2 cups packed brown sugar
1 (about 8 lb) bone-in picnic ham
1 can (6-oz) crushed pineapple, optional
Pineapple rings for serving, if desired
Place 1 1/2 cups of the brown sugar over the bottom to a slow cooker/crockpot. Place the ham over the brown sugar, flat side down. Trim bottom a little if needed to be able to fit lid over cooker.
Using your hands, rub the remaining brown sugar all over the ham. Add the pineapple, if using.
Place lid on cooker and cook on low for 8 hours. (This time is for a picnic ham. It is too long for a spiral sliced ham!)
