How Long to Smoke a Turkey (By Size and Pit Temperature)

Turkey timing is a size question first and a pit temperature question second. Get those two right and the rest is arithmetic you can work backward from dinner.

The short answer, by bird size

These are steady-pit estimates for an unstuffed bird on a smoker held at 300°F. Plan the long end of the range and treat anything faster as a bonus rather than as the plan.

Cook time is pit time only. A schedule built around a fixed dinner is longer, because it starts at fire-up and ends at carving: the Whole Turkey Command Pack plans 6 hours from fire-up to carving for a 12 to 16 pound bird on a 300°F fire, which is this table plus the rest and the hold.

The per pound version

At 300°F a whole turkey cooks at roughly 20 minutes per pound, which is about three pounds of bird per hour. The rule is a useful sanity check from 12 to 18 pounds. Past that it drifts, because a bigger bird spreads the gap between the breast and the thigh more than it adds total time. A 22 pound turkey is not seven and a half hours of cooking; it is a seven hour cook with a wider window to watch.

What pit temperature does to the clock

Turkey smokes hotter than brisket or pork butt. The 275 to 325°F range exists so the skin renders and colors in the time the meat needs, and every step down that range buys smoke flavor with hours. Flattening the bird changes that arithmetic: a spatchcocked turkey runs at 325 to 350°F and finishes in about two hours, because every part of it is the same thickness.

Plan it backward from dinner

Timing a turkey is subtraction rather than guesswork. Count backward from the eating time and the start time falls out.

1. Start with the time you want to sit down. Everything else is subtracted from it.
2. Subtract 30 minutes for the rest after the cook, and more if you want a hold window as insurance.
3. Subtract the long end of the cook time from the table above for your bird size.
4. Subtract 30 to 45 minutes to light the fire and bring the pit to temperature, longer on a cold or windy morning.
5. What is left is your start time. If it lands earlier than you want to get up, run 325°F or buy a smaller bird. Do not shorten the cook instead.

The smoking time calculator turns weight and pit temperature into a start time, and the cookout planner builds the rest of the meal around it.

Thaw time is the step that breaks the plan

A frozen bird is the most common reason a turkey plan fails, and it is decided three or four days before the cook. The USDA thaw rule is 24 hours per 4 to 5 pounds in the refrigerator, so a 16 pound turkey needs three to four days of fridge time, not an afternoon in the sink. A cold-water thaw is faster and needs the water changed every 30 minutes. A counter thaw is not a method. The thawing guide works that schedule out by bird size, and the quantity guide settles how big the bird should be in the first place.

The finish line is temperature, not the clock

Pull the bird when the breast reads 165°F and the thigh reads at least 175°F. Those are two different muscles finishing on their own schedules, which is why the clock gets you to the pit on time and the probe decides when the bird comes off. The smoked turkey temperature guide covers both targets and where to place the probes.

Cooking only a breast removes the second number entirely. The smoked turkey breast temperature guide covers that cook on its own.

When the bird finishes early

A turkey that comes off an hour early means the plan worked. Hold it above 140°F, carve it late, and dinner does not move. The hold guide for a turkey that finished early has the cooler and low-oven options, plus the two-hour safety window.
