Skinning a fish fillet
Intermediate Butchery and seafood
Skinning a fish fillet is separating the skin from a raw fillet in one piece, keeping all the flesh.

How do you do it?
- Lay the fillet skin side down with the tail end nearest your knife hand. Use a long, flexible fillet knife.
- Cut down through the flesh about 1/2 inch from the tail end, stopping at the skin.
- Grip that tab of skin with salted fingertips or a paper towel. Hold the blade nearly flat, tilted slightly toward the skin.
- Pull the skin back and forth while keeping the blade still, so the skin slides off underneath it.
Why does it work?
Between skin and flesh is a thin layer of fat and connective tissue that parts easily if the blade is pressed onto the skin. Moving the skin rather than the knife keeps the cut steady. Skin left on for cooking crisps nicely, so only skin a fillet when the recipe calls for it.
What are the common mistakes?
- Tilting the blade up into the flesh — you lose the fillet's best part.
- Pushing the knife hard — it cuts through the skin and loses its grip.
- Holding a wet skin tab — your fingers slip toward the blade.
