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 crispy, and easy to make, especially if you have a mandolin to slice the sweet potatoes.
Ingredients You’ll Need
- Sweet potato – This recipe only calls for one sweet potato, unpeeled and washed.
- Olive oil – Olive oil is our go-to but you can use whatever oil spray you like.
- Salt – A light sprinkling of fine salt is all that is needed.
Equipment Information
- Air fryer: I use this 4-quart basket-style air fryer. It’s large enough to fit a meal for 4-6. But some things need more space in the air fryer basket, so they cook evenly.
- Kitchen tongs: It’s very easy to remove food from your air fryer with kitchen tongs. I use these kitchen tongs that are silicon coated so they don’t scratch the interior.
- Mandolin – A mandolin will help you thinly slice the sweet potato (as thin as a regular potato chip).
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.
Variations
These chips are delicious with just a sprinkle of salt but just think about all of the possibilities! Try sprinkling one of these onto the freshly cooked sweet potato chips.
- Parmesan cheese
- Cinnamon sugar
- Cajun seasoning
- Carne asada rub
- Smoked paprika
- Brewer’s yeast
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 chips. 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.
How to Store Leftovers
To store leftover sweet potato chips, allow them to cool completely and then place them in an airtight container or resealable plastic bag. This will protect them from moisture which can make them go stale or chewy.
Store them in a cool, dry place, such as a pantry or cupboard, for up to 5 days. For even longer storage, you can freeze the chips for up to 2 months in an airtight container. Be sure to label the container with the date so you can keep track of the shelf life.
To thaw frozen sweet potato chips, allow them to come to room temperature before reheating them in the oven or air fryer to regain their crispiness.
Frequently Asked Questions
Why are my sweet potato chips not crispy in the air fryer?
Its possible that you have overcrowded the basket. The chips need to be in a single layer so that they can get full air circulating around them. You may also need to spray them with another mist of oil.
Do you have to soak sweet potatoes in water before air frying?
This recipe calls for the sweet potato slices to be rinsed in water and then dried before air frying. That will remove some of the starch so that they don’t turn an off color and it also helps them crisp up.
Why are my sweet potato chips burning in the air fryer?
If your chips are burning the temperature in your air fryer needs to be decreased. Too high of a temp will make them burn before they are fully cooked.
