Sweet Potato Chips

Iโ€™ve been on a kick lately โ€“ a homemade snack kick. And let me tell you, this recipe has been on a weekly rotation in my kitchen. Itโ€™s nearly impossible to stay out of these chips when you know theyโ€™re in the pantry! The thing is, I love munching on sweet potato chips instead of classic store-bought potato chips. Essentially, theyโ€™re just sliced sweet potatoes with a bold blend of seasonings that get crunchy in the oven. No additives and no deep frying โ€“ just everything about chips that you like without the stuff you donโ€™t! Plus, theyโ€™re loaded with nutrients, so you can really feel good about enjoying this wholesome snack.

Why arenโ€™t my chips geting crispy?

There could be multiple culprits. First off, make sure the chips are cut into even thin slices. Thick slices can turn soft, not crispy. Second, donโ€™t overcrowd the air fryer basket or baking sheet. Overlapping traps moisture and prevents crisping. Finally, let them cool all the way off! When theyโ€™re still warm, they wonโ€™t be as crunchy. 

How to Make Sweet Potato Chips

Air Fryer:

  • Prepare. Preheat the air fryer to 325ยฐF.  
  • Add the slices to the basket. Spray the basket with nonstick spray, then arrange the potatoes in a single layer in the basket, working in batches so they donโ€™t overlap. 
  • Air fry. Fry in five minute increments, flipping each time until crispy and golden. 
  • Let them cool. Remove the chips and let them cool off.  
  • Repeat. Repeat the process with the remaining slices.  

Oven:

  • Prepare. Preheat the oven to 325ยฐF and line two baking sheets with parchment paper. 
  • Lay on baking sheets. Arrange the slices in a single layer on the baking sheets so they donโ€™t overlap. 
  • Bake. Bake for 20-25 minutes, flipping every 5 minutes, until they are crisp and lightly browned. 
  • Repeat. Repeat with the remaining slices. 
  • Cool. Let the chips cool for a few minutes before serving, garnishing with minced parsley and ranch.

Storing Sweet Potato Chips

You can store your chips in an airtight container at room temperature for up to 2 days. I donโ€™t recommend freezing these chips. You can reheat them in the oven or air fryer, but I think theyโ€™re best at room temperature! 

Ingredient Notes

  • Sweet Potatoes – I like to use sweet potatoes that arenโ€™t very round. Long, skinny sweet potatoes work best for this recipe. 
  • Olive Oil – Avocado oil is a good substitute. Be careful not to overdo it โ€“ too much oil can make the chips soggy. A light coating is all they need. 
  • Brown Sugar – This adds a subtle caramelized element to the chips that balances perfectly with the cajun seasoning. 
  • Cajun Seasoning – I prefer to use a no-salt blend. If yours has salt, you may want to omit the additional salt called for. 
  • Garlic Powder – Donโ€™t try to show off by using fresh garlic instead of garlic powder! Itโ€™ll burn and have the wrong texture. 
  • Salt – Kosher or flaky sea salt is the best.
