Typically, this crock pot honey ham recipe turns out moist and tender! However, if you overcook the mustard glazed ham, it can become dry. Be sure to remove it from the slow cooker as soon as it hits 140 degrees internally so it stays juicy. It's equally as important to let the ham rest before serving. If you serve it right away, that won't allow enough time for the juices to redistribute in the meat. Another way the ham can dry out is if you skip the mustard ham glaze. Using a glaze helps lock in the moisture so it stays juicy. So I don't recommend skipping the honey mustard ham glaze for this recipe.
