Question: Can I bake a frozen ham without thawing it first? Will it be safe?
Answer: Yes — as , you can cook frozen meat, including ham, in the oven without defrosting it first.
You’ll need to allow for some extra cooking time, though. It generally takes about 50 percent longer to cook a frozen ham than the time it takes for a fully thawed ham. So, for instance, a ham that would normally take 4 hours to bake if was fully thawed would take 6 hours if it was put into the oven frozen.
