To speed up the recipe, use cooked chicken—leftover or rotisserie works great. You can also try my Crockpot Whole Chicken or Instant Pot Shredded Chicken. For the Instant Pot, substitute raw chicken with 2-3 cups of cooked chicken and cook on high pressure for just 5 minutes. On the stovetop, swap in cooked chicken and simmer for about 20 minutes, or until the potatoes are tender. For quicker results, pre-warm your chicken broth in the microwave before adding it to the pot.
