Yes—you can cook a spiral ham in a slow cooker, and it stays juicy while the glaze melts into every slice. Most spiral hams heat through in 3–4 hours on LOW or 1½–2½ hours on HIGH, until the center reaches 140°F (60°C).
Add a splash of water, juice, or broth to the bottom, then cover and keep the lid closed so it warms evenly. Brush on glaze during the last 30–45 minutes, and let the ham rest 10 minutes before slicing so the juices settle.
