Spray your crockpot with nonstick cooking spray. Place the ham in the center.
7-8 pound cooked bone-in spiral-cut ham
Brush the ham with the mustard.
2 tablespoons Dijon mustard
Rub the brown sugar all over the surface.
1 cup brown sugar
Pour the maple syrup and apple cider over the ham.
⅔ cup pure maple syrup, 1 cup apple cider
Cover and cook on low for 3 hours.
Once the ham is warmed through, set it on your serving platter and tent with foil.
Pour the juices from the crockpot into a medium pot and boil until the sauce reduces enough to coat the back of the spoon.
Brush, or pour, it all over the cooked ham. Enjoy!
