, and refrigerate for up to 24 hours. Add 10 to 15 minutes to the baking time if baking directly from the refrigerator.
• For a holiday side dish, add 1 cup of cooked, crumbled bacon or diced ham to the layers when assembling.
