A Step-by-Step Guide to Spatchcocking a Chicken
Step 1: Set a cutting board inside a rimmed baking sheet (it will catch any liquid). Remove the neck and giblets and pat the chicken very dry with paper towels.
Step 2: Using kitchen sheers (we love Joyce Chen's scissors), cut along one side of the backbone, then cut the other side.
Step 3: Flip the chicken over so the inside is facing up and — using a heavy kitchen knife — notch each side of the breast bone (this will help flatten it and make it easy to remove later when carving).
Step 4: Turn the chicken back over and holding the chicken by each breast, pull the breasts up and with your thumbs push the breast bone downward, which will help flatten it.
Step 5: Using the ball of your hand, push on the breast bone to flatten out the chicken.
Step 6: Fold and tuck the wing tips behind the breasts. This will prevent them from burning while roasting.
