Crispy Air Fryer Sweet Potato Fries in 20 minutes. Yes please!

Sweet potato fries are my absolute favorite, and I’m still amazed how fast they come together in the air fryer. We’re talking 15-20 minutes—faster (and way better) than those sad frozen ones from the store. Air frying makes them crispy on the outside and tender in the middle without frying in oil.

Serve crispy air fryer sweet potato fries hot with homemade ketchup, ranch, or your favorite dipping sauce!

How to make Air Fryer Sweet Potato Fries:

Prep and season: Peel the sweet potatoes and trim the ends. Slice them lengthwise into ¼ to ½-inch thick slabs, then cut into matchstick-sized fries. Try to keep the pieces as uniform as possible for even cooking. Season sweet potato fries with salt, garlic powder, cayenne pepper, cinnamon, and cornstarch (cornstarch helps them crisp up!).

Air Fry: Drizzle or spray the fries lightly with oil and toss to coat. Air fry at 400°F (180°C) for 10-14 minutes, tossing once or twice during cooking until crispy and golden brown.

Note: Cook time can vary based on how thick your fries are and the type of air fryer you use. Thicker fries may take longer. When in doubt, start checking around 8 minutes to avoid overcooking.

These are amazing! I make them almost everyday! So easy and delicious. I just try to not have black pieces so its healthier. (It’s hard to do but bc I eat them so often, less black is better.)

I was skeptical of the seasonings because of the cinnamon. So, I made one batch using these seasonings and one batch using the seasonings from your regular sweet potato fries recipe. I actually loved this one better. And I used that dipping sauce too. Yum.

I have tried numerous sweet potato fries some in the oven and the air fryer. This by far I would say is these one. I liked the directions and the combination of spices. The hubby loved them too. Thank you
