🔪 How to Fillet a Whole Halibut: Step-by-Step Breakdown

Pacific Halibut is a flatfish, which means it has four fillets—two on the dark (top) side, two on the white (bottom) side.

Tools You’ll Need:

Sharp, flexible fillet knife
Boning knife
Cutting board (large!)
Clean towel or grip mat

1. Prep the Fish

Rinse the fish and pat it dry. Place it dark side up (the darker top side faces the ocean floor and has more meat).

2. Cut & Remove the Collar

The collar is where the head meets the body—fatty, rich, and perfect for grilling or smoking. Use a sharp knife to cut just behind the gills on both sides and remove the collar in one piece.

🧂 Pro tip: Marinate collars in soy, garlic, and sesame oil, then grill over open flame for smoky, crispy edges.

3. Make a Spine-Center Cut

Run your knife along the spine, from head to tail. Keep it shallow—just enough to expose the top of the backbone.

4. Slice Out the First Fillet (Top Left)

Starting at the spine, angle your knife toward the ribs and work outward. Use long, shallow strokes, scraping against the bones. You’ll feel it when you’re doing it right.

Repeat on the top right side for the second fillet.

5. Flip & Repeat

Now place the fish white side up, and repeat the cuts for the bottom two fillets. You should now have 4 skin-on fillets, plus the head, tail, and center bone.

6. Optional: Remove Skin

You can cook halibut skin-on or skinless. If preferred, place each fillet skin-down and slice the meat off carefully, holding the skin taut.

🐟 Don’t Toss That Backbone! Make Bone Broth Instead

Most people throw away the backbone. That’s a mistake. It's full of flavor, collagen, and trace minerals. When simmered slowly, it becomes a rich base for soup, sauces, or sipping broth.

🍲 Halibut Bone Broth Recipe

Ingredients:

Halibut backbone, collars, or head pieces
1 chopped onion
2 stalks celery
1 carrot
3 cloves garlic
1 bay leaf
10 peppercorns
2 tsp sea salt
10–12 cups water
Optional: piece of ginger or lemon peel

Instructions:

Rinse bones and lightly roast them at 375°F for 20 minutes (optional but adds depth).
Add bones, veggies, and spices to a large stock pot.
Cover with water and bring to a boil. Skim off foam.
Simmer on low for 4–6 hours.
Strain, cool, and store in jars or ice cube trays.

💡 Use it for seafood risotto, chowder base, or a warm sipping broth on cold days.

🍽️ How to Cook Your Fillets

Halibut is versatile. Here are three of the best ways to prepare your fillets:

Pan-seared: Cook in butter or oil, skin-side down, 3–4 mins per side
Grilled: Brush with olive oil, season lightly, grill over medium heat
Baked: 400°F for 10–12 minutes with lemon, herbs, and garlic

Avoid overcooking—halibut is lean and can dry out easily!
