Coat the Ninja Foodi basket or air fryer basket with olive oil cooking spray.
Place the ham in the basket, you can also use aluminum foil and place it on this to avoid a messy basket if using the glaze.
Once the ham is in the basket, coat with brown sugar and top evenly with parsley and a coat of olive oil cooking spray.
Cook using the air crisp or air fryer function at 350* for 30 minutes.
If you are using the glaze, prepare the glaze while the ham is in the air fryer and add it in the last 5-10 minutes of cook time. Just carefully coat the ham with it and then finish cooking.
