A dead ringer for their deep-fried counterparts, these crispy air fryer sweet potato fries have the irresistibility of your restaurant favorites but with a fraction of the oil (you can even make air fryer sweet potato fries with NO oil if you prefer). As with these baked Sweet Potato Fries and Sweet Potato Wedges, there’s ZERO deep frying, but the fries are still golden and crisp.

  • Fail-Proof Method. This recipe has all the tips you need to make sure your sweet potato fries don’t get soggy. (Nope, you don’t need to soak your sweet potato fries in water to get them crispy!)
  • Versatile. Easy enough to make as a snack, but made with a simple blend of seasonings that means they pair well with everything from Air Fryer Hamburgers to Grilled Chicken Sandwiches, and Instant Pot Chili. (Because these are the best air fryer sweet potato fries for making chili cheese fries!)

How to Make Air Fryer Sweet Potato Fries

The Ingredients

  • Sweet Potatoes. An excellent source of fiber, beta carotene, potassium, and more, sweet potatoes are a nutritional powerhouse. (Love ‘em? Be sure to check out these yummy oven Roasted Sweet Potatoes. Or try this Air Fryer Sweet Potato recipe if you don’t want fries.)

Market Swap

For healthy fries made with regular potatoes, check out my classic Air Fryer French Fries. Or for a different style of potato in the air fryer, try Air Fryer Baked Potato.

  • Olive Oil. 2 teaspoons per pound of sweet potato is all the oil you need to air fry them with success.

Substitution Tip!

  • For air fryer sweet potato fries no oil style, you can omit the oil. The fries will taste dryer—which is why I find using a little heart-healthy olive oil completely worth it—but you can still cook them with success.
  • You can also make these fries with canola oil, avocado oil, or peanut oil.
  • Seasonings. Keep it simple with salt and pepper or switch it up with your favorite seasoning blends. Garlic and paprika are our go-to’s; see below for more ideas.

The Directions

Recipe Variations

  • Cajun Sweet Potato Fries. Toss the fries in your favorite Cajun seasoning. Wait to season with salt to taste at the end, since Cajun seasoning blends typically already contain salt.
  • Spicy Sweet Potato Fries. Add 1/4 teaspoon cayenne pepper.
  • Parmesan Sweet Potato Fries. Top your air fried sweet potato fries with 1 to 2 tablespoons of freshly grated Parmesan.
  • Sweet Sweet Potato Fries. Toss the sweet potatoes with salt, a pinch of cinnamon, and a pinch of brown sugar.

Storage Tips

  • To Store. Refrigerate leftover sweet potato fries in an airtight container for up to 3 days.
  • To Reheat. For the best results, reheat leftover fries in the air fryer at 375 degrees F or in a 400 degrees F oven (I like to preheat the pan in the oven while it warms up); spread the fries in a single layer on the hot pan and recrisp. Air fryer fries reheat better than regular fries, since the lesser amount of oil prevents them from getting soggy.
  • To Freeze. Freeze fries in a single layer on a baking sheet until solid. Transfer to an airtight container or ziptop bag and freeze for up to 3 months. Reheat directly from frozen.

Meal Prep Tip

  • You also can use this recipe for frozen air fryer sweet potato fries. Keep a bag of your favorite brand in the freezer, then cook them in the air fryer instead of the oven. Or better yet, make a double or triple batch of these healthy homemade air fryer sweet potato fries and freeze them yourself.
  • To cook air fryer sweet potato fries from frozen. Coat your air fryer basket with nonstick spray and preheat the air fryer to 400 degrees F. Arrange the frozen sweet potato fries in a single layer in the basket (no need to toss them in oil). Bake for 10 to 15 minutes, turning the fries once about 6 minutes into the cook time.

What to Serve With Air Fryer Sweet Potato Fries

  • Chef Knife. This 8-inch chef knife is made from a single piece of steel and stays sharper for longer.
  • Cutting Board. A durable, non porous, polypropylene cutting board that doesn’t dull knives.
  • Air Fryer. This 5.5-quart Ninja air fryer preheats fast, thoroughly circulates air for prime crispiness, and cleans in a breeze.

Recipe Tips and Tricks

  • Season More Just After Cooking. To help the flavor pop, sprinkle the fries with a pinch of additional kosher salt immediately after removing them from the air fryer.
  • Banish Soggy Sweet Potato Fries. If your air fryer fries are soggy, it is likely because you over-crowded them in the basket. The sweet potatoes steam when crowded together, instead of air frying. For the best, most crispy results, cook the fries in a single layer so that the air has room to circulate.
  • Compromise a Little Bit for Faster Fries. Don’t have time for multiple batches? For decent but not quite as crispy results, you can cook up to two layers of sweet potato fries at once. Be sure the layers are not tightly packed and toss the fries in the basket often to promote even cooking.
  • Skip the Soaking. Some recipes call for soaking the sweet potatoes in water prior to cooking them to help remove some of the starch and make the fries more crispy. I’ve found this step didn’t make enough of a difference to be worth the effort. (Save soaking for Baked French Fries and Air Fryer Potato Wedges; regular potatoes have more starch than sweet potatoes, so soaking does make an important difference!)

These crispy air fryer sweet potato fries use only a little bit of oil and a handful of other pantry ingredients. An easy and healthy side!

Prep: 15 minutes
Cook: 15 minutes
Total: 40 minutes

Servings: 3 to 4 people

Ingredients
  


Instructions
 

  • Scrub the sweet potatoes and peel if desired (I leave the peels on). Cut the sweet potatoes in half lengthwise. Turn the halves cut-side down onto your cutting board, the slice each half lengthwise into 1/4-inch-wide strips (a mandoline is the best way to get even fries; watch your fingers!).
  • Turn the strips on their sides and cut each into 1/4-inch sticks. If the sticks are long, slice them in half crosswise so that your fries are about 3 to 4 inches. Transfer the fries to a large mixing bowl.
  • To keep the fries warm between batches, preheat the oven to 200°F and keep a baking sheet handy.
  • Drizzle the sweet potato fries with the oil and sprinkle with salt, garlic powder, paprika, and black pepper. Toss to coat, making sure the spices and oil are well distributed.
  • Preheat the air fryer to 375°F according to the manufacturer’s instructions. (For my air fryer, that is 3 minutes of preheat time).

FOR SOMEWHAT CRISPY, HIGHLY SATISFYING SWEET POTATO FRIES IN FEWER BATCHES:

  • Place the potatoes in the air fryer basket, doing no more than two layers (my air fryer is 5 1/2 quarts and I can add about 1/3 of the fries). Make sure the fries have plenty of room so that the air can circulate. Cook the sweet potato fries for 5 minutes.
  • Slide the basket out and use tongs to toss. Return to the air fryer and continue cooking for 5 to 7 additional minutes, until browned at the edges and crispy. The time can vary by several minutes based on your air fryer model and how done you like your fries. Check often during the last few minutes to make sure the fries don’t burn.

FOR SUPER CRISPY SWEET POTATO FRIES IN MORE BATCHES:

  • Place the sweet potatoes in just one layer in the basket, being careful that they do not overlap. Cook for 4 minutes, slide the basket out and flip, then continue cooking for 4 to 8 additional minutes, until the fries are as crispy as you would like (again, the time will vary based on your model, so check them several times and adjust as needed).
  • Remove the sweet potato fries to a baking sheet or a serving plate and immediately sprinkle with an additional pinch of kosher salt. Repeat with remaining sweet potatoes, keeping the cooked fries warm in the oven between batches as desired. Top with chives and enjoy!

Notes

  • *You can make the sweet potato fries with no oil if you prefer, but they will not be as crisp. Be sure to coat the fryer basket very well with nonstick spray.
  • In the recipe video, I am making a curry variation with salt, black pepper, and 1 tablespoon curry powder.
  • TO STORE: Refrigerate leftover sweet potato fries in an airtight container for up to 3 days.
  • TO REHEAT: For the best results, rewarm leftover fries in the air fryer at 375°F or in a 400°F oven (I like to preheat the pan in the oven while it warms up); spread the fries in a single layer on the hot pan and recrisp. Air fryer fries reheat better than regular fries, since the lesser amount of oil inherently prevents them from getting soggy.
  • TO FREEZE: Freeze fries in a single layer on a baking sheet until solid. Transfer to an airtight container or ziptop bag and freeze for up to 3 months. Reheat directly from frozen.

Frequently Asked Questions

Are Sweet Potato Fries Actually Healthy?

Traditional sweet potato fries kind of negate all of the health benefits of sweet potatoes with the deep frying and salt. Air fryer sweet potato fries are made with only a small amount of oil for fewer calories and you control the amount of sodium, which means: yes, they are actually healthy! You can read more about the benefits of sweet potatoes here.

Why Are My Sweet Potato Fries Burning in the Air Fryer?

If you cut your sweet potato fries in uneven sizes (i.e., some much thinner than others), the smaller fries may start to burn while the thicker fries are still cooking. If all of the fries are burning, the temperature of your air fryer is too high or the fries have been cooking for too long.

How Do You Fix Mushy Sweet Potato Fries?

Unfortunately, once your fries are mushy, there’s not much you can do to crisp them up. If the fries are packed into the basket too tightly, they will steam and soften.

    1. Hi Mikel! I’m so sorry to hear that. It’s so hard to know what went wrong without being in the kitchen with you. Did you preheat your air fryer? If you have a model that doesn’t need to be preheated, maybe try setting it a 375 degrees F for a few minutes to it’s hot when you put the fries in. Hope this helps!

  1. Very good and fast only thing is it never said in the article how long to cook the sweet potato fries when they are fresh5 stars

    1. Hi Brandi! So glad you enjoyed the recipe! Did you read all of the instructions in the recipe card? This recipe is a recipe for fresh sweet potatoes. I do add some notes in the post helping you cook them if you decide to use store bought frozen sweet potatoes. Hope this helps!

  2. I had some fresh sweet potatoes from a local farm and found this recipe and loved the seasoning that it called for.

    I used garlic salt, salt and pepper, and paprika and 1 tablespoon of olive oil!

    I was using a consori countertop oven/air fryer/ and toaster all in one so I needed to cook them around 15 minutes on the air fryer setting.

    They turned out perfect!5 stars

  3. I’m so bummed. I just got my air fryer and this was the first recipe I wanted to try. Mine came out soggy. I have 7.5qt nuwave fryer. Cooked them for 15 minutes at 375 and still weren’t crispy.

    1. Hi Pete, I’m sorry to hear that you had trouble with the recipe. The method and timing has worked well for myself (and others) but I know how frustrating it can be to try a new recipe and not have it work out, so I really wish you would’ve enjoyed it!

  4. I tried these for the first time last night, and they were a big hit with my family. The amount of seasoning was perfect and they were very crispy. Thanks for sharing this recipe. We are definitely going to use it often!5 stars

  5. I lengthened the time because I cut my sweet potatoes a little bigger but otherwise followed the recipe and had perfect fries. Simple and delicious!5 stars

  6. This was my first time making sweet potato fries in the air fryer and it turns out perfect! I added some cayenne pepper to mine and it was awesome.5 stars

  7. Everyone loved these! Great balance of seasoning, and super easy. I’m not a big fan of sweet potatoes but I like this. I made a garlic mayo dip along with it.5 stars

  8. I loved this recipe. It was quick and easy. I will make a few adjustments next time. I am new to the air fryer and mine weren’t quite as crunchy as I would have liked but they were delicious. The flavor was good.5 stars

  9. Mine came out crispy and delicious. I sprayed potatoes with Avocado oil and lots of seasonings. I shook the basket a lot and in 15 min they were done. Btw I used a Phillips Turbo Star Air Fryer.5 stars

  10. I used this recipe to test out my air fryer that I just bought today. I am a complete newbie to this. They came out wonderful! I followed all the helpful pointers in the recipe, which I am very thankful for.5 stars
