One recipe involves placing 1 1/2 cups brown sugar in the bottom of the slow cooker and adding the ham flat side down. Rub 1/2 cup brown sugar on the ham, and cook on low for eight hours. Add 1/2 cup pineapple juice before the brown sugar for a variation.
Another option for slow cooker ham is to make 1/4-inch deep cuts in the ham about 1 inch apart in a diamond pattern. Place the ham in the slow cooker and pour the desired sauce over the ham. One sauce variety is honey mustard made by mixing 3/4 cup light brown sugar, 3/4 cup honey, 1/2 cup Dijon mustard and 1/4 cup apple juice. Maple-brown sugar sauce is made by combining 1/2 cup honey Dijon mustard, 1/2 cup real maple syrup and 1/2 cup brown sugar.
Use the slow cooker to create a ham and potatoes dish using chopped ham and thinly sliced potatoes. Put 3 pounds thinly sliced potatoes in the slow cooker, then mix with 1 cup shredded Cheddar cheese, 1/2 cup chopped onion and 1 cup chopped, cooked ham. Stir together one can condensed cream of mushroom soup and 1/2 cup water and season with 1/2 teaspoon garlic powder and 1/4 teaspoon salt and pepper. Pour it over the potato and ham mixture, and cook on high for four hours.
