Start by washing your sweet potatoes. Then dry them off.

Slice the sweet potato with slices (either use the tool or make the slices with a sharp knife about 1/4 inch.) Use olive oil and grease the potato, and add some sea salt. Place the potatoes into the air fryer basket, and set the temperature to 350 degrees F for 20 minutes. (air fryer setting)

After 20 minutes, brush melted butter on top, and air fry for another 20 to 30 minutes at 350 degrees F. (air fryer setting). Remove when fork-tender.

While the potato finishes cooking in a small bowl, mix the melted butter with brown sugar, and when the potatoes are done, fill the cavities with the brown sugar butter mixture right before serving.

Plate, serve, and enjoy!
