About these air fryer sweet potato fries:

Why buy expensive frozen sweet potato fries when you can easily make them from scratch in your air fryer? All you need are just a few ingredients and an air fryer.

A bag of a popular brand of sweet potato fries has stuff in it that will have you scratching your head in puzzlement. Why all the additives? Sweet Potatoes, Vegetable Oil (Contains One or More of the Following: High Oleic Canola, Canola, Sunflower), Rice Flour, Cane Sugar, Tapioca Starch, Corn Starch, Dextrin, Sea Salt, Spice, Salad Mustard Powder (Distilled Vinegar, Mustard Seed, Salt, Turmeric, Paprika), Gluconic Acid, Xanthan Gum.

I’ll choose wholesome (and cheap!) sweet potatoes, healthy olive oil, salt and pepper any day!

A sharp knife is helpful for cutting the fries because the thinner you cut them, the more surface area there is for maximum crispiness. A mandolin works great, too. Just watch the fingers!

  • Salt and pepper

Tips for the best sweet potato fries

  • Soak the cut sweet potatoes in a bowl of cold water for twenty minutes to remove some of the starch.
  • Dry the potatoes thoroughly. Dry equals crispy! Use a clean linen (lin-free) kitchen towel or paper towels to get the cut potatoes good and dry before frying.
  • Don’t overcrowd the fries in the air fryer basket. Allow room for the air to freely circulate. It’s much better to do the fries in batches so they have plenty of room to get crispy.
  • Watch closely towards the end of the cooking time. The fries tend to brown quickly once they get going.
  • Keep fries warm in the oven while you make multiple batches. Spread cooked fries on a wire baking rack placed in a sheet pan in a warm oven (175-200ºF). This will keep the cooked fries warm and crispy while you finish cooking the rest.

How to make these air fried fries your own:

  • Make sweet potato chips, chunks, or wedges. Keep in mind that thinner cuts will cook more quickly, and thicker cuts will take longer.
  • Prefer no oil? Just omit the olive oil and spray the air fryer rack lightly with cooking spray so the fries don’t stick.
  • Season the fries: Add garlic powder, onion powder, paprika, chili powder, or smoked paprika, to taste. Grated Parmesan cheese is good, too.
  • Looking for something a little different? Try Air Fryer Sweet Potato Hash with candied bacon
  • Rather have regular potatoes? Try Air Fryer French Fries or Air Fryer Potatoes.

Make-Ahead Ideas

To get a head start on things, cut sweet potatoes ahead of time and soak in water overnight. Drain and dry well before air frying.

Or prepare sweet potato fries completely and freeze in storage containers or freezer bags until ready to use. Reheat as directed.

Storage Tips

Air fryer sweet potato fries can be stored in the fridge, wrapped well, for three to four days. You can also freeze fries for up to one month.

Reheating Suggestions

For best results, reheat sweet potato fries, whether frozen or refrigerated, in your air fryer. Preheat the air fryer to 350°F, and place the fries on the rack in a single layer. Reheat three to six minutes until hot and crispy. The cooking time will vary depending on whether the fries are frozen, and how thick the fries are.
