    If you're looking for an easy holiday side dish, try these creamy, cheesy potatoes au gratin. They take about an hour to bake in a regular oven but only about 20 minutes in the air fryer!

    We just bought the Instant Pot Omni Plus, and it's huge! Most of my air fryer recipes were made in the smaller Vortex. But, I wanted an air fryer that was big enough to make family-sized meals, and this one delivers!

    The very first thing I made in my new air fryer was this easy, cheesy scalloped potato recipe. It usually takes about an hour in the oven, but this quick gratin recipe only takes 20 minutes in the air fryer! Amazing!

    The Difference Between Scalloped Potatoes and Au Gratin Potatoes

    In short -- It's all about the cheese. Both baked potato dishes are made with thinly sliced potatoes and cream or milk.

    But, au gratin potatoes have shredded cheese between the layers and on top, which forms a tasty crust as it bakes. Scalloped potatoes traditionally don't have cheese.

    So if you want to call this delicious side dish cheesy scalloped potatoes, that's totally fine.

    The Best Potatoes to use for Au Gratin

    I use Yukon Gold for gratins and most potato dishes because they hold they hold their shape well, and you don't have to peel them. Russets work well in this recipe, too.

    Best Cheese for Au Gratin

    Gruyere is traditional, but almost any shredded cheese will work. I used a combination of sharp cheddar for flavor and Colby Jack for extra creaminess. You could also add some grated Parmesan to the top.

    How to Make Quick Gratin Potatoes in the Air Fryer Oven

    First, you want to slice the potatoes as thin as possible -- around ⅛ inch or ¼, but not more. I recommend using a mandoline slicer - just be careful while you slice them.

    To make this recipe come together quickly, I don't make a cheese sauce with flour. Some will say you should to prevent the sauce from separating or curdling, but I've never had that happen.

    I don't mix the potatoes and cream together. Just butter the dish, and start layering the potatoes.

    The ends will overlap a little, but don't stack the potatoes on top of each other. Then, season the potatoes, and add a little cream and cheese.

    Repeat the process until you have 4 layers of potatoes. Then, finish with a layer of cheese -- you can add more here if you want.

    Pour the remaining cream over the potatoes, and dot with a little butter. Did I mention this is not a light dish?

    There's no need to cover the dish. Just pop the potatoes into your air fryer oven, and bake at 350 degrees.

    As the potatoes au gratin bake, the cheese forms a nice crispy crust on top. If you want, you can add more cheese to the top right before it's done.

    How Long to Bake au Gratin Potatoes in an Air Fryer

    Every air fryer is different, but these cheesy potatoes were perfectly cooked and fork tender after just 20 minutes. You'll want to keep an eye on them as they cook.

    Let the potatoes rest for about 5 minutes after baking. This helps the cream sauce thicken up, and it will continue to thicken up as it cools down.

      Just double checking the temperature. When you say 350 degrees, are you talking Fahrenheit. I am in Australia and my air fryer is in Celsius and max temp is 200.

      Very new to air frying and looking forward to cooking this tomorrow night.

        Yes -- Sorry about that. I'm in the States, so it's 350 degrees Fahrenheit. Hope you like the potatoes!
