Add juice to the Instant Pot and place the trivet in the pot. Place the ham on the trivet and close the lid and the pressure valve.
Cook the ham on manual mode at high pressure:4-5 lb ham: 13 minutes + 20 minutes Natural Release6-7 lb ham: 18 minutes + 20 minutes Natural Release8-9 lb ham: 23 minutes + 20 minutes Natural ReleaseReminder: These cooking times are for a fully cooked bone-in uncut ham
After the cooking cycle has ended, allow the pressure to naturally release for 20 minutes as noted. After the 20 minutes, carefully release any remaining pressure.
Remove the ham and place it on a cutting board. Slice and serve or continue on with the glaze instructions.
If making the optional glaze (omit for Whole30 + Keto):
Once the ham has been removed from the Instant Pot, add the honey and dijon mustard to the leftover juices in the pot and stir to mix the ingredients.
Press the Saute button on the Instant Pot. While the juices start to cook mix the arrowroot starch with the water in a small bowl to make a slurry. Make sure the flour has completely mixed with the water.
Pour the slurry into the Instant Pot and mix well with the other juices. Cook, stirring frequently, for 5-6 minutes or until the glaze has thickened to your liking.
Press the cancel button on the Instant Pot. You can either use the glaze to brush all over the ham before slicing, drizzle it all over the ham slices for serving, or use it on the side for dipping pieces in.
This recipe and cooking times above are for a fully cooked bone-in, uncut ham.
The total "cook time" at the top of the recipe card is for a 4-5 lb ham. This total cooking time includes time for the Instant Pot to pressurize + the natural release + making the glaze. Follow recipe step #2 for the exact times to set the Instant Pot to based on the size of your ham.
Depending on the size of your ham and your Instant Pot, you may need to cut it in half to make it fit. Just cut the pieces as evenly as possible and follow the cooking times noted.
