How to Cook a Delicious Ham

7. Glaze the Ham

Remove an unsliced, bone-in ham from the oven during its last 30 to 40 minutes to apply the glaze. For a pre-sliced ham, wait and apply the glaze when there are about 10 minutes of cook-time remaining. Remove the foil. Apply your chosen glaze liberally over the entire ham, allowing it to seep into the ham’s interior through the diamond-patterned cuts. Place the ham back into the oven to finish the cooking process. The heat should caramelize the glaze, not burn it. Remove the ham from the oven and allow it to rest for about 30 minutes before serving.
