Exactly How Long To Cook A Pre-Cooked Ham - Tasting Table

"Thomas' most important tip is to "always cook to temp, not time," noting that "it doesn't have to be exactly 160 degrees Fahrenheit. Give or take 10 degrees is fine." Whether preparing your ham in a smoker or a low oven, the grillmaster advises that "225 to 250 [degrees] is perfect," adding that it "shouldn't take more than a couple hours.""

"While some options for warming your pre-cooked spiral-cut ham include cooking it in a roasting bag to keep it from drying out, Thomas recommends that you "cook it in an aluminum pan and apply a glaze after about 30 minutes."

If the ham finishes early, cover it with foil, wrap it in a towel, and use a microwave to keep it warm. Cook in an aluminum pan and apply a glaze after about 30 minutes to prevent drying. Powdered glaze packets work for convenience, and heat will caramelize the glaze.
