How to Make the Sweet Potato Fries
Make these fries in minutes by either of two methods with a few ingredients:
Ingredients
Be sure to see the recipe card below for the full listing of ingredients, instructions, notes, and estimated nutritional information.
- Sweet Potato – Make sure your potato has been scrubbed clean.
- Olive Oil – you can also use canola oil or avocado oil
- Sea Salt – I prefer to use sea salt in this recipe. You can use your favorite type of salt.
- Cornstarch (Optional) – While optional, just 1/2 teaspoon of cornstarch can help to make the outside of the fries even crispier. Toss the fries in it before you add the olive oil if using.
- Seasonings (Optional) – I’ve included a few recipe variations you may enjoy later in the recipe. If using any of these optional seasonings, use them after the fries have cooked. This prevents the seasonings from burning.
Recipe Variations
Stone House Fries – Sprinkle cooked fries with 1/4 teaspoon Stone House Seasoning.
Spicy Sweet Potato Fries – Similar to my spicy sweet potato wedges, you’ll add 1/4 – teaspoon each chili powder and black pepper to the cooked fries and toss.
Parmesan Sweet Potato Fries – Sprinkle fries with 1/4 cup grated parmesan and 1/4 teaspoon Stone House Seasoning right after you remove them from the air fryer or oven.
Cinnamon Sugar Fries – Sprinkle fries with 1/4 teaspoon ground cinnamon and 1 teaspoon sugar once you remove them from the air fryer or oven.
Step-by-Step Instructions
- Prep and slice. Peel the potato, cut off the ends, and then slice the sweet potatoes lengthwise into 1/4-inch slices. Then, turn the slices onto their flat sides so that on the cutting board for easier slicing. Slice into uniform-sized fries for even cooking. Uniform slices are essential as they will cook more evenly, and thick potato slices won’t get as crispy.
- Toss in cornstarch (if using). The cornstarch is optional but does help to crisp the fries even more. Make sure the potato slices are patted dry. Then, put them in a plastic bag with the cornstarch. Shake until all the slices are coated.
- Drizzle and toss with oil. Then, place the uncooked fries on a baking sheet. Drizzle with the olive oil and add the salt. Toss to make sure that all of the fries are coated.
- Cook – Two Methods (to follow). Then, cook according to the instructions for either the air fryer or the oven-baked sweet potato fries based on your preference.
Air Fryer Sweet Potato Fries
- Preheat the air fryer to 400º F.
- Arrange the potatoes in a single layer in the air fryer basket.
- Once the air fryer is heated, cook for 8 to 12 minutes, tossing as needed to ensure that all the fries cook uniformly. Extend the cooking time until all are cooked evenly. (Note: My air fryer takes 10 minutes, but the time will depend on the size of the fries and your particular air fryer.)
- Serve warm.
Oven Baked Sweet Potato Fries
- Preheat the oven to 425º F.
- Arrange the potatoes in a single layer on a baking sheet. Do not put more than a single layer.
- Once the oven is heated, cook them for 20 minutes. Turn the fries using a metal spatula and cook for 10 – 15 more minutes. Watch the fries closely at this stage so they do not burn.
- Serve warm.
Recipe Tips
- Slice the sweet potato into small, uniform-sized slices so that they cook evenly and crispy.
- Toss the potato slices in cornstarch before tossing in oil to make the outsides of the fries extra crispy!
Storage Tips
To refrigerate. Place completely cooled fries in an airtight container. Store in the refrigerator for up to 5 days. To reheat from the refrigerator, place in the oven or air fryer preheated to 400º F for about 5 minutes until crisp.
To freeze. Allow fries to completely cool. Place in an airtight container and in the freezer for up to 2 months. Reheat in the oven or air fryer preheated to 400º F for about 10 minutes until crisp.
Frequently Asked Questions
There could be too many fries on one baking pan. Make sure the fries are in a single layer with a bit of space between each piece for the most crispy fries.
Also, make sure that the slices are uniform, 1/4 inch slices and not sliced too thick. Make sure the slices are DRY before you toss them in cornstarch and/or oil. Wet potato slices may steam in the oven instead of getting crispy when baked.
Sure! As long as the potato is scrubbed clean it is fine to leave a bit of the skin on the fries to cook them.

Robyn,
Our favorite restaurant, Sully’s Bistro & Bar, in Suquamish, WA, serves a delicious chipotle dipping sauce with their sweet potato fries, that is heavenly. I think that it is mayo-based, and I could eat it with a spoon. I love your recipes every day. I give your cookbooks as gifts. Have a great day!
Ed
Thank you, Dr. Holmes. I’ll have to make a sauce like that one day. Have you tried the sweet potato fries with my Avocado Dip (Avocado Crema)? If you do try it, let me know how you like it. I appreciate you giving my cookbook as gifts.
These sound simply delicious! Pinning this!!
I love that these fries look so good & that their healthy! Its not all the time that i bump into a healthy recipe that looks to die for! Going to try this recipe! Thank you!
My family loves sweet potato fries. Years ago, when we were first discovered them, the restaurant served them with honey. Now, we like them so much that we skip the honey and just eat the same as the baked them.
After you cook them try a little Chinese 5spice on them w/ a little brown sugar , or brown sugar and cinnamon. Yummy for your tummy
