Copper River King Salmon: Fillet, Trim & Grill on Cedar Plank Like a Pro
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:
- How to fillet and trim a whole Copper River King Salmon
- 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:
- Lay the salmon flat with the belly facing you.
- Make a clean cut behind the gill plate, angling toward the head and stopping at the spine.
- Turn the knife horizontally and glide it along the backbone toward the tail.
- 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:
- Preheat your grill to medium (375°F / 190°C)
- Place the soaked cedar plank directly on the grill grates
- Mix oil, lemon zest, lemon juice, and honey in a small bowl
- Brush the marinade over the salmon
- Place the salmon skin-side down on the cedar plank
- Cover grill and cook for 12–15 minutes
- Check for doneness — fish should flake easily and reach 130–135°F inside
- 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.

3. What’s the difference between King, Coho, and Chum salmon?

4. Can I eat the belly or trim?
Yes! The belly is actually the richest part. Use it in pan-sears or sushi. You can even buy pre-cut salmon belly strips ready to cook.
5. Do I need to remove the skin before grilling?
Nope. In fact, leaving the skin on protects the fish and helps it release from the grill. Plus — crispy skin is delicious.
