How to Cook a Holiday Ham: Easy Tips for a Juicy, Crowd-Pleasing Centerpiece

Hey there, folks! I’m your go-to public holiday assistant, and I’ve got a question that’s been popping up a lot lately from readers like you: “How do I cook a holiday ham without drying it out?” Trust me, I get it. The holiday ham is the star of the table, and nobody wants to serve a dry, salty brick. So let’s roll up our sleeves, preheat that oven, and break it all down step by step.

First things first — let’s talk about what kind of ham you’re working with. If you bought a spiral-cut ham, that’s already fully cooked, so your main job is just to warm it up gently. Same goes for a city ham (the wet-cured kind you usually see in stores). A country ham, on the other hand, is dry-cured and needs soaking and simmering before baking. For most of us hitting the grocery store around the holidays, the spiral-cut or bone-in city ham is the way to go, and that’s what I’ll focus on here. It’s practically foolproof if you keep a few simple things in mind.

Alright, let’s get into the real deal. The secret to a moist holiday ham is low and slow heating — not blasting it at 350°F for hours like a turkey. Preheat your oven to 275°F to 300°F. Pull the ham out of the fridge about 30 to 60 minutes before cooking so it loses that chill. This helps it warm through evenly. If your ham comes in one of those plastic trays with a glaze packet, set that aside for later. And don’t even think about throwing that glaze on right away — it’ll burn into a sticky mess before the ham is even close to warm.

Now, before you pop it in the oven, take a sharp knife and score the top of the ham in a diamond pattern, about a quarter-inch deep. This isn’t just for looks — it lets the glaze seep into the meat and gives those edges a nice, chewy caramelized bite. If your ham has a rind or thick fat cap, trim it down to about a quarter-inch of fat, leaving that layer intact to keep the meat juicy underneath. Some folks like to stud the ham with whole cloves at the intersections of the diamonds, and honestly, that’s a classic move that smells amazing. Totally optional, but kinda fun.

Here’s the part where a lot of people mess up: don’t cook the ham uncovered and dry. Place it cut-side down in a roasting pan with about a cup of water, apple juice, or even chicken broth in the bottom. That liquid keeps the air moist and prevents the ham from drying out. Cover the whole thing tightly with foil — or pop it into a roasting bag if you have one. For a spiral ham, cover it tightly with foil but be gentle so the slices don’t separate. Then slide it into the oven and plan on roughly 10 to 15 minutes per pound. That usually lands around 1.5 to 2 hours for a 10-pounder. The internal temp should hit 140°F at the thickest part — remember, it’s already cooked, so you really are just reheating it. And if it hits 140°F a little early, that’s totally fine. Don’t panic and crank the heat.

With about 30 minutes left, pull the ham out and crank the oven up to 400°F. Brush on that glaze — whether it’s the packet, or better yet, a homemade mix of brown sugar, honey, Dijon mustard, and a splash of orange juice. That sweet-tangy combo is unbeatable. Pop it back in uncovered and let it caramelize for those final 20 to 30 minutes. You can baste it every 10 minutes with the pan drippings to build up that gorgeous, glossy crust. The sugars will bubble and darken, and the whole kitchen will smell like Christmas morning.

Here’s one more tip that’s non-negotiable: after you pull the ham out, let it rest for at least 15 to 20 minutes before slicing. I know, I know — everyone’s eyeing it like hungry wolves, but if you cut it right away, all those juices run straight onto the cutting board and leave you with dry meat. Resting lets the juices redistribute, so you’ll get tender, juicy slices every time. For a spiral ham, just follow the pre-cut lines with a thin knife to separate the slices cleanly. For a bone-in ham, carve across the grain, working from the shank side first.

Questions related to how to cook a holiday ham

How long do I cook a spiral ham? As a rule of thumb, a fully cooked spiral ham needs about 10 to 15 minutes per pound in a 275°F oven, covered, until it hits 140°F internally. Then glaze and crank the heat to 400°F for the last 20 minutes. That’s the sweet spot. And if you’ve got a smaller half-ham, aim closer to 10 minutes per pound.

Should I put water in the bottom of the pan? Absolutely. Adding a cup or two of liquid (water, apple juice, broth, even cola — seriously, it works) creates steam in the pan and keeps the ham from drying out. Plus, those drippings make a killer base for a pan sauce or gravy. Don’t toss them!

What’s the best glaze for a holiday ham? There’s no single right answer, but a classic brown sugar and honey glaze with a little mustard and cinnamon is a crowd favorite. Some folks swear by maple syrup and bourbon, others use pineapple juice and cloves. The trick is to use something with sugar, a bit of acid, and a little heat — that balance cuts through the salty ham.

Do I have to cover the ham while baking? Yes, for most of the baking time. Covering traps moisture, so the ham steams and heats through evenly. If you skip the cover, you’ll end up with a tough, dry exterior and a center that’s still cold. Save the uncovered baking for the glaze stage, and even then, keep an eye on it so the sugar doesn’t burn.

Can I cook a frozen ham without thawing it first? Technically you can, but I wouldn’t recommend it. A fully cooked frozen ham will need about double the time, and it’s really easy to end up with overcooked edges and undercooked middle. Give it a few days in the fridge to thaw, or if you’re in a pinch, float it in cold water, changing the water every 30 minutes. Slow and steady wins this race.

So there you have it — the simple, no-stress path to a juicy, glazed, holiday-worthy ham. The golden rules: keep the heat low, keep it covered, don’t glaze too early, and always let it rest. Follow those, and you’ll be the hero of the buffet table.
