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.

Which Air Fryer Is Best?

I get this question a lot whenever I post a new air fryer recipe. I personally like the Gourmia 7 quart Air Fryer.

You can usually find it at Costco for a good deal, but it’s also available on Amazon too.

For this particular recipe we’re using the basket style air fryer, which is what I prefer as opposed to the toaster oven style. I believe this recipe would work fine in either style.

Air Fryer Safe Containers

In order to be able to cook these potatoes in the air fryer, the cups used need to be air fryer safe.

You could use either glass or ceramic or even silicone containers in the air fryer. Please do not use plastic in the air fryer, as this will melt and cause a mess.

I found these fantastic 1 cup Pyrex glass containers that come with a lid for easy storage. They work perfectly for this recipe.

Make Ahead Au Gratin Potatoes

The best part about this recipe is that you can easily prepare these potatoes, pop a lid on them before cooking and place them in the fridge for up to 4 days!

In order to cook, just remove the lid, place it in your air fryer and cook!

This makes it great for small batch cooking, or when you want to eat some cheesy potatoes but don’t want to prepare a whole casserole!

FAQs

Why won t my potatoes cook in the air fryer? ›

If you're consistently stumped with why your potatoes aren't crisping up, there's a good chance that you're overfilling your air fryer. There's a reason people say “less is more”. Overfilling your air fryer can stop the air from circulating properly and can cause the potatoes to cook unevenly.

How long does it take for a potato to get soft in the air fryer? ›

Preheat an air fryer to 400 degrees F (200 degrees C). Rub potatoes with olive oil and season with salt, pepper, garlic powder, and parsley. Place potatoes in the air fryer basket. Cook in the preheated air fryer until potatoes are soft, 40 to 50 minutes, depending on potato size.

Do I need to microwave potatoes before air frying? ›

The size of the potato and model of airfryer may effect the cooking time. To speed up the cooking time, you can microwave on high for 8-10 mins before airfrying (check after 15-20 mins). When ready, the skin should be crisp and the inside tender and fluffy.

Why soak potatoes in water before air frying? ›

Soaking the potatoes does something magical with the starches—it helps achieve the coveted French fry crispiness and prevents the fries from sticking together.

Are potatoes better in oven or air fryer? ›

While a baked potato made in the oven is undeniably delightful, a baked potato is even more scrumptious when it's made in an air fryer. The concentrated heat and fan in the air fryer crisps the skin of the potato to perfection while also creating light, fluffy insides, ready to be topped any way your heart desires.

Why are people getting rid of air fryers? ›

A: The main reasons to cut the potatoes and pre-soak in water are: To allow the excess starches and sugars to be removed from the outer surface of the fry strips AND to keep the potatoes from browning prematurely from exposure to air. Covering in water helps the potato from turning a dark color.

What happens if you don't boil potatoes before frying? ›

Do I need to boil my potatoes first? Trust us: You seriously don't need to boil these spuds (or pre-cook them at all) before pan-frying. Slicing them thin allows them to cook through in the same amount of time that they need to get brown and crispy on the outside.

Why did my au gratin potatoes turn GREY? ›

Why are my au gratin potatoes greasy? ›

Too much cheese will break and become greasy, but a small amount of Parmesan adds a salty tang, while some Gruyere puts nuttiness into play.
