Whole Fish Basics
Most fish varieties work fairly interchangeably. Some great mild, white-fleshed varieties that typically come in sizes that feed two to four diners include snapper, black sea bass, branzino, perch and porgy. Some more strongly flavored varieties (often called “oily fish”) include mackerel, bluefish, and trout. Sardines and smelts are very small fish and have special cooking requirements.
If you’re cooking whole fish for the first time, consider a smaller size (1 to 1 1/2 pounds) for easy handling. You’ll also want the fish scaled, and the guts and gills removed. It’s not difficult to do yourself, but your fishmonger can do a quick and expert job for you too.
Unless you’re squeamish, leave on the head and tail for best cooking results. But by all means lop off either if you find your fish won’t fit in the pan! Cutting a few slashes into the side of the fish with a sharp knife lets heat and flavorings into the flesh; cut deeply but not all the way to the bone for most effect.
Seasonings & Aromatics
For the simplest seasoning, rub the fish inside and out with olive oil and sprinkle with salt and pepper. You can also stuff some aromatics like herbs, fennel, lemon or green onions in the cavity of the fish for more flavor and aroma.
Cook the fish just until the flesh flakes with a fork. Overcooking fish dries it out and impairs its flavor, so start checking your fish a few minutes before you think it might be done. Most fish will cook best if turned only once; turning more often risks having the fish fall apart.
What to do about that shrunken eye staring out as you present the cooked fish on a platter? I sometimes stuff a green olive or round piece of bell pepper into the socket to make it look more appetizing, but by all means don’t fuss if it doesn’t bother you or your guests.
A whole grilled fish is nothing less than spectacular, taking on the subtle flavors of smoke and caramelizing the skin in a ways that are both delicious and aromatic. Make sure your grill grate is scrupulously clean (rub it vigorously with a wire brush to remove any debris) to prevent sticking. You can and use a grill basket to help in turning smaller fish if you like, but two spatulas should also work well.

Small fish can be easily pan-seared in a heavy skillet over medium heat. This is best for small fish like sardines, porgy, or trout; ideally you’ll want the fish 8 ounces or less to make sure it cooks evenly through. Use a generous amount of oil in your skillet will make sure the fish doesn’t stick and aid in even heat transfer. A stovetop steamer is also a great way to cook smaller fish: Line the bottom of the steamer with vegetables or a lettuce leaf to help removing it from the basket easy, place the fish on top, and place over simmering water.
Don’t overlook the microwave for whole fish; it does a fantastic job steaming and is ideal for mild-flavored white fish. Put your cleaned fish in a baking dish, partially cover it with a lid, and microwave on high until the fish flakes, somewhere around 5 minutes for a 1-pound fish.
