Grilling salmon on a cedar plank infuses the fish with a subtle, smoky wood flavor without sticking to the grates. Learning how to cook salmon on a cedar plank is easier than you think, and it transforms a simple dinner into something special. You get perfectly cooked fish every time, with a rich aroma that fills your backyard.
The plank acts as a barrier, so the salmon steams gently while absorbing that woodsy taste. No more flipping or worrying about the fish falling apart. Just set it and let the grill do the work.
This method works for beginners and seasoned grillers alike. You don’t need fancy equipment—just a plank, some salmon, and a few basic ingredients. Let’s get started.
Why Cook Salmon On A Cedar Plank
Using a cedar plank adds flavor that you just can’t get from direct grilling. The wood smolders slowly, releasing oils that penetrate the fish. It also keeps the salmon moist and tender.
Another big plus is cleanup. The plank catches all the juices and marinade, so your grill grates stay clean. You simply toss the used plank when you’re done.
It’s also a healthier way to cook. You don’t need extra oil or butter to prevent sticking. The natural moisture of the fish does the job.
Benefits Of Plank Grilling
- Adds a smoky, earthy flavor without overpowering the fish
- Prevents the salmon from sticking to the grill
- Keeps the fish moist and flaky
- Easy cleanup—no scrubbing grates
- Works on gas, charcoal, or even in the oven
How To Cook Salmon On A Cedar Plank
Now let’s walk through the exact steps. Follow this guide, and you’ll have perfect plank salmon every time.
Step 1: Soak The Cedar Plank
You must soak the plank before using it. This prevents it from catching fire on the grill. Submerge it in water for at least 1 hour, but 2 hours is better.
For extra flavor, soak the plank in apple juice, white wine, or a mix of water and soy sauce. This adds another layer of taste to the salmon.
Weigh the plank down with a heavy plate or bowl to keep it fully submerged. If parts stick out, they won’t soak properly and could burn.
Step 2: Prepare The Salmon
Start with a fresh or thawed salmon fillet. Skin-on works best because it holds the fish together during cooking. Pat it dry with paper towels.
Season simply. Salt and pepper are enough, but you can add garlic powder, dill, or lemon zest. Brush the flesh with a little olive oil to help the seasoning stick.
Let the salmon sit at room temperature for 15 minutes while the grill heats up. This ensures even cooking.
Step 3: Preheat The Grill
Set your grill to medium heat, around 375-400°F. For gas grills, light all burners and close the lid for 10 minutes. For charcoal, let the coals burn until they’re covered with white ash.
You want indirect heat for this method. If your grill has two zones, turn off one side and place the plank there. This prevents the wood from charring too fast.
Step 4: Place The Plank On The Grill
Remove the plank from the soak and shake off excess water. Place it directly on the grill grates over indirect heat. Close the lid and let it heat for 3-5 minutes.
You’ll hear a gentle sizzle and see a wisp of smoke. That’s normal. If the plank starts flaming, move it to a cooler part of the grill or spray it with a water bottle.
Step 5: Add The Salmon
Lay the salmon fillet skin-side down on the hot plank. Arrange it so there’s space around the edges for smoke to circulate. Close the lid immediately.
Do not flip the fish. The plank cooks it from below, and the grill’s heat cooks from above. Flipping would break the fillet apart.
Step 6: Cook To Temperature
Cook the salmon for 12-18 minutes, depending on thickness. A 1-inch thick fillet usually takes about 15 minutes. Use a meat thermometer to check doneness.
The ideal internal temperature is 125-130°F for medium, or 135-140°F for well-done. Insert the thermometer into the thickest part of the fish.
The salmon should flake easily with a fork when it’s ready. If it resists, give it a few more minutes.
Step 7: Remove And Serve
Use oven mitts to lift the plank off the grill. The wood will be hot. Place it on a heat-safe surface or a baking sheet.
Let the salmon rest for 5 minutes. This allows the juices to redistribute. Serve directly from the plank for a rustic presentation, or slide the fillet onto a plate.
Discard the used plank after one use. It’s too charred to reuse safely.
Tips For Perfect Plank Salmon Every Time
Getting great results is about the details. Here are some pro tips to avoid common mistakes.
Choose The Right Plank
Buy food-grade cedar planks from a store or online. Avoid lumber from hardware stores—it may contain chemicals. Look for planks that are about 1/2 inch thick.
Thinner planks burn faster. Thicker ones last longer and produce more smoke. If you’re new, start with a standard 12×6 inch plank.
Don’t Skip The Soak
Soaking is non-negotiable. A dry plank will catch fire quickly, ruining your salmon. Even a 30-minute soak helps, but an hour is best.
If you forget to soak, wrap the plank in foil before using. This creates a barrier that slows burning, though you lose some smoky flavor.
Control The Heat
Keep the grill temperature steady. If it gets too hot, the plank will char and the salmon will dry out. Use a grill thermometer to monitor.
For gas grills, adjust the burners to maintain medium heat. For charcoal, spread the coals thinly and add more if needed.
Add Smoke Boosters
Want even more smoky flavor? Add a handful of soaked wood chips to the coals or a smoker box. This works great with charcoal grills.
You can also place a few sprigs of fresh herbs like rosemary or thyme on the plank under the salmon. They’ll release aromatic oils as they heat.
Flavor Variations To Try
Once you master the basics, experiment with different seasonings. Here are three easy ideas.
Lemon-Dill Salmon
Mix 2 tablespoons melted butter, juice of half a lemon, and 1 teaspoon dried dill. Brush over the salmon before grilling. Add thin lemon slices on top.
Maple-Mustard Glaze
Combine 3 tablespoons maple syrup, 1 tablespoon Dijon mustard, and a pinch of cayenne. Spread on the salmon during the last 5 minutes of cooking.
Asian-Inspired Salmon
Whisk together 2 tablespoons soy sauce, 1 tablespoon honey, 1 teaspoon grated ginger, and 1 clove minced garlic. Marinate the salmon for 20 minutes before grilling.
Common Mistakes And How To Avoid Them
Even experienced cooks make errors with plank grilling. Here’s what to watch for.
Plank Catches Fire
This happens when the plank is too dry or the grill is too hot. Always soak the plank fully and use indirect heat. Keep a spray bottle of water handy to douse any flames.
Salmon Sticks To The Plank
If the salmon sticks, it’s usually because the plank wasn’t hot enough when you added the fish. Let the plank heat on the grill for 5 minutes first. Also, oil the plank lightly before placing the salmon.
Salmon Is Dry
Overcooking is the main culprit. Use a thermometer and pull the fish off at 130°F. The residual heat will finish cooking it. Also, don’t open the lid too often—it lets out steam.
Plank Splits Or Cracks
Cheap planks or extreme temperature changes cause this. Soak the plank thoroughly and don’t place it directly over high heat. If it cracks, it’s still usable, but smoke may escape unevenly.
Frequently Asked Questions
Can I reuse a cedar plank?
No, planks are single-use. After grilling, they’re charred and may harbor bacteria. Toss it in the compost or trash.
Do I need to flip the salmon on a cedar plank?
No. The plank cooks the bottom, and the grill’s heat cooks the top. Flipping will break the fish and cause it to stick.
Can I cook salmon on a cedar plank in the oven?
Yes. Preheat the oven to 400°F. Place the soaked plank with salmon on a baking sheet. Bake for 15-18 minutes until done.
How long should I soak a cedar plank for salmon?
At least 1 hour. For best results, soak 2-4 hours. Don’t exceed 8 hours, or the wood may become too waterlogged.
What if I don’t have a cedar plank?
You can use other wood planks like alder, maple, or hickory. Or try grilling salmon on a bed of fresh herbs or citrus slices for similar flavor.
