Crispy Oven Baked Sweet Potato Fries
This baked sweet potato fries recipe makes an amazing, delicious and healthy snack. They turned me into a sweet potato lover and now I make all types of sides with them, like roasted sweet potatoes, air fryer sweet potato cubes or these grilled sweet potato wedges. Yum!
While I like regular french fries or potato wedges, I love homemade sweet potato fries! They are crispy and seasoned to perfection. I love to dip them in fry sauce or burger sauce but there are lots of different condiment options that would taste great!
Recipe Ingredients
Baked sweet potato fries only require a few simple ingredients! Here is what you will to make these fries.
- Sweet potatoes: You will need 4 medium sized sweet potatoes. I like to buy sweet potatoes that aren’t super curvy and are a little longer in size vertically. It makes cutting them a little easier.
- Oil: Olive oil or canola oil can be used, I find that canola oil has slightly crispier results.
- Seasonings: I love the classic combination of kosher salt, pepper and garlic powder. Sea salt could be used in place of kosher salt.
- Optional: Cornstarch for coating your fries before baking.
Favorite Seasoning Ideas
There are so many different ways to customize your fries! I took the classic approach in this recipe, but below are a few of my other favorite spices.
- Spicy: Oil, kosher salt, pepper, garlic powder and paprika (or chili powder, cayenne pepper or chili seasoning).
- Cinnamon-sugar: Oil, kosher salt and cinnamon sugar.
- Rosemary: Oil, kosher salt, pepper, garlic powder and rosemary.
- Italian: Oil, kosher salt, pepper, garlic powder and Italian seasoning.
How To Make Baked Sweet Potato Fries
Achieving perfectly crispy oven baked sweet potato fries isn’t hard to do, just follow these tips and steps for best results. They are healthier than store-bought plus vegan and gluten-free!
- Cut sweet potatoes into matchsticks. Peel your sweet potatoes and cut off both ends. Slice in half horizontally, then cut halves vertically into 4 pieces. Slice again each piece vertically into 8 pieces then finally cut the sweet potato pieces into thin sticks, about 1/4″ inch thick and 3″ inch long.
- Soak fries in cold water: For the best extra-crispy fries soak uncooked matchsticks in large bowl with ice cold water for 30 minutes. Drain then pat dry and place in a zip-top bag with 2 teaspoons cornstarch and shake until evenly coated.
- Place on baking sheet: Place the sweet potato sticks in a single layer on a baking sheet lined with foil or parchment. Toss with olive oil.
- Bake: Oven bake your fries at 415 degrees F for 15 minutes. Mix together the seasonings and sprinkle evenly over the fries. Then flip them and bake an additional 10-15 minutes, or until crisp.
Expert Tips
- Thickness: Make sure to cut your sweet potatoes 1/4″ thick.
- Evenly sized: One of the main keys to making the fries crispy is to cut them into evenly sized matchsticks so that they all bake the same.
- Peeling: While I like to peel them for smoother fries, sweet potato skins are edible and add extra texture and nutrition. Some say it also makes them crispier!
- Cornstarch: Add the fries to a bag and shake 2 teaspoons of cornstarch on top so you have a thin coating.
- Oil: Use canola, grapeseed, sunflower or peanut oil for a crispier edge.
- Don’t overcrowd the pan: Make sure to line them in a single layer then flip the fries half way through baking to make sure each side is evenly crisp.
- Bake on a metal rack over a baking sheet: This will allow the hot oven air to reach all sides of the fries and as a bonus you will not have to flip the fries!

Serving Suggestions
These fries are so flavorful that you might find you don’t even need to dip them in anything! If you’re looking for yummy dipping sauce ideas, try ketchup, BBQ sauce, garlic aioli or ranch dressing. Sometimes we even use honey mustard sauce, guacamole or buffalo sauce!
If you’re doing the Whole30, you can make a compliant fry sauce by mixing together homemade mayo and Tessamaes ketchup. I use about 1/4 cup mayo and 1 1/2 Tablespoons ketchup.

FAQs
This is usually because you have cut your fries too thick. It’s better to actually cut them on the thinner side versus risking that they are too thick.
Another reason may be that they are not cut in uniform sizes. Uneven sizes can cause some fries to get done faster than others. Last, if you have overcrowded your pan, your fries will steam rather than get crispy.
Yes, this is actually my favorite way to cook these fries, you will just need to cook in 2 to 3 batches so the fries do not overcrowd the basket and steam them instead of getting them crispy. Preheat the air fryer to 380°F. Cook for about 12 minutes (turning half way) or until crisp.
That is the great debate! You can either soak and then toss them with cornstarch or toss the cut sweet potato fries with a cornstarch slurry. Just make a slurry with equal amounts cornstarch and water, add to a bag with cut sweet potatoes and shake to coat. Proceed with recipe as directed.
I have found that baking them at 415°F produces the best results in my oven. All ovens vary slightly and you may find that increasing your oven to 425°F produces crispier results. If you have a convection oven, even better as it will circulate the air inside the oven leading to fries that lightly browned and crisp.

I followed the directions explicitly and was so excited as I LOVE sweet potato fries. I soaked in water and used the cornstarch. They were SO SOGGY. I held my entree on warm in my 2nd oven. ALOT of work to be disappointed.
After soaking the fries must be patted dry – really well. Hope that helps!
Crazy undercooked. Needs double the time
Sorry to hear that the fries didn’t turn out as expected. All oven cook a bit differently, sounds like yours needed a bit longer.
The cutting of the sticks isn’t very easy, but I managed. Mine stuck to the foil after I baked 15 minutes, after the 30 minutes they hadn’t crisped. So, didn’t work for me, disappointing.
Hello, if using foil, I recommend spraying the foil really well. For crispier sweet potato fries, try soaking them in ice water first next time to remove excess starch.
Hi. Can the potatoes stay in ice water longer than 30 minutes. Just trying to time it for company ;-)
Thanks
That would probably work although remember to account for draining and patting them dry.
Great
Did all the steps and were soggy
Try following the extra crispy sweet potato fries instructions in the notes next time to ensure crispy results :)
SO GOOD!! I didn’t use the extra crispy hack of soaking them in cold water so they ended up a little soft, but I will do that next time. Nevertheless the seasonings were perfect and they turned out amazing!
So glad you enjoyed them!
We love sweet potato fries, even if they don’t get super crispy. But now my new oven has an air fryer feature and I’m trying it out for the first time! I’m so excited to see if we notice a difference!
Delicious! Thanks for the amazing recipe!
Wanting to make these to save throughout the week. Any clue on how they would save or freeze?
Hi! I haven’t tried freezing them, but if I were to meal prep these for the week, I would probably cut them into wedges and leave the skin on so they don’t go soggy. Then when I reheat them I would reheat in the air fryer, in the oven or stove top if you want to get them crisp. If you are microwaving them they will be soft.
Made these tonight and they were delicious!
Yay! Love to hear that. Thanks for sharing and giving a 5 star rating!
I love these sweet potato fries! So easy to make and they taste great. The spices are spot on, they are full of flavor.
Thanks for the tip about soaking then in water and coating in cornstarch. I made them in the air fryer, and they were amazing!
Glad you enjoyed the sweet potato fries!
These are delicious!!! I just added sweet potatoes to my shopping list so I can make another batch!
