Since buying my air-fryer (affiliate link), I’ve been keeping it on my counter and using it everyday. You may have seen my air fryer french frie recipe a few weeks ago, well so many of you have asked for sweet potato fries so I finally got around to it. I tested them out a few different temperatures to see which gave me perfect, crispy fries and here’s what I found. You can also bake them in the oven, see my oven baked sweet potatoes recipe.

How to make Crispy Sweet Potato Fries in the Air Fryer:

  • Start by making sure you cut them all the same size. This way, everything cooks at the same time, without burning, overcooking or under-cooking some.
  • Don’t overcrowd the basket. One small sweet potato will fit perfect but if it’s slightly larger, do them in batches. To make sure they are all hot at the same time, you can add the batches that are cooked back in the air fryer and heat them up 1 minute so everything is hot.
  • Don’t forget to turn them halfway. This is a must, the heat on the bottom is stronger than the top so turning is a must.
  • Open to test for doneness. Don’t be afraid to open the air fryer to check to see if they are done. If your fries are cut a little thicker, they will take longer to cook.
  • Bake at 400F. I found this gave me the crispest fry.

What is an air fryer?

An air fryer is a kitchen appliance that cooks by circulating hot air around food at high speed, which produces crispy food in a fraction of the time it would take in a conventional oven.

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.

A few more dishes I’ve made with the air fryer that I loved: Air Fryer Empanadas, Air Fryer Chicken Parmesan and Air Fryer Crispy Breaded Pork Chops. More recipes coming soon!

  1. Limp not crispy. I followed all the tips for crispy sweet potato fries and they never did crisp up. Cooked them 5 minutes longer and all they did was start to burn on he outside.  I have been using my air fryer for two years and this the first thing that failed.  I may try again by cooking at a lower temp then turning up to crisp. If that doesn’t work I give up. 

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

  3. 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.   

  4. Make sure you preheat the air fryer for 8 minutes it makes all the difference

  5. I couldnt get mine crispy!  They had a nice flavor. Not crispy

  6. 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! 

  7. 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!

  8. This made a nice quick side dish for dinner. Thanks!

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

  10. WE do not use OIL

  11. how do y’all cut the sweet potatoes, they are so hard to cut.

  12. 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!

  13. 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!  

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

  15.  I used my 7 in one- Power Air Fryer oven . I sprayed basket lightly with Pam Spray. I dunked a basting brush into less than a teaspoon of lite olive oil and lightly brushed the cut sweet potatoes. 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.

  16. Do I need to soak the potato, once sliced, before putting into the air fryer? Thanks!


  18. 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. 

    • 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 

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

  19. 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.

    • 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.

  20. 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!

  21. I followed this to a T and they did not come out crispy at all. They did get the black blotches here and there. I’ll keep tweaking. As an aside, the sugar in sweet potato can only “bloom” in temperatures up to 350 degrees according to Cook’s Illustrated. I always wondered why my baked sweet potatoes tasted bland, then I tried this and it’s true. So I’m wondering if it isn’t better to start them in the cold air fryer. Non the less, not crispy!


  23. 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 🙂

  24. Can potato pancakes be made in an air fryer? How would you do it?

  25. 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!

  26. Would you recommend any air fryer in particular, or are they mostly all the same? 

  27. 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.

  28. 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.

  29. 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?

  30. 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.

  31. 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!

  32. 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.

  33. Than you use frozen potatoes 

  34. 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 

  35. 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.

  36. Mine did not turn out crispy at all. Did I add too much oil? I used an extra large sweet potato so I upped the oil to 1 tablespoon

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

  38. Thanks for the recipe. they were really good!

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

  40. 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.

  41. I made these. They are super easy and very tasty. I substituted coconut oil for the olive oil.

  42. 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?

  43. Perfect and delicious. Just the right amount of crisp outside and creamy sweet potato inside.

  44. 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?

  45. 6 oz. sweet potato is 5 pts. So I only used 1 potato

  46. 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?

  47. Love this recipe! What do you use to cut the potatoes?

  48. 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 🙂

  49. 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.

  50. Just got an air fryer, these were great!

  51. 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!

  52. 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?

    • Cuisinart came out with one that’s larger. I have it on my wish list.

      • 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.

      • Mine doesn’t get hot at all. What brand did you get?

  53. 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.

    • Thanks,I don’t want to buy something else to put on the kitchen counter!

    • 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.

      • Thanks Gina I love my air fryer and really appreciate your air fryer recipes.

      • Hi Gina. Been following you for years before your cookbooks. Love your recipes. I’m not sure why, but when I made these, they didn’t get crispy.

      • Check out my tips in the post for “How to make Crispy Sweet Potato Fries in the Air Fryer”, above the recipe instructions.

    • 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?

  54. Hi Gina!
    What is the baking sheet sprayed with oil for?

  55. Have you tried this using white sweet potatoes?

  56. Sweet potato fries are my favorite so I love this idea!!

  57. Can you open the air fryer while it is still on to flip them?? I’ve always wondered! Thanks!!

  58. What do you suggest using to slice the fries evenly?
