Easy Au Gratin Potatoes in the Air Fryer!

  • The versatile air fryer makes classic cheesy au gratin potatoes with soup and sour cream instead of building a sauce from scratch! It’s a great starter recipe for Ninja, Vortex, or Cosori newcomers!
  • It’s the perfect holiday side dish that doesn’t take long to make and tastes just like a freshly baked dish without long oven times!
  • Au gratin or scalloped? Both contain slices of potatoes baked in a creamy sauce, but au gratin (French for grated – as in the topping) features an extra layer of cheese topping or breadcrumbs.
  • For a quick and easy weeknight dinner, use the air fryer to make au gratin potatoes and serve them all week long! Pair them with an air fryer steak or meatloaf.

Ingredients & Variations

POTATOES: Choose red-skinned or Yukon gold potatoes for their thin skin (no peeling required!) and starchy texture. Sweet potatoes can be used as well, or a colorful combination of the two!

CHEESE: Mild-flavored potatoes are the perfect partner to sharp cheddar cheese! Go for extra sharp cheddar or white cheddar for a cleaner look. For best results, shred cheddar from a block instead of buying pre-made for the cheesiest results!

Pro Tips for Perfect Potatoes

  • Always slice potatoes in the same width so they cook at the same rate.
  • A mandoline is a perfect tool for uber-thin slices of fruits and vegetables and they save a ton of time!
  • Frozen scalloped potatoes can be used, too! Simply add extra minutes to the cooking time!
