What you’ll need
This sweet potato air fryer recipe requires just a handful of pantry staples.
- Sweet potatoes: Choose medium-sized, evenly shaped ones for even fries.
- Olive oil: Use light olive oil or any neutral cooking oil like coconut, avocado, or canola oil.
- Seasoning: feel free to stick to just salt. Or use a mix of salt, black pepper, garlic powder, onion powder, and smoked paprika for flavorful air-fried sweet potatoes.
Instructions
Peel and slice: Start by rinsing and peeling (optional) the sweet potatoes.
Then, slice a small piece off the end of each potato, so they can stand upright on your counter. Using a sharp knife, cut slices ¼-½-inch wide (based on how thick you want the fries to be). Then, stack 2-3 slices on top of one another and slice them into ¼-½-ich fries across, too. Repeat with the remaining potato until you have all your sweet potato fries.
To simplify this process, use a mandoline with the fries blade or a “chipper”/ fry cutter tool.
Then rinse and dry them thoroughly using clean paper towels.
Season: Mix the oil and spices, drizzle them over the fries, and toss them until well-coated. Alternatively, use an oil spray to lightly coat the fries with just enough oil to help the spices adhere. Then toss them with the spices in a large mixing bowl.
For the crispiest results, it may be best to leave the salt out of the seasoning until after air frying the sweet potato fries.
Air fry: First, preheat the air fryer to 380ºF/195ºC. Then, place the sweet potato fries in your air fryer basket in a single layer without much overlapping. If you have lots to make, do so in batches.

- Make sure to shake the basket: This ensures the air fryer sweet potato fries cook evenly on all sides.
- For the crispiest fries: The thinner they are, the crispier they’ll become when air fried.
- Optional add-ins: Feel free to add some cayenne pepper or chili powder for heat or a sprinkling of freshly grated parmesan (added at the end).
