Baked Sweet Potato Fries

crispy baked sweet potato fries recipe

Attention: these sweet potato fries will change your life. I’m serious! Salty-sweet, crunchy, and spicy if you wish, baked sweet potato fries are my favorite new snack.

These fries beat their plain jane, fried Russet cousins in terms of simplicity and ease; they require fewer cooking steps because they’re baked rather than fried. In fact, I learned how to bake these fries by learning from adorable Amy Cao’s aptly-named “Stupidly Simple Snacks” video series. You can enjoy sweet potato fries in 45 minutes, start to finish, with minimal effort.

Sweet potato fries pack a nutritional punch, too. One baked sweet potato contains over twice the amount of vitamin A you need for the day (source: Whole Foods). Trust me, it’s easy to eat more than one sweet potato worth of these fries!

According to The New York Times, sweet potatoes are complex carbohydrates that contain protein, which pretty much means that you can eat these fries with abandon. Trust me, I have tried and I can confirm that this is true. You can eat an entire sweet potato (or two) of fries and you will not feel hungry or tired an hour later.

I’m all for guilt-free indulgences, aren’t you?

Baked Sweet Potato Fries

Ingredients
  • Sweet potatoes. I’d plan on at least one per person.
  • Corn starch. A big sprinkle’s worth. (optional)
  • Olive oil. A couple of tablespoons or so.
  • Salt, pepper and spices. Amy suggested cumin, but I much prefer cayenne pepper, paprika or curry powder. Garlic is great as well. It’s up to you!

Instructions
  1. Preheat the oven to 450 degrees F. Peel the sweet potatoes and cut them into fry-shaped pieces (see photos). Try to cut them into similarly sized pieces so the fries will bake evenly.
  2. Toss the uncooked fries into a mixing bowl or a plastic bag, or just onto your baking sheet. Sprinkle with cornstarch (if using) and pour in a few tablespoons of olive oil, enough to lightly coat the fries. Season with salt, pepper, and spices. I’d try to use half a teaspoon per potato or so. Mix/shake to distribute evenly (corn starch should be evenly mixed in so there are no powdery spots).
  3. Pour the fries onto a non-stick baking sheet or a baking sheet covered with parchment paper (aluminum foil produces mixed results). Arrange the fries in a single layer. It is very important to keep them in a single layer, otherwise they will never crisp up. Give each fry a bit of room on the baking sheet.
  4. Bake for 15 minutes, then flip the fries so they can cook on all sides. I find the easiest way to flip them is with a metal spatula. Section by section, scoop up about ten fries and flip them with a quick turn of the wrist.
  5. Bake for 10 to 15 more minutes, until the fries are crispy. You’ll know they’re done when the surface of the fries change from shiny orange to a more matte, puffed up texture. It’s essential to bake them long enough, otherwise they won’t be crispy. Don’t worry if the edges are a little bit brown, they will taste more caramelized than burnt.

Notes
  • Commenter Jeni of Bear + Goose suggested adding a bit of corn starch to help make the fries more crispy. It totally works. I personally skip the corn starch most of the time because my fries get as crispy as shown in the photos without it, but I’ve heard from several people whose fries never turn out crispy enough… so try it!
  • This sharp little Y-shaped vegetable peeler makes peeling sweet potatoes a breeze and costs around six dollars.

Voila! Sweet potato fries. Don’t tell me I didn’t warn you… they are addictive! Please try them and let me know what you think!

    Holy moly!! These look DEEE-LICOUS! Sweet potatoes are my absolute favorite and I’ve attempted sweet potato fries several times, but they’ve never turned out looking these yummy. I’ll have to give them another shot with your recipe!

    Hi there! I tried these tonight and you’re right my life has been changed forever. I just have to work a bot more on the crispiness and then I might never eat anything else ever again.

    • Posted December 31, 2010 at 4:22 PM | Permalink

      So glad to hear it, Lesley! Try sprinkling the fries with corn starch before mixing it all up with olive oil. It really does help!

    i love mine with sugar on top and dipped in ketchup

  7. Posted December 15, 2010 at 8:28 AM | Permalink

    Yum! They look perfect. I love them with a nice and simple garlic aioli, too – my fave!

    • Posted December 31, 2010 at 4:24 PM | Permalink

      Hey Sarah! I have yet to try these fries with garlic aioli (I’m a ketchup fiend), but they are definitely amazing when baked with minced garlic!

    Oh I am making these TOMORROW.
    Thanks for sharing this wonderfully written and photographed recipe.

    Love your site BTW.

  9. Posted December 16, 2010 at 8:18 AM | Permalink

    Whenever I bake mine they do not turn out nearly as good as your look. I have made a mental note of what you did, and will definitely be making them your way. Thanks for sharing. I am your newest follower.

    no need to tell me twice! i LOVE sweet potato fries! best part is that you don’t ever have to actually fry them! i discovered that a little corn (or potato) starch will help them crisp up just enough! so delish!

    I found this on foodgawker and it has become my go-to fry recipe! For me though, I find that baking them for only 15 minutes on one side is enough :)

    Thanks for the tip about cornstarch to get them crispy (I’ve been searching for the secret to getting them crispy for awhile). I also have a tip to share: use a metal baking rack over top of a pan (in case any should fall through), and you shouldn’t need to flip the fries :)

    • crystal
      Posted December 17, 2012 at 8:20 PM | Permalink

      luv the idea of using a metal baking rack w/pan underneath. especially because parchment paper only stands temps up 420 degrees..mine started browning w/in 5mins, turned the heat down & are baking 20mins befor first flip..dont have a baking sheet as of now. Question: recipe says sprinkle in corn starch at the end after oil & seasoning..then in a response to a person comment , you (Kate) say to sprinkle on befor olive oil & seasoning… which is it?.. or does it make a difference?.. thankyou!

      • Posted December 19, 2012 at 3:14 PM | Permalink

        Hi Crystal, how did the sweet potato fries turn out on the baking rack? I haven’t tried that trick yet. I don’t think it matters when you sprinkle on the corn starch, just be sure it’s mixed into the olive oil so there aren’t powdery white patches.

  14. Posted September 17, 2011 at 10:35 AM | Permalink

    I do these with aleppo pepper and it adds a smokey, spicy character to the potatoes. One of my favorite snacks!

  15. Posted October 26, 2011 at 4:28 PM | Permalink

    I usually end up burning the fries trying to get them crispy. I can’t wait to try your method with the corn starch! Thanks for the great tip.

  16. Posted April 18, 2012 at 10:09 PM | Permalink

    My sweet potato fries were always a bit mushy instead of crisp like a french fry, until I prepped them the day before I made them (cut into fry size) and salted them. I left them overnight in the fridge and the next day when I baked them they were much crisper than when I had made them in the past.
    Also nice for busy people. Prep the potatoes when you have time, bake them the next day when you are hungry.

    • Posted April 21, 2012 at 10:47 AM | Permalink

      That is a really interesting technique, Alyssa! I bet the salt helps draw out some of the moisture. I’ve come across a technique for crispy oven-baked fries made with regular potatoes that required soaking the cut fries in salt water (I think it was from America’s Test Kitchen). I’m intrigued.

        Posted June 2, 2012 at 6:30 PM | Permalink

        Another method that I have found works well is that I bake for a half hour at a low temperature around 275-300 degrees. This is mostly to remove some of the moisture. Then I crank up the temperature to 450 degrees and cook 10 minutes and then flip and cook for another 10 minutes and then they are nice and crispy. This works well for both sweet potatoes and regular potatoes. Sweet potatoes tend to have more moisture in them than regular potatoes and so it may take a little longer.

          I put a cookie cooling rack on my cookie sheet and placed the fries on the cooling rack. I didn’t have to turn the fries and my cooking time at 450 was reduced to 20 minutes, and still nice and crispy.

          • Posted October 31, 2012 at 12:34 PM | Permalink

            Great idea, Stan! I’ll give that a try.

    Made these a few nights ago as a side with these Green Chili Chicken Burgers http://www.howsweeteats.com/2012/04/green-chili-chicken-burgers/ and I took your advice and used the 1/2 tsp of cornstarch and they were crispy and delish! Super easy and will be making these many more times!

  18. Posted May 11, 2012 at 11:02 PM | Permalink

    I don’t know what I did wrong, but my fries were completely stuck to the pan. I used foil and plenty of olive oil and after 15 min, they were so stuck that I couldn’t flip them. What could I try differently next time?

    • Posted May 29, 2012 at 3:29 PM | Permalink

      Uh oh, I’m sorry to hear that! My fries stuck to the foil one time when I tried using another method that called for egg whites. I blamed the egg whites, but maybe it was the foil! Contrary to the photos above, I usually bake my fries directly on my non-stick baking sheet or on parchment paper. I have never had my fries stick to parchment paper. I just edited my recipe to reflect these tips, hope your next batch turns out great!

      • Bekah
        Posted May 29, 2012 at 3:46 PM | Permalink

        Thanks! Yeah, I’m guessing it was the foil. I usually bake on parchment, but I saw foil in the picture and went for it. I guess I learned the hard way. :) I’ll try the same method but with parchment next time!

        • Posted May 29, 2012 at 9:12 PM | Permalink

          Yeah, I’m sorry about that! I took down that photo since it’s misleading.

    Hi Kate – tried these a few times and had varying results, but love sweet potatoes and will keep trying to perfect this.

    First two times I put fries directly on an aluminum heavy duty baking sheet, but did not have significant issues with sticking or cleanup. This time I used same pans and used the parchment paper, but also varied by using the convection bake feature of our oven which I hoped would crisp them even more.

    This time they came out very soggy and not sure what went wrong.

    • Posted June 11, 2012 at 11:23 PM | Permalink

      Hmm. I do not have any experience with convection ovens so I can’t say anything about that. I know I have had success using parchment paper so I don’t think that is the cause. I would guess that either the fries were overcrowded in the pan or that they weren’t baked long enough, but maybe it was due to the convection oven feature? I wish I knew!

        Yams have significantly less sugar according to a vendor I talked to at the Farmers’ Market yesterday. I think they won’t be as tasty.

    Beautiful Blog!
    I find that whenever I bake sweet potato fries, they don’t have enough of a crunch to them. I’ll definitely try the cornstarch idea! Thanks :)

  29. Tami
    Posted September 13, 2012 at 9:49 PM | Permalink

    To add a bit of extra crunch, what about scoring the chips lightly with a fork to rough up the edges before baking? It works a treat with my baked potatoes every time I do a roast dinner, might work for this too!

    • Posted September 19, 2012 at 7:19 AM | Permalink

      Great idea, Tami! I’ll try that next time.

    If you have not tried Old Bay on sweet potato fries, you should. Old Bay is a Maryland seasoning used on blue crabs. Very good as a seasoning for fries.

    GREAT Recipe for flavor. I am however, often surprised that we use organics and create healthy recipes..and put them on aluminum foil, so the foil is heated and contributes to our possibility of Alzheimer’s.

    Posted October 13, 2012 at 12:04 AM | Permalink

    Great recipe and flavor! I just made these for my roommates and they were amazing. The only thing that came out a bit different is that mine were not as crispy as I wanted them. I had to transfer them to my toaster oven for a bit. Any suggestions for next time?

    • Posted October 15, 2012 at 2:04 PM | Permalink

      Sigal, my only suggestions would be to make sure there’s ample space around each fry (don’t overcrowd) and be sure to bake the fries long enough. You could always move them up to the top rack of the oven for a few minutes if they are not crispy enough. Did you try the corn starch trick?

  33. Posted October 13, 2012 at 5:50 PM | Permalink

    I googled sweet potato fries and then looked for a private blog, i.e. not Paula Deen or Epicurious. Yours was the first I clicked and voila – these look great and mine are going in the oven as soon as I finish writing this. I added the cornstarch as you recommend – I’ll try to post and let you know how they turn out. Wish me luck!
