The holidays are here which means that it’s time to put together those fabulous menus! In addition to the traditional turkey, ham, cornbread dressing—I decided to add these delicious Three-Cheese Au Gratin Potatoes to our dinner menu!

This recipe uses not one, not two—but three different cheeses! That’s right, this creamy, cheesy, and irresistibly delicious, this classic dish gets a flavorful upgrade with the perfect trio of white sharp cheese, cheddar cheese, and gouda. 

What’s the Difference Between Au Gratin Potatoes & Scalloped Potatoes?

Scalloped potatoes and au gratin potatoes are both classic potato dishes, but they have distinct differences in terms of preparation, ingredients, and texture.

Scalloped potatoes are usually prepared with a simple bechamel sauce, made with flour, butter, and milk or cream, which is poured over the sliced potatoes. The dish is baked until the potatoes are tender, and the top is golden brown.

Similar to the scalloped potatoes, au gratin potatoes are thinly sliced and layered in a baking dish. Instead of a bechamel sauce, au gratin potatoes feature a rich and cheesy sauce made with cream or milk and grated cheese. The dish is usually topped with more cheese and baked until the top forms a golden, cheesy crust.

Whether you’re hosting a festive dinner or a cozy family gathering, Three-Cheese Au Gratin Potatoes are sure to become a holiday tradition. Happy holidays and happy feasting!

Author Beautiful Eats & Things


  • 6-7 medium russet potatoes thinly sliced into rounds
  • ½ yellow onion cut into slices

For the sauce:

  • 4 tablespoons salted butter
  • 1 ½ cups milk regular, skim or whole milk will work
  • ¼ cup all-purpose flour
  • 2 tablespoons green onions chopped
  • 1 teaspoon smoked paprika
  • 2 teaspoons garlic powder
  • ½ teaspoon dried rosemary
  • Salt/pepper to taste
  • ½ cup white sharp cheese shredded
  • ½ cup mild cheddar cheese shredded
  • ½ cup gouda shredded

For topping:

  • 1/3 cup white sharp cheese shredded
  • 1/3 cup mild cheddar cheese shredded
  • 1/3 cup gouda shredded


  • Preheat the oven to 375 degrees F. Spray an 8×12 baking dish with nonstick cooking spray or grease with oil.
  • Place sliced potatoes in 3-4 tight rows; making sure to leave enough space so the potato slices are slightly slanted. Add in onion slices in between the rows and on top of potatoes. Set aside.
  • To make the sauce: add in 4 tablespoons of butter, in a medium saucepan, and place over medium heat. Once butter is melted, whisk in the milk and flour milk, a little bit at a time, vigorously whisking away any lumps. Bring mixture to a simmer; it should be a similar consistency to creamy gravy.
  • Turn heat to low and stir in the seasonings and shredded cheeses. Taste and add more salt and pepper, if necessary.
  • Pour the sauce evenly over the potatoes and onions to cover them with foil. Bake for 45 minutes.
  • After 45 minutes, remove the foil, sprinkle the top of potatoes with the remaining cheeses and return to the oven and bake for 30 more minutes or until potatoes are done, and the top is nice and golden.
  • Remove from the oven and garnish with fresh parsley or green onions. Enjoy!
