Are Baked Sweet Potato Fries Healthy?
I love this recipe because itβs a healthy treat that kids actually love. Sweet potatoes have slightly more carbs and calories than regular white potatoes, but contain more antioxidants, fiber, and vitamins A, C, and B6. Additionally, baking the fries uses significantly less oil than deep frying, which lessens the fat and calorie content.
Only 4 Easy Ingredients
This is all you need to make this recipe:
- Sweet potatoes
- Cornstarch
- Olive oil
- Salt and fresh cracked pepper
It doesnβt take much to spruce up these fries. The light seasonings compliment the natural sweetness from the potatoes, but if you like a little extra flavor or heat, add a few pinches of garlic powder, paprika, parmesan cheese, or a touch of cayenne to the finished fries.
The Magic of Cornstarch
You may be wondering: why are we adding cornstarch before baking? It just so happens to be the secret to super crispy baked sweet potato fries. Tossing the cut fries in olive oil and cornstarch acts as a coating that will adhere to the outside of the potato, crisping it up as it bakes.
Preparing The Sweet Potatoes for Homemade Fries
These fries wonβt be soggy and will cook evenly as long as we follow each step precisely. Hereβs how I achieve super crispy sweet potato fries:
- Peel The Potatoes: The potatoes will be able to soak in the oil, cornstarch, and seasonings easily once their skin is removed.
- Cut The Fries Evenly: Slice the fries into even sizes and widths to allow for even cooking. If the fries are all different sizes, theyβre more likely to cook inconsistently (meaning burnt or undercooked fries).
- Give Them A Bath: This step is optional, but once the fries are cut, you can toss them a bowl with cold water. Letting them soak for up to 12 hours will remove any access starch and help them become more crispy in the oven. Once theyβre finished soaking, thoroughly rinse the fries and dry them well.
- Lay Them Flat: Like I said, we have to be precise! Lay the fries flat and spaced apart on the baking sheet before roasting. If theyβre piled on top of each other, the fries on the bottom wonβt stand a chance of cooking properly.
How to Make Sweet Potato Fries In The Oven
You canβt get crispy fries without high heat! 425ΒΊF is the optimum temperature to bake sweet potato fries. Any lower and theyβll turn out soggy.
- Preheat the oven to 425Β°F. Line a large cookie sheet with parchment paper or non-stick aluminum foil.
- Place the cut fries in a large ziploc bag or bowl and drizzle 2 tablespoons of olive oil overtop. Shake the bag or mix the fries until theyβre evenly coated. Next, sprinkle in the cornstarch and mix again until everything is covered.
- Add 1 final tablespoon of olive oil and mix until the white from the cornstarch disappears. Sprinkle the salt and pepper overtop and toss the fries one last time!
- Lay out the sweet potato fries evenly, in a single layer, on the baking sheet. Roast them for 25 to 30 minutes, flipping halfway through.
- The fries are best served fresh and hot out of the oven. Finish with an extra sprinkle of salt and pepper or any of your favorite seasonings and enjoy!
How to Make Sweet Potato Fries In An Air Fryer
Spend a little less energy by making these fries in an Air Fryer instead of the oven. To do this, prepare the potatoes as you would when baking the fries. Use only 1 Β½ tablespoons of olive oil when tossing the fries with cornstarch and seasonings. Heat the Air Fryer to 375ΒΊF, and lay the fries in an even layer on the tray (fry in batches if you need to). Cook each batch for 15-17 minutes, flipping the fries halfway.
Can I Make These Ahead Of Time?
Sweet potato fries are a perfect snack to prepare well ahead of time. I like to cut up my potatoes and store them in a ziploc bag in the fridge until I need them. This way, all I have to do is season, bake, and serve the fries an out-of-the-box after school snack or a fun late night treat in no time!
How To Serve Baked Sweet Potato Fries
These fries are excellent as a healthy alternative to regular junk food or as a side dish for both lunch and dinner. Whip up a few of my Crock Pot Pulled Pork Sandwiches with these fries on the side, or create a hearty and satisfying weeknight meal by enjoying them with my favorite juicy baked chicken.
Donβt forget the dipping sauce! I love these super simple fries dipped in regular ketchup and mayonnaise, but theyβre also tasty with chipotle mayo, barbeque sauce, ranch dressing or even marshmallow fluff if youβre feeling crazy!

Thanks for the cornmeal tip!
Loving the crust on these!!!
Sweet potato fries are the greatest thing ever! I had just discovered the trick of coating them in cornstarch, but cornmeal sounds even better. Sometimes cornstarch can get a little gummy–especially when reheating. I bet the cornmeal gives the fries a beautiful crunch.
Wow these look absolutely gorgeous!! π
Oh I love sweet potato fries (probably more than regular French Fries)! I recently made some spicy sweet potato fries but have never heard of this cornmeal trick. I can’t wait to try it next time I get a sweet fry craving.
Oh these are perfectional. I love the addition of cinnamon…it just makes everything better.
Ok I had to check out the fries too. These pics are super yummy and the fries look gorgeous! I am now planning a meal around fries.
These sweet potato fries look much better than mine the last time I tried them. I think I am going to use this recipe next.
I loooove sweet potato fries! I can’t wait to try these at home!
Oh man, these are making my mouth water and I have no hope of making them for weeks. Le sigh. I’ll just live vicariously through you, then.
Those are some beautiful fries – I love the sweet potato variety π
Fries? Yes please π But I can honestly say I’ve never had a taste of sweet potato anything – unless we’re talking baby food but I can’t be sure of that since I don’t remember.
I would so date someone who smelled like french fries! π
I’ve been playing with sweet potato fry recipes so long, I’ve given up hope. But cornmeal just might be the trick to getting the elusive crispness! Thanks!
Seriously, and I’m serious. Those are my most favorite fries in the entire world and Earth. Seriously. LOVE THEM.
Hi Jessica, I was wondering if you have any tips for cutting those sweet potatoes evenly. I actually made sweet potato fries for the first time a week or two ago…I made “copycat” Bloomin’ Onion dipping sauce to dip the fries in and my husband and I are now addicted lol. My only problem is that they’re SO hard to cut and I’m terrified I’m going to slice my finger off, so any tips you have would be much appreciated!
I’ve never heard the cornmeal trick – great idea! Thanks.
How wonderful! We LOVE sweet potato fries – they’re almost as good as dessert!
I’ll have to try the cornmeal, haven’t heard of that. And the cinnamon – yum!
Thanks, Jessica!
Yes. Yes, I would like fries with that.
i make sweet potato fries all the time but never with the cornmeal crust. definitely gonna try that out!
I love sweet potato fries! In high school I dated a guy who worked for Arby’s. Jamocha shakes are really tasty.
The corn meal is a really great idea. These sound awesome.
