Essential Ingredients for Cheesy Scalloped Potatoes
Potatoes: For the best Cheesy Scalloped Potatoes, I strongly recommend using starchy potatoes like Russet or Yukon Gold. Their high starch content helps thicken the sauce and gives that wonderfully creamy texture. They also slice beautifully and hold their shape during baking, which is crucial for perfect Cheesy Scalloped Potatoes.
Cheese Blend: A combination of sharp cheddar and Gruyère is my secret weapon. Cheddar brings that classic, tangy flavor and a great melt, while Gruyère adds a nutty, complex depth that truly elevates the sauce. Don’t skimp on good quality cheese for your Cheesy Scalloped Potatoes; it makes all the difference.
Cream and Milk: Using a mix of whole milk and heavy cream provides the perfect balance of richness without being overly heavy. The higher fat content prevents the sauce from breaking and ensures a silky smooth consistency that coats every slice of your Cheesy Scalloped Potatoes.
How to Make Cheesy Scalloped Potatoes
Prepare Your Potatoes
First things first, you’ll want to peel your chosen potatoes and slice them thinly and evenly. I’ve found a mandoline slicer is truly a game-changer here, ensuring each slice is roughly 1/8 to 1/4 inch thick. This uniformity is key for even cooking and achieving that tender-all-the-way-through texture in your Cheesy Scalloped Potatoes. After slicing, a quick rinse in cold water can remove excess starch, helping to keep your final dish from becoming too gummy.
Craft the Creamy Cheese Sauce
Next up, it’s time to make your luscious cheese sauce. In a saucepan over medium heat, melt some butter, then whisk in flour to create a roux. Cook this for about a minute to toast the flour, then gradually whisk in the milk and cream until smooth. Bring it to a gentle simmer, stirring constantly, until the sauce thickens. Remove from heat and stir in your grated cheeses – watch as they melt into a silky, dreamy sauce that will coat every single piece of your Cheesy Scalloped Potatoes.
Layer and Bake to Perfection
Now for the assembly! Lightly grease a baking dish. I like to start with a thin layer of sauce at the bottom, then arrange a single layer of sliced potatoes, slightly overlapping. Season with salt and pepper, then ladle more sauce over the potatoes, and sprinkle with a bit of cheese. Repeat these layers until all the potatoes are used, finishing with a generous layer of sauce and cheese on top for that beautiful golden crust. Cover with foil and bake, then uncover for the final stretch to get those perfectly browned Cheesy Scalloped Potatoes.
Ingredients
- 2 lbs Russet or Yukon Gold potatoes, peeled and thinly sliced (about 1/8 to 1/4 inch)
- 4 tablespoons unsalted butter
- 4 tablespoons all-purpose flour
- 2 cups whole milk
- 1 cup heavy cream
- 1 teaspoon salt, plus more to taste
- 1/2 teaspoon black pepper, plus more to taste
- 1/4 teaspoon garlic powder (optional, but highly recommended!)
- 1.5 cups shredded sharp cheddar cheese
- 1 cup shredded Gruyère cheese
- Fresh parsley, chopped, for garnish (optional)
Cheesy Scalloped Potatoes Instructions
- Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish (or similar size).
- Prepare the potatoes: Peel the potatoes and slice them uniformly thin using a mandoline or a very sharp knife. Aim for slices between 1/8 to 1/4 inch thick.
- Make the cheese sauce: In a large saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly, to create a roux.
- Gradually whisk in the whole milk and heavy cream until smooth. Continue to whisk as the sauce heats, bringing it to a gentle simmer. It should ticken comfortably within 5-7 minutes.
- Remove the saucepan from the heat. Stir in 1 cup of the cheddar cheese and all of the Gruyère cheese until fully melted and smooth. Season with 1 teaspoon of salt, 1/2 teaspoon of black pepper, and the garlic powder (if using). Taste and adjust seasoning as needed.
- Assemble the Cheesy Scalloped Potatoes: Pour about 1/2 cup of the cheese sauce into the prepared baking dish and spread evenly.
- Begin layering the potatoes in a slightly overlapping pattern over the sauce. Season the potato layer lightly with salt and pepper.
- Pour about 1/3 of the remaining cheese sauce over the potato layer, spreading it evenly. Sprinkle with about 1/4 cup of the remaining cheddar cheese.
- Repeat the potato, sauce, and cheese layering two more times, finishing with a final layer of sauce and the remaining 1/4 cup of cheddar cheese on top.
- Bake the Cheesy Scalloped Potatoes: Cover the baking dish tightly with aluminum foil.
- Bake for 45-55 minutes, or until the potatoes are tender when pierced with a knife.
- Remove the foil and bake for another 15-20 minutes, or until the top is golden brown and bubbly. If the top is browning too quickly, you can loosely tent it with foil again.
- Let the Cheesy Scalloped Potatoes rest for 10-15 minutes before serving. This allows the sauce to set and makes for easier serving. Garnish with fresh parsley, if desired.

Pro Tips for the Best Cheesy Scalloped Potatoes
Use a Mandoline: For perfectly even slices, a mandoline slicer is your best friend when making Cheesy Scalloped Potatoes.
Don’t Overcook the Sauce: Once your cheese sauce thickens, remove it from the heat to prevent it from becoming too thick or breaking.
Resting is Key: Allow your Cheesy Scalloped Potatoes to rest for 10-15 minutes after baking; it helps the layers set beautifully.

Frequently Asked Questions About Cheesy Scalloped Potatoes
Can I make Cheesy Scalloped Potatoes ahead of time?
Absolutely! You can assemble the entire dish up to a day in advance, cover it tightly, and refrigerate. Let it come closer to room temperature for about 30 minutes before baking, and add an extra 10-15 minutes to the covered baking time.
How long does Cheesy Scalloped Potatoes last in the fridge?
Cooked Cheesy Scalloped Potatoes will last for 3-4 days when stored properly in an airtight container in the refrigerator.
Can I freeze Cheesy Scalloped Potatoes?
While technically possible, I don’t typically recommend freezing Cheesy Scalloped Potatoes as the potatoes can become grainy and the sauce may separate upon thawing. It’s best enjoyed fresh or refrigerated.
What kind of cheese is best for Cheesy Scalloped Potatoes?
A good melting cheese is key. I love a blend of sharp cheddar and Gruyère for my Cheesy Scalloped Potatoes, but Monterey Jack, fontina, or even a good provolone work wonderfully too. The rich, creamy texture is what we’re going for.
Why are my Cheesy Scalloped Potatoes not getting tender?
This usually happens if the potato slices are too thick or if the dish isn’t baked long enough, especially if covered. Ensure uniform thin slices and bake until fork-tender, extending covered baking time if necessary.
My cheese sauce for the Cheesy Scalloped Potatoes looks lumpy, what went wrong?
Lumpy sauce is often due to not whisking enough when adding the milk and cream, or adding it too quickly. Always add liquids gradually and whisk continuously to ensure a smooth, lump-free sauce for your Cheesy Scalloped Potatoes. Good quality cheese melts better.
Can I use pre-sliced potatoes?
While convenient, pre-sliced potatoes might not be the ideal choice for Cheesy Scalloped Potatoes as they can sometimes contain additives to prevent browning, which might affect the texture when baked. Freshly sliced is always best.
How do I prevent the sauce from curdling?
To prevent curdling, make sure your sauce doesn’t come to a rolling boil once the cheese is added, and avoid adding cold milk to a very hot roux too quickly. Keeping the heat medium-low and gradual whisking for your Cheesy Scalloped Potatoes sauce is essential.
