A crispy sweet potato chip made in the oven? Is that even possible? Yes, yes, it is! The secret is in the thickness of the chip and the elevation from the cooling rack. Thin slices of sweet potatoes and the oven’s low temperature produce a baked chip that is crunchy, delicious, and nutritious.  Sweet potatoes are a great source of fiber, potassium, and vitamins A and C. They’re also a good source of antioxidants. So why not ditch the processed snacks and make your own sweet potato chips instead? Let’s get started!

Ingredients to make sweet potato chips

How to make sweet potato chips in the oven

The hardest part of making sweet potato chips in the oven is waiting for them to crisp up, and even that doesn’t take much time. After you slice, the oven does all the work!

Thinly slice the Sweet Potato

  1. Using a sharp knife, cut the sweet potatoes into thin, even slices.
  2. Transfer the sweet potato slices to a large bowl and toss them with the oil and salt.

How to Bake Sweet Potato Chips

  1. Arrange in a single layer on the cooling rack.
  2. Bake until curling and browning around the edges. Let cool completely on the cooling rack.

Tips for making the best baked sweet potato chips

  1. Use a mandoline for even slicing. The more even your chips are cut, the more evenly they’ll bake and crisp up! Don’t run out and buy one, but if you own one, this is a great time to use it!
  2. Turn on the convection. Additional air circulation really helps the chips to crisp up. If your oven has a convection setting, drop the temperature to 275°F and turn on the convection!
  3. Choose thin sweet potatoes. A thinner sweet potato will yield slices with a smaller diameter, which will dry out and crisp up easier in the oven than slices with a larger diameter. In this case, bigger is not better!
  4. Go for organic. If you have the option to purchase organic sweet potatoes, go for it! Organic sweet potatoes are grown without the use of synthetic pesticides, so you can rest assured that your chips will be free of any nasty chemicals.
  • Try other root vegetables. You can make chips from regular potatoes, carrots, parsnips, and beets too! This recipe works well for all of them. The time may need to be adjusted some, but in general, the process and cooking temp are the same.
  • Experiment with seasoning. Try adding herbs and spices like smoked paprika, garlic powder, or chili powder for a flavor twist on the classic salted sweet potato chips.
  • Try using a flavored oil. A flavor-infused oil like garlic or chili oil will add a punch of flavor to your chips.

What to serve with your crispy sweet potato chips

How to store sweet potato chips

Once your chips are baked and cooled, the best way to store them is in an airtight container. They will last for about 4-5 days when stored this way.

Frequently asked questions

Can I use an air fryer to make these sweet potato chips?

Absolutely, if you have an air fryer, you can use it for a smaller batch of sweet potato chips. Arrange the sweet potato slices in the air fryer basket in a single layer and fry at 325°F for 10-12 minutes, stopping every 5 minutes to rearrange the chips in a single even layer.

Do I have to use oil?

No, although your chips may not get as crispy. The oil also adds a little flavor. If you choose not to add oil, you may need to lower the oven temp to 275°F and increase the cooking time for a longer, low and slow cook. Essentially we want the oven to dehydrate the chips, so low and slow is the way to go.

Do I have to leave the skin on?

If you want to, you can peel your sweet potato. I like to leave the skin. Sweet potato skin is not only edible but packed with nutrition. Leaving the skin adds flavor, texture, and a nice contrast of color!

  • 1 sweet potato scrubbed
  • 1 tablespoon olive oil
  • ¼ teaspoon salt


  • Preheat the oven to 300°F. Prepare a baking sheet by fitting it with a large cooling rack.
  • Using a sharp knife, cut the sweet potatoes into thin, even slices, no more than ⅛-inch thick. Transfer the sweet potato slices to a large bowl and toss with the oil and salt. Arrange in a single layer on the cooling rack (some slight overlap is ok).
  • Bake for 30-40 minutes, flipping every ten minutes, or until curling and browning around the edges. Let cool completely on the cooling rack, then store in an airtight container.


Tip: Use a mandolin for even, thin slices. This ensures that each and every chip is the same thickness, so you don’t end up with a few crispy chips and a handful of soggy ones.

  2. Carolyn says:

    I tried these today and love them! I didn’t slice them that evenly so I would use my mandolin next time.
    Great healthy snack!

    1. Yumna J. says:

      So glad you enjoyed the chips, Carolyn! A mandolin really does help get that even cook and crisp throughout the entire chip. You’ll have to let me know if you feel like there is a difference when you make them again.
