It may sound fancy, but grilling seafood on a plank is much easier than grilling fish directly on the grates. The only trick you need to know is that if you are using a wooden plank, you’ll have to soak it in water first for at least 2 hours before grilling. Other than that, you simply place your fillets on the pre-soaked plank and cover your grill, and basically let it be until it’s done. No flipping required. You may have to adjust the position of the plank over lesser heat if your grill is extra hot and the fish is not quite done cooking. You’ll enjoy the subtle smoky flavor grilling on wood gives your food. Don’t want to use a wooden plank? Make one out of a double layer of heavy-duty aluminum foil. Spray the foil with cooking spray to prevent sticking.
