Place the trivet with the handles in an 8 quart instant pot.
Pour 1 cup water into the instant pot.
Lay out a large piece of foil on the counter.
Lay out a large piece of foil. Place a 5–8 pound spiral ham in the center and fold up the sides to create a bowl.
Rub 1 cup brown sugar over the ham. Pour ½ cup maple syrup (or honey) and 1 cup pineapple juice over the top, keeping everything inside the foil.
Secure the foil warp around the ham.
Place the wrapped ham on the trivet inside the instant pot.
Seal the lid and cook on high pressure for 2 minutes per pound of ham plus an additional 10 minutes (for example, a 7 lb ham cooks for 24 minutes).
Allow the pressure to release naturally for at least 10 minutes, then perform a quick release.
Ensure the ham reaches an internal temperature of 145°F.
Carefully remove the ham from the instant pot, slice, and serve warm. Enjoy!
Notes
I added 10 minutes to the cook time as I used heavy duty foil to wrap the ham. If tin foil is used instead, only add 5 minutes to the cook time instead of 10 minutes.
