All About Cedar Plank Salmon:

What does a cedar plank do for salmon? If you’ve never tried cedar-planked salmon, you are in for a treat! A cedar plank infuses the salmon with the subtle smokiness of the cedarwood, and also allows the fish to gently steam.

Whether you use the cedar plank on the grill or in the oven, this cooking method results in tender and wonderfully moist salmon every time. Plus, that soft and subtle woodsy flavor from the cedar makes this salmon irresistible!

We’ve shared several tips previously in our Cedar-Plank Sockeye Salmon with Hazelnut Vinaigrette recipe, so check that out for tips on where to buy a cedar plank and how to soak it.

The Ingredient List:

We use Wild Copper River King Salmon for this recipe, which is one of the finest salmon varieties out there, both in texture and flavor. However, if you can’t source Copper River Kings (or they’re not in season), no worries. This recipe will work with many salmon varieties.

How to make Cedar Planked Salmon:

To make cedar plank salmon, one of the first things you’ll need to do is soak the cedar plank. We soak it in water for at least two hours, and turn it halfway through to allow for even absorption of water on both sides.

Here’s a quick overview of the recipe. Scroll to the printable recipe card for all the details.

  1. Soak the cedar plank. This helps the fish stay extra moist while it cooks and it also prevents the cedar plank from burning.
  2. Season the salmon and heat the grill. Place the Thai chili sauce in a small pan and keep it warm on a back burner.
  3. Cook the salmon. Place the soaked cedar plank on the grill (without the salmon), close the top, and heat the plank for 2-3 minutes. Flip the plank and place the salmon on the hot cedar wood. Brush it with the chili sauce. Close the grill cover and finish cooking the salmon.
  4. Serve. Use a meat thermometer to check the temperature of the salmon. Serve it with the remaining warm chili sauce.

Recipe Tips

  • While we’re using Copper River King Salmon, you can prepare the fish this way with any species of salmon. Just be sure to adjust the cooking time based on the thickness of the salmon fillets you’re using.
  • Don’t skip soaking the cedar plank thoroughly before adding it to the grill! This will prevent the cedar from burning.
  • We recommend using a meat thermometer to easily monitor the internal temperature. The USDA recommended temperature for salmon is 145°F, which we personally feel is overdone and dry.

    We actually like our salmon cooked to an internal temperature of 122°F to 130°F. Check out our salmon doneness chart below to find your prefered doneness.
Rare (soft, buttery, juicy) 110°F
Medium rare (tender, flaky, moist) 125°F
Medium (flaky, firm, still has moisture) 130°F
Medium-well (dry, firm) 140°F
Well-done (dry and tough) 145°F
Salmon Temperature Guide

Remember to place your thermometer probe in the thickest part of the fillet and keep in mind that there will be carryover cooking. The salmon will continue to cook about 7°F to 10°F AFTER you remove it from the heat.

Frequently Asked Questions:

How long do you soak a cedar plank for salmon?

We recommend a minimum of two hours, flipping the plank after one hour of soaking so that both sides soak evenly.

Can you reuse cedar planks for salmon?

If the cedar plank is used on the grill, it may get pretty charred and might be unusable for a second time. You can reuse cedar planks if you feel they are in decent condition and you clean them well, however it’s best to use a fresh cedar plank each time.

This will also depend on how you prepare the salmon since the cedar plank will most likely take on the flavor of whatever sauce you used. Luckily, cedar planks are pretty inexpensive and you can often find them in packs of six or twelve (or more).

What temperature do you grill salmon on a cedar plank?

Whether you’re cooking cedar plank salmon on a grill or in the oven, we recommend a temperature of medium-high, about 350°F.

Do you flip fish on cedar plank?

There is no need to flip the fish on a cedar plank. If your salmon has the skin on, place the salmon pieces on the cedar plank with the skin side down.

Is cedar plank grilling healthy?

Yes, cedar plank grilling is simply a method of steaming the salmon and is a healthy way to prepare the fish.
