From River to Grill: How to Fillet & Cedar Plank Grill Copper River King Salmon

If you’ve never had Copper River King Salmon, you’re in for something extraordinary. Caught in the icy, fast-moving waters of Alaska’s Copper River, this isn’t your average salmon. It’s the crown jewel of wild-caught fish — rich, fatty, bright in color, and tender enough to melt like butter.

In this guide, we’re breaking down two things:

  1. How to fillet and trim a whole Copper River King Salmon

  2. How to grill it on a cedar plank — smoky, juicy, and perfect every time

Whether you’re a seasoned fish lover or just want to try something wild and premium, this step-by-step will have you cooking like a pro.

📍 What Makes Copper River Salmon So Special?

The Copper River in Alaska is cold, fast, and powerful — and the salmon that swim upstream here need a lot of fat to survive the journey.

That’s why Copper River King Salmon (also called Chinook) are known for:

  • High Omega-3 content

  • Unmatched richness and buttery flavor

  • Vibrant red color

  • Firm texture — perfect for grilling

These are limited-run seasonal fish, often available just a few weeks per year, which makes them both prized and rare. When they arrive fresh, you want to handle them right — and that starts with a clean fillet.

🔪 Step-by-Step: Filleting & Trimming a King Salmon

What You’ll Need:

  • Sharp fillet knife

  • Boning knife (optional)

  • Cutting board or fish-cleaning station

  • Clean towel

  • Tweezers or pliers for pin bones

How to Fillet:

  1. Lay the salmon flat with the belly facing you.

  2. Make a clean cut behind the gill plate, angling toward the head and stopping at the spine.

  3. Turn the knife horizontally and glide it along the backbone toward the tail.

  4. Remove the first fillet, then flip and repeat on the other side.

Trimming:

  • Trim off the belly fat (or save it — it’s delicious and available as salmon belly strips ).

  • Remove rib bones with a boning knife.

  • Use tweezers to pull out pin bones along the center line.

  • Pat dry with paper towels.

Now you’ve got two beautiful, clean fillets — ready for the grill.

🔥 Cedar Plank Grilling Recipe: Copper River King

One of the best ways to cook King salmon is on a cedar plank. The wood infuses smoke and prevents overcooking, while the high fat content of Copper River salmon keeps everything juicy and flavorful.

Ingredients:

  • 1 full Copper River King Salmon fillet

  • 1 untreated cedar plank, soaked in water for 1–2 hours

  • 2 tbsp olive oil

  • Zest of 1 lemon

  • Juice of 1 lemon

  • 1 tbsp honey or maple syrup

  • Salt & pepper to taste

  • Fresh dill or parsley (optional)

Instructions:

  1. Preheat your grill to medium (375°F / 190°C)

  2. Place the soaked cedar plank directly on the grill grates

  3. Mix oil, lemon zest, lemon juice, and honey in a small bowl

  4. Brush the marinade over the salmon

  5. Place the salmon skin-side down on the cedar plank

  6. Cover grill and cook for 12–15 minutes

  7. Check for doneness — fish should flake easily and reach 130–135°F inside

  8. Serve with lemon wedges and fresh herbs

🧑🍳 Pro Tip: Try this with other species too — like Coho Salmon Fillets , Chum Salmon , or Silver Salmon for a milder flavor.
