Air Fryer Au Gratin Potatoes

These simple Air Fryer Au Gratin Potatoes are perfectly portioned potatoes that cook up hot and bubbly in just minutes! 

I love to serve these cheesy potatoes with my Juicy Oven Baked Chicken Breast and a side of steamed green beans for a complete meal.

The beautiful thing about these potatoes is that you can quickly prepare them in the air fryer.

Since they are individually portioned out into 1 cup servings, they quickly cook and become bubbly throughout with a gorgeously browned top.

Ingredients Needed:

Here’s the basic list of ingredients you’ll need in order to make these potatoes au gratin in the air fryer. As always, you can find the printable recipe card located below.

• Butter   – salted
• All Purpose Flour
• Green Onions
• Garlic
• Milk  – I used whole milk, but you can use 2%
• Mild Cheddar Cheese   – shredded
• Frozen Shredded Potatoes – hash brown potatoes or frozen diced potatoes will work too

How To Make Au Gratin Potatoes In The Air Fryer

You’ll start off by making a simple roux with the butter and flour to create the creamy cheese sauce for the au gratin potatoes. Don’t get intimidated by this process, it’s actually quite simple.

MAKE A ROUX   Start by melting the butter in a skillet over medium heat. Once it’s melted whisk in the all purpose flour until it’s evenly incorporated and cook about 1 minute. Gradually pour in the milk, while continuing to whisk the mixture, until it’s all incorporated and smooth.

ADD CHEESE   Stir in the garlic and green onions and cook until fragrant, about 1 minute, then add in the cheese, salt and pepper. Stir until combined and smooth again.

STIR IN POTATOES   Once the cheese sauce has been made, stir in the frozen potatoes.

DIVIDE INTO CUPS   Coat the glass cups with non-stick spray and divide the potato mixture between the cups. Place the cups in the basket of your air fryer and cook for just 9 to 10 minutes, until the potatoes are bubbly throughout!
