Prepare the Ham:
Place the fully cooked ham into the Crock Pot.
Make the Glaze:
In a small bowl, mix together brown sugar, pineapple juice, and Dijon mustard.
Cook:
Pour the glaze over the ham, ensuring it’s well-coated.
Cover and cook on Low for 4–6 hours, basting occasionally with the sauce to keep the ham moist and flavorful.
Serve:
Remove the ham from the Crock Pot. Slice and serve with the glaze spooned over the top.
