I was happy I managed to get some good photos this week to update this favorite recipe for Spicy Sweet Potato Fries. The first time I made this recipe, I took one bite and knew immediately I’d be making these sweet baked potato fries over and over. My favorite sweet potatoes fries are not only meatless, but this recipe is deliciously vegan. Who knows, this just might become your favorite way to cook sweet potatoes? And if you have an Air Fryer, you might want to try Air Fryer Spicy Sweet Potato Fries, which are just slightly more crisp than the baked ones!

Do I Need to Cut Up Whole Sweet Potatoes?

You can certainly make this recipe with those pre-cut sweet potato fries that show up in the stores this time of year, but I prefer to cut my own so I can make them a little thicker.  Having a little more thickness lets me cook them slightly longer for maximum crispness, although sweet potatoes don’t ever get as crisp as regular fries.

Sweet Potato Info:

Orange-fleshed sweet potatoes are often called “Yams” or “Sweet Yams” in the United States. but they’re really sweet potatoes. Please trust me on this. (There’s also a tan-skinned variety of sweet potato with white flesh; I used those in Roasted White Sweet Potatoes with Red Onions.) And if you’re a fan of savory recipes with sweet potatoes, you can check out Favorite Healthy Sweet Potato Recipes to see my personal faves.

How to Make Spicy Baked Sweet Potato Fries:

(Scroll down for complete recipe including nutritional information.)

  1. Cut off both ends of the sweet potato and use a sharp vegetable peeler to peel off the skin. (Thanks to my brother Dave and sister-in-law Amy who gave me this Cutco vegetable peeler that I love!)
  2. Then cut the sweet potato in half lengthwise and again in half crosswise, so you have four pieces.
  3. Slice each piece longways into 2 or 3 slices.
  4. Then cut each slice into 4 or possibly five fries.
  5. I like to make thick fries, about 1/2 to 5/8 inch thick (15-18 cm.) I don’t mind if the pieces are a little irregular, it adds to the charm!
  6. Put the fries into a large bowl and toss with enough olive oil so all the fries are very lightly coated with oil (1-2 tablespoons of oil for 2 sweet potatoes, depending on how big the sweet potatoes are.)
  7. Then sprinkle with 2-3 teaspoons of spicy sweet potato fry seasoning (see recipe for how to make that.)
  8. Use the largest baking sheet you have and spray with olive oil or non-stick spray. Arrange sweet potatoes so the flat side is down and they’re not touching each other. (Use 2 pans if your pan isn’t big enough.)
  9. I used to bake these at 425F, but I’ve come to like them better cooked at 450F/230C, and that’s the temperature I used this time.
  10. Cook 15 minutes, then use your fingers or a fork to turn them over and put back in the oven.
  11. Cook 15 minutes more and turn them again.
  12. Put back into the oven. Cook another 5-10 minutes, depending on how well-done you like them.  (I cooked mine about 7 minutes more.)
  13. Spicy Dipping Sauce with Sriracha is my favorite for dipping sweet potato fries!

Spicy Baked Sweet Potato Fries

Spicy Baked Sweet Potato Fries

Yield 4 servings
Prep Time 15 minutes
Cook Time 40 minutes
Total Time 55 minutes

These Spicy Baked Sweet Potato Fries are a meatless side dish that you'll make over and over!


  • 2 orange-fleshed sweet potatoes
  • 2 T olive oil (see notes)

Spice Mix Ingredients:

  • 2 T ground coriander
  • 1 T ground fennel
  • 1 T dried oregano (use any Mediterranean oregano like Greek Oregano or Turkish oregano, but not Mexican oregano for this.)
  • 1 T Aleppo Pepper (or use a smaller amount of cayenne pepper)
  • 2 T kosher salt


  1. Preheat oven to 450F/230C.
  2. 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.)
  3. 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.
  4. 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.)
  5. In plastic bowl, toss together cut sweet potatoes, olive oil, and spice mixture. You will need about 2 tablespoons olive oil and 2-3 teaspoons of the spice mixture for two sweet potatoes, depending on how big the sweet potatoes are and how spicy you like it.
  6. Spray flat roasting pan with non-stick spray. (Use the largest baking sheet you have.)
  7. Spread out sweet potatoes in single layer, with the flat side down and not touching each other.  (Use two baking sheets if yours is too small to do this.)
  8. Roast sweet potatoes 15 minutes, then use your fingers or a fork to turn each sweet potato.
  9. Roast 15 minutes more and turn again. Roast another 5-10 minutes, depending on how done you like them.
  10. Serve hot, with Spicy Dipping Sauce with Sriracha, if desired.


Use more or less oil to taste, but you want enough oil to make the spice mix stick to the sweet potatoes. Recipe adapted from Epicurious.com.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Sweet potatoes are probably too high in carbs for most low-carb eating plans, but they’re considered a “good” carb for the South Beach Diet (unlike potatoes, which are very high on the glycemic index.) This would be a great side dish for phase two or three of South Beach.

  1. This recipe looks great! Thanks for sharing. Can’t wait for dinner now!

  2. This recipe is quite amazing! I really love the combination of spices. I ground everything up in my blender, and it was great. I feel that if you wanted to, you could cut back on the salt.

  3. Anonymous, your spice combination sounds like it would taste great! Unfortunately for South Beach Dieters, the brown sugar would not be an approved addition to the recipe. Just mentioning that for anyone who didn’t know.

  4. I was just poking around the internet when i came across this post but i wanted to put my two cents in 🙂

    My spice combination included:

    Cayenne pepper
    Black pepper
    Garlic Powder
    Brown sugar

    …i think that little bit of brown sugar really helps balance the spices for a nice deep balanced flavor with just the right hint of kick.

    Admittedly this combo is amalgated from a few different recipes i came across. Hope it helps!

  5. I just wanted to let you know that we linked to your recipe on this page:
    Thanks very much! Great stuff!

  6. Margaret, very good point. I don’t know why I peeled them, other than that’s what the recipe said to do. Definitely I think I’ll try them not peeled, and I bet the skin part will be delicious, all crispy from roasting. Let me know if you try it that way too.

  7. Yes, these are a great frenchfry alternative. I am wondering why you peel the potatoes, especially if you use organic sweet potatoes, then you get the peel benefits too.

  8. I’m so making these! As it is, I often make sweet potato “wedges” with BBQs – I don’t even peel them, just a good scrub, cut into wedges, tossed in olive oil and sprinkled with rosemary before roasting. When they come out they get a quick sprinkle of salt & that’s it. People can’t believe what they’re eating when I tell them, especially fussy kids! I’m dying to try your spice mix…

  9. Now I’m salivating! I love sweet fries to begin with but haven’t tried them with the herbs. I just use a little salt and pepper and they wow me when cooked that way so this will probably put me in shock! Thanks for flingin’ a cravin’ on me. Off to check my spices to see what I need and don’t have!

  10. droooool! Those look better than sex! Okay, better than bad sex. They’re on my must cook list. Thanks for the recipe.

  11. Rob, how fun! I do hope you like them. I’ll have to remember that place if I ever get to London (hopefully someday!)

    Karina, I was completely surprised at how wowed I was by the coriander/fennel flavor combo here.

    Lydia, I’m also a convert now! Better for my diet too.

    Mansi, thanks for the invite. Unfortunately I hardly ever have time for many events since I teach school, write for Blogher.org, and spend so much time on this blog!

    Kelly, yes. Very South Beach friendly. Healthy for any diet!

    Tanna, love that Aleppo pepper.

    EMWK, happy to hear from another SP fries lover.

    Ex-Pat Chef, your version sounds great too!

    Amy, yes. When I went to the store I bought a big bag of sweet potatoes (called sweet yams in my store.)

    Nupur, glad you liked the idea! Cumin sounds like it would taste great on this too. Do post your version!

  12. Thank you for this recipe, Kalyn! I made these fries last night (with a simple salt-cayenne pepper-cumin rub) and they are *delicious*.

  13. Wow these fries sound amazing! Another wonderful fall dish. Yum!

  14. I will HAVE to try that spice mix! I do mine with coarse sea salt, pepper, and cumin, then dust with parmesan. We love the baked fries like this.

  15. I made so much sweet potatoe fries in summer and I’m into baking sweet potatoe pies now. But seeing your recipe made me want those fries again. 🙂

  16. Let’s see . . . Monday will be the first day I can get these on the table. My Aleppo pepper is in Dallas.

  17. Delicious fries! And because it’s sweet potatoes, they’re good for you and I can eat more, right? 🙂

  18. we have sweet potato fries when we are fasting!:) its yummy!!and fennel sure sounds interesting…

    btw, I’m hosting AFAM-Peach event on my blog this October..I’d be glad if you could find some time to send in an entry!

  19. I’m a recent convert to sweet potato fries, and I love all things spicy. Will definitely be bookmarking this recipe!

  20. I love sweet potato fries! I’ve never tried them with ground coriander. I’ll have to pick some up.

    Thanks for another fabulous recipe- as always.
