Wash the sweet potatoes.  Dry and stab 6-8 times per sweet potato with a fork in various spots throughout the sweet potato.

Drizzle the olive oil over the sweet potatoes and season with the sea salt.

Place the sweet potatoes on an air fryer rack or basket.  Make sure that the sweet potatoes are spaced out and not touching in the air fryer rack.

Cook at 400 degrees F for 40-45 minutes until a knife can be easily inserted and removed from the potatoes.

Serve topped with the butter, salt and pepper.  Enjoy!
