1 4-pound boneless ham
1 cup dark brown sugar
2 Tablespoons good Dijon mustard
Spray bottom and side of crock with vegetable spray. Sprinkle brown sugar over the bottom of the crock to cover. Unwrap ham, removing any mesh, and generously coat the cut side with Dijon mustard. Place the ham into the crockpot, mustard side down, top with lid, and cook on low for 4 hours. Turn off crockpot and allow ham to rest for 30 minutes before removing and slicing. Serve drizzled with warm juices.
