All Fired Up

Want to get excited about outdoor cooking? Grill some fresh fish.

Who doesn’t love to grill? It’s quick and easy and gets you out of the kitchen and into the backyard. Of course, as anyone can probably attest, grilling can be tricky at times. Doing it well requires a certain know-how. Otherwise food falls through the grill or turns out charred on the outside, undercooked on the inside.

My solution? Keep it simple and healthy by relying on classic Latin and Mediterranean seafood techniques. Don’t get me wrong: I love grilling pork, poultry and red meat, but when it comes to efficiency, fish rules. It’s easy on the waistline, too. Most species of fish average just a little more than a hundred calories for a 6-ounce portion. Even fish with higher oil content, such as mackerel or salmon, still top out at just less than 350 calories for a 6-ounce fillet and they offer a good dose of healthy omega-3 fatty acids in the bargain.

Smoke Alarm

If grilling has one drawback, it’s the potential buildup of heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs). HCAs are created when the amino acids from muscle meats are burned at high temperatures. PAHs, in comparison, enter the meat through the smoky flare-ups, which are caused when fat drips onto the coals (or flames in the case of gas grills). HCAs and PAHs can also form directly on food when it’s cooked too crisp. These chemicals are known to be carcin-ogens (cancer-causing), and while the question of how much cancerous cell damage they can do is up for debate, they should be avoided as much as possible.

Fish, though, can take much less time to grill than other meats, so HCAs and PAHs don’t have as much time to build up. Also, since fish are leaner than other animal proteins, they won’t drip as much fat.

Studies have shown that marinating foods also reduces PAH and HCA formation by cutting down on flare-ups. The trick, though, is to keep the marinade on the light side, since soaking fish in too much of anything will always cause flare-ups. But if you marinate in lightly acidulated vinegars, herbs, spices, chilies, garlic or citrus, you can add big flavors and still keep your fish healthy.

Warm-weather European and Latin American cooks have grilled this way for millennia. Traditional Mayan kitchens on Mexico’s Yucatan Peninsula rely on achiote, lime, orange, garlic and hot peppers to marinate fish in the pibil style. Most Mediterranean countries use fresh herbs, garlic, lemon and just enough olive oil to moisten fish and create a delicious, delicate crust.

Another technique shared by both cultures is that they usually roast their fish whole, over medium heat, using an indirect source. You can duplicate this method (even if you are just cooking fillets) by pushing the coals to one side of the grill and laying the fish on the opposite end. If you’re cooking on a gas grill, try using only a few of your burners to create the heat you need (roughly 400 degrees Fahrenheit) and place the fish on the part of the grill where the burner is off. This not only eliminates all possibility of flaring but also allows you to grill-roast the fish, which creates a crisp crust without any blackening.

More Grill Tips

  • USE THE FRESHEST FISH POSSIBLE. If your recipe calls for swordfish, but the freshest catch at the fishmonger’s is walleye, then go with the walleye.
  • KNOW WHERE YOUR FISH COMES FROM. Shop at a fish store with knowledgeable staff and ask questions: The farmed-versus-wild debate and use of sustainable fisheries are major concerns these days. I almost always prefer wild-caught seafood, but in many countries there are ecologically safe farm fisheries. Check out Monterey Bay Aquarium’s Seafood Watch list ( for the best choices.
  • RINSE AND PAT DRY YOUR FISH when you get it home, then marinate or cook right away. Buying and cooking it the same day is always best, but fish can spend a day on ice if it’s fresh enough.
  • ALWAYS KEEP YOUR GRILL CLEAN and the racks lightly coated with vegetable oil so foods cook properly and release easily. Keep spray bottles of water on hand for dousing flare-ups and olive oil or canola oil for lubricating sticky spots.
  • YOUR GRILL IS HOT ENOUGH when you can’t hold your hand over the coals for longer than a second or two from 6 inches away.
  • FIRM, FATTY FISH LIKE SALMON is the easiest to barbecue. The toughest: fine-fleshed, flat ones (say that three times fast), such as flounder. Also, steaks are easier to grill than fillets.
  • MARINATING CREATES FLAVOR and/or a crust, but overmarinating can turn your fish mushy or overwhelm its natural flavor. Marinating for just a few hours is plenty if you are using a strong rub, paste or liquid seasoning. Never marinate using papaya or pineapple, as they contain an enzyme that breaks down the flesh.
  • GRILLING TIME FOR WHOLE FISH VARIES between species, but a good rule to follow is 10 minutes for every inch of thickness.
  • THE FISH SHOULD BE FLAKY when cooked through, but some fish, such as salmon or tuna, are ideally cooked less than medium, and many people prefer them rare. White, firm-fleshed fish like snapper or halibut, while edible raw, tastes better when cooked just to the point of doneness.
  • USE A BUNDLE OF TIED ROSEMARY as a brush for basting fish on the grill. When almost finished, toss the herb bundle on the coals and continue cooking, covered, for a few minutes to infuse the fish with an herb-smoked flavor.
  • STUFF WITH LEMON SLICES, fork-mashed garlic and whole herb sprigs for an intense flavor boost.
  • IF YOU WANT A SMOKY FLAVOR, soak dried grapevine cuttings, fruitwood chips or hardwood chips in water and then toss on the coals.
