How Long To Cook An Unstuffed Turkey | Cook Times By Weight

An unstuffed turkey usually roasts 2¾ to 5 hours at 325°F, depending on weight, and it’s done once the center reaches 165°F.

Roasting a turkey gets tense when the bird is in the oven, the side dishes are rolling, and the timer still feels like a guess. That’s why a clear time range matters. You want the meat cooked through, still juicy, and ready when the rest of dinner hits the table.

Here’s the part many recipes blur: turkey cooking time is an estimate, not a finish line. Weight gives you the starting point. Oven temperature, whether the bird is fully thawed, the shape of the roasting pan, and how often the door opens can all stretch the roast. The clock gets you close. The thermometer calls it.

What Sets The Cooking Time

An unstuffed turkey cooks faster than a stuffed one because hot air can move through the cavity. That trims some oven time and makes doneness easier to judge. For a plain roasted bird, the standard chart most home cooks use is built around an oven set to 325°F.

A few details change the pace more than people expect:

• Weight: Bigger birds need more time, but not in a straight minute-by-minute pattern.
• Starting temperature: A turkey that goes into the oven still icy in the center will lag.
• Pan setup: Deep pans and tight foil can slow browning and hold heat differently.
• Door opening: Each peek drops oven heat and stretches the roast.
• Oven accuracy: Home ovens drift more than many cooks think.

That’s why the safest way to plan dinner is to use the chart, then build in extra buffer time for resting and carving. A turkey that finishes early is easy to hold warm for a bit. A turkey that finishes late can throw off the whole meal.

How Long To Cook An Unstuffed Turkey By Weight

FoodSafety.gov’s meat and poultry roasting chart says to roast whole turkey at 325°F or higher. For an unstuffed bird, the published range runs from 1½ to 2¼ hours for a 4-to-6-pound breast up to 4½ to 5 hours for a 20-to-24-pound turkey. The same chart says those times are for unstuffed poultry, with extra time needed if the bird is stuffed.

That chart is a strong baseline, but your best dinner timing comes from pairing it with a probe thermometer. USDA’s turkey roasting advice says the bird is safe at 165°F, checked in the innermost part of the thigh and wing and the thickest part of the breast. If one area lags, the turkey needs more oven time even if the timer says it should be done.

If your turkey is still cold in the center when roasting starts, don’t trust the lower end of any range. A fully thawed bird cooks more evenly, browns better, and gives you a truer match to the chart. A half-frozen turkey can leave you with dry breast meat before the thighs catch up.

Turkey Size	Roast Time At 325°F	What To Watch
4 to 6 lb breast	1½ to 2¼ hours	Small breasts can move from pale to done fast, so start checking early.
6 to 8 lb breast	2¼ to 3¼ hours	The thickest part of the breast is your read point.
8 to 12 lb turkey	2¾ to 3 hours	This size often fits the chart closely in a steady oven.
12 to 14 lb turkey	3 to 3¾ hours	Give yourself room for a longer rest before carving.
14 to 18 lb turkey	3¾ to 4¼ hours	Breast skin may brown early; tent with foil only if needed.
18 to 20 lb turkey	4¼ to 4½ hours	Check both thigh and breast so one section doesn’t run ahead.
20 to 24 lb turkey	4½ to 5 hours	Plan extra oven margin, since large birds expose oven hot spots.

When The Turkey Is Actually Done

The cleanest answer is temperature, not color. Brown skin looks good, but it can show up long before the center of the bird is ready. Juices can run clear and still leave you guessing. A thermometer takes that guesswork off the table.

FoodSafety.gov’s safe minimum temperature chart puts all poultry, including turkey, at 165°F. Check three places:

• The innermost part of the thigh
• The innermost part of the wing
• The thickest part of the breast

If those spots read 165°F, pull the bird. Then let it rest. Resting gives the juices time to settle and makes carving cleaner. You don’t need a marathon wait, but you do want enough time that the meat slices neatly instead of flooding the cutting board.

How Long Should The Turkey Rest

For a whole bird, 20 to 30 minutes is a comfortable range. USDA says 20 minutes is good for carving quality after roasting. That rest window helps the breast stay moist and gives you a calm pocket of time to finish gravy, warm sides, or clear counter space.

Don’t skip the rest because the turkey “looks ready.” Right out of the oven, the meat is still pushing juices around. Carve too soon and the slices can dry out on the platter.

Common Mistakes That Throw Off The Timing

Turkey math gets messy when one small habit keeps adding minutes. These are the usual culprits:

• Starting with a bird that is not fully thawed: The outside cooks while the center drags behind.
• Roasting at a lower oven temperature: The chart is built around 325°F.
• Basting every 20 minutes: Repeated door opening dumps heat.
• Trusting the pop-up timer alone: It’s not as precise as a thermometer read.
• Using a crowded pan: Tight pan walls can slow airflow around the bird.

One more thing trips people up: carryover heat is real, but it’s not a free pass to pull the turkey early. You still want that 165°F reading in the right spots before the bird comes out.

Stage	Best Move	Time Target
Before roasting	Start with a fully thawed turkey	Leave enough lead time before roast day
Early roast	Leave the oven closed	No peeking for the first stretch
Near finish	Begin temperature checks	About 30 to 45 minutes before the low end of the chart
After roasting	Rest before carving	20 to 30 minutes
Serving	Carve after the rest window	Right after 20 to 30 minutes of resting

How To Plan Dinner Backward From Serving Time

If you want dinner on the table at 6 p.m., don’t start with the oven time alone. Work backward from the moment you want to carve. Give the turkey its roast window, then add the rest time, plus a small cushion in case your oven runs cool or the bird takes longer than expected.

Say you have a 14-to-18-pound turkey. The chart range is 3¾ to 4¼ hours at 325°F. Add 20 to 30 minutes for resting. Add another 20 to 30 minutes of cushion. That means a 6 p.m. carving time usually points to a roasting start sometime between 1 p.m. and 1:30 p.m., not 2 p.m.

That extra margin can save dinner. If the turkey finishes early, tent it loosely and let it rest. If it finishes right on time, great. If it drifts late, your meal still has breathing room.

What Most Cooks Want To Know

The broad answer is simple: most unstuffed turkeys roast at 325°F for somewhere between 2¾ and 5 hours, based on size. Smaller birds land near the low end. Large holiday birds land near the high end. The move that keeps dinner on track is checking temperature before panic sets in.

If you want the turkey to taste like you meant it, don’t chase a single magic number. Match the bird’s weight to the chart, trust the thermometer over the color of the skin, and leave time for rest before carving. That gives you slices that stay juicy and a serving plan that doesn’t fall apart at the last minute.
