What does au gratin mean?

The phrase au gratin literally means ‘by grating” in French. The crusty top of the dish is often achieved by adding grated cheese and/or breadcrumbs.

What you’ll need to make air fryer potatoes au gratin:

  • Air fryer
  • Mandoline (also spelled mandolin)-it is the perfect tool for slicing the potatoes very thin and in a consistent width. Mandolines save a lot of time.
  • Individual air fryer safe containers-ceramic, glass or silicone

Ingredients and some variations to try:

  • Potatoes: Red-skinned or Yukon Gold potatoes have thin skin so no peeling is necessary. These waxy potatoes hold their shape well. Sweet potatoes can be used in combination with other potatoes for a colorful combination. Russet (or baking) potatoes are more starchy and do not hold their shape as well and the dish may become mushy. Russet potatoes are not recommended for this dish.
  • Cheese: Sharp cheddar cheese works well in potatoes au gratin, either extra sharp or white cheddar. Gruyere is a traditional cheese to use and can be substituted instead of cheddar. Mozzarella, Colby Jack, Gouda, or Fontina can also be used. We recommend shredding the cheese from a block instead of using pre-shredded cheese for the cheesiest results.
  • Other ingredients needed are eggs, cream, and flour
