How Long to Cook a 13-Pound Spatchcock Turkey

Cooking time can vary for a fully thawed spatchcock turkey, so start checking before the estimated finish. Start checking before the estimated finish, because the meat thermometer, not the clock, determines when to take it out. Use this schedule to plan your oven roast, then follow the preparation and doneness checks below.

Stage	Time to Allow	What It Means
Oven roasting	About 1½–2 hours	An estimate for a fully thawed, flattened bird
First temperature check	After 1 hour of roasting	Start checking before the expected finish
Resting before carving	20 minutes	Add this to the cooking time when planning dinner

Why a Spatchcock Turkey Cooks Faster

Spatchcocking means removing the turkey’s backbone and pressing the bird flat. That reduces its overall thickness and exposes the legs and breast more evenly to oven heat. It also leaves more skin facing upward, where it can brown.

A minutes-per-pound rule cannot account for how flat the turkey lies.

Two turkeys of the same weight can finish at different times if one is spread out and the other remains arched through the breast. Oven accuracy, pan shape, and crowding the oven with side dishes also affect the cooking time.

That is why a traditional whole-turkey timetable is a poor fit for a spatchcocked bird. Use the estimated window to organize dinner, but check the actual meat temperature early.

How to Roast a 13-Pound Spatchcock Turkey

Have sturdy poultry shears, a stable cutting board, paper towels, seasoning, a roasting pan with a rack, and a meat thermometer ready. An instant-read digital thermometer is especially useful for checking several locations.

Step 1: Thaw the Turkey and Plan Ahead

Set up the refrigerator before thawing. Keep it at 40°F or lower. Place the wrapped turkey on a rimmed tray on a low shelf so leaking juices cannot drip onto other food.
Allow enough thawing time. Plan on 3 to 4 days for a frozen 13-pound turkey, which falls within the 12-to-16-pound thawing category in Honeysuckle White’s guidance.
Check that it is completely thawed. The cavity should be free of ice, and the legs should move readily. If the center is still frozen, continue refrigerator thawing rather than forcing the bird flat.
Limit storage after thawing. Cook a refrigerator-thawed turkey within 2 days, consistent with Honeysuckle White’s turkey FAQs.

Refrigerator thawing is not a cooking-day task. Starting early matters, but so does avoiding a long delay after the bird has completely thawed.

Step 2: Remove the Backbone and Flatten the Turkey

Remove the packaging, neck, and giblets. Pat the turkey dry with paper towels; do not rinse raw poultry, which can splash bacteria around the sink.
Place the turkey breast-side down on a stable cutting board. Using sturdy poultry shears, cut along one side of the backbone, then the other, and remove it.
Turn the bird breast-side up. Press firmly over the breastbone until it cracks and the turkey lies flat.
Spread the legs outward and tuck the wing tips beneath the bird so they are less exposed to direct heat.
Wash your hands and clean and sanitize the tools and surfaces that contacted raw turkey.

If the backbone is too difficult to cut, have a butcher spatchcock the turkey rather than forcing an unsuitable knife through the bones.

Step 3: Preheat, Season, and Arrange the Pan

Preheat a conventional oven to 425°F. Avoid mixing oven settings from different roasting recipes.
Season the turkey on both sides. Oil or softened butter can help distribute seasoning over the skin. Use less added salt if the turkey is already brined, injected, or labeled as enhanced.
Set the turkey breast-side up on a rack inside a rimmed roasting pan. The pan must hold the flattened bird without the legs hanging over its edges.
Position the oven rack so the turkey has clearance above it and is not close to an exposed heating element. Leave space around the pan for air to circulate.

Keep the bird spread flat rather than squeezing it into a narrow pan. Packing vegetables or stuffing tightly underneath can also interfere with airflow and change the cooking conditions.

Step 4: Roast and Begin Checking Early

For conservative dinner planning, useful neighboring-size benchmarks are 1 hour and 45 minutes for a 12-pound bird and 2 hours for a 14-pound bird. Those are planning benchmarks, not a guarantee that a turkey between those weights will finish at an exact interpolated time.

Put the turkey in the preheated oven and roast uncovered. Note the starting time.
Begin temperature checks after 1 hour with an instant-read digital thermometer. Check the breast and legs on both sides rather than assuming the entire bird is heating identically.
Keep roasting if the meat has not reached the safe endpoint. As it gets closer, check more frequently so you can remove it promptly.
Avoid repeatedly opening the oven to inspect or baste the bird. Each opening lets heat escape, and basting is not a substitute for measuring doneness.

A leave-in probe can help you watch the trend, but it measures only the spot where its tip sits. Confirm the result in other locations with an instant-read thermometer.

Step 5: Verify Doneness, Rest, and Carve

Before removing the turkey, verify a minimum internal temperature of 165°F in the thickest part of the breast and the innermost parts of the thigh and wing. Check both sides, keeping the thermometer tip away from bone.
If any location is below the target, continue roasting and check again. For this straightforward method, reach the safe temperature during cooking rather than relying on an assumed rise during resting.
Transfer the turkey to a carving board with a juice groove and rest it for 20 minutes. If you use foil, tent it loosely rather than wrapping it tightly and trapping steam against the skin.
Remove the legs and separate the thighs from the drumsticks. Remove the breast meat from the breastbone, then slice it across the grain.

Resting belongs in your dinner schedule. Do not plan to take the turkey out of the oven at the exact moment you want to start serving it.

Pellet-Grill Smoking Takes Longer

Low-temperature smoking follows a different schedule from hot oven roasting. Do not use the oven estimate to decide when a smoked turkey should be ready.

Start with a fully thawed, already-spatchcocked, seasoned turkey. For Traeger pellet grills, its low-temperature smoking method begins by preheating the grill to 225°F.

Place the bird breast-side up. On a Traeger pellet grill, the initial smoking phase commonly takes about 3–4 hours, depending on the turkey’s size, until the internal meat thermometer reads 160°F in the breast. That reading is a checkpoint for changing the heat, not the serving endpoint.

For Traeger’s crisping finish, raise the pellet grill to 375°F and cook for another 20–30 minutes, finishing only when the turkey reaches 165°F in the breast and the innermost thigh and wing. Use the internal thermometer to judge progress and an instant-read thermometer to verify other locations; the estimated duration does not override a low reading.

Rest the turkey for 20 minutes before carving and serving. This method needs a substantially larger dinner-time allowance than oven roasting, especially when the grill is slow to recover heat.

When the Usual Oven Timing Does Not Fit

When browning, thermometer readings, bird type, or cooker conditions differ, rely on the lowest valid meat reading rather than the oven schedule.

The Skin Browns Before the Meat Is Ready

Dark skin does not prove that the center is cooked. A high rack position, an oven hot spot, or a sugary coating can brown the outside ahead of the meat.

Loosely shield the darkening areas with aluminum foil while the turkey continues roasting. If one side is browning much faster, rotate the pan carefully. Keep measuring the cooler meat rather than repeatedly judging the surface.

Do not tightly wrap the whole bird merely because one section is getting dark. Shielding the affected area protects it while leaving the rest of the skin exposed.

Breast and Leg Readings Differ

Different readings are normal, but first check your thermometer placement. A probe against bone or pushed through a thin section can give a misleading result.

Move the tip into the center of the meat and check another nearby spot. Check both halves of the bird, too: an oven hot spot can make one side cook faster than the other.

Treat the lowest valid reading as the reason to keep cooking. Do not average a low reading with a high one.

You Are Cooking Wild Turkey or Using a Trash Can Cooker

Use the turkey’s dressed, ready-to-cook weight, not its field weight, when estimating roasting time. Wild and domestic birds can differ in breast thickness and body shape, so equal weights do not guarantee equal cooking times.

This oven schedule is not a calibrated timetable for a trash can turkey cooker. Fuel, heat distribution, and the cooker’s arrangement create different conditions; do not assume its cooking time will match a controlled oven.

Confirm Doneness and Keep Leftovers Safe

Turkey can remain pink after reaching 165°F, including when it has been smoked. Pink meat alone is not a reason to keep roasting a bird that has passed all the required temperature checks.

The reverse is equally important: white meat, browned skin, and clear-looking juices do not establish safety. The thermometer reading is the deciding evidence.

Once the turkey has rested, carve with clean utensils on a clean board. Keep cooked meat away from the platter, tools, and juices that held the raw bird.

Refrigerate leftovers within 2 hours of cooking, or within 1 hour if the surrounding temperature is above 90°F. Divide leftover meat into shallow containers rather than leaving a large pile to cool slowly.

Carve what you plan to serve, then get the remaining meat portioned and into the refrigerator promptly.

Frequently Asked Questions

How Long Should I Cook a 13.5-Pound Spatchcock Turkey?

Allow about 1½–2 hours at 425°F for a fully thawed, 13.5-pound spatchcock turkey. The additional half-pound is not a reason to add a fixed number of minutes; thickness, flattening, and oven performance matter more than that small weight difference. Begin checking after 1 hour and let measured doneness determine the finish.

Should I Roast a 13-Pound Spatchcock Turkey at 300°F?

For home-oven roasting, choose at least 325°F rather than 300°F, following the USDA’s recommended minimum oven temperature for roasting turkey. Do not transfer a low-temperature pellet-grill schedule to the oven: it is a different cooking method, not an interchangeable timetable.

How Many People Will a 13-Pound Turkey Feed?

A 13-pound turkey generally feeds about 8–10 people with side dishes. Plan toward the lower end for generous portions or leftovers. Spatchcocking changes the bird’s shape and cooking time, not the amount of edible meat it provides.

How do you spatchcock a 13- or 20-pound turkey?

You can use the same spatchcocking process for either size. Set the turkey breast-side down, cut out the backbone with poultry shears, then turn it breast-side up and press on the breastbone until the bird lies flat.
