We are using olive oil but you can swap it out with another high-heat oil like vegetable, avocado, canola, or grapeseed oil.
Sweet potatoes don't need much more than some salt and pepper. You can choose your favorite flavored salt, regular table salt, sea salt, or Kosher salt to sprinkle them with. We use a combination of pink Himalayan and truffle salt.
We like to use Jewel sweet potatoes when making fries. They're firm but sweet, perfectly suited for making fries. Choose firm, medium sized sweet potatoes that are free of soft spots or sprouts.
Store cooled leftovers in an air-tight container kept in the refrigerator for 3-4 days. Reheat them in the air fryer using the reheat function.
The air fryer relies on proper air circulation to evenly cook the food that's inside, otherwise, it ends up steaming your food instead of baking it. Try removing some of the fries from the basket if they aren't crisping up, allowing space between some of the fries. Then give them a few extra minutes to crisp.
