Grilling with solid hardwood planks can add a smoky twist to your favorite grilled meats and foods.
Plank grilling is a very simple concept. Instead of grilling directly on the surface of your cooking grate, you place your food on a slab of wood and cook the whole thing on your grill. There is little prep work involved, and the results can range from subtle to spectacular. You get a smoky taste unique to the chosen hardwood without the preparation and time required for traditional smoking or wood-fired grilling. Using a plank is especially well-suited for users of propane grills because it adds flavor without using charcoal.
The Plank
While cedar is most commonly used, grill planks come in a variety of other hardwoods including alder, mesquite, oak, maple, hickory, cherry, peach, and apple. Some are more appropriate for grilling specific foods than others, but it doesn't hurt to experiment or use the type that's most readily available in your area. Just make sure that you use untreated planks so you don't introduce any harmful chemicals or nasty flavors into your food. It's also best to avoid woods with a high resin content, such as pine or birch. You can find grill planks at gourmet cooking stores, but be creative! Gas Grill Fanatics have found many sources of grill planks. Check grocery, specialty food, or hardware stores. Lumberyards and cabinet shops may even cut planks to fit your grill. Make sure to buy untreated wood no thicker than 1 inch. Thinner planks will work fine, but they tend to crack and burn more than thicker planks. The upside is that thin, disposable planks require less cleanup. If you can't find good wood planks locally, you can order grill planks online at Northwest Plank Company, Outdoor Gourmet, or Currier & Reeves. Or just google "grill planks" for even more options.
Preparation
The secret to using planks for grilling is soaking them in advance. This prevents the wood (and your food) from burning up in your grill and also gives the wood better smoking qualities to impart that smoky flavor to your food. Immerse your plank in water and soak for at least 4 hours or overnight. If your plank floats, just weigh it down with canned goods or a heavy bowl.
Technique
After your plank has soaked, and you're ready to grill, brush the cooking side of your plank with vegetable oil to prevent food from sticking. If your plank is new, toast both sides on your grill for a few minutes before using. Place your food on the center of the plank, and then place the prepared plank on your hot grill. Make sure your grill is pre-heated to medium or high heat. Check your food periodically to make sure your plank isn't flaring up. Keep a water-filled spray bottle handy to spritz any flames on your plank. If you're grilling meat or fish, you may want to coat it with barbecue sauce, fresh herbs, or spices during the second half of its grilling time. Once your food is done, you may remove it from the plank to serve, letting the plank cool on your grill's cooking grate. However, one of the great things about plank grilling is that it makes for a great presentation. Just be careful with that schorching-hot piece of wood.
