Position Instant Pot trivet inside instant pot and place ham on trivet, cut side down and slices facing up.
1 4-5-lb boneless spiral sliced ham
In a large bowl, stir together pineapple and juice, mustard, brown sugar, and cloves. Add in beer and stir until well combined.
1-2 12 oz. bottle beer, 1 tablespoon dijon mustard, 1 20 oz. can crushed pineapple, ½ cup dark brown sugar, ¼ teaspoon ground cloves
Gently separate ham slices and pour pineapple/beer mixture over ham, in between slices.
Cook on manual pressure on High for 10 minutes, and allow pressure to release naturally.
Carefully remove ham from instant pot and cover loosely with foil. Turn instant pot to “Sauté” setting.
In a small bowl, stir together cornstarch with 2 tablespoon of water until cornstarch is fully dissolved. Add this slurry to the remaining liquid inside the instant pot and heat, stirring, about 5 minutes until thickened and reduced.
3 tablespoon cornstarch
Broiling (Optional)
Place ham in a broiler-safe baking dish on center oven rack and pour thickened glaze over the top. Sprinkle additional brown sugar on top of glaze, if desired. Position ham on center oven rack.
Position ham on center oven rack and broil 3-5 minutes or until top of ham is caramelized and browned.
Notes
Storing Leftovers: To store, you can place your ham, sliced or unsliced, into an airtight container or food storage bag. It will keep in the fridge for up to 3 days.
Freezing Leftovers: You can cut your ham into slices and pop it into a freezer bag, making sure to get some of that juice/glaze in there too to keep it moist! Then, be sure to squeeze out the air from the bag. I also like to add a second bag just to be extra sure it won't absorb any air from the freezer.
Slow Cooker Ham: Pour pineapple/beer mixture over ham and cook ham on low in the slow cooker for 3-4 hours. Thicken and reduce your glaze on the stovetop in a medium saucepan, rather than in the Instant Pot. Then, just transfer your cooked ham to a baking dish, pour thickened glaze over ham, and broil as normal.
