Most hams you buy at the store are already fully cooked. Yes, you read that right. That majestic ham has already survived the fire, like a porky phoenix. So your job isn't to “cook” it to safety—it’s to reheat it to glory without turning it into a salty, dried-out shoe leather.
Set your oven to 325°F (163°C). This is the Goldilocks temperature—not too hot (which makes it weepy), not too cold (which makes you wait forever). Science has spoken.
But Wait—There’s Math
Here’s where you earn your honorary chef badge. You want the internal temperature of the ham to hit 140°F (60°C) if it’s pre-cooked. 145°F (63°C) if you’re feeling daring and it’s a fresh, raw ham (but honestly, who buys those by accident?). Use a meat thermometer—please. Guessing is for poker, not pork.
Imagine your ham is a slow, sleepy bear waking up from hibernation. You want it warm all the way through, not scorched on the outside and frozen in the middle. 325°F is the perfect pace. In fact, the USDA says you can even go as low as 250°F if you have three hours and the patience of a monk. But why would you do that to yourself?
