How Long to Cook a 22lb Turkey: Perfect Timing Guide

Direct Answer: A 22-pound unstuffed turkey requires approximately 4 hours and 45 minutes to 5 hours and 15 minutes when roasted at 325°F. Always verify doneness with a meat thermometer—the thickest part of the breast should reach 165°F and the thigh 175°F for safe consumption.

Planning your holiday feast? Getting the timing right for a 22-pound turkey is crucial for a juicy, flavorful centerpiece that's cooked to perfection. As someone who's prepared hundreds of holiday turkeys in professional kitchens across Europe, I know exactly how to navigate the challenges of cooking a large bird without drying it out or risking undercooking.

Why Turkey Size Matters: The Science Behind Cooking Times

When you're working with a 22-pound turkey, you're dealing with significant thermal mass that requires careful heat management. The USDA Food Safety and Inspection Service confirms that larger turkeys take proportionally longer to cook through because heat must penetrate from the exterior to the center without overcooking the outer portions.

Unlike smaller birds, a 22lb turkey has greater density that affects heat distribution. This is why simply doubling the cooking time of a 10-12lb turkey won't yield accurate results. The relationship between weight and cooking time isn't linear—it's exponential due to the physics of heat transfer in dense proteins.

Turkey Weight Unstuffed Cooking Time Stuffed Cooking Time Resting Time
12-14 lbs 3-3½ hours 3¼-3¾ hours 20-30 minutes
15-18 lbs 3½-4 hours 3¾-4¼ hours 25-35 minutes
18-22 lbs 4-4½ hours 4¼-4¾ hours 30-40 minutes
22-24 lbs 4¼-5 hours 4½-5¼ hours 35-45 minutes

The Step-by-Step Cooking Timeline for Your 22lb Turkey

Preparation Phase (1-2 Hours Before Cooking)

  • Thaw completely: If frozen, allow 5-6 days in the refrigerator (5 pounds per day)
  • Dry brine (optional but recommended): Apply salt mixture 24-48 hours ahead for juicier meat
  • Bring to room temperature: Remove from fridge 1-2 hours before roasting for even cooking
  • Prepare your thermometer: Calibrate your instant-read thermometer before use

Cooking Phase (4½-5¼ Hours)

  1. Preheat oven to 325°F (conventional) or 300°F (convection)
  2. Position turkey breast-side up on rack in roasting pan
  3. Cook uncovered for first 2 hours
  4. After 2 hours, check internal temperature in breast (should be around 110°F)
  5. Loosely tent breast with foil if browning too quickly
  6. Continue roasting, checking temperature every 30 minutes after 3½ hours
  7. Final temperature check: breast 165°F, thigh 175°F

Resting Phase (35-45 Minutes)

This critical step allows juices to redistribute throughout the meat. Never skip resting time—it's what transforms a potentially dry turkey into a moist masterpiece. Tent loosely with foil and place in a warm area while you prepare gravy.

Avoiding Common Pitfalls with Large Turkeys

When cooking a 22-pound turkey, certain mistakes become more costly than with smaller birds. Based on my experience teaching cooking classes across France and the UK, here are the most frequent issues I see:

The Temperature Trap

Many home cooks rely solely on time estimates without verifying internal temperature. The USDA Meat and Poultry Hotline emphasizes that visual cues alone cannot confirm safety. A 22lb turkey might appear done on the outside while still undercooked internally.

Stuffing Complications

If you choose to stuff your turkey, add 15-25 minutes to the total cooking time. More importantly, the stuffing must reach 165°F for food safety. Many professional chefs now recommend cooking stuffing separately to avoid prolonging turkey cooking time, which can dry out the breast meat.

Oven Variability Factors

Your actual cooking time may vary based on:

  • Oven calibration (use an independent oven thermometer)
  • Roasting pan material (dark metal vs. glass)
  • Convection setting usage (reduces time by 25%)
  • Opening the oven door frequency

Special Considerations for Large Bird Cooking

When working with a 22-pound turkey, certain techniques become essential for success:

The Two-Temperature Method

Start at 425°F for 30 minutes to crisp the skin, then reduce to 325°F for the remainder of cooking. This technique, commonly used in French cuisine, creates beautiful browning while ensuring gentle, even cooking through the large bird.

Strategic Foil Tenting

After the first 2 hours, loosely cover just the breast area with foil. This prevents the thinner breast meat from overcooking while the thicker thigh and leg portions continue to reach proper temperature.

Temperature Monitoring Strategy

Insert your thermometer into three critical areas:

  1. The thickest part of the breast (avoiding bone)
  2. The inner thigh (again avoiding bone)
  3. The center of any stuffing (if used)

The National Turkey Federation confirms that temperature readings should be taken in multiple locations because heat distribution varies significantly in larger birds.

When Things Don't Go According to Plan

Even experienced cooks encounter challenges with large turkeys. Here's how to handle common issues:

Turkey Cooking Too Slowly

If after 4 hours your turkey hasn't reached 150°F internally:

  • Verify your oven temperature with a separate thermometer
  • Consider increasing oven temperature by 25°F
  • Ensure turkey isn't sitting in excessive liquid in the pan

Turkey Cooking Too Quickly

If your turkey is browning too fast or approaching target temperature early:

  • Reduce oven temperature by 25°F
  • Add additional foil tenting
  • Place a pan of water on the rack below to create steam

Final Pro Tips for Turkey Success

  • Invest in an oven thermometer: Most built-in oven thermometers are inaccurate by 25°F or more
  • Use a probe thermometer: Allows continuous monitoring without opening the oven
  • Calculate backwards: Determine when to start based on serving time, not just clock time
  • Account for carryover cooking: Temperature will rise 5-10°F during resting

Remember that cooking a 22-pound turkey successfully requires patience and attention to detail. The difference between a dry bird and a succulent centerpiece often comes down to those final 30 minutes of cooking and the crucial resting period. By following these guidelines and verifying with a thermometer, you'll serve a turkey that's both safe and spectacular.
