Sweet Potato Fries in the Air Fryer

by Chad Campbell

SWEET POTATO FRIES turn out great when you make them in the air fryer. Extra healthy in the air fryer and seasoned perfectly!

Sweet potatoes are a bit healthier than regular potatoes and they are a staple for many households. If this is you, then having a recipe for homemade fries made from sweet potatoes is an absolute must!

This recipe provides some garlic and some spice with a little bit of a breading to the sweet potatoes, and I absolutely love it!

These aren’t going to get as crisp as a traditional deep fried sweet potato fry, but the insides are soft and fluffy and they’re perfect for dipping!

I am a major french fry dipper. Whether it is fry sauce, ketchup, BBQ sauce, whatever…I just want a sauce to dip it in.

I played with a few sauces for this recipe and landed on a spicy dipping sauce you should try out. It would even be good on regular french fries.

How to make sweet potato fries in an air fryer:

  1. Wash your potatoes and slice them into thin fries, roughly a quarter inch thick.
  2. Add them to a large bowl full of water and soak for about 30 minutes. This removes extra starch from the outsides and prevents the fries from sticking together (making them crispier).
  3. Drain the potatoes and dry them well and place them back in a dry bowl.
  4. Drizzle the fries with avocado oil, and sprinkle with cornstarch, garlic powder, chili powder, and salt.
  5. Toss the fries to coat them.
  6. Air fry for 10 minutes and shake the basket after 3-4 minutes to cook them more evenly.
  7. For extra crispy fries, cook in batches so that you can do a single layer at a time. We go for less crispy fries to get them done extra fast.

Spicy dipping sauce:

This is super easy! Just whisk together the following ingredients in a bowl.

  • 3 tablespoons of mayonnaise
  • 2 tablespoons of sour cream
  • 3 teaspoons of sriracha

Questions about this recipe:

How can I make the fries crispier?

Don’t skip the step of soaking your fries in water. It does make a difference!
If you really want crispy fries, you’ll have to work in batches here. Place your fries in a single layer in the basket so the hot air can flow nicely around each fry. This will be the best way to get crispy fries. We tend to just pile the fries in and sacrifice a bit of the crisp for ease and speed, though.

Are sweet potato fries healthier than french fries?

Sweet potatoes are more nutrient dense and have a higher amount of fiber than white potatoes. Both have the same amount of total carbs.

We use and recommend the OMORC 6 qt air fryer. It has a larger basket, is dishwasher safe, and has lasted us for about 2 years of fairly heavy use.

After you have your air fryer you want to preserve it. Using a can of non-stick spray can damage your air fryer basket. You can prevent this by using a pump spray bottle for applying your preferred oil. For recipes calling for spraying on the food in the basket for example, we could use this to apply our avocado oil.

Air Fryer Sweet Potato Fries with Spicy Dipping Sauce

Yield: 2 servings
Prep Time: 10 minutes
Cook Time: 10 minutes
Additional Time: 30 minutes
Total Time: 50 minutes

Sweet potato fries are so simple in the air fryer! We serve these with a spicy mayo, but BBQ sauce is also a tasty dip for these fries.

Ingredients

For the Fries

  • 1 large sweet potato
  • 1 tablespoon avocado oil
  • 2 tablespoons cornstarch
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon chili powder
  • ½ teaspoon salt

For the sauce

  • 3 tablespoons mayonnaise
  • 2 tablespoons sour cream
  • 2 teaspoons sriracha

Instructions

  1. Slice the sweet potato into thin fries about ¼ inch thick.
  2. Add sweet potatoes to a large bowl full of water and let soak for 30 minutes.
  3. Drain sweet potatoes and dry well.
  4. Drizzle potatoes with avocado oil and sprinkle with cornstarch, garlic powder, chili powder, and salt. Toss to coat.
  5. Preheat air fryer to 380 degrees.
  6. Place sweet potatoes in the air fryer basket and cook for 10 minutes, shaking every couple of minutes.
  7. After ten minutes, check for doneness. Potatoes should be crisp on the outside and tender inside. 
  8. To make the dipping sauce, whisk ingredients together until well combined.
  9. Serve hot with sauce for dipping.

Notes

For more crispy sweet potato fries, you'll want to work in batches. Place a single layer of fries in the bottom of your air fryer basket and cook as directed. Repeat with the remaining fries. We tend to sacrifice a bit of the crispness and just cook the fries all at once to make things simpler and quicker.

You can also increase the heat to 400 and cook for an extra 1-2 minutes to crisp the fries up further, if desired.

We prefer to use avocado oil, but any oil that you like will work well here.
