Why Filleting a Flounder Is Unique

Flounder, like other flatfish species, has a distinct anatomy. Its flat body, with eyes on one side, is different from round fish like salmon or trout. This means that flounder has two fillets on the top side and two on the underside.

Chef Gordon Ramsay describes filleting flatfish as "a rewarding skill for any seafood enthusiast." Mastering this technique ensures you get clean, boneless cuts, perfect for grilling, frying, or baking.

Tools You’ll Need to Fillet a Flounder

Before you begin, gather the following tools to ensure a seamless process:

• A Sharp Fillet Knife: A flexible, razor-sharp knife is essential for clean cuts.
• Cutting Board: Choose a sturdy, non-slip board to keep the fish stable.
• Kitchen Shears: Useful for trimming fins or bones.
• Paper Towels: To pat the fish dry for a better grip.

Pro Tip: Keep your knife sharp! A dull blade can tear the flesh and reduce the quality of your fillets.

Step-by-Step Guide to Filleting a Flounder

1. Prepare Your Workspace

• Place the cutting board on a stable surface.
• Pat the flounder dry with paper towels to prevent slipping.

2. Identify the Flounder’s Anatomy

• Locate the lateral line, which runs along the middle of the fish. This is your guide for making cuts.
• Note the top (dark side) and underside (white side) of the flounder.

3. Start with the First Fillet

• Place the fish dark side up.
• Make an incision just behind the gills and head, angling the knife slightly to maximize the cut.
• Cut along the lateral line, stopping at the tail.

4. Separate the Fillet

• Starting from the lateral line, slide the knife gently under the flesh, following the rib bones.
• Use smooth, even strokes to separate the fillet from the bone.

5. Repeat on the Dark Side

• Turn the fish over and repeat the process on the other fillet on the dark side.

6. Flip to the Underside

• Turn the fish white side up and repeat the process to remove the two fillets on this side.

7. Trim and Clean

• Inspect each fillet for any remaining bones or skin and trim as needed.
• Rinse the fillets in cold water and pat dry.

Pro Tips for Filleting Flounder

1. Use the Right Knife Technique: Let the knife do the work—avoid using too much pressure, which can tear the flesh.
2. Practice Makes Perfect: The more you practice, the more precise your cuts will become.
3. Chill the Fish Before Filleting: Cold fish are firmer, making it easier to work with.
