Butterfly

Slice nearly through and open flat for even, faster cooking

Butterflying slices a thick cut of meat, fish, or shrimp almost all the way through and opens it like a book, so it cooks faster and more evenly or holds a stuffing. It's ideal for chicken breasts and pork loin. Keep the knife level and steady so both halves end up the same thickness.

Butterflying slices a thick piece of meat, fish, or shrimp almost all the way through and opens it out like a book, halving its thickness. The point is even, faster cooking — a thick chicken breast that would dry out at the edges before the center cooks becomes a thin, quick-cooking piece — or creating a flat surface to hold a stuffing before rolling. The skill is keeping the knife level so both halves end up the same thickness, leaving a hinge of meat so it opens but doesn't separate. It's a simple, high-value cut for weeknight proteins.

Types & varieties

Butterflied chicken breast

Sliced horizontally and opened for fast, even cooking or to flatten for stuffing.

Butterflied shrimp

Cut down the back and opened so it curls attractively and cooks fast.

Butterflied pork loin

Opened flat to spread with a filling, then rolled and tied.

Butterflied leg of lamb

Boned and opened flat for even grilling or roasting.

How to do it

  1. 1

    Steady the meat

    Place the meat flat on the board with your guiding hand resting on top to hold it steady.

  2. 2

    Find the middle

    Aim to slice through the thickest part horizontally, halfway between top and bottom.

  3. 3

    Slice nearly through

    Hold the knife level and cut horizontally toward the far side, stopping just before you cut all the way through.

  4. 4

    Leave a hinge

    Keep a thin connected edge so the two halves stay joined like a book's spine.

  5. 5

    Open it flat

    Unfold the meat at the hinge so it lies open and even.

  6. 6

    Even it out

    Trim or gently pound any thick spots so the whole piece is a uniform thickness.

Why butterfly

Thickness is the enemy of even cooking: by the time the center of a thick breast reaches a safe temperature, the outer layers can be dry and overcooked. Butterflying roughly halves the thickness, so the whole piece cooks quickly and evenly with no dry edges. It also creates a broad, flat surface — perfect for spreading a stuffing and rolling into a roulade, or for fast searing and grilling.

Safety

Cutting horizontally toward your hand calls for care.

  • Keep your guiding hand flat on top of the meat, fingers up and clear of the blade's level path.
  • Use a sharp knife so it tracks cleanly rather than slipping.
  • Cut on a stable, non-slip board.
  • Wash hands, board, and knife well after handling raw poultry.

Tips & pitfalls

  • Keep the knife perfectly level for two even halves.
  • A light pound after butterflying evens out any thick spots.
  • Leave a hinge unless you want two fully separate cutlets.
  • Butterflying is the first step to a stuffed, rolled roulade.
  • Chill the meat slightly for a firmer, cleaner cut.
