If you ask most salmon-loving people how to cook a salmon steak, there is just one answer: grill it. However, how to grill a salmon steak depends on one’s cooking preferences, though many a griller (especially in the Northwest) swear by cedar plank grilling.
To prepare the plank, soak it in water for 10 minutes or more (this will ensure that it doesn’t burn on the BBQ). Put a large piece of aluminum foil on the counter, put the cedar plank on the foil, put the salmon on the cedar plank. Season the salmon with your favorite seasoning. Lemon pepper is good, as is fresh dill and rosemary. Lemon slices also are an excellent addition. Fold the foil over the plank and the salmon so that everything is covered with foil. Flip the plank over and poke some small holes in the foil. You only do this on the side that has the cedar under the foil. 10 holes about the size of a pea will suffice.
How to cook salmon steaks seems to be a no-brainer (grill it) but timing is more based on preference. Some would say it is better to cook salmon too short of time than too long, as to avoid drying out the steak. Put the salmon on the grill with the hole side up first. Cook on this side for 4-5 minutes depending on how hot the grill is. Flip the salmon over and cook with the hole side down. You can cook a lot longer on this side because the heat travels through the cedar plank and then into the salmon. You could cook this side for about 10-15 minutes, depending on the heat of the fire and size of fish. You can open the foil and cut into the fish to ensure that it is ready. You want the center to be almost uncooked because it will cook a little when you take it off the grill. Leave it on the plank until ready to serve.
Many cooks believe salmon is better undercooked than over cooked, but once again, how to cook salmon steaks depends on personal preference-through grilling seems to be the unanimous method for cooking the perfect salmon steak.
