Air Fryer Sweet Potato Fries are crispy on the outside, fluffy on the inside, and perfectly seasoned all over. So easy to make, these sweet potato fries are the best and make the most delicious side dish or appetizer – especially when dipped in homemade ranch dressing!
Crispy Air Fryer Sweet Potato Fries
If you’re looking for guaranteed crispy and delicious sweet potato fries, then the air fryer is the way to go. Made with WAY less oil than deep frying, they’re also WAY crispier than baked sweet potato fries (yes, I know, I said it). In other words, if there was ever a reason to purchase an air fryer it would be just for the fries. And maybe the Brussels sprouts.
Anyway, these are my favorite sweet potato fries ever. Completely guilt-free and good for you, you’ll never know the difference between deep-fried restaurant sweet potato fries and these air fryer sweet potato fries. Well, maybe you’ll be able to tell just a tiny bit, but the kids won’t!
How to Make Sweet Potato Fries in the Air Fryer
Start by preheating your air fryer to between 370-380 degrees F. Spray the inside with a light coating of non-stick cooking spray.
Prepare the sweet potatoes with a good scrubbing under cold water. Dry thoroughly. You can peel the skin or leave it on (I like to leave the skin on my sweet potatoes).
Cut the sweet potatoes into long and thin sticks (see below) and toss with a little oil and your favorite seasonings. I recommend a simple combination of salt, pepper, garlic powder, paprika, cinnamon, and sugar.
Cook the sweet potato fries in single, non-overlapping batches for best results. Shake the basket every 5 minutes and start checking every 1-2 minutes for doneness after 10 minutes.
Repeat until all of the sweet potato fries have been cooked.
How to Cut Sweet Potato Fries
Cut each sweet potato in half lengthwise to make two halves. Place the two halves cut-side (or flat-side) down onto the cutting board. Cut each half lengthwise into strips about 1/4-inch thick. Turn the strips on their side and slice any thicker strips so that they are each 1/4-inch thick on all sides.
The thinner they’re cut, the crispier (and faster) they’ll cook!
Tips and Tricks
- Longer isn’t always better: Try to purchase sweet potatoes that are about 5-6 inches in length. Sweet potatoes longer than 8-9 inches will need to be cut in half crosswise so that they can fit in the air fryer basket.
- Cut the potatoes evenly: This simply helps ensure that your potatoes will all cook in the same amount of time.
- Cook in batches: As tempted as you may be, it’s best not to overcrowd the basket. Cook them in a single layer.
- Turn and shake at least once: Flip, toss, shake, turn, just make sure the fries change position at least once during cooking.
- Keep them warm: Keep cooked sweet potato fries warm between batches by transferring them to a lined baking sheet and placing them in a preheated 200°F oven.
Frequently Asked Questions
I did not soak my sweet potato fries and found them to be perfectly crispy and delicious. With that said, it is known that soaking not only sweet potato fries but all types of potatoes, in water before cooking helps remove some of the excess starch. Should you choose to soak your sweet potato fries, do so in a bowl filled with cold water for 30-60 minutes. Dry well after draining.
Pick an oil with a higher smoke point. I used extra virgin olive oil, but avocado oil and canola oil will also work great.
The total time will depend on which model air fryer you are using, the temperature you are cooking them at, and how thick your fries have been cut. In general, plan on at least 10 minutes in an air fryer preheated to 380 degrees Fahrenheit.
If there’s too much moisture, your sweet potato fries will have a hard time getting crispy. Remember to dry your sweet potato fries before tossing them in oil and seasoning. Also, remember to cook them in a single layer. This will allow the hot air to circulate around, and crisp, the entire sweet potato fry. When they’re piled on top of each other, the sweet potato fries are going to steam each other as their moisture is released during cooking.
