Three ingredient home-baked fries with a secret ingredient! Slide a batch of crispy baked sweet potato fries alongside your next sandwich or burger… they’re easy to make and absolutely addictive with a spicy Sriracha ketchup!
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
- 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.
These fries look wonderfully addictive, I need to try your cornstarch trick!

Your fries look so crispy and crunchy. And I love the combo of spices you used — yum! Cayenne has become one of my go-to spices this season. I just can’t get enough!
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… :)

Ugh, sweet potato fries are my kryptonite–I just can’t resist. Will definitely be making them this weekend!

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:
These are one of my all-time-favorite snacks! Need to make a batch asap!
That’s me most nights, too. I just don’t have the energy to cook after work. I would be happy with a big ol’ plate of these here fries. Yum!
They look gorgeous, love sweet potato fries anytime. Great idea to bake em’ with cornstarch.
I have to start making more of burgers, miss it.
Beautiful looking fries!! So much healthier than deep frying!
Best. Snack. Ever.
I could eat these Sweet potatoes fries by the handful!
I’ve used cornstarch to baked perfectly crisp fries. It truly works!
These look fantastic Georgia and I can’t believe it’s oven baked?! Wow.. it’s “fried” perfectly! So crispy and delicious. And healthy too! I love it! :)
I made some pretty soggy, lackluster sweet potato fries last night so I am definitely going to try your version! They look so perfectly crispy!
Oh I so wish I had these right now to eat for lunch!
I loveeeeeeee the photos. Can you believe I’ve never baked with Sweet Potatoes.. always use the idaho ones and make fries. Love this idea… I always get sweet pototo fries at Latin restaurants. :-)
I reach for the sweet potato fries over regular every single time. Love these.
I gasped out loud when I read your tip for getting them to crisp up–oh yes, I am that much of a nerd for sweet potato fries. :) I am totally going to try this!
Ah so cornstarch is the secret! I like sweet potato fries drizzled with maple syrup – and the crispier, the better!
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!
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!!!
Thanks so much for the cornstarch tip! I now know how to get really crisp fries when I make/bake them at home. Great tip.
Forget regular fries, it’s all about sweet potato fries for me. These look absolutely perfect, Georgia!
Soaking the sweet potato fries for an hour or so before baking helps keep them crispy too!
Gorgeous fries! I love that you gave the sweet potato such a sexy look with these fries. :)
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?
I’ve never tried it, but it could work!
Oh yum! These are absolutely delicious. I had tried making sweet potato fries before, but had a hard time getting them really crispy. These are PERFECT!!
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!
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!
Just toss the fries in a mixture of all three (cornstarch, oil and spices). You don’t need to combine them all first.
Make your own rosemary salt and use it on the sweet potato fries. It is a marriage made in heaven.( I just grind up some rosemary and combine it with kosher salt.)
