Do you know about the Air Fryer? It’s a relatively new cooking gadget that gives results similar to frying without having to cook the food in lots of oil. My sister Laurel is the one who told me about Air Fryers, and I mulled it over for a while before I bought one. Air Fryer Spicy Sweet Potato Fries  were the first thing I made in my new Air Fryer, and they were a winner! I love the ease of making fried food in the air fryer, but if you’re not interested in another cooking gadget just make my Spicy Baked Sweet Potato Fries!

Sweet Potato fries never get as crisp as the ones made from white potatoes, but the Air Fryer sweet potato fries are definitely crisper than oven-baked sweet potato fries. It took us a couple of tries to get the timing and temperature right, and you need to be careful to turn the fries halfway through the cooking time (or the ones on the bottom will get too dark), but otherwise the hardest thing about making Air Fryer sweet potato fries is cutting up the sweet potatoes! And if you want to use those pre-cut sweet potato fries that show up this time of year, no judgement from me, but those will probably cook a bit faster.

And by the way, these are orange skinned sweet potatoes and not yams! Please consult Google if you don’t believe me about this! You can check out Favorite Healthy Sweet Potato Recipes if you’re a sweet potato fan!

Which Air Fryer Did I Use:

I first got this NuWave Air Fryer (affiliate link) and used it with good results to make Spicy Sweet Potato Fries; after I became an Air Fryer convert I splurged on this Cuisinart Convection Air Fryer Toaster Oven (affiliate link).

How to Make Air Fryer Spicy Sweet Potato Fries:

(Scroll down for complete recipe with nutritional information.)

  1. Peel sweet potatoes, cut into thick slices, and then slice into fries. (There are photos of this in the recipe for Spicy Baked Sweet Potato Fries if you want more about how to cut them up.)
  2. Mix together the ground coriander, ground fennel, ground oregano, Aleppo pepper (or cayenne), and salt to make the spice blend.
  3. Toss the fries with 2 T olive oil and about 1 T of the spice mixture. (You can probably get by with a bit less oil, but I wanted to be sure the spice mixture would stick.)
  4. Pre-heat the Air Fryer to 350F (if needed) then add the fries and set cooking time for 27 minutes.
  5. Cook the sweet potatoes for 15 minutes without opening the Air Fryer.
  6. After 15 minutes, remove the basket from the air-fryer and use a large turner to quickly turn the fries (so the ones on the bottom are now on the top).
  7. Push the basket back into the Air Fryer and cook for 10-12 minutes more, or until fries are cooked through and golden brown.
  8. My Air Fryer will resume cooking for the programmed amount of time when you push the basket back in. For some models, you may need to set the time and/or push start again.
  9. Serve hot and enjoy!

Air Fryer Spicy Sweet Potato Fries are so delicious and these perfectly-seasoned sweet potato fries are so easy to make in the air fryer!


  • 2 large sweet potatoes (see notes)
  • 2 T olive oil (see notes)
  • 2 T sweet potato fry seasoning mix
  • Spicy Dipping Sauce with Sriracha, optional but good! (link below)

Seasoning Mix Ingredients:

  • 2 T ground coriander
  • 1 T ground fennel
  • 1 T dried oregano
  • 1 T Aleppo Pepper
  • 2 T kosher salt


  1. Cut off both ends of the sweet potatoes and peel with a sharp vegetable peeler. Then cut each sweet potato in half lengthwise and again crosswise so you have four pieces.
  2. Slice each piece into 2 or 3 thick slices, then cut each slice into fries. (I made them about 1/2 - 5/8 inches thick, or about 15-18 cm.)
  3. In mortar and pestle or spice grinder, grind together coriander, fennel, oregano, and Aleppo pepper. Mix in salt. (This makes enough for several batches of sweet potatoes, so you'll need a small jar to store the extra.)
  4. Preheat the Air Fryer to 350F while you put the cut fried in a bowl and toss with olive oil, and then with the seasoning mix.
  5. When the preheating is done, add fries to the basket of the Air Fryer, set time for 27 minutes, and push start. Cook the fries 15 minutes.
  6. After 15 minutes pull out the basket and use a large turner to quickly turn the fries (so the ones that were on the bottom are now on the top).
  7. Shut the Air Fryer and let it cook 10-12 minutes longer, or until fries are cooked though and goldden brown. (My Air Fryer will resume cooking for the programmed amount of time when you push the basket back in. For some models, you may need to set the time and/or push start again.)
  8. Serve hot, with Spicy Dipping Sauce with Sriracha if desired.


We used about 1 1/2 lbs. total weight of sweet potatoes after peeling. You can probably get away with less olive oil, but I wanted to be sure the seasoning mixture would stick well to the fries. We used ground corianderground fenneldried oregano, Aleppo Pepper, and kosher salt for the seasoning mix.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
These Air Fryer Spicy Sweet Potato Fries are South Beach Diet approved for phase 2 or 3, and they’re also vegan, dairy-free, and gluten-free. Frying will raise the glycemic index of sweet potatoes compared to other cooking methods though, so you might want to reserve them for an occasional treat. Sweet potatoes are probably too high in carbs for most low-carb eating plans.

  1. Bit disappointed to read all the way down to find you do use oil as your page is linked to the above page (oil-free). 

    • I have no control over whether another site links TO me; you need to complain to that site if you’re bothered by it. And did you notice I said “You can get away with less oil but I wanted to be sure the seasoning stuck to the fries.” So using oil or not is your choice.

  2. I looked up OIL FREE recipes for air fryer and this did not meet that criteria

    • Not sure what you mean by “looked up” but if you used the search bar on my site that will send you to the recipe that has the best match, so it found “air fryer”. Most of my air fryer recipes have a little oil for best flavor, so I will save you some time checking on that. You can probably omit some or all of the oil, but of course I haven’t tested them that way.

  3. You might want to check on the low-glycemic claim. There have been studies that show that air frying will turn the sweet potato into candy and raise the glycemic number.

    • I have not heard about that. I am not finding a conclusive study; I’d love to have the link for the study if you have one. But I have have changed my information based on what I did find online.

  4. What watts setting do you use?

    • My air fryer doesn’t have a way to change the watt setting. But on the back it says 1300 watts. Hope that helps!

  5. I made these but the chips turned out kinda soggy. Any tips on making it crispier? Thanks!

    • I’m wondering if this is your first time making sweet potato fries, because they never get as crispy fries from regular potatoes. It’s possible that different Air Fryers cook slightly differently, so you could try using a higher temperature or longer cooking time, but other than that the only tips I know are in the recipe. Ours were definitely crisper than sweet potato fries made in the oven.

  6. I’ve debated about getting an air fryer. The fries look delicious!

    • Barbara, it’s definitely great for these and other things that would normally be fried. Also quick for some things. Not sure how much I will end up using it, but fun!

  7. I bought an airfryer on a whim about 6 months ago when it was offered on sale. I am obsessed with it. The name is almost a misnomer. You can cook so many things with it not just “fry”. It was great over the summer as it doesn’t heat up the kitchen. You can toast bread, maked toasted sandwiches, toast nuts, “grill” fish and meats, bake small cakes in short amounts of time.

    It is really a concentrated convection oven. Now that we are in sweet potato season, I will be making some of these “fries”.

    • Fun hearing how you have used it! I know I’ve barely scratched the surface!

      • Forgot to mention Tofu. cut in up in cubes, season. then “bake”. They come out crispy on outside still somewhat moist on inside . I’ve tossed the baked cubes in a stir fry as they will now hold their shape. The cubes also make a great snack, sort of “popped” tofu.

      • Air Fryer tofu sounds like something I must try!

  8. I may have to get one of these fryers! You tossed the potatoes in oil. Is that all the oil that is used? Is there oil in the actual fryer?

  9. Oh how I love sweet potatoes and my kids are going to love these sweet potato fries. Thanks for the shout out to my Sweet Potato Hash!

  10. Sweet potato fries is even better than the regular one! 😀

  11. I don’t think I’ve ever even seen an air fryer! It’s so much fun to get to know a new kitchen gizmo. And sweet potato fries…. well, they are the best!
