Ingredients for Grilled Cedar Plank Salmon

  • Salmon: Boneless salmon fillet with skin on or off that fits your cedar plank. You can use any wild salmon like sockeye salmon, coho salmon or spring salmon. Farmed salmon or Atlantic salmon works as well.
  • Thai sweet chili sauce: I use my homemade Thai sweet chili sauce or you can also use store-bought one. I like Thai kitchen brand.

Recipe Tip

Wild or farmed salmon? There are differences in health benefits between wild and farmed types of salmon. I recommend to buy wild salmon, if you can afford it. The best salmon to grill on a cedar plank is king salmon (chinook salmon or spring salmon) or coho salmon. I have tried this recipe with sockeye salmon and it turns out a little bit dry, so be sure to cook it for less time. Atlantic or farmed salmon has higher percentage of fat and comes out more moist.

Using Cedar Plank for Grilling

  • Buy cedar planks: You can find them in the grill or seafood section of major grocery stores and online. Alternatively, buy untreated full cedar plank at Home Depot and ask an employee to cut it into 7-8 planks to save money.
  • Size: Be sure to buy cedar planks that are at least 5 inches wide and length depends on the size of your salmon. When I get my planks at a hardware store, I ask them to be cut into 13-15 inches long planks because we fish and our salmon is large.
  • Soak cedar plank: Soak wood in a sink with cold water for at least 1 hour and up to 24 hours. This is a vital step, so the planks don’t burn while grilling. Use a heavy glass dish or can to weigh the board beneath the water to ensure even soaking.
  • Wipe it dry: After soaking, you want to dry it with a kitchen towel or paper towels to ensure proper grilling.
  • Cedar planks can be soaked in advance and then frozen: That way, you don’t need to consider the hours of soaking every single time. Just soak it for anywhere up to 24 hours, lightly pat with a kitchen towel and then wrap in plastic wrap to store in the freezer. You can warm up plank on the grill before adding salmon or bring it to room temperature for 30 minutes before using.

Step by step process how to make cedar plank salmon on the grill.
  • Soak the cedar plank: Soak it for at least 1 hour. I usually do this in my kitchen sink using a few inches of cold water and a heavy meat mallet to weigh it down. Pat dry with kitchen towel before adding salmon.
  • Prepare Thai sweet chili glaze: Simply follow this Thai chili sauce recipe. It’s super simple to make by combining all the ingredients in a small pot and simmering for 10 minutes. If your grill has a side burner, you can cook the entire dish outside.
  • Grill salmon on a cedar plank: Preheat your gas grill or charcoal grill to medium-high heat around 450-500F. Then place salmon skin side down on the cedar plank and brush with some sauce. Grill covered for about 10 minutes.
  • Glaze the salmon more: Open the grill and brush salmon with remaining sauce. Then cover and grill for another 10 minutes or until cooked to your preferred level.

How Long to Grill Cedar Plank Salmon?

There are several ways you can check the cooked level of grilled cedar plank salmon.

Salmon will change from a deeper red color to a lighter opaque pink when cooked. Gently press the top of salmon with a fork and if it easily separates into tender flakes with a soft, moist center, then it’s ready.

We like to rely on an instant read thermometer to ensure our salmon is safe to eat. Here is a handy chart to consult when cooking salmon on the grill to your desired level of readiness.

Doneness levelInternal temperature
Rare115-120 F
Medium-rare120-130 F
Medium130-135 F
Well-done145 F or more

Recipe Tip

If salmon seems almost done, you can remove it from the grill and allow to rest a few minutes before serving. The salmon will continue to cook on the hot cedar plank.

Tips for Best Results

  • Keep a spray bottle with water on hand: Just in case the board catches on fire slightly, spray it with cold water. It shouldn’t happen but it’s good to be prepared.
  • If your salmon fillet doesn’t fit: You can tuck the end underneath the salmon fillet or cut it into thin strips and place on the sides of the board.
  • Grilling times vary: Cook time will vary based on the size and thickness of your salmon fillet plus your BBQ. If using individual small fillets, they may not need much longer after the initial 10 minutes, so keep an eye on them.
  • Keep skin on or off: It truly will not affect final results except only if you like grilled salmon skin, then do not remove it.
  • Do not reuse cedar planks: For food safety reasons, even if it’s not charred too much, do not use cedar plank to grill salmon second time. I’ve seen some sources say that it’s OK but I wouldn’t risk it. To save money, see my hardware store tip above! The charred wood can be used as a fire starter or broken up for smoking chips.
  • Extra smoky: Char cedar plank on the grill for a few minutes before adding the salmon fillet.

What to Serve with Cedar Plank Salmon?

Cedar plank salmon is excellent year-round and pairs really well with simple side dishes like grilled vegetables and roasted vegetables.

During the warmer months, pair it warm or cold with healthy salads like simple bell pepper salad and cucumber tomato feta salad. Make grilled romaine lettuce or grilled zucchini while cooked salmon is resting.

For a heartier salad, serve salmon with this Mediterranean orzo salad, Mediterranean pasta salad or Instant Pot potato salad.

In the cooler months, serve it up with heartier sides like mashed potatoes, grains like Instant Pot quinoa or Instant Pot brown rice, and roasted vegetables like roasted cauliflower.

How to Store and Reheat

Do you flip salmon when cooking on a cedar plank?

No, you don’t have to flip salmon when grilling it on cedar plank. Smoking wood will cook it until crispy on the bottom.

Can I use cedar fence board for grilling?

You can buy untreated cedar fence board at a hardware store and cut it into planks. Make sure it is labeled “untreated cedar”. Treated cedar wood is treated with chemicals and is not safe to consume.

Does cedar plank salmon taste like cedar?

No. Cedar plank salmon has woodsy and smoky taste but it doesn’t taste like cedar. It tastes smoked and grilled!

How do you keep fish from sticking to cedar planks?

Your salmon should not stick to a cedar plank. Slice cooked salmon with spatula into small fillets and you shouldn’t have problem serving it. It will not fall apart and will come off the plank if you use good wide and firm spatula.

  • 1 tablespoon cornstarch
  • 1 small garlic clove grated

  • Open the grill, brush salmon with remaining sauce, cover and grill for another 10 minutes or until the thermometer inserted in the deepest area reads 130 degrees F.
  • Cut salmon with spatula into 8 slices and serve warm right off the plank placed on a platter. You can brush salmon with more Thai sweet chili sauce, if desired.
