Add the ham to the slow cooker. Spread over the mustard. Pat over the brown sugar. Now pour over the pineapple with it's juices.
Cover and cook on LOW for 5-6 hours. Don't open the lid while it cooks, so heat doesn't escape.
Slice and serve with pineapple and juices.
How much ham per person?If the ham has a bone in it, you will need to figure a 1/2 pound per person if it is boneless, 1/3 pound per person. If you are serving turkey as well, you can cut back even more. It is always nice to have leftovers or send leftovers with your guests, so don't stress too much if you buy a larger ham.Can I freeze the leftover ham?Yes, place the ham in ziplock bags, squeeze out the air. Freezer for up to three months. Thaw in fridge. Use in your favorite recipes.Can I use honey instead of brown sugar?Use 1/4 cup honey in place of the brown sugar for a different flavoring.My ham will not fit in my slow cooker! If your ham is too large, cut off the smaller end portion. Use that extra ham in a another recipe.How to reheat ham:
You can reheat the ham either in the microwave if you are heating up small amounts like slices.
Another option is to reheat the slices in a frying pan. This creates a different flavor by caramelizing the glaze.
If you have a large amount of ham to reheat you can heat it in the oven, place the ham in a baking dish and add about a 1/2 inch of water. Cover with foil and bake at 325 degrees for 15 minutes per pound.
