Remove ham from refrigerator and let sit at room temperature for about 1- 2 hours. If desired, score the top of the ham, diagonally, about ¼ inch deep and 1inch apart.
Preheat your oven to 325 degrees F.
Place the ham cut- side down in a large roasting pan. Place foil paper over ham. This helps heat up the ham without drying it out until it’s time to glaze it.
Another option would be to add liquid. You can also add about ½ cup of wine or water to the bottom of the roasting pan to keep it super moist. While ham is roasting make the glaze.
In a medium pan, whisk together all of the Brown Sugar Glaze ingredients.
Let the butter melt, while stirring often, until brown sugar dissolves, about 1-2 minutes. Set aside.
Bake ham until the center registers 100 - 110degrees F (approximately 10-14 minutes per pound). Remove ham from oven, increase oven temperature to 400 degrees F.
While the oven is heating up, carefully unwrap ham from foil and discard foil. Brush with liquid from ham, use the liquid to add to the glaze to make it.
Then pour about 1/3 of the ham glaze all over the ham, brushing in between the cuts to coat every visible inch of the ham.
Return to the oven and bake uncovered for 12-15 minutes. Remove ham from the oven, again, add more juice from the ham carefully brush with more glaze about ⅓ more.
Return to the oven one last time, sprinkle with brown sugar, and bake for another 10 minutes or until brown sugar browns up.
Remove from the oven, let the ham rest about 10-20 minutes before slicing. Serve with remaining glaze.
