How to Make Sweet Potato in the Air fryer

With less than five minutes of prep time and 35 of cooking time, these air fryer sweet potatoes for three make a great weeknight meal. 

Start this simple recipe with some basic prep. Wash your sweet potatoes, dry them really well. Then carefully pierce them with a fork to prevent them from bursting out of their skin while being cooked.

Next, spray or brush the whole sweet potatoes with avocado oil or olive oil, if desired. This will create a crispier outside once cooked. If desired, sprinkle with a little kosher salt.

Then, place the sweet potatoes in your Air Fryer basket in a single layer; the rest is almost entirely hands-free!

Do not preheat the air fryer! Simply set the air fryer to 390 degrees for a cook time of about 35 minutes. The skins will crisp better if you start it as soon as you place the sweet potatoes in the basket.

You will know your sweet potatoes are done when they start to ooze a bit of juices from the holes made with your fork. Or do a simple squeeze test with a hot pad, if they give to gentle pressure they are done!

Carefully remove the fluffy sweet potatoes from the air fryer basket and serve with your favorite toppings—And that’s it!
