Set the oven to 325°F and plan on 15 to 18 minutes per pound for a fully cooked bone-in ham that’s only being reheated to a juicy 140°F internal temperature. Score the fat cap in a diamond pattern, then brush on a brown sugar or maple glaze during the final 20 to 30 minutes so the sugars caramelize without scorching.
This guide covers everything from picking out the right shank cut to glazing, hitting a safe 140°F internal temp, and carving without drying it out,everything home cooks need for a moist, flavorful holiday ham.
What a Shank Portion Ham Actually Is
The shank portion is the lower-leg cut of the hog, sold whole or halved with the leg bone still running through the center. Brands like Smithfield and Hormel cure this section, often smoke it, and ship it labeled as fully cooked, so most of what sits in the meat case has already been through a smokehouse.
What separates the shank from the butt portion (sometimes called the picnic shoulder) is location and fat distribution. The butt portion comes from the upper shoulder and carries more intramuscular marbling, while the shank is leaner with a thick band of fat across the top and a single long bone down the middle. That bone is a flavor asset: it anchors the muscle so the ham stays juicy in the oven, and the marrow seeps a rich base flavor into the drippings as the meat warms.
Reading the Label Before You Heat the Oven
Two phrases on the package decide everything that follows. A label that reads “fully cooked” means the meat has already been brought to a safe temperature by the producer, and your job is simply to reheat it to 140°F. A label that reads “cook before eating” or “partially cooked” means the producer only cured and partially heated the ham, and you must cook it to 145°F per USDA Food Safety and Inspection Service guidance for fresh pork.
HoneyBaked Ham Company and most supermarket spirals ship fully cooked, while a raw shank from a butcher case or farmers market almost always needs full cooking. When in doubt, treat the ham as fully cooked and verify the internal temperature with an instant-read thermometer before pulling it from the oven.
Setting the Right Oven Temperature and Cook Time
325°F (163°C) is the baseline for both reheating a cooked shank and finishing a partially cooked one, because a moderate oven warms the dense muscle evenly without driving off moisture before the center catches up. Going hotter risks a charred crust and a cold center, going lower wastes time and lets the fat render without crisping.
Plan your cook time based on what the label says. A fully cooked shank needs about 15 to 18 minutes per pound at 325°F, so an 8-pound ham will run roughly 2 to 2.5 hours. A fresh, partially cooked, or “cook before eating” shank needs closer to 20 to 25 minutes per pound to reach 145°F internal, which can stretch a 10-pound cut to 4 hours or more. Plan for the longer estimate and check early; an overcooked shank loses moisture faster than an underdone one can recover.
Setup, Foil, and Pan Position
Place the ham cut-side down on a foil-lined roasting pan so the exposed muscle faces the heat and the fat cap shields it. Tent the pan loosely with another sheet of foil so steam can escape; a tight seal traps moisture and prevents the surface from ever drying enough to take on glaze.
Position the rack in the lower third of the oven so the top of the ham sits near the center, where ambient heat is most stable. Rotate the pan once at the halfway mark if your oven runs hot on one side.
Scoring, Glazing, and Seasoning for Flavor
Pat the ham dry with paper towels, then score the fat cap in a shallow diamond pattern about a quarter inch deep. The cuts give the glaze channels to sink into and let a small amount of fat render during baking, which concentrates flavor on the surface.
Stud each diamond with a whole clove, or skip the cloves and press a rub of brown sugar mixed with a teaspoon of dry mustard into the cuts for a sweet-sharp crust that mimics the traditional holiday ham. Spiral vs non-spiral cut matters here: if you’re working with a spiral-cut shank portion, brush the glaze between the slices instead of scoring, since the slices already create channels.
Building and Applying the Glaze
A reliable glaze base starts with brown sugar, maple syrup, honey, or fruit preserves thinned with a splash of apple juice or cider vinegar so it brushes on thin. Keep it thick enough to cling to a spoon, thin enough to drip slowly off a brush.
Brush the glaze on only during the last 20 to 30 minutes of cooking, and apply it in two or three thin coats rather than one heavy pour. Each layer needs about 8 to 10 minutes under the heat to set before the next goes on, so the sugars caramelize in stages instead of burning at the edges. Pull the tented top foil during glazing so the surface is exposed to direct heat.
Brush the final coat of glaze on, then watch the ham closely for the last 10 minutes. Sugars go from caramelized to bitter in a small window, and ovens vary.
Hitting the Safe and Juicy Internal Temperature
An instant-read thermometer is the only reliable way to know when a shank portion ham is ready. For a fully cooked shank you’re reheating, pull the ham at 140°F (60°C), measured in the thickest part of the muscle away from the bone. For a fresh, uncured, or partially cooked shank, push to 145°F (63°C) to meet USDA recommendations for pork.
Always check two spots, one near the center and one toward the thinner end, because bone-in cuts cook unevenly and the thermometer can read low if the tip touches the bone. A reading that hovers between 138°F and 142°F across both spots means the ham is ready to come out, since carryover heat during the rest will finish a 3°F to 5°F rise.
Resting Before You Slice
Let the ham rest uncovered on a cutting board for 10 to 15 minutes once it leaves the oven. The rest lets the muscle fibers relax and reabsorb the juices that pushed toward the center during baking, so a sliced ham holds its moisture on the plate instead of bleeding onto the board.
Loosely tent with foil only if your kitchen is cold or drafty. A tight tent during the rest traps steam and softens any caramelized glaze you worked to build.
Carving and Serving Without Losing the Juices
Set the rested ham flat side down on the board with the bone running parallel to your knife. Slice along the bone from one end to the other to release the main muscle in one piece, then turn that piece flat and cut across the grain into half-inch slices. Cutting across the grain shortens the muscle fibers so each bite feels tender rather than chewy.
Pour the pan drippings through a fine strainer into a small saucepan and simmer them for a few minutes with a splash of stock or apple juice for a quick pan sauce. Spoon the sauce over the slices as you plate, or pass it alongside so each person can add their own.
Putting the Bone to Work
The shank bone carries enough meat and marrow to anchor another meal. Drop it into a pot with split peas, onions, and a bay leaf for a classic split pea soup, or simmer it with white beans, garlic, and herbs for a rustic broth. A single shank bone can flavor 2 to 3 quarts of stock, so refrigerate it within two hours of carving and use it within four days, or freeze it for up to three months.
Common Mistakes and Quick Fixes for Shank Ham
Even experienced cooks dry out a shank portion ham when one of four things goes wrong. The fix for each is straightforward once you spot it, and a little attention during the last 30 minutes of baking saves the entire meal.
- Guessing by time alone: Skip the guesswork and check the internal temperature with an instant-read thermometer. A shank that looks done on the outside can still be 15°F under target at the center, and pulling it at 140°F instead of 155°F keeps the meat juicy.
- Glazing too early: Sugars scorch long before the ham warms through, so hold the glaze until the last 20 to 30 minutes. If the crust already burned, scrape off the bitter top layer, brush on a fresh coat of glaze, and tent the ham loosely with foil while it finishes.
- Slicing straight from the oven: Cutting too soon lets the juices flood the board. Wait the full 10 to 15 minutes of rest, and the slices will hold their moisture instead of weeping.
- Cooking tightly covered the entire time: A sealed foil tent traps steam and prevents any surface browning. Loosen the foil for the final third of cooking so the heat can dry the surface enough for the glaze to set and the fat to crisp.
Cooking Times at a Glance
| Ham Type | Oven Temperature | Time Per Pound | Pull at Internal Temp |
|---|---|---|---|
| Fully cooked shank (reheating) | 325°F | 15 to 18 minutes | 140°F |
| Partially cooked / “cook before eating” | 325°F | 20 to 25 minutes | 145°F |
| Spiral-cut (reheating) | 325°F | 10 to 12 minutes | 140°F |
| Fresh, uncured shank | 325°F | 20 to 25 minutes | 145°F |
Bottom Line
Heat the oven to 325°F, give a fully cooked shank portion ham about 15 to 18 minutes per pound, score the fat, glaze only in the final stretch, and pull it at 140°F before a 10 to 15 minute rest. Treat the bone as a bonus ingredient, and the leftovers will stretch well beyond the first meal.
FAQ
What is a shank portion ham and how is it different from the butt portion?
The shank portion comes from the lower leg of the hog, is sold fully cooked by most producers, and is recognizable by its single long center bone and thick top fat cap. The butt portion comes from the upper shoulder, carries more intramuscular marbling, and usually arrives as a rounder, fattier roast. Both come from the same primal leg, but the shank is leaner and the butt is richer.
Do I need to cook a shank portion ham if it says fully cooked on the label?
No full cook is needed; you only reheat it. Bring a fully cooked shank to 140°F internal in a 325°F oven, which usually takes 15 to 18 minutes per pound. The producer has already taken the meat to a safe temperature, so your goal is warmth without drying.
How long do you cook a shank portion ham per pound?
Plan about 15 to 18 minutes per pound at 325°F for a fully cooked shank that’s only being reheated. For a fresh or partially cooked shank labeled “cook before eating,” allow closer to 20 to 25 minutes per pound to reach a safe 145°F internal temperature.
What temperature and how long do you cook a shank portion ham per pound?
Set the oven to 325°F for both reheating and full cooking. A fully cooked shank runs 15 to 18 minutes per pound to 140°F; a fresh or partially cooked shank runs 20 to 25 minutes per pound to 145°F. Check the internal temperature in the thickest part of the muscle, away from the bone, before you pull it.
Should I glaze a shank portion ham and when should the glaze be applied?
Glazing is optional but adds caramelized flavor and a glossy finish. Apply the glaze only during the final 20 to 30 minutes of cooking in two or three thin coats, and pull the top foil so the surface can brown. Glazing earlier scorches the sugars before the ham warms through.
How do you score a shank portion ham before baking?
Pat the ham dry, then cut shallow diagonal lines across the fat cap about a quarter inch deep in a diamond pattern. The cuts give the glaze channels to sink into and let a small amount of fat render during baking. For a spiral-cut shank, skip scoring and brush glaze between the slices.
