Best Answer: No, there is no need to cover it. Ham is already cooked, so you just have to heat it thru. Cook it in the oven at 250 for about an hour. It will not brown at that temperature. You don't have to cover the ham especially if you use a glaze, but if you want you could also use a deep enough pan for the ham and flip a cookie sheet over the top to act as a lid. NO it is not required at all and it will get noice and crusty just as ppl have said keep the temp low and dont overcook it.
The ideal internal temperature for a precooked ham is 148 degrees F because it ensures optimal tenderness. Many precooked hams do not come complete with glazes. Many people add a glaze to a precooked ham to render it even more delectable. The glazing process does not add to the baking time; however, the glaze is perfected by turning on the broiler for five minutes at the end of the baking process. Learn more about Meat.
