How Long to Cook a 15‑Pound Turkey: The Complete Timing Guide

Answer First: 15‑Pound Turkey Cooking Time

For a 15‑pound turkey, the standard rule is 13 minutes per pound at 325°F (163°C) if the bird is unstuffed. That totals about 3 hours and 15 minutes. If you choose to stuff the turkey, add 15 minutes per pound, bringing the total to roughly 4 hours and 15 minutes.

Understanding the Basics

Why 325°F?

325°F provides a balance between safe internal temperatures and even cooking, preventing a dry exterior while ensuring the center reaches 165°F.

Unstuffed vs. Stuffed

Storing stuffing inside the cavity delays heat penetration. That's why you add extra time—15 minutes per pound—to guarantee the stuffing also hits 165°F.

Step‑by‑Step Timing Breakdown

• Preheat oven to 325°F.
• Place turkey breast side up on a rack.
• Cook 13 min/lb (unstuffed) or 13 min/lb + 15 min/lb (stuffed).
• Check internal temp at the thickest part of the thigh.
• Rest 20–30 min before carving.

Key Safety Checks

Internal Temperature

The USDA recommends 165°F (74°C) in the thigh, breast, and stuffing.

Use a Meat Thermometer

Insert the probe into the thickest part of the thigh, avoiding bone, to read the true core temperature.

Practical Tips for a Juicy Result

• Brine or salt‑rub the turkey 12–24 hours before cooking.
• Let the bird come to room temperature (~30 min) before roasting.
• Cover with foil if the skin browns too quickly.
• Rest the turkey uncovered so the skin stays crisp.

Common Mistakes to Avoid

• Over‑baking: leads to dry meat.
• Under‑baking: poses food‑borne illness risk.
• Relying solely on weight: ignore internal temperature.
