cooking time turkey calculator

How long does it take to cook a turkey?

Turkey roasting time depends on four big factors: bird weight, whether it is stuffed, oven temperature, and whether the bird is fully thawed. Most recipes are based on a thawed turkey roasted at 325°F. That is why this calculator starts there, then adjusts upward or downward based on your choices.

A useful rule of thumb is:

• Unstuffed turkey: about 13–15 minutes per pound at 325°F
• Stuffed turkey: about 15–17 minutes per pound at 325°F

These are estimates, not guarantees. Always use a thermometer for doneness.

Turkey cooking time chart (thawed, 325°F)

Turkey Weight	Unstuffed Time	Stuffed Time
8–12 lb	2 hr 45 min – 3 hr	3 hr – 3 hr 30 min
12–14 lb	3 hr – 3 hr 45 min	3 hr 30 min – 4 hr
14–18 lb	3 hr 45 min – 4 hr 30 min	4 hr – 4 hr 45 min
18–20 lb	4 hr 15 min – 4 hr 45 min	4 hr 45 min – 5 hr 15 min
20–24 lb	4 hr 30 min – 5 hr 15 min	5 hr – 5 hr 45 min

How this calculator helps you plan

The calculator gives a time range (low and high estimate), not a single number. This is practical for real kitchens where oven calibration, pan depth, altitude, and bird shape all affect timing.

What to do with the range

• Use the high end to decide when to start roasting.
• Use the low end as your first temperature check point.
• Add at least 30 minutes of resting time before carving.

Best practices for a juicy turkey

1) Start with a fully thawed bird

A frozen or partially frozen turkey can cook unevenly. The outside may dry out long before the center reaches a safe internal temperature.

2) Keep oven door openings minimal

Every peek drops oven temperature and can extend cook time. Baste less often than you think you need to.

3) Trust temperature, not color

Golden-brown skin looks great, but it does not prove food safety. Use an instant-read thermometer in the thickest part of breast and thigh, away from bone.

4) Rest before carving

Resting helps juices redistribute. Carving too soon causes moisture loss and drier slices.

Food safety targets

• Breast meat: 165°F minimum
• Thigh meat: 170–175°F for better texture
• Stuffing (if cooked inside bird): 165°F minimum

If any area reads low, keep roasting and check again every 10–15 minutes.

Common turkey timing mistakes

• Starting too late and skipping rest time
• Roasting a partially frozen turkey without adjusting expectations
• Using only a pop-up timer instead of a thermometer
• Assuming all ovens and all birds cook identically

Quick FAQ

Is 325°F or 350°F better for turkey?

325°F is the most common baseline because it is predictable and forgiving. 350°F can work well for smaller birds and slightly shorter cook windows.

Can I cook a turkey from frozen?

Yes, but timing rises substantially and consistency drops. If possible, thaw first for better texture and safer, easier planning.

Should I cover turkey with foil?

Often yes for part of the roast. Foil can prevent over-browning while the interior catches up. Remove it near the end if you want crispier skin.

How early should I start?

Use the calculator’s high-end estimate, then add a 30-minute rest. If in doubt, start earlier: turkey can rest longer, but late dinner is hard to fix.
