crispy Air Fryer Sweet Potato Fries

While I love the taste of homemade fries I don’t love the mess required to fry in oil so I rarely made them. Until now! These sweet potato fries cooked in the air fryer use virtually no oil, are full of nutrients, and have only a small amount of salt on them. 

We’ve made air fryer crispy potatoes, air fryer baked potatoes, and even air fryer frozen french fries and we loved every one of them. Now it’s time to make your own, homemade, sweet potato fries.

They are great side dish or you can enjoy them as a snack on their own. Just don’t forget your favorite dipping sauces!

how to make crispy Air Fryer Sweet Potato Fries

Ingredients You’ll Need

Here’s what to get:

  • Sweet Potatoes – You’ll need to cut them into fry shape using a sharp knife. I suggest about ¼ inch thick (about the size of your pinkie finger). 
  • Peanut oil – You really only need a small amount and could use canola oil instead.
  • Cornstarch – The cornstarch helps to add a bit of a crispy outside to the fries.
  • Seasonings – You’ll need to Kosher salt or sea salt, garlic powder, smoked paprika, and pepper.

Instructions

Here’s how to make these:

Step 1 – Cut the sweet potatoes. First, peel the sweet potatoes and cut them into strips approximately ¼ thick. They should be about  the length and width of your pinkie finger.

Step 2 – Soak the potatoes. This helps give you crispy fries! Next, fill a bowl with cold water and submerge the fries in it. Allow them to soak for at least 30 minutes or overnight.

Once they are done soaking, pour out the water and give them another quick rinse. Then pat them dry with a paper towel. You need to remove as much excess moisture as possible.

Step 3 – Season the potatoes. In a small bowl, combine the cornstarch, salt, garlic powder, paprika, and pepper. In a large bowl or a large bag, add fries and oil and toss together. Next, sprinkle in the seasoning and toss well until everything is fully coated.

Step 4 – Cook. Next, preheat the air fryer to 400 degrees F for 5 minutes.

Add the fries to the basket. You can stack up a little, but they should not be packed in together. They should be loosely stacked at most. If needed, cook in batches and keep cooked fries warm in the oven.

Cook for 18 to 20 minutes, stopping halfway through to toss the fries before continuing to cook.

Serve hot with your favorite dipping sauce or with your favorite meal.

Tips for the Best Results 

To make crispy fries in the air fryer, follow these two tips:

  1. Soak in water. Soaking removes excess starch. You should soak them for at least 30 minutes up until overnight in cold water. When done soaking rinse in cold water and pat dry. 
  2. Toss with cornstarch. Cornstarch makes a coating on the outside of the fries that help absorb any excess moisture. The cornstarch will get extra crispy as it is heated with a little oil. NOTE: If you are cooking in batches don’t oil and toss the fries until just before they are going into the air fryer.
  3. Cook in batches. This recipe makes 4 servings. Depending on the size of your air fryer you’ll most likely need split the cut potatoes into two equal batches and cook them that way so the fries can cook evenly.

Cooking Frozen Sweet Potato Fries 

If you are using frozen sweet potato fries, you can follow these steps.

First, preheat the air fryer to 400F for  5 minutes.

Next, place the frozen fries in the basket. You can slightly stack them, but do not pack them in.

Fry for 20 to 22 minutes at 400 degrees F.  Make sure to stop after 10 minutes and use tongs to toss the fries. You need to make sure that the fries in the middle make it to the top or bottom to cook evenly. 

Cook another 5 to 6 minutes and then toss again making sure to really move the fries around so the bottom fries cycle up to the top. Finish cooking for the remaining time.
