The sky’s the limit when it comes to sweet potatoes! Although there are so many different ways to prepare them, making sweet potato chips might just be my favorite. Perfect for when you are craving a salty snack, the air fryer will cook these chips to perfection in no time.

I love to have these chips on hand for lunches, big parties, or for an everyday snack. Serve them alongside an easy turkey sandwich, a wrap with chicken or set them out with an after school snack tray. The sweet potatoes provide a bright and pleasant flavor that is well balanced with the savory taste of salt and pepper. If you have an extra sweet potato lying around, this is a snack you must try!

Recipe FAQs

Do I need to soak the sweet potatoes before air frying?

Yes! Although sweet potatoes do not have as much starch as a regular potato, there is still a good amount. Soaking the sweet potatoes in cold water before air frying them will help remove some of that starch, allowing the chips to cook better and become as crispy as possible in the air fryer. You only need to soak them for about 30 minutes, but you can do longer than that if you have the time!

What kind of oil is best for sweet potato chips?

The purpose of the oil is to coat the sweet potatoes and help them crisp up, so using a high smoke point oil will offer you the best results! We use olive oil for the light and smooth taste, but you can also use avocado oil or sunflower oil.

Why aren’t my sweet potato chips crispy?

The biggest reason the sweet potato chips are not crispy is because there was too much moisture while cooking. To ensure you have crispy chips, pat the potatoes dry as much as you can after they soak in water and before seasoning them. Additionally, it’s important to avoid overcrowding the air fryer basket. If you try to cook too many chips at once then the moisture will get trapped and steam the potatoes instead of crisp them. After the potatoes are seasoned, place them in a single layer in the air fryer, and avoid overlapping as much as possible to allow the air to circulate. If you follow these steps, you will be left with crispy sweet potato chips every time!

How to Make Sweet Potato Chips in the Oven

If you don’t have an air fryer, no problem! You can still make these savory and crispy sweet potato chips. The preparation will be similar, but cook time and temperature will vary. Here are the steps to making these chips in the oven.

  1. Preheat your oven to 300°F. Line a baking sheet with parchment paper and set aside.
  2. Use a sharp knife or mandolin to thinly slice your sweet potatoes. 
  3. Add your sliced potatoes to a bowl of cold water and allow them to sit for 30 minutes.
  4. Transfer the potatoes to a kitchen towel and pat them dry. Once dried, toss them in the salt, pepper, and olive oil.
  5. Carefully place the potato slices on the baking sheet in a single layer, close to each other but not touching. 
  6. Cook the potato slices for 20-25 minutes until they are crispy and golden on the edges.
  7. Serve and enjoy! 

How to Store Sweet Potato Chips 

Any leftover sweet potato chips can be stored in an airtight container on the counter for up to 5 days. If you have a large gathering or party coming up, homemade sweet potato chips are the perfect side to bring. Since they save well for a few days, you can make them in advance to save on time! 

Expert Tips

  • You can either peel the sweet potatoes before slicing them or leave the skins on, whatever you prefer. 
  • If you’ve made chips before with russet potatoes, be aware that sweet potato chips will not crisp up the same but they will still be delightful.
  • Be sure to evenly coat the sweet potatoes in the oil so they cook evenly and become crispy! You can use tongs to toss the ingredients together in a bowl.
  • The thinner you slice your sweet potatoes the better they will crisp up and the quicker they will cook! If you have one, it is easiest to use a mandolin for even and thin slices. 
  • Feel free to add other seasonings if you want a different flavor! You can try garlic powder or chili powder to add more depth to the chips.
