These Baked Sweet Potato Fries are on the healthier side, and the salty-sweet-savory flavor of sweet potato fries just can’t be beat and are perfect for sweet potato lovers.
Why you’ll love this recipe:
Baked Sweet Potato Fries have to be one of the most underrated side dishes to serve with your favorite burger. There is no secret ingredient to make this great recipe, where the sweet potatoes do all the heavy lifting with only a handful of simple ingredients.
Plus, the good news is that sweet potatoes aren’t even all that bad for you. They don’t have the excess starch like some other side dishes, and are still perfectly crispy fries for a tasty appetizer, especially if you bake them rather than deep-frying the sweet potato fries.
Ingredients Notes:
- Sweet potatoes: Wash, dry, and peel the raw sweet potatoes
- Oil: For the best results, use either olive oil or avocado oil
- Seasoning: Use a combination of kosher salt or sea salt, black pepper, or garlic salt
- Cornstarch: Adding in cornstarch will help give the fries a nice crunch on the outside
How To Slice Your Sweet Potato Into Fries:
The best results be sure to try and cut your potatoes uniformly. Whether you like thin fries or thicker fries, the key is keeping them all cut to the same size and adjusting the baking time accordingly.
I like to slice the sweet potatoes lengthwise to keep the fries long, and depending on the thickness of the potato, you will want to slice them into 1/2 inch sections, normally getting 3-4 oblong slices.
Then cut again lengthwise, but this is where you can determine how thick you want your fries. Normally, ¼ inch to ½ inch is a good thickness for making this sweet potato fries recipe.


How to Make Baked Sweet Potato Fries:
Preheat oven:
- Preheat oven to 450℉.
Prep the large sweet potatoes:
- Wash and peel sweet potatoes.
- Cut sweet potatoes into fries or wedges.
Season sweet potatoes:
- Place cut sweet potatoes in a large ziplock bag and add the rest of the ingredients to the bag.
- Seal the plastic bag and shake until all of the sweet potatoes are evenly coated.
Bake sweet potato fries:
- Pour contents of the bag in an even layer onto a baking sheet lined with foil or parchment paper and spray it with nonstick cooking spray.
- Bake for 20 minutes, flipping halfway through, or until browned on the outside to your liking.



Serving Suggestions:
- Garlic powder
- Chili powder
- Chili lime powder (the Trader Joe’s seasoning is great)

Frequently Asked Questions for Making the Best Sweet Potato Fry Recipe:
I like to use either olive oil or avocado oil when making these crispy sweet potato fries. These oils hold up better at a high temperature, avocado oil especially with a higher smoke point.
While it is not necessary to soak the potatoes in a small bowl of cold water before frying, if you love super crispy baked sweet potato fries as it does remove the extra starch from the sweet potatoes fries.
However, it does add extra steps to this simple recipe. Just be sure to dry the sweet potato pieces on a piece of paper towel afterwards.

Thanks so much for all these recipes. Your meals are amazing!!
It seems like sweet potato fries are somewhat healthier compare to normal fries. Thanks for sharing.
Love sweet potato fries! I buy them in frozen food section regularly. I’m going to try this recipe so I can make them fresh when I want some. I’m sure it’s much better… Tks!
I made these tonite as a side for dinner. They turned out perfect! Even tho some were a little crispier it was a nice surprise. The taste was amazing! Little sweet, little salty. I will definitely make these more often! Thanks for the recipe 🙂
Okay so I started making these and then read the reviews and got super nervous! But they turned out AMAZING. They were cut thick so maybe that’s why they didn’t burn. I also made sure to check on them every 15 minutes and turn them often.
Rinse the potatoes and pat dry first before mixing in all the ingredients.
I’ve read some of the earlier comments, and agree, but when I made them from this recipe, I had already cooked sweet potatoes in several different ways and knew that they are much faster to cook than regular potatoes, so I did them for 12 minutes at 400 degrees and they were fine. But I do find it hard to believe that anyone who had made them before would suggest 40 minutes. Perhaps it was a typo or a momentary brain flip, because your recipes are normally bang on!
But I did enjoy them … Knowing that cooked, they are softer than potatoes means no surprises with the end product.
I tried to do this recipe and just couldn’t. I bought the raw sweet potatoes from the super market and washed them (as we do in Mexico with fruits and vegetables) and tried to cut them as french fries… but it was SO HARD! The sweet potato is very hard to cut, I don’t know if this is like it’s supposed to be (and I should buy a bigger / sharper knife) or should I bake them first for them to be easy to cut?
Anyway I just put them in the oven now, the whole thing, will try bake them a little and then cut them. Or maybe it is because the sweet potatoes in Mexico are different?
Thank you!
Love this recipe! They’re in the oven and it smells delicious. We added paprika to the seasoning and it spiced it up even more. Thank you! 🙂
