General tips
Spatchcocking (removing the backbone) is essential for sous vide whole chicken. A round bird does not fit in a bag and cooks unevenly. Flattened, it fits in a large bag and every part cooks at the same rate.
150°–155°F for 3–4 h gives you the juiciest whole chicken possible. The white and dark meat reach the same temperature simultaneously, which oven roasting cannot achieve.
The skin will be pale and soft after the bath. A 15–20 min blast at 475°F or under the broiler is essential to brown and crisp it. Brush with butter and oil before the heat.
Make stock from the removed backbone while the chicken cooks. Simmer with onion, celery, and peppercorns for a bonus quart of broth.
Anti-tip: do not try to crisp the skin in a skillet after sous vide. A whole spatchcocked chicken is too large and unwieldy for a pan. Use the oven or broiler where it can lie flat.
Standard tips
Dry brining for 2–8 h ensures crispy skin when finished
Use an extra-large bag or 2-gallon zip-top bag for whole chickens
Spatchcocking before bagging makes the chicken easier to fit in the bag
Save the bag juices for making gravy
