Good Questions. Pin it. Q: I'm a surgical resident and I'm frequently on call at the hospital with little time to spare in between cases, so I rarely get to sit down to eat dinner (even a quick one!). The only fridge is nowhere near the ORs, plus there isn't usually time to run down and heat up food to eat.
2 1/2 hours. Here's how: Preheat the oven to 325, place the ham on a rack in a baking dish with a little water in the bottom. Wrap in foil, bake for about 2 hours, or until th â¦ e internal temperature is 135 - 140 degrees.5 minutes per pound at 350 degrees. So, for a 7 lb. ham you are looking at just over an hour. If you aren't sure, cut a small slit on the largest part of the ham and feel if it's warmed through. Bone-in hams cook faster.
If you're starting with a fully cooked city ham, bake it in a 350 degree F oven for about 10 minutes per pound. If your ham is only partially cooked, bake it for 20 minutes per pound. To help keep your ham moist and juicy, place the ham cut-side down in a baking pan and tent it with foil. Every 20 minutes or so, brush the ham with glaze and baste it with the pan juices.
