By Steven Raichlen, 5-time James Beard Award-winner and Barbecue Hall of Famer

The summer air, thick with the scent of charcoal and blooming jasmine, often sparks a culinary question: what’s the ultimate grilled delight? For many, the immediate answer is a perfectly seared steak or succulent ribs. However, for esteemed barbecue maestro Steven Raichlen, the true star of the summer grill is fish. And nowhere does this aquatic delicacy truly shine, he asserts, than when kissed by the flames at his summer sanctuary on Martha’s Vineyard.

Yet, the mere mention of "fish on the grill" can conjure images of disaster for even seasoned grill enthusiasts. The specter of sticking, the fear of falling apart, and the dread of a dry, overcooked fillet haunt the imaginations of many. Raichlen, a five-time James Beard Award-winner and inductee into the Barbecue Hall of Fame, acknowledges these anxieties. Grilling fish, he explains, is not always a simple undertaking. It’s an art form that requires understanding, precision, and, most importantly, the selection of the appropriate grilling technique tailored to the specific type of fish.

The Foundation of Flavor: Choosing the Right Grilling Method

Raichlen’s extensive experience has led him to develop a nuanced approach to grilling fish, categorizing the most effective methods to ensure success, regardless of the fish’s texture or density. His philosophy centers on matching the fish to the fire, transforming potential pitfalls into triumphs of flavor and texture.

Direct Grilling: The Bold Approach for Firm Fish

For those who crave a robust char and a primal connection to the grill, direct grilling is the method of choice. This technique, involving the direct exposure of fish to the intense heat of the fire, is ideally suited for firm, meaty steaks. Think of robust options like swordfish, tuna, and salmon. These varieties possess a structural integrity that allows them to withstand high temperatures and the delicate maneuver of flipping without disintegrating.

The cornerstone of successful direct grilling, Raichlen emphasizes, lies in meticulous preparation. "Start with a hot, clean, well-oiled grill grate," he advises. This foundational step is crucial for preventing adhesion. Before the fish even graces the grates, patting it dry is essential; moisture is the enemy of a good sear. A light brushing of oil on both the fish and the grate further acts as a non-stick barrier.

The real magic of direct grilling unfolds when the fish meets the heat. Raichlen’s mantra is patience: "Once the fish hits the grate, leave it alone long enough to develop a good sear." Resist the urge to prod or move it prematurely. A well-seared surface will naturally release from the grate, signaling that it’s time for the flip. When that moment arrives, a thin-bladed spatula is your most trusted ally. And, in the pursuit of perfection, Raichlen advocates for a singular flip whenever possible, minimizing the risk of breakage and preserving the integrity of the fillet. Swordfish, with its dense, steak-like texture, remains a particular favorite for Raichlen under this direct grilling regime, a testament to its exceptional suitability for this bold approach.

Indirect Grilling: The Gentle Embrace of Heat

When dealing with whole fish or larger, more delicate specimens, the gentle embrace of indirect grilling offers a more forgiving and equally rewarding path to perfectly cooked seafood. This method transforms the grill into a sophisticated outdoor oven, where the fish is cooked away from the direct flames, allowing for even cooking and a more controlled environment.

"Indirect grilling is ideal for whole fish, like snapper or salmon," Raichlen explains. Instead of placing the fish directly over the coals, it is positioned to the side, with the grill lid closed. This creates a convection-like heat circulation, ensuring that the fish cooks uniformly from edge to center. This is particularly beneficial for larger fish that require a longer cooking time, preventing the exterior from drying out before the interior is cooked through.

The preparation for indirect grilling is similar in its emphasis on oiling the fish. Seasoning inside and out enhances the flavor profile. For those seeking an elevated smoky dimension, Raichlen suggests introducing wood chunks or chips to the fire. "For an extra blast of wood smoke, toss a few wood chunks or chips onto the fire," he recommends. This subtle infusion of smoky essence elevates the inherent flavors of the fish, creating a dish that is both succulent and deeply aromatic.

Smoking: Unlocking the Depths of Flavor

For a select group of fish, the allure of wood smoke is an irresistible siren song. Oily fish, in particular, have a remarkable capacity to absorb the complex nuances of smoke, emerging from the smoker with a depth of flavor that is simply unparalleled. Salmon, bluefish, and whitefish, with their inherent richness and natural fat content, are prime candidates for this technique.

"Few foods take to wood smoke as enthusiastically as oily fish," Raichlen notes. The fat content acts as a natural basting agent, keeping the fish moist throughout the smoking process while simultaneously carrying the smoky essence into every fiber. To achieve optimal results, Raichlen suggests a preliminary step: brining or curing the fish. This not only imparts flavor but also helps to firm up the flesh, making it more resilient during the smoking process. Crucially, allowing the surface to dry before smoking is essential for optimal smoke adherence.

The choice of wood is as important as the fish itself. Alder is the classic and revered wood for smoking salmon, its mild, sweet profile perfectly complementing the fish’s richness. However, Raichlen encourages experimentation, noting that apple, cherry, and other mild hardwoods also yield beautiful results. The finished product can be enjoyed immediately, hot from the smoker, or chilled for a delightful cold-smoked experience.

Griddling and Planchas: The Solid Surface Solution

For the most delicate of fish fillets, where the open grate of a traditional grill can be a source of anxiety, the griddle or plancha emerges as a hero. These flat, solid cooking surfaces offer a forgiving alternative, providing the intense heat and satisfying sizzle of grilling without the risk of delicate flesh sticking or falling through the bars.

"For delicate fish fillets—think sole, flounder, or black bass—a griddle or plancha can be your best friend," Raichlen states. The broad, uniform surface ensures that the fish is in constant contact with the heat, promoting even cooking and a beautiful crust. The key to success here is preheating the griddle to a high temperature, followed by a light application of oil. As with direct grilling, allowing the fish to sear undisturbed before attempting to turn it is paramount. A thin-bladed spatula remains the tool of choice for a clean and confident flip. The griddle and plancha offer a method that is both accessible and rewarding, allowing even novice grillers to achieve professional-level results with fragile fish, while still capturing that coveted live-fire flavor.

The Grill Basket: A Protective Cage of Flavor

When the inherent fragility of the fish, or the apprehension of the griller, dictates a need for extra security, the humble grill basket proves its worth. This simple yet effective tool acts as a protective enclosure, safeguarding delicate fish from the perils of sticking, tearing, or disappearing through the grate.

"A grill basket is cheap insurance for fish that has a tendency to stick, tear, or fall through the grate," Raichlen explains. It is particularly useful for smaller whole fish, such as trout and snapper, as well as for delicate fillets like halibut and turbot. The principle is straightforward: oil the basket thoroughly before introducing the fish. Once the fish is securely clamped within the basket, the entire unit is turned, eliminating the need for precarious spatula maneuvers. This significantly reduces the risk of the fish adhering to the grill, allowing for a more relaxed and enjoyable grilling experience while still capturing the essential elements of heat, smoke, and char.

Cedar Planking: Aromatic Infusion and Foolproof Cooking

Planking, particularly with cedar, represents one of the most foolproof and flavorful methods for grilling fish. The cedar plank acts as a natural barrier between the fish and the grill grate, simultaneously infusing the fish with a distinctively woody aroma as it heats.

"Planking is one of the most foolproof ways to grill fish," Raichlen asserts. This method is ideal for fillets such as salmon and striped bass, where the risk of sticking and falling apart is significantly mitigated. For an added layer of complexity, Raichlen suggests charring one side of the plank over the fire before placing the fish upon it. This pre-charring intensifies the smoky notes. The plank, bearing the seasoned fish, is then moved away from direct heat, allowing the cedar to gently steam and perfume the fish while it cooks. The result is a moist, succulent, and wonderfully aromatic fillet.

Salt Slab Grilling: A Mineral Kiss of Perfection

For an avant-garde approach that elevates both flavor and presentation, the salt slab offers a unique grilling experience. Heating a block of Himalayan pink salt on the grill transforms it into a sizzling, mineral-rich cooking surface, akin to a high-end plancha.

"A salt slab turns your grill into a sizzling, mineral-rich plancha," Raichlen describes. This method is particularly well-suited for delicate whole fish, such as snapper, black bass, and porgie. The solid surface of the salt slab prevents the fish from falling through the grate, while the gradual heating process, crucial to prevent cracking, ensures even cooking. As the fish sears on the hot salt, it absorbs a subtle, yet distinct, minerality that enhances its natural flavors. The beautiful crust achieved on the exterior, combined with the gentle seasoning from the salt, creates a truly memorable dish.

Grilling in Leaves: Ancient Wisdom, Modern Appeal

Harkening back to ancient culinary traditions, grilling fish wrapped in leaves offers a primal and flavorful method that is both practical and aromatic. This technique, prevalent across Asia, Latin America, and the Caribbean, is particularly effective for delicate fish, providing a natural barrier against the grate and trapping moisture for an exceptionally succulent result.

"Wrapping fish in leaves is an age-old grilling technique found throughout Asia, Latin America, and the Caribbean," Raichlen notes. Banana leaves are a popular and effective choice, readily available and imparting a subtle, herbaceous aroma as they char. The process involves softening the leaves, often by briefly passing them over the grill, before wrapping the seasoned fish securely within. Toothpicks can be used to hold the package together. The leaves absorb the direct heat of the fire, effectively steaming and smoking the fish within. The result is a perfectly cooked, incredibly moist fillet, free from the woes of sticking and falling apart, and opening the package at the table releases a fragrant cloud of steam, a true sensory delight.

Grilling on a Stick: Primitive Prowess and Camping Charm

For the adventurous spirit, or those seeking a truly elemental grilling experience, the sharpened stick and wood fire method offers a direct and engaging connection to the cooking process. This primitive technique is perfectly suited for camping or any situation where a traditional grill setup is unavailable.

"Sometimes the simplest grilling equipment is a sharpened stick and a good wood fire," Raichlen muses. By positioning the fish beside embers rather than directly over flames, radiant heat becomes the primary cooking force. Threading the fish securely onto a sturdy stick or stake allows for easy maneuvering. By angling the stick toward the fire, and adjusting its proximity to the embers, precise control over the cooking temperature is achieved. This method not only eliminates the concern of sticking to a grill grate but also provides a satisfyingly rustic and hands-on approach to grilling fish.

The Crucial Moment: Knowing When It’s Done

Regardless of the chosen grilling method, the ultimate success of grilled fish hinges on one critical factor: knowing precisely when it has reached its peak of doneness. Raichlen underscores the importance of precision, stating, "There’s a fine line between perfectly cooked fish and fish that’s dry enough to make you reach for the tartar sauce. Don’t guess. Use an instant-read thermometer."

The insertion point for the thermometer varies depending on the cut of fish: for whole fish, probe the thickest part of the flesh just above the bone; for fish steaks, insert the probe through the side to the center. The target internal temperatures provide a reliable guide:

• Most Fish: 140°F to 145°F (60°C to 63°C)
• Blue Tuna: 100°F to 110°F (38°C to 43°C)
• Rare Tuna: 120°F to 125°F (49°C to 52°C)
• Medium-Rare Tuna: 130°F to 135°F (54°C to 57°C)

Raichlen highlights that tuna, with its unique characteristics, operates under a different set of rules. The key, regardless of the cooking method, is to ensure the center remains beautifully rosy, a hallmark of perfectly cooked tuna.

The Enduring Appeal: Fish, Fire, and the Summer Season
