How to make sweet potato chips in an air fryer

Ingredients

2 sweet potatoes
1 tsp olive oil

For the seasoning

1 tsp sweet smoked paprika or other seasonings such as Cajun seasoning, BBQ seasoning or garlic granules
½ tsp mixed herbs

Method

STEP 1

STEP 2
Cook, in batches, in a single layer in your air fryer basket at 180C for around 10-15 mins, until lightly golden, giving a little shake or toss after 5 mins. Once all the batches have cooked, return the fries to the air fryer, give it a good shake and cook for a further 1-2 mins to heat through.

Recipe tip

Any subsequent batches after the first one are likely to take less time to cook because the air fryer will be hotter to begin with. Keep a good eye on them after around 10 mins of cooking and check every minute or two.

Everyone loves sweet potato fries, so why not sweet potato chips? We think these are the perfect snacking chips to serve at a party or just to have as a snack in place of regular potato chips.

They are slightly sweet, super cripsy, and easy to make, especially if you have a mandolin to slice the sweet potatoes.

How to Make Air Fryer Sweet Potato Chips

Step One: Slice the Sweet Potatoes

Thinly slice the sweet potato (as thin as a regular potato chip), using a mandolin, if possible. Rinse the slices in cold water and pat dry. Some recipes encourage you to soak the slices for up to 20 minutes in water, but I don’t find that necessary. The outcome is the same, so save the time.

Step Two: Preheat the Air Fryer

Preheat the air fryer to 350°F (180°C). The reason to pre-heat is that the inside of the basket is already hot, so the chips cook more evenly. If you start from cold, it might take slightly longer to cook and they can become too browned in the extra time.

Step Three: Lightly Oil the Chips

Lightly coat the slices with olive oil or whatever oil spray you use. Sprinkle with salt. It doesn’t take much oil, just a very thin coating.

Step Four: Put Them in the Air Fryer

Lay them out in a single layer in the air fryer. If you can’t fit them all without stacking them, then cook in batches, rather than crowd the basket.

Step Five: Air Fryer

Air fry at 350°F for about 10 minutes. After 5 minutes, shake the basket and space out the chips again.

Watch the chips closely, checking every other minute, so they don’t burn and remove them as soon as a little bit of brown starts to appear on the chips. They might still be a little flexible; they’ll crisp as they cool.

Place on a cooling rack for a few minutes to cool and crisp up.

Tips for the Best Sweet Potato Crisps

You don’t have to spray the basket with cooking spray, since the potatoes have oil on them.

The cooking time will vary depending on the thickness of your slices. They can take anywhere from 8-12 minutes to finish cooking.

After 5 minutes start watching them closely, to avoid burning and remove as soon as some brown appears.

They might still be a little flexible in the middle, but they’ll crisp up when cooled. If you’re not sure, take one out of the basket and allow it to cool for 15 seconds to see if it crisps properly. If not, continue cooking.

You can somewhat overlap the slices in the basket, but don’t pile them on top of each other or they won’t cook properly. Work in batches instead.

Why Use an Air Fryer

An air fryer is an incredibly easy way to cook just about anything. You place the food in a fryer-style basket and hot air rapidly circulates all around the food, making the food crisp – much like deep-frying, but without the oil. You can cook anything you’d make in the oven.

What Oil & Oil Sprayer is Best for the Air Fryer?

The biggest issue most air fryer lovers face is finding the right oil and oil sprayer to use on food cooked in the air fryer. A fine mist of oil will help the entire piece of food crisp evenly, so it’s very important.

My personal preference is to use canola oil, extra virgin olive oil, or avocado oil. I use both a refillable spray bottle like the Evo one pictured below and non-propellant extra virgin olive oil, which has not harmful aerosols or chemicals.

Oven Cooking Instructions

If you don’t have an air fryer, you can bake the sweet potato fries. Here are the oven baking instructions.

Line a baking sheet with parchment paper or a silicon mat.
Lightly coat the sweet potato slices with olive oil and a sprinkle of salt. Lay them out in a single layer on the sheet.
Bake at 355°F for about 15-18 minutes. After about 13 minutes, start to watch the chips closely so they don’t burn and remove them as soon as a little bit of brown starts to appear on the chips. They might still be a little flexible; they’ll crisp as they cool.
Place on a cooling rack for a few minutes to cool and crisp up.
