Instant Pot Meatballs - Form the meatballs. Add a cup of water or beef broth to the bottom of your IP, then set the metal trivet in the liquid. Arrange the meatballs on the trivet in 1 or 2 layers (you will have to do this in batches to use the whole recipe, or cut the recipe in half). Close and pressure seal the pot and set to cook on high with the meat/stew mode, for 7 minutes. Natural release for 5 minutes, then quick release for the remaining pressure. Place the meatballs on a lined baking sheet and follow step 5 in the recipe below to broil.
