The Best cheesy potatoes au gratin recipe

I’ve been making cheesy potatoes au gratin for my family for years, and it’s always a crowd-pleaser. The dish originated in France, where it’s known as pommes de terre au gratin, but I like to think of it as a comfort food classic. The combination of creamy cheese, tender potatoes, and crispy top is pure bliss.

And the best part? It’s ridiculously easy to make. All you need is some high-quality cheese, potatoes, cream, and a few other pantry staples.

I like to use a mix of cheddar and Parmesan for a rich, tangy flavor. The key to this recipe is to use high-quality ingredients and to cook the potatoes until they’re tender but still hold their shape. Then you can top them with the cheesy goodness and bake until golden brown.

It’s perfect for a weeknight dinner or a special occasion like Thanksgiving or Christmas. My kids love it when I make this for dinner because it’s like a special treat. And let’s be real – who doesn’t love a good cheese sauce?

This recipe is also surprisingly healthy considering how rich it tastes. The potatoes are packed with fiber and vitamins, while the cheese provides calcium and protein. And if you’re feeling fancy, you can even add some chopped herbs or spices to give it an extra boost of flavor.

🥘Ingredients

For the Potatoes

2 pounds russet potatoes, peeled and sliced 1/8 inch thick
2 tablespoons unsalted butter, softened
1 clove garlic, halved

For the Cheese Sauce

3 tablespoons unsalted butter
3 tablespoons all-purpose flour
2 cups whole milk, warmed
1 teaspoon salt
1/2 teaspoon black pepper
1/4 teaspoon ground nutmeg
2 cups shredded sharp cheddar cheese
1/2 cup grated Parmesan cheese

For Topping

1/2 cup shredded sharp cheddar cheese
2 tablespoons grated Parmesan cheese
1 tablespoon chopped fresh parsley (optional)

👨‍🍳Directions

1Preheat the oven to 375°F.
2Rub the inside of an 8×8 inch baking dish with the cut side of a garlic clove, then spread 2 tablespoons of softened butter evenly over the bottom and sides of the dish.
3In a medium saucepan over medium heat, melt 3 tablespoons of butter.
4Whisk in the flour and cook for 1 minute, stirring constantly, until the mixture is bubbly and golden.
5Gradually pour in the warm milk while whisking continuously to prevent lumps.
6Bring the sauce to a gentle simmer, then reduce heat to low and cook for 2 to 3 minutes, stirring often, until the sauce thickens enough to coat the back of a spoon.
7Remove the saucepan from heat.
8Stir in 2 cups of shredded cheddar cheese and 1/2 cup of Parmesan cheese until completely melted and smooth.
9Season with salt, pepper, and nutmeg, then set aside.
10Arrange a single layer of potato slices in the prepared baking dish, slightly overlapping them.
11Pour about one-third of the cheese sauce over the potatoes, spreading it evenly with a spatula.
12Repeat the layering process two more times, using all remaining potatoes and sauce.
13Press down gently on the top layer to ensure the potatoes are submerged in the sauce.
14Cover the dish tightly with aluminum foil and bake for 40 minutes.
15The potatoes should be tender when pierced with a knife.
16Remove the foil, sprinkle the remaining 1/2 cup cheddar and 2 tablespoons Parmesan on top, and bake uncovered for 10 to 15 minutes more until the top is golden brown and bubbly.
17Let the dish rest for 5 to 10 minutes before serving.
18Garnish with chopped parsley if desired.
