Remove ham from any packaging, wrap it completely in foil paper, and place it in the air fryer basket.
Air fry at 300 degrees Fahrenheit for 15 minutes.
Meanwhile, prepare the glaze by whisking brown sugar, pineapple juice, cinnamon, nutmeg, and salt in a medium-sized saucepan over medium heat. Bring mixture to a boil and immediately remove from heat.
After 15 minutes, carefully open the foil and brush ½ of the glaze on the ham, brushing in between the slices. Cover the ham with the foil and cook for an additional 15 minutes at 300 degrees Fahrenheit.
Once the time is up, remove the foil paper and pour the remaining glaze on top.
Optional step: If you want a little char on your ham edges, continue to cook ham, uncovered, at 400 degrees for 3-5 minutes.
