How to Filet a Whole Fish
Turning a whole fish into clean, ready-to-cook filets is a skill that saves money and ensures you get the freshest meat possible. You do not need a specialized kit, just a blade that is thin enough to flex against the bone structure.
Sharpness is your safety
A dull knife requires more force, which increases the chance of slipping. Ensure your blade is honed before starting so it glides through the connective tissue rather than dragging.
- Flexible filleting knife
- Large cutting board
- Kitchen tweezers
- Damp paper towels
What goes in.
- 1 wholefresh fish (snapper, trout, or sea bass)
Maintain blade contact
Keep the spine of the knife pressed against the fish's backbone throughout the entire length of the cut. This creates a natural guide that prevents you from cutting into the filet.
The method.
Remove the head and fins
Place the fish on the board with the head to your left. Cut diagonally behind the gill cover, stopping when you hit the backbone, then turn the knife flat and slice toward the tail to remove the head and pectoral fin.
Make the primary incision
Insert the tip of the knife at the top of the head-cut. Run the knife along the top of the dorsal fin, pressing deep enough to feel the backbone, and move in long, steady strokes toward the tail.
Free the filet
Once the top incision is made, use the knife to gently lift the meat while pushing it away from the spine. Use short, gliding motions to separate the meat from the rib bones until the filet is completely removed.
Remove pin bones
Run your fingers lightly against the grain of the meat to locate the pin bones along the midline. Pull each bone out with tweezers, moving in the direction the bone is pointing to avoid tearing the flesh.
Trim the belly
Use your knife to shave off the thin, opaque layer of fat and cartilage along the bottom edge of the filet. The meat should be uniform and clean once finished.
Other turns to take.
Skin-on Filets
Stop the knife just before it cuts through the skin at the tail. Lay the filet skin-side down, insert the knife between the skin and the meat, and slide it toward the tail to remove the skin cleanly.
When it doesn't go to plan.
Keep your work surface dry and stable by placing a damp cloth underneath your cutting board.
Do not discard the head and frame; they are foundations for fish stock.
If the fish feels slippery, pat the skin dry with a paper towel before starting.
The ones that keep coming up.
How do I know if the fish is fresh?
The eyes should be clear and bulging, not sunken or cloudy. The gills should be bright red or pink, never grey or brown.
Does it matter which way the fish is facing?
Place the fish so the head is to your left if you are right-handed. This makes the primary cut along the spine move away from your body.
