A spatchcock turkey cooks much faster than a whole, unbutterflied bird—typically about 4–6 minutes per pound at a relatively high oven temperature, but you should always go by internal temperature, not the clock.

Quick Scoop

  • A common guideline is about 6 minutes per pound for a spatchcock turkey in a hot oven, depending on your exact temperature and oven.
  • Many modern recipes roast at 425°F / 218°C and estimate 4–6 minutes per pound.
  • That means, roughly:
    • 10 lb turkey: 40–60 minutes
* 15 lb turkey: 60–90 minutes

* 20 lb turkey: 80–120 minutes

The Real Doneness Test

  • Time is only a rough guide; the turkey is done when:
    • Breast is about 160°F / 71°C
    • Thigh is about 165°F / 73°C
      measured in the thickest parts with an instant‑read thermometer.
  • Spatchcocking spreads the bird flat, so it roasts more evenly and in about half the time of a traditional whole turkey.

Example Timelines

  • At 425°F in a conventional oven, many home cooks report:
    • Around 1–1.5 hours for birds in the 12–18 lb range.
  • Some guides summarize it simply as “expect 60–90 minutes total” for typical holiday‑sized spatchcock birds, adjusting up or down with size.

Simple Game Plan

  1. Preheat oven to 400–450°F (many recipes favor 425°F).
  1. Estimate 4–6 minutes per pound to know when to start checking.
  1. Start checking temps at the earliest end of the window.
  1. Pull the turkey when breast is about 160°F and thigh about 165°F, then rest 20–30 minutes before carving.
