There’s nothing quite like the satisfaction of preparing a delicious and healthy meal using fresh, whole fish. Grouper, with its firm texture and mild flavor, is an excellent choice for a variety of dishes. To make the most of your grouper, it’s essential to know how to properly filet it. In this article, we’ll take you through the step-by-step process of filleting a grouper, providing tips and tricks along the way to ensure you get the best results.

Gather Your Tools

To successfully filet a grouper, you’ll need the following tools:

  • A sharp fillet knife: This specialized knife has a thin, flexible blade, making it perfect for the delicate task of filleting fish.
  • A cutting board: Choose one that’s easy to clean and non-slip, ideally with grooves to catch juices.
  • A pair of kitchen shears: These will come in handy for trimming fins and cutting through bones.
  • A clean towel or paper towels: You’ll need these for patting the fish dry and wiping down your work area.
  • A container or plate: This is for placing your fillets as you work.

Prepare Your Grouper

Before you begin filleting, it’s essential to clean and gut your grouper. If you’ve purchased your fish whole, follow these steps:

  • Rinse the fish under cold water, removing any debris or slime.
  • Use your kitchen shears to trim off the dorsal and anal fins.
  • Make a shallow incision from the anus towards the head along the belly, being careful not to puncture the internal organs.
  • Remove the internal organs by gently pulling them out with your fingers or a spoon. Rinse the cavity thoroughly under cold water.
  • Pat the fish dry with a clean towel or paper towels.

Make the First Cut

Place the grouper on your cutting board, with the dorsal fin facing away from you. With your non-dominant hand, grip the fish firmly by the tail. Using your fillet knife, make a diagonal cut just behind the pectoral fin, angling the knife towards the head. Cut down until you feel the backbone.

Follow the Backbone

Starting from the initial cut, angle your knife slightly towards the tail and begin slicing along the backbone. Use long, smooth strokes, keeping the blade as close to the backbone as possible to avoid wasting meat. As you slice, use your other hand to gently lift the fillet away from the bones. Continue cutting until you reach the tail, then remove the fillet entirely.

Remove the Rib Bones

Now that you have your first fillet, it’s time to remove the rib bones. Place the fillet skin-side down on the cutting board, with the rib bones facing away from you. Position your knife at the edge of the rib bones, angling it slightly towards the bones. Carefully slice along the bones, using a gentle sawing motion to separate the meat from the bones. Once you’ve detached the rib bones, set the fillet aside on your plate or container.

Repeat on the Other Side

Turn the grouper over so the opposite side is facing up, and repeat steps 3-5 to remove the second fillet.

Remove the Skin (Optional)

Some people prefer to remove the skin from their grouper fillets. If you’d like to do this, follow these steps:

  1. Place the fillet skin-side down on the cutting board, with the tail end facing towards you.
  2. Holding the tail end with your non-dominant hand, slide the fillet knife between the skin and the meat, angling the blade slightly towards the skin.
  3. Apply gentle pressure as you move the knife along the fillet, keeping it parallel to the cutting board. Use a sawing motion to separate the skin from the meat, being careful not to cut through the skin.
  4. As you work, pull the skin away from the meat with your non-dominant hand, ensuring the blade remains in contact with the skin at all times.
  5. Once you’ve removed the skin, check the fillet for any remaining scales or small bones and remove them as needed.

Check for Pin Bones

Grouper fillets may still have a few pin bones running along the centerline. To remove these, run your fingers along the fillet, feeling for any small, thin bones. If you find any, use a pair of needle-nose pliers or tweezers to gently pull them out, being careful not to tear the flesh.

Trim and Portion Your Fillets

Examine your fillets for any excess fat or connective tissue, and trim these away with your fillet knife. You can now portion your fillets into smaller pieces for cooking, if desired. When cutting your fillets into portions, try to keep the pieces relatively uniform in size to ensure even cooking.

Store or Cook Your Grouper Fillets

If you’re not planning to cook your grouper fillets immediately, store them in the refrigerator, wrapped in plastic wrap or placed in an airtight container. For best results, use the fillets within two days.

If you’re ready to cook, grouper fillets can be prepared in a variety of ways, including grilling, pan-searing, baking, or broiling. The mild flavor of grouper pairs well with a wide range of seasonings and sauces, making it a versatile choice for any seafood lover.


Filleting a grouper may seem intimidating at first, but with practice and the right tools, you’ll soon become a pro. By following these step-by-step instructions and tips, you’ll be able to prepare perfectly filleted grouper for your next delicious and healthy meal. Happy cooking!
