Air Fryer Sweet Potato Chips

Salty snacks can be an addiction for me, so I try to avoid the chip aisle in the grocery store. If I buy them, I’ll eat them so it’s best to leave the temptation on the grocer’s shelf!

That being said, I occasionally end up with a bag of potato chips in my cart, but since I got my air fryer making my own chips for snacking is a real treat with less guilt since I know exactly what ingredients go into my sweet potato chips.

How to Cook Crispy Sweet Potato Chips in an Air Fryer

It took a bit of recipe testing before getting the cripsy results that I wanted from air frying sweet potato chips. Here are a few things that I learned:

  • Make sure the sweet potatoes are sliced thinly and evenly. Sweet potatoes are harder to slice than a regular Idaho potato, so it’s important to use the right tools in order to get even slices. You want slices that are about 1/8-inch thick. It’s hard to do that with a chef’s knife, but a mandolin works well or I find this OXO Grate and Slice Set easy to use.
  • TIP: Always use the food holder to guard your fingers when using a mandolin to slice foods — the blades are super sharp!
  • Slices that are too thick will be chewy and not crispy.
  • Soaking sweet potato slices in ice water for 30 minutes will remove some of the starch and will also help keep them from sticking together when cooking.
  • Dry the sweet potatoes thoroughly by patting with paper towels. The drier the slices, the crispier they will become as they cook.
  • Don’t overcrowd the air fryer basket. Place slices in a single layer for more even cooking.
  • Only toss as many sweet potato slices as will fit in your air fryer basket in a single layer with the oil and seasoning. If the slices sit in the oil waiting to cook, they will become soggy.

Air Fryer Cooking FAQs

What is an air fryer?

An air fryer works sort of like a convection oven in that it uses convection heating and a fan to circulate air around your food. Like a deep fryer, the air fryer is a counter top appliance with a basket for the food, only you cook without hot oil.

Is cooking with an air fryer healthy?

Any time you can reduce the amount of oil and fats you add to foods when cooking you’ll have a more nutritious outcome. According to the Cleveland Clinic, most people reduce their calorie intake by 70 to 80 percent, on average, when using air fryers instead of deep frying.

Can you use cooking spray in an air fryer?\

Cooking spray can cause a build up and damage the air fryer non-stick basket.

Do you use oil in an air fryer?

There’s no need to use oil at all when cooking with an air fryer, however tossing some foods in a little amount of oil before air frying will add more flavor.

Do air fryers cook faster?

Typically, air fryers do cook faster, but if you’re cooking for a large number of people overall it may take longer due to the air fryer basket capacity and cooking in batches.

Can you cook frozen foods in an air fryer?

Absolutely, but remember a lot of convenience frozen foods are fried beforehand so you won’t gain the health benefits of cooking with less oil by cooking frozen fried foods in the air fryer.

Air Fryer Sweet Potato Chips Recipe

When you make this sweet potato chips air fryer recipe in your appliance, you may want to experiment with the cooking temperature and times since there may be variances in different air fryer models. I found that cooking at a lower temperature was better because at a higher temperature the chips tended to burn quickly at the end of cooking.

Cook the sweet potato chips for just a few minutes then shake the basket. Continue cooking, shaking and checking at short intervals until the chips are the way you like them.
