An easy slow-cooker ham recipe is Pillsbury's Slow-Cooker Maple-Brown Sugar Ham. The recipe takes about 10 minutes to prepare and uses only three other ingredients besides the ham.
To make Pillsbury's Slow-Cooker Maple-Brown Sugar Ham, first make slices in the top of a 5- to 6-pound fully-cooked boneless ham about 1-inch apart and 1/4-inch deep. Place the ham in a slow cooker coated with cooking spray. Whisk together 1/2 cup honey Dijon mustard, real maple syrup and brown sugar, then pour over ham. Cook the ham on low for three to four hours, then remove the ham and cover loosely with aluminum foil. To serve the ham, slice and pour the remaining juices from the slow cooker over it.
For another easy slow-cooker ham recipe that uses cola, first cut a diamond pattern in a 3- to 4-pound boneless fully-cooked ham by making 1/8-inch deep diagonal cuts one way, then the other way. Mix together 1/2 cup brown sugar and 1 tablespoon mustard until a paste forms. Press the paste into the cut parts of the ham. Place the ham in the slow cooker and add in 2 12-ounce cans of cola, making sure not to pour the soda directly over the ham. Cook the ham on low for seven to eight hours.
