This fall for me has been a little more fast-paced than in years past. I don’t feel as overwhelmed by everything there is to do as much as the time there is to do it! When days melt into weeks that whiz past into months, it’s hard to feel like you’re doing everything well instead of just barely balancing plates. But, I’m making it work! Hot cups of apple cider and turning off technology before dinner help relax me.

On nights when you just can’t be bothered to make a fuss (which lately for me, are most nights), what do you cook? We throw burgers on the grill and a batch of spiced, crunchy sweet potato fries in the oven. Simple, easy and absolutely delicious.

In the past, I always struggled with getting these little buggers to crisp up, but cornstarch has taught me a lot! Sprinkling it into your spices that you coat the fries with helps absorb excess moisture from the potatoes and perks up your fries to a nice, crispy golden brown.

Say g’bye to those lame, limp fries of past failures (we’ve all had them) and hello to sweet potato perfection!

Want the secret to the best seasoning for your fries? Use a combination of spicy, salty and “sweet.” I go for chili powder, garlic, cinnamon, cumin and a dash of cayenne ‘cuz we like our fries with an extra kick! With a combination of any of my below spice suggestions, you basically can’t go wrong. Mix it up with dried herbs, too! Rosemary and thyme send sweet potatoes into major comfort food territory!

You’ll love these crispy, crunchy sweet potato fries as a simple snack or an awesome side to burgers and sandwiches. Grab the three ingredients needed, a handful of your favorite spices and get bakin’ these fabulous un-fried treats! I love to serve them with Ranch dressing and a spicy Sriracha ketchup. Yum!

Crispy Baked Sweet Potato Fries

Yield: Makes 3 large servings


3 sweet potatoes, peeled

1/4 cup olive oil

3 Tablespoons cornstarch

Generous amounts of salt, pepper and desired spices (see below for ideas)


Spice options (or use whatever you like!):


Garlic powder

Chili powder

Cayenne pepper





Preheat oven to 400 degrees F. Prepare two large baking sheets with parchment paper.

Slice sweet potatoes into thin, uniform fries. Toss fries in olive oil, cornstarch, and desired spices. Lay fries out in one layer on prepared baking sheets, making sure not to crowd the fries, otherwise they will steam and not crisp up.

Bake for 30 minutes, watching carefully to avoid burning. Serve warm with ketchup, Ranch dressing, or your desired dipping sauce.

    I’m so excited to see an incredibly crisp sweet potato fry! Achieving that texture is so challenging. And the spice blend you’re using is right up my alley! Although I’d probably toss in just a touch of Old Bay. I put Old Bay on just about everything… :)

    Mine never crisp up, so I’m definitely trying the cornstach tip! Yay, I’m so making these soon, they look spectacular and sound like a perfect dish to carb load before my half-marathon. I’m sure they taste amazing as well, because I made your recipe for turkey meatballs yesterday and I loved it so much. Thanks for both recipes! c:

    Ah so cornstarch is the secret! I like sweet potato fries drizzled with maple syrup – and the crispier, the better!

    Rachel @thedessertchronicles — October 29, 2013 @ 9:06 pm

    So excited to learn this little secret! I love making sweet potato fries at home, but I can never get them to crisp up in the oven. I will have to add cornstarch and try your spice mix next time!

    Nami | Just One Cookbook — October 30, 2013 @ 3:18 pm

    I’m definitely going to try this ASAP. I love sweet potatoes, and yours are truly perfection. I can see very well from the beautiful pictures you took. I’m super tempted right now and going to get sweet potatoes on the way to pick up my kids! Excited!!!

    Forget regular fries, it’s all about sweet potato fries for me. These look absolutely perfect, Georgia!

    carly — October 31, 2013 @ 12:03 pm

    Soaking the sweet potato fries for an hour or so before baking helps keep them crispy too!

    Ramona — November 2, 2013 @ 6:38 am

    Gorgeous fries! I love that you gave the sweet potato such a sexy look with these fries. :)

    Stacy | Wicked Good Kitchen — November 4, 2013 @ 4:37 pm

    We love sweet potatoes any which way in our house…especially crispy in the shape of fries! Read about cornstarch being such a workhorse to get the crispy exterior for oven fries. Just haven’t tried it yet (with tapioca starch), but now I simply must! Such inviting photography here, Georgia. Thanks for sharing!

    Wow, looks so yummy! Can I subtitute the cornstarch with arrowroot?

    • Georgia — November 19th, 2013 @ 10:39 am

      I’ve never tried it, but it could work!

    Chelsea @ Gal on a Mission — January 29, 2014 @ 12:42 pm

    Oh yum! These looks absolutely delicious. I have tried making sweet potato fries before, but had a hard time getting them really crispy.

    Brenda Mills — April 7, 2014 @ 7:46 pm

    Had not thought of using corn starch to crisp up oven fries, but I have used it for years in making crispier crust on coconut shrimp,fried green beans,etc. just mix in with your flour or breading of choice very well, works well on chicken strips also.Now I’ll try your sweet potato fries!

    BP — April 8, 2014 @ 2:59 pm


    I am wondering if you could make a slight clarification.

    Do you add the CS and spice to the oil or do you oil first and then put in the CS and spice mix?

    Thanks! Can’t wait to try this recipe!

    • Georgia — April 8th, 2014 @ 7:22 pm

      Just toss the fries in a mixture of all three (cornstarch, oil and spices). You don’t need to combine them all first.

    Madelyn — June 7, 2014 @ 7:29 pm

    When I tried it my fries totally stuck to the parchment paper. Was I supposed to grease the parchment?

    • Georgia — June 7th, 2014 @ 9:11 pm

      Parchment paper should provide a nonstick surface for your fries to bake on top of – no need for cooking spray. I’m not sure why they would have stuck!
