Boneless hams are a bit denser and cook faster. A boneless precooked ham usually needs about 15 to 18 minutes per pound at 325°F. But again, trust the thermometer, not the clock.
Because they lack a bone, they heat more evenly. Score the surface in a diamond pattern before baking. This helps the glaze penetrate and gives you those satisfying crispy edges everyone fights over.
Practical Tip: If your ham comes with a packet of gelatin or a “flavor packet,” toss it. Seriously. That stuff is mainly salt and sugar. Make your own glaze for a genuinely superior result.
The Microwave Myth
Yes, you can technically microwave a precooked ham slice in thirty seconds. But a whole ham? Never. The microwave will turn it into a rubbery, steaming mess. The oven is your friend—be patient.
If you are in a genuine rush, use a slow cooker. Put the ham in, add a splash of liquid, and cook on low for 3 to 4 hours. The result is incredibly tender, though you lose the caramelized crust.
Fun fact: In the 1950s, canned hams were all the rage. They were marketed as “meat that never spoils” and were a Cold War pantry staple. Luckily, we have evolved.
