Grilled Swordfish Built for Peak Summer Cooking

Chef’s Overview

Dear Chefs, grilled swordfish is one of those summer recipes that feels impressive without asking you to babysit the grill all evening. Its firm texture, clean flavor, and beautiful sear make it perfect for warm-weather cooking, especially when you pair it with citrus, herbs, olive oil, and a few simple chef moves. Today, we’re walking through how to prep, season, grill, and serve swordfish so it stays juicy, flavorful, and built for the kind of summer meal that deserves a cold drink nearby.

Ingredient List

For the Swordfish

• 4 swordfish steaks (about 6 ounces each)
• 3 tablespoons olive oil
• 2 tablespoons fresh lemon juice
• 1 tablespoon fresh orange juice
• 2 garlic cloves, minced
• 1 teaspoon lemon zest
• 1 teaspoon kosher salt
• ½ teaspoon black pepper
• ½ teaspoon smoked paprika
• ¼ teaspoon crushed red pepper flakes
• 1 tablespoon chopped fresh parsley
• 1 tablespoon chopped fresh basil

For Serving

• Lemon wedges

Step-by-Step Recipe

Step 1: Prepare the Swordfish for Even Cooking

Pat each swordfish steak completely dry with paper towels before placing them on a cutting board. Check for any dark bloodline, uneven edges, or small pieces of skin that you would like to remove. The 5" VG-10 Damascus Petty Knife makes quick, clean work of trimming while preserving as much of the fish as possible. Starting with evenly prepared steaks helps every piece finish cooking at the same time, just like we emphasized in Crisp Skin Branzino with Fennel Pollen.

Step 2: Build a Bright Citrus Herb Marinade

In a medium bowl, whisk together the olive oil, lemon juice, orange juice, garlic, lemon zest, kosher salt, black pepper, smoked paprika, crushed red pepper flakes, parsley, and basil until fully combined. The citrus brightens the fish while the herbs add fresh summer flavor without overpowering the natural richness of the swordfish.

Step 3: Marinate Without Letting the Citrus Take Over

Place the swordfish steaks into a shallow dish or resealable bag and coat them evenly with the marinade. Let the fish rest for 15 to 20 minutes at room temperature while the grill preheats. Avoid marinating much longer because the citrus can begin changing the texture of the fish before it ever reaches the grill.

Step 4: Preheat the Grill for a Perfect Sear

Heat your grill to medium-high, around 400 to 450°F. Once hot, brush the cooking grates clean and lightly oil them using a paper towel held with tongs. Clean, well-oiled grates help prevent sticking and make it much easier to flip the swordfish without tearing the surface.

Step 5: Grill the First Side Without Moving the Fish

Lay the swordfish steaks directly over the heat and leave them untouched for about 4 to 5 minutes. Resist the temptation to peek underneath too early because the fish will naturally release once a proper sear develops. This patience creates the deep grill marks that give swordfish its signature summer presentation.

Step 6: Flip Carefully and Finish Cooking

Using a wide fish spatula, gently flip each steak and cook for another 3 to 5 minutes depending on thickness. The swordfish should reach an internal temperature of about 130 to 135°F and remain slightly translucent in the very center before resting. Like many seafood recipes, carryover cooking will finish the job once the fish comes off the grill.

Step 7: Give the Fish a Short Rest

Transfer the grilled swordfish to a clean platter and allow it to rest for 3 to 5 minutes before serving. This short resting period gives the juices time to redistribute throughout the fish, helping every bite stay moist instead of running onto the plate the moment it's cut.

Step 8: Finish With Fresh Herbs and Citrus

Right before serving, squeeze fresh lemon over each steak and finish with chopped parsley, basil, and a light sprinkle of flaky sea salt. Those final touches wake up the smoky flavors from the grill while adding freshness that perfectly complements the richness of the fish.

Step 9: Pair With Fresh Summer Sides

Serve the swordfish alongside grilled asparagus, a bright cherry tomato salad, grilled corn, or warm crusty bread. Keeping the sides simple allows the grilled fish to remain the centerpiece while creating a meal that feels light enough for warm evenings outdoors.

Step 10: Slice and Plate Like a Chef

If you're serving the swordfish family style, use the 8" VG-10 Damascus Gyuto to portion each steak into clean, even slices without tearing the delicate flesh. A sharp knife preserves the beautiful texture you've worked to create while giving every plate a polished presentation. The same attention to detail carries through recipes like Chicken Souvlaki Built for Summer Grilling, where careful slicing makes the finished dish look just as impressive as it tastes.

Step 11: Add One Final Taste Before Serving

Before everyone gathers around the table, take a quick moment to taste one piece of the fish. A small squeeze of additional lemon, another pinch of flaky sea salt, or a few extra herbs can brighten the entire dish. Professional kitchens constantly make these final adjustments, and it's often the difference between a good meal and one people talk about long after dinner.

Step 12: Enjoy Peak Summer Cooking

Serve the swordfish immediately while it's still warm from the grill and enjoy it with family or friends around the patio table. The smoky char, bright citrus, and fresh herbs come together in a way that feels effortless yet memorable. Recipes like this prove that peak summer cooking isn't about making things complicated—it's about letting great ingredients, thoughtful technique, and dependable kitchen tools do exactly what they were designed to do.

The Grill Does the Heavy Lifting When the Prep Is Right
