How Long Does It Take to Smoke a Ham? Four Cooks, Four Timelines

An 11-pound fully cooked bone-in ham needs about 2 hours 45 minutes to 3 hours 20 minutes in a 250°F smoker to reach 140°F, the temperature USDA's Food Safety and Inspection Service sets for reheating a plant-sealed ham. The same ham at 225°F takes 3 hours 20 minutes to 4 hours. A raw fresh ham of that weight takes 6 to 10 hours to reach 145°F. Smoked pulled ham takes 8 to 12 hours. Which number applies to you is printed on the package, and most disagreement about ham timing is people answering different questions with the same figure.

The label already told you which cook you signed up for

FSIS recognizes three states a ham can arrive in, each with its own finish temperature. A fully cooked ham is safe cold out of the wrapper; heat it to 140°F if it was packaged in a USDA-inspected plant, 165°F if it was repackaged anywhere else, which covers deli ham and anything you carved yourself. A cook before eating ham took a cure but no full cook, and has to reach 145°F followed by a three-minute rest. A fresh ham is an uncured raw pork leg with no relationship to the pink thing in the holiday display, and it finishes at that same 145°F.

That 145°F is why old recipes and new ones disagree. USDA lowered whole cuts of pork from 160°F to 145°F with a three-minute rest on May 24, 2011, and both numbers have stayed in print ever since. Fifteen degrees of overshoot is a lot of squeezed-out water for no safety benefit.

The second label line decides how the ham behaves in heat. Under 9 CFR 319.104, the words that follow "Ham" are set by protein fat-free content: Ham at 20.5% PFF or higher with no added water, Ham with Natural Juices at 18.5%, Ham, Water Added at 17.0%, and Ham and Water Product, X% of Weight is Added Ingredients below 17.0%, with that percentage stated on the label.

The qualifier is not decoration: the same regulation sets its minimum type size at three-eighths of an inch, and I spent eleven years on the printing side of that rule. A ham labeled "and water product" at 23% carries most of a quart of brine that it will give back to your foil pan, and it will taste thinner than a 20.5% ham however you cook it.

| What you bought | Pit temp | Pull at | Minutes per pound | 11-pound example | |---|---|---|---|---| | Fully cooked, bone-in, plant-sealed | 250°F | 140°F | 15–18 | 2h45m–3h20m | | Fully cooked, bone-in, plant-sealed | 225°F | 140°F | 18–22 | 3h20m–4h | | Fully cooked, spiral-cut, panned and foiled | 250°F | 140°F | 10–12 | 1h50m–2h15m | | Cook before eating, or fresh ham | 225–275°F | 145°F + 3-min rest | 35–55 | 6–10 hours | | Pulled ham (any cooked ham, different destination) | 250°F, then 300°F | 200–205°F | not usable | 8–12 hours |

Reheating a fully cooked ham: the cook nearly everyone means

FSIS publishes a timetable for this, and every number in it is indexed to a 325°F oven: fully cooked whole bone-in ham at 10 to 14 pounds runs 15 to 18 minutes per pound, half bone-in at 5 to 7 pounds runs 18 to 24, boneless at 6 to 12 pounds runs 10 to 15, and spiral-cut at 7 to 9 pounds runs 10 to 18. Drop the cooker to 250°F and those minutes stop being true. You have shrunk the gap between meat and air by 75 degrees, and heat crosses a smaller gap more slowly.

I learned that from the wrong side. The first ham I put in a smoker, I did the exact thing I had spent eleven years writing instructions to prevent: I used the number off the back of the packet. The sleeve said 15 minutes per pound, I gave a 9-pound shank two and a quarter hours at 250°F, and pulled it on the clock because it looked right. The center read 109°F. Dinner went out an hour and ten minutes late and I finished it in the oven, which is a graceless way to end a smoke. The minutes on a packet are welded to the oven temperature printed beside them. Move one and you have invalidated the other.

For planning at smoker temperatures, budget 15 to 18 minutes per pound at 250°F and 18 to 22 at 225°F for bone-in, and knock about 20% off for boneless. Bone-in runs slower because the leg is thicker through the middle, not because bone conducts differently. A ham going on straight from a 38°F refrigerator runs at the long end of the band. Probe the thickest section, angled away from the bone, cook to 140°F rather than to a clock, and budget an extra hour anyway. A finished ham holds well wrapped in a cooler.

Is 225°F or 250°F better? For a cooked ham, 250°F

Until about 2021 I told people 225°F on the theory that more hours meant more smoke. I stopped, and the reason is chemical. A cured ham is finished meat: its connective tissue was already rendered at the plant, and its pink color is nitrosylmyoglobin, fixed by the sodium nitrite in the cure. The smoke ring you would spend hours chasing on a raw shoulder is already there, all the way through, before you open the bag. Extra time in a 225°F chamber has nothing left to accomplish inside the meat and only gives moisture longer to leave. On an 11-pound ham the difference is roughly 40 minutes of pure loss, so I run 250°F for anything already cooked and save 225°F for the raw leg.

The strongest argument against me is about the outside of the ham, and it is partly right. Smoke compounds condense onto a surface that is cool and damp, so the first stretch of the cook does most of the color and flavor work, and a ham held at 225°F stays in that receptive window longer than one at 250°F. The lower pit gives you a darker, more even mahogany, and I grant that. What I do not grant is that it matters much on a product the plant already smoked, where you are laying a second coat over an existing one. On a spiral-cut ham it is a straight loss, because every exposed slice face is a drying surface and 40 extra minutes shows up as curled, leathery edges.

A raw fresh ham is a 6-to-10-hour project

The comparison trips people because "ham" on a recipe page and "ham" at the meat counter can be two unrelated jobs. A fresh ham is a raw pork leg with no cure and no prior cook, so it travels from refrigerator temperature to 145°F through 10 to 15 pounds of solid muscle. Traeger's guidance puts fresh ham at 225°F to 325°F and 5 to 10 hours; running the low end of that range on a pellet grill, plan 35 to 55 minutes per pound, which lands an 11-pound leg between 6 and 10 hours before the three-minute rest.

Two consequences arrive late. A fresh ham smoked without curing tastes like excellent smoked pork roast and nothing like ham, because ham flavor comes from nitrite and salt, not from the leg; getting it there takes a wet cure for several days, scaled to thickness. A fresh ham also stalls. Somewhere in the 150s the evaporative cooling off the surface balances the heat going in and the temperature sits still for an hour or more, which is why the honest window is four hours wide.

My limit, plainly. I have never cured and smoked a raw pork leg myself. Eleven years of my working life went to product that arrived already cooked, under a thermal process someone else validated; what I know is what happens when it meets a home appliance. For the fresh ham I am handing you USDA's finish temperature and Traeger's window and telling you they are someone else's numbers. What I can vouch for is the reheating side, where I have watched instructions fail in enough kitchens to know which assumption broke.

Pulled ham runs past doneness on purpose

Smoked pulled ham uses the same cooked ham from the same shelf and ignores 140°F entirely. It runs in two stages: smoke uncovered until the ham reaches 165°F, roughly 4 hours at 250°F, then wrap it in a foil pan with 12 to 14 ounces of liquid, raise the cooker to about 300°F, and drive it to 200°F to 205°F. Traeger's pulled ham recipe uses 195°F to 205°F and fork-tender as its pull signal; Meat Church calls tender at over 203°F. Total time runs 8 to 12 hours for a bone-in shank.

The number does not do the work alone. The thermometer should slide in with no resistance anywhere in the muscle; if it does not, the ham goes back covered for another 30 minutes. Rest it at least an hour before pulling, because ham shreds badly hot and gives its liquid back warm.

Covered or uncovered, and where the moisture actually goes

Uncovered for the first 90 minutes, then covered, because the two halves of the cook have different jobs. Smoke deposits on a cool, damp exterior, and by 90 minutes the surface is dry and warm and taking very little more. Everything after that is heat transfer, which runs faster and gentler inside a sealed foil pan than in dry moving air.

USDA agrees for one specific case. FSIS's instruction for reheating a spiral-sliced ham is to cover the entire ham in heavy aluminum foil and heat at 325°F for about 10 minutes per pound, and FSIS adds that spiral-cut hams are safe cold and arguably better that way, since reheating dries the slices and melts the glaze off. If your ham came pre-sliced, the pan and foil go on at the start.

Three things help, in order of effect: pulling at 140°F instead of 155°F, a water pan to keep chamber humidity up and slow surface evaporation, and a cup of cider or stock in the covered pan for the second half. The first dwarfs the other two. A "water added" ham also purges a startling amount of its own brine into that pan, which is the best basting liquid you will get.

How long to rest a smoked ham

Two rest times get confused here. The three-minute rest USDA specifies for 145°F pork is a food-safety instruction: the temperature holds or keeps climbing during those three minutes, which is what makes 145°F equivalent to the old 160°F. It applies to fresh and cook-before-eating hams, not to a reheated cooked one.

The carving rest is longer. Tent the ham loosely with foil for 15 to 30 minutes before slicing. Carryover on a reheated ham is small, usually 2°F to 4°F, because the gradient from surface to center at 250°F is shallow; the rest is for muscle fibers relaxing their grip on liquid. Traeger notes a double-smoked ham can sit at room temperature up to 2 hours before serving, which is the practical answer to a smoke that finishes early.

Glaze goes on at 130°F, not before

Glaze is sugar, and sugar over live heat for three hours turns bitter and black. Brush the first thin coat when the internal temperature reaches about 130°F, which on an 11-pound ham at 250°F is the last 20 to 30 minutes, then re-coat every 10 to 15 minutes until you hit 140°F. Traeger's instruction is the same: glaze during the last half hour or so, at about 130°F.

Thin coats matter more than the recipe. Each layer sets and concentrates before the next arrives, which produces a lacquered finish rather than a wet one that slides onto the grate. For a hard shell, raise the cooker to 325°F for the final 15 minutes rather than glazing earlier. Heavy brown sugar and honey glazes scorch fastest; if the exterior darkens ahead of the center, tent it with foil and keep going.

The leftovers are the fourth cook, and they have their own number

Carved ham is not the same food safety object as the sealed ham you started with. FSIS is explicit: leftover cooked ham and any ham repackaged outside the plant get reheated to 165°F, not 140°F, because unpackaged cooked ham can pick up pathogens after it leaves the plant. The 140°F figure only ever applied to the intact package.

Storage times split the same way, per the FoodSafety.gov Cold Food Storage Chart. A fully cooked vacuum-sealed ham, unopened, keeps 2 weeks or until its use-by date. A cooked, store-wrapped whole ham keeps 1 week. Cooked slices, halves, and spiral-cut ham keep 3 to 5 days. Carved and boxed as leftovers, you are at 3 to 4 days, and the clock starts when it comes off the smoker. Get it into shallow containers within two hours, or one hour above 90°F, since a whole ham on the counter cools far too slowly through the range where bacteria multiply fastest.

FAQ

How long should an 11-pound ham smoke at 250°F?

If it is fully cooked and bone-in, budget 15 to 18 minutes per pound, so 2 hours 45 minutes to 3 hours 20 minutes, and pull it when the thickest part away from the bone reads 140°F. If the same 11 pounds is a raw fresh leg, it needs 6 to 10 hours to reach 145°F instead.

How can I keep a ham moist in a smoker?

Cook to temperature rather than to the clock, because every minute past 140°F is loss with no gain. Run a water pan, leave the ham uncovered for the first 90 minutes to take smoke, then move it to a foil pan with a cup of cider or stock and cover it. Spiral-cut hams need the pan from the start.

Is 225°F or 250°F better for smoked ham?

For a fully cooked ham, 250°F. The collagen was rendered at the plant, so the extra 40 minutes at 225°F buys a little color and costs moisture. Use 225°F for a raw fresh ham, where the slower climb has connective tissue to work on and the cook already runs 6 hours or more.

How long does a pre-cooked ham need in a smoker?

Roughly 15 to 18 minutes per pound at 250°F, or 18 to 22 minutes at 225°F, until the center reads 140°F. USDA sets 140°F for hams sealed in a federally inspected plant and 165°F for any ham repackaged elsewhere, which includes deli ham and your own carved leftovers.

How long does a raw ham take on a pellet grill?

Between 6 and 10 hours for a 10-to-12-pound leg at 225°F to 275°F, finishing at 145°F with a three-minute rest per USDA. Traeger gives a comparable 5-to-10-hour window. A raw ham has no cure, so it will taste like smoked pork roast rather than ham unless you brine it first.

Should a ham be smoked covered or uncovered?

Uncovered for the first 90 minutes, then covered. Smoke sticks to a cool, damp surface, and after about 90 minutes the ham stops taking meaningful color. USDA's own instruction for spiral-cut ham is to cover it entirely in heavy aluminum foil and heat at 325°F for about 10 minutes per pound.
