The most common way to prepare a ham is by roasting it. If you choose to roast your ham, we recommend using a roasting pan. The size pan you’ll need depends on how big your ham is, but it should be able to fit comfortably without touching the sides. The depth or side height is also important; one that is too shallow increases the likelihood of hot splashes. For this reason, the side height should be about 3-4 inches for a standard-sized ham. In general, we recommend a roasting pan that’s 9 x 3 x 13.
If you don’t own a roasting pan, you can use a broiler pan or large casserole dish—even a baking sheet can work, although there may be hot pan drippings on the sheet, so use with caution. Of course, there are several advantages to using a roasting pan, namely that they’re big enough to house large hams and turkeys, meaning your meat will have ample room to cook evenly.
We also recommend using a meat thermometer. Most hams come pre-cooked, so you wouldn’t think you’d need a meat thermometer. However, with large hams it’s hard to tell when the meat is warm enough, and that’s when a meat thermometer will come in handy! Also, if you use a non-cooked ham, you’ll of course want to use a meat thermometer for food safety reasons.
