Tuna steaks are a perennial favorite at Fish Tales Cafe, and for good reason. These meaty, versatile fillets offer a tender, flavorful canvas for a wide range of marinades and cooking methods. In this article, we’ll explore a zesty lemon-garlic marinade that elevates grilled tuna to new heights, perfect for your next backyard barbecue or elegant dinner party.
Types of Tuna
The most common tuna steaks you’ll find at the seafood counter include yellowfin (also known as ahi), albacore, bigeye, and bluefin. Yellowfin tuna is a popular choice, with a mild, delicate flavor and lean, firm texture that grills beautifully. Albacore is also commonly sold in steak form, though it tends to have a more pronounced “fishy” taste. Bigeye tuna is darker in color with a heartier, more robust flavor, while the prized bluefin variety is considered the most luxurious – and priciest – of the bunch.
Regardless of the type, the key to preparing exceptional tuna steaks is all about the freshness. Look for fillets that are bright in color, firm to the touch, and free of any discoloration or off-putting odors. If purchasing sushi-grade tuna, you can enjoy the steaks cooked rare or even completely raw, but for home cooking, it’s generally safer to opt for a quick sear or grill.
Tuna Preparation
Before marinating or cooking, rinse the tuna steaks and pat them dry thoroughly with paper towels. This ensures the marinade or seasonings will adhere properly. You can also lightly score the surface of the tuna in a crosshatch pattern, which helps the flavors penetrate deeper into the flesh.
When it comes to cooking methods, tuna is incredibly versatile. You can grill, pan-sear, broil, or even bake the steaks. For this recipe, we’ll focus on a simple grilling technique that delivers a nicely charred exterior while maintaining a warm, rare to medium-rare center.
Marinating Tuna Steaks
A well-crafted marinade is the secret to unlocking the full flavor potential of tuna. This zesty lemon-garlic version combines bright, zesty citrus notes with the savory punch of garlic, creating a balanced profile that complements the natural sweetness of the fish.
Lemon-Based Marinade
The foundation of this marinade is fresh lemon juice, which not only imparts a pleasant tartness but also helps to tenderize the tuna. Lemon juice contains enzymes that break down the proteins in the fish, resulting in a more tender, butter-like texture.
Garlic-Based Marinade
Minced garlic adds depth and complexity to the marinade, lending an aromatic, savory element that pairs beautifully with the lemon. The combination of citrus and garlic is a classic flavor pairing in Mediterranean and Middle Eastern cuisines, making it a natural fit for grilled tuna.
Marinade Ingredients
In addition to the lemon juice and garlic, this marinade also includes:
- Olive oil: Helps the marinade adhere to the tuna and prevents the fish from sticking to the grill grates.
- Soy sauce: Provides a subtle umami note that enhances the natural flavors of the tuna.
- Honey: Balances the acidity of the lemon with a touch of sweetness.
- Herbs: Fresh parsley, oregano, or thyme can all be added to the marinade for an extra burst of herbaceous flavor.
Simply whisk all the ingredients together in a shallow baking dish or resealable plastic bag, then add the tuna steaks and let them marinate for 30 minutes to 1 hour in the refrigerator. This allows the flavors to fully penetrate the fish.
Grilling Techniques
When it comes to grilling tuna, the key is to use high, direct heat to create a beautiful char on the exterior while keeping the interior rare to medium-rare. This helps to preserve the tender, buttery texture that makes tuna so appealing.
High Heat Grilling
Preheat your grill to medium-high or high heat. You want the grates to be hot enough to sear the tuna quickly, locking in the juices and preventing the fish from drying out. Lightly oil the grates before adding the marinated tuna steaks.
Indirect Grilling
For thicker tuna steaks, you can also use an indirect grilling method. Sear the fish over direct high heat for 2-3 minutes per side, then move it to the cooler, indirect side of the grill to finish cooking through, about 5-7 minutes more, depending on thickness.
Grill Maintenance
Be sure to keep the grill grates clean and well-oiled to prevent the tuna from sticking. You can also baste the steaks with the reserved marinade during the cooking process to keep them moist and flavorful.
Flavor Profiles
The bright, zesty flavors of this lemon-garlic marinade pair beautifully with the rich, meaty texture of grilled tuna steaks. The citrus notes help to balance the inherent fattiness of the fish, while the garlic and optional herbs add layers of complexity.
Citrus Flavors
The fresh lemon juice in this marinade provides a welcome tartness that awakens the palate. The grated lemon zest also contributes an aromatic, almost floral note that complements the tuna’s natural sweetness.
Garlic Flavors
Minced garlic infuses the marinade with a savory, pungent aroma that permeates the tuna as it grills. The heat of the grill also helps to mellow and mellow the garlic’s sharp edges, resulting in a deep, umami-rich flavor.
Herb Combinations
While the recipe here calls for a simple pairing of lemon and garlic, you can easily customize the marinade by adding fresh herbs such as parsley, oregano, or thyme. These aromatic botanicals introduce an herbaceous element that further enhances the tuna’s natural flavors.
When serving your grilled tuna steaks, consider pairing them with a crisp white wine, such as a Sauvignon Blanc or Albariño, which will help to cut through the richness of the fish. You can also serve the tuna over a bed of mixed greens or roasted vegetables for a complete, well-balanced meal.
