Rinse the pork shoulder under cold water and pat dry
Season all sides of the pork shoulder with your favorite bbq or pork rub.
Place the pork shoulder in a zip-top bag and allow the spices to dry brine or marinate the pork in the refrigerator for up to two days (optional)
Place the pork shoulder inside of the air-fry basket fat side down
Re-season any areas where seasoning has fallen off (optional)
Find one of the thickest parts of the pork shoulder and insert the thermometer probe into the center of that area so that it gets an accurate reading
Preheat your Ninja Foodi Grill to 225F on the roast setting
When the Ninja Foodi Grill is preheated place the pork shoulder and basket inside of the grill
Insert the other end of the probe into its receiver in the Ninja Foodi Grill and set the temperature to 200F
When the pork shoulder reaches an internal temperature of 115F flip the meat so the fat side is up
Continue roasting until the meat reaches an internal temperature of 200F
Remove the pork shoulder from the Ninja Foodi Grill and allow it to rest covered with foil for 10-15 minutes before slicing
