Air Fryer Sweet Potato Fries

These are the best air fryer sweet potato fries! They are so crispy, flavorful and easy to make in the air fryer. Here I share two methods, a quick method that is delicious and a longer method that comes out perfectly crisp. Both taste great, feel free to use the method you prefer! Since you only need a little oil, they are also lighter and healthier than deep frying. One of my first recipes I ever made with my air fryer. Since then I have published two air fryer cookbooks and hundreds of air fryer recipes! Serve them with turkey burgers, or as a snack with your favorite dipping sauce.

Air fryer sweet potato fries

This is one of the first air fryer recipes I have ever shared. The fries are DELICIOUS but comments I get are that they’re not crispy. So I set out to tackle how to make a crispier air fryer sweet potato fries recipe and figured it out! It’s a few more steps, so I figured I would keep the quicker method if you don’t care (less crisp) and the crispier method that has more steps but made all in one batch.

Ingredients

  • Sweet potatoes, peeled and cut into 1/4 inch thick fries
  • Oil: Olive oil or any neutral tasting oil such as canola oil or avocado oil
  • Spices: Kosher salt or sea salt, garlic powder, black pepper and paprika

How To Make Air Fryer Sweet Potato Fries

Method 1: Quicker prep, needs to cook in batches, less crispy method.

  1. Preheat the air fryer.
  2. Spray the air fryer basket with oil.
  3. Peel each sweet potato and slice into even 1/4-inch thick planks, then into 1/4-inch thick fries.
  4. Toss fries with oil, salt, garlic powder, black pepper and paprika.
  5. Air fryer 380°F about 12 minutes in 2 or 3 batches, depending on the size of the basket without overcrowding, turning the fries or shaking the basket half way.
  6. Transfer sweet potato fries to large plate and serve right away with your favorite dipping sauce.

How To Make Crispy Sweet Potato Fries in Air Fryer

Method 2: Longer prep, cooks in one batch, crispier!

  1. Peel each sweet potato and slice into even 1/4-inch thick planks, then into 1/4-inch thick fries.
  2. Submerge sweet potatoes in large bowl of hot tap water and let them soak for 10 minutes. Drain potatoes, transfer to paper towel–lined rimmed baking sheet, and thoroughly pat dry.
  3. Toss sweet potatoes with 1 teaspoon of the oil in a clean, dry bowl, then transfer all to the air fryer basket.
  4. Place basket in air fryer (no need to preheat) and air fry 350F degrees 8 minutes, then shake and cook, 5 more minutes.
  5. Transfer sweet potatoes back to the empty bowl and toss with the remaining oil, salt and spices.
  6. Spray the basket with oil and return the sweet potatoes to the air fryer.
  7. Increase the temperature to 380F degrees, and cook until golden brown and crisp, about 4 to 5 minutes, shaking the basket halfway.
  8. Transfer sweet potato fries to large plate and serve right away with your favorite dipping sauce.

Variations

Play around with different spices for your fries. If you like them smokey, use smoked paprika. To make them spicy add some cayenne pepper. Or swap the seasoning for cajun seasoning. If you want them sweet, try sprinkling them with cinnamon or pumpkin spice.

Tips for Perfect Sweet Potato Fries in the air fryer:

  • Peel the potatoes or leave the skin on for more fiber.
  • Start by making sure you cut all the fries the same size. This way, everything cooks at the same time, without burning, overcooking or under-cooking some.
  • Don’t overcrowd the basket. If you’re using method 1, depending on the size of your air fryer basket and how many fries you’ll be making, cook the fries in batches in a single layer so there’s enough air flow for them to crisp up.
  • If cooking in batches, to make sure everything is hot at the same time once cooked you can pile all the batches back into the air fryer and heat them up 1 minute.
  • Turn halfway. Flipping your food halfway or shaking the basket a few times is a must for even cooking.
  • Open the basket to test for doneness. Don’t be afraid to open the air fryer to check to see if they are done. All air fryers will vary slightly. If your fries are cut thicker, they will take longer to cook. Adjust as needed.

Dipping Sauce Ideas

  • Ketchup: homemade or store bought
  • Garlic Mayo: Add crushed garlic to your favorite mayo.
  • Mayo-Ketchup: Combine equal parts ketchup and mayonnaise.
  • Garlic Sour Cream Dip: Combine sour cream and crushed garlic.
  • Honey Mustard
  • Tzatziki
  • Ranch Dressing

Is using an air fryer healthy?

  • Yes, it’s healthier that deep frying because you use less oil.
  • An air fryer is an excellent way to reduce a massive amount of fat and calories without sacrificing taste.
  • Since air fryers use air to cook food, it doesn’t require the extra calories that submerging food in oil would add.

  1. 5 stars for the crispier method. I cut them pretty small and they were crispy. The seasoning is nice, too. Will make again

  2. I think what’s missing is the wattage of the air fryer being used by the author. They range from 800 watts and up. The lower the wattage the slower it will take to cook. If your fries aren’t crisping up…chances are you have a low wattage Air Fryer. It’s not the recipe, it’s your tools.
    I went from a 900 watt to a 1400 watt….made a HUGE difference in cooking time and quality of food produced.

    I followed your recipe for crisper fries the longer prep and they did not come out crispy at all.

  4. are your picture of yam or sweet potatoes. Mine were pale white. The crispy version did not work for us. They were all limp. Not a flop because they were somewhat tasty but we like crisp. Is 350, 380 hot enough?

  5. Easy print using print button. Amazing recipe! used plan A and they were crisp and tasty and the very best we have ever had anywhere!

  6. Thanks! Finally, I got a mayo to work, using your immersion blender directions! I used a red balsamic vinegar and found it to be way too strong for my taste have to try something different next time.

    1. Because I was confused. This recipe was for the sweet potato Fries
      thaeycame out great I love them, thank you very much for the recipe

  7. Use enough oil to transfer the heat from the air fryer to the sweet potatoes, everyone! That is probably why those who didn’t experience crispiness (and got burning of the sugar in the sweet potatoes instead) had a problem. I brushed mine liberally with avocado oil and they came out perfect.

  8. Absolutely love this recipe. Light and crispy- so much healthier than deep frying …. Excellent recipe

    I followed the recipe…exactly…mine never got crispy… finally started to burn. Don’t know what to do about it. 

    1. More oil on the fries helps transfer the heat from the air fryer into the fries efficiently. What’s burning is the sugar in the fries so adding more oil helps prevent that.

  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 as I suspect they were a game-changer.  The fries were not soggy, nor crunchy, but a firm to slightly crispy outer portion of the fry while the inside was soft, yet thoroughly cooked.   

  11. I don’t know if it is because these folks are hungry or what- but man- some of you are grouchy.  These are amazing free recipes. You can tell a lot of work went into them. The fries are great and so are most things Skinny Taste.  Thanks Gina!

    These fries are crispy and delish! The tip of not overcrowding the pan is a game-changer for me. My air fryer fries were always limp and soggy until this recipe.
    Thanks, Gina!

  13. There’s no way to print this recipe without printing 50 pages of comments or all of the photos above.

    1. You can also just click, hold and highlight the text you want, then coy and paste into word document, then print

        It’s a little pricey but you will never need another. I love french fries and use it all the time. It is sturdy and easy to use. I can cut 5 potatoes in less than two minutes (this is an estimate as I have never actually timed myself)

  14. This was great and the hubby liked them, too! I accidentally used two TABLEspoons and luckily, only needed one sweet potato as we had great big salmon steaks to go with them. Thank you so much for sharing this!

  15. Delicious!  The crispiest, best tasting sweet potato fries I’ve ever made!  I made them in my Ninja 
    Foodi.  If yours come out soggy or limp, as mine always do when I put them in the oven, I think these are the two keys: first, cut them in small sticks, not too thick and most importantly- leave space between each fry in the basket.  I used 2 medium potatoes and it took about 5 batches, then I popped them all in together for a minute to heat up before serving.  They were great!

    Are you going to code the color codes for WW people. See you have the blue code but not the other colors with points.

    I applied sea salt /garlic to half and cinnamon to the other half. Put them in and tapped the preset  ‘French fry’ button. Crispy and delicious. I don’t know which one I liked better. Both were yummy! Crisp too. I am delighted.

  18. i TRIED MAKING THE SWEET POTATOES ONCE, THEY WERE SO GOOD NOW I MAKE THEM OFTEN. EASY AND VERY TASTY

  19. Like most reviewers said, these did not come out crispy at all. The only thing I changed were the spices. I used apple spice for a sweet treat.. but that shouldn’t have affected the overall crispiness. 

    1. Mine didn’t come out crispy at all.. Wondering what I did wrong? I used the Vremi air fryer and they really were just like roasted 

      1. If they are not crispy, cook them longer. Until they are cooked to your liking.  Do not overcrowd the pam

  20. These came out absolutely perfect! So simple. I have an oven type air fryer. So, I didn’t need the extra spray. Having 3 racks, I was able to cook them in batches. It’s incredible how crispy and “fried@ they came out.

    1. Can I ask what recipe did you use?  I followed the one above and have 3 racks too, but they didn’t come crispy at all.  Tasty but not crispy.

  21. I have an Power Air Fryer Oven Plus with a rotisserie basket. I’m sensitive to nightshades and seed spices , so I don’t use the paprika nor the black pepper.
    I preheated my air fryer oven for 8 minutes at 400F, and baked the sweet potato fries in a small batch in the rotisserie basket for 8 minutes. They were tasty, but not at all crispy. So I baked them two minutes longer. Then five more minutes. Still soft. Any suggestions?? I’d appreciate any help you could offer!

  22. Do you prebake your sweet potatoes at all? I bake mine a but and have good results in the fryer. But if I wouldn’t need to do that it would nice 🙂

  23. Hands down, the best sweet potato fries recipe I’ve ever tried. I didn’t change anything, and it took 3 batches to cook 1 large sweet potato. Thanks for the tip on warming it all up after the final batch was done!

  24. 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.
    Phillips Turbo Star Air Fryer was used.

    I thought the question of SWYPO mentality was a good one, so I looked it up, the answer in Whole30 101 states:

    Am I trying to exactly duplicate or recreate the poor food choice with “approved” ingredients, or am I merely looking for a healthier, more nutritious substitution for that food?

    In the case of Paleo desserts, it’s a straight swap. You’re desperately trying to duplicate the sweet treats you know and love in a way that’s still technically Paleo. But if you’re looking for a sandwich substitute, and you decide to use a lettuce leaf or a slice of roasted sweet potato, well, that’s a different story. Spaghetti squash for pasta, a portobello mushroom cap for a burger bun, or egg and spinach “muffins” for traditional muffins are all examples of perfectly healthy and appropriate substitutions during your Whole30. (Another tip: If you’re subbing something unhealthy with vegetables or high-quality meat, that’s almost certainly a thumbs-up.)

    Based on that thought, I think air frying sweet potato fries is a completely acceptable alternative to add to a healthier lifestyle.

    Hi,
    I am trying to decide if I can commit to the whole 30 and in doing some research read that this would fall under the “SWYPO” cheating rule because you are still eating a french fry. How is this whole 30 compliant?

    I killed a whole sweet potato. I followed the recipe to the letter. First batch – burned. Not crispy. Second batch – burned. Not crispy. Third batch, worse than the first two. I tried lowering the temperature, raising the temperature, cooking longer, cooking shorter. Nothing worked. I have a plate of burned wimpy sweet potato fries. The recipe is probably great. I guess I have an air fryer that never learned to make things crispy. Very frustrating and eventually too expensive if I keep having to toss the experiments.

  28. Really good! First two batches went twelve minutes, then ten for the second batch and then eight for the third. Made mostly as posted – used smoked paprika instead because that is what I had. 🙂 We will make these again!

  29. Oil frying isn’t unhealthy because of the oil, unless it’s so-called “vegetable oil”.
    What makes frying in general unhealthy is the high heat, which produces some harmful compounds, similar to grilling.
    Hopefully helpful.

  30. These look AWESOME!   Confused about the points though – when I plugged into WW it comes up as 7 Freestyle points?  Sure do like your 3 better lol.  Oh well, they look good enough to budget my points and give them a try!  Thanks for sharing the recipe 

  31. I’m curious too about how to get them crispier … but i just cooked them for about 15 min instead of 8. My first batch at 8 min were mushy and starchy.

  32. SO good!! They barely made it to the table as I was snacking on them while I waited for the other batch to finish. ?

  33. I tried this and followed the recipe but they didnt come out at all crispy. What could i have done wrong?

  34. Thanks for sharing this recipe. I have a question about the nutritional info you posted. When I enter the nutritional info you posted into my Weight Watcher calculator I get 7 points not 3 points. Am I doing something wrong?? I’ve only been doing WW for 6 weeks so that’s very possible.

  35. I want to make these for a group of five people so I would be tripling the recipe (at least 6 batches). What can I do to ensure that the fries are hot when served?

  36. I want to make these now for dinner later tonight. Can I just keep them on the counter in a tupperware or should I put them in the fridge?

  37. I can’t get the points to work out the way you do, Gina. Is it possible that the recipe is really supposed to have four servings, instead of two?

  38. OMG! I didn’t even know that there was a way for fries to actually be healthier. I am obsessed with fries but recently I have been trying to lose weight so I made a heartbreaking decision to stop eating them. Thanks to this website I saw there was way to make the food you love in a healthier way. I’m definitely telling my friends and family about this website. Will be making this tonight 🙂

    Love sweet potato fries and usually do in the oven. Found this recipe and had to try it out in my new air fryer. Delicious. I couldn’t find my sweet paprika so I used smoked which I love on sweet potato fries anyway. Will be making these again.

  40. Is the serving size supposed to be 1/2 a sweet potato? I can’t seem to get the points to work out given the nutrition information as posted. Thanks!

    1. I agree. I can’t get the WW points to come out to 3 for 1 serving of a whole potato. I’m coming up with 6 points if this recipe only makes 2 servings. I would have to do half a potato for the 3 points.

  41. All these air-fried recipes look so good, but it just doesn’t seem to be an appliance (yet) that is conducive or convenient for a busy family of 4+, given that everything has to be cooked in batches. Would you agree with this sentiment?

      1. My daughter bought one for me. Be sure to check warnings before you purchase. In my situation I figured the only place I could use it was on the back porch well away from any walls or upper cabinets. It gets too hot. I returned mine.

  42. Sheet pan, foil or silplat lining, cookie cooling rack. Oven on 450, better yet on convection bake. Voila! You have a way to make “french fries” just like an air fryer.  Easy to clean up, too.

      Yup, I have oven recipes here, but for everyone who keeps asking for air fryer recipes, this is the air fryer version. They come out crisper than the oven.

      Was wondering about this, too. Thanks for posting. I have all those items including the convection oven. About how long did you bake them for?

    1. I use a sharp knife. First I cut the potato into 1/4 inch thick slices, then I cut the slices into sticks.

      1. Well, I did it…I ordered an Air Fryer Toaster oven. I was going to just order an air fryer but my electric toaster oven is dying. I really really want to make these when it comes tomorrow. Thanks Gina!
