Authentic Spanish Grilled Swordfish with Fresh Tomato-Herb Salsa

There is something undeniably magical about Spanish cuisine—it manages to be incredibly simple yet bursting with complex, vibrant flavors. This Spanish Grilled Swordfish recipe is the perfect embodiment of that philosophy. Swordfish is known as the "steak of the sea" because of its firm, meaty texture, making it the ideal candidate for grilling on the Arteflame. It holds up beautifully to high heat, developing a delicious, smoky crust while remaining moist and tender on the inside. When paired with a rustic, bright tomato-herb salsa, the richness of the fish is perfectly balanced by the acidity and freshness of the toppings. Whether you are hosting a summer dinner party or looking for a healthy, protein-packed meal for your family, this dish transports you straight to a seaside taverna in Andalusia. By utilizing the unique heat zones of the Arteflame grill, you can achieve that restaurant-quality sear without drying out the delicate meat.

Ingredients

The Fish

• 4 fresh Swordfish steaks (about 1 inch thick)
• 3 tbsp Extra virgin olive oil
• Sea salt, to taste
• Freshly cracked black pepper, to taste

Spanish Tomato-Herb Salsa

• 4 ripe Roma tomatoes, diced (seeds removed)
• 2 cloves garlic, minced finely
• 2 tbsp fresh basil, chopped
• 1 tbsp fresh mint, chopped
• 1 tbsp fresh parsley, chopped
• 1/4 cup red onion, finely diced
• 1 tbsp capers, drained (optional for a salty kick)
• Juice of 1/2 lemon
• 1 tbsp Sherry vinegar (or red wine vinegar)
• 3 tbsp Extra virgin olive oil
• Salt and pepper, to taste

Instructions

Step 1: Prepare the Arteflame Grill

1. Start by building a fire in the center of your Arteflame grill. You want to get the grill grate hot and ready for searing.
2. Allow the fire to burn down slightly so the cooktop reaches an optimal searing temperature (usually about 15-20 minutes).
3. Lightly oil the cooktop surface with vegetable oil or olive oil to prevent sticking and to help create a beautiful golden crust on the fish.

Step 2: Make the Tomato-Herb Salsa

1. While the grill is heating up, prepare the salsa. In a medium mixing bowl, combine the diced tomatoes, minced garlic, red onion, and capers.
2. Add the chopped fresh herbs: basil, mint, and parsley.
3. Drizzle with the olive oil, lemon juice, and sherry vinegar. Season generously with salt and pepper.
4. Toss everything gently to combine. Let this mixture sit at room temperature for at least 10 to 15 minutes. This allows the flavors to meld together and the tomatoes to release their juices, creating a natural sauce.

Step 3: Season the Swordfish

1. Pat the swordfish steaks dry with paper towels. Removing excess moisture is crucial for getting a good sear.
2. Brush both sides of the steaks with extra virgin olive oil.
3. Season liberally with sea salt and freshly cracked black pepper. Press the seasoning gently into the flesh so it adheres during grilling.

Step 4: Grill the Swordfish

1. Place the swordfish steaks directly onto the center grill grate for a high-heat sear. Sear for about 2 to 3 minutes per side until you see nice grill marks and a golden crust.
2. Once seared, move the steaks onto the flat carbon steel cooktop (the outer ring). This area is cooler and allows the fish to finish cooking through without burning the outside.
3. Cook for another 3 to 4 minutes depending on thickness, or until the internal temperature reaches 130°F (medium). The fish should be opaque and flake easily with a fork.

Step 5: Assemble and Serve

1. Remove the swordfish from the grill and let it rest for 2 minutes.
2. Plate each steak and spoon a generous amount of the fresh tomato-herb salsa directly over the top.
3. Garnish with an extra wedge of lemon and serve immediately while hot.

Tips for the Perfect Swordfish

Grilling swordfish requires a bit of finesse to ensure it remains juicy rather than turning into a dry hockey puck. The most critical tip is to avoid overcooking. Swordfish has a low fat content compared to salmon, so it dries out quickly if left on the heat too long. Aim for medium doneness; the residual heat will continue to cook the fish as it rests. Always bring your fish to room temperature for about 15 minutes before grilling; cold fish on a hot grill cooks unevenly. Furthermore, when making the salsa, try to find the ripest tomatoes possible. Since this is a raw sauce, the quality of the produce dictates the final flavor profile. If your tomatoes are a bit lackluster, a pinch of sugar can help mimic natural sweetness. Lastly, ensure your Arteflame cooktop is well-oiled before placing the fish down to ensure a seamless flip and a pristine crust.

Variations

While the classic tomato-herb combination is a staple in Spanish coastal cooking, this recipe is incredibly versatile and can be adapted to suit your palate or whatever ingredients you have on hand. You can lean into different flavor profiles by swapping out just a few components of the salsa or the marinade. Here are a few ways to mix things up:

• Spicy Kick: Add a diced jalapeño or a pinch of crushed red pepper flakes to the salsa for some heat.
• Citrus Burst: Swap the lemon juice for orange juice and add some orange zest for a sweeter, fruitier profile.
• Olive Tapenade Style: Add chopped Kalamata or green olives to the salsa for a brinier, more savory depth.
• Mediterranean Butter: Instead of salsa, finish the grilled fish with a compound butter made with garlic, smoked paprika, and lemon zest.
• Verde Style: Skip the tomatoes and make a green sauce using parsley, cilantro, garlic, olive oil, and lime juice.

Best Pairings

To turn this Spanish Grilled Swordfish into a complete feast, you want sides that complement the acidity of the salsa and the meatiness of the fish without overpowering them. Since you already have the Arteflame fired up, it makes sense to utilize the grill for your side dishes as well. The goal is to keep the meal light and fresh, consistent with the Mediterranean diet.

• Grilled Asparagus: Toss with olive oil and lemon zest, then grill on the flat cooktop until tender-crisp.
• Patatas Bravas: Dice potatoes, grill them on the flat top until crispy, and serve with a spicy paprika aioli.
• Spanish Rice: A side of saffron-infused yellow rice with peas makes for a classic accompaniment.
• Crusty Bread: Grilled baguette slices rubbed with garlic are perfect for soaking up the juices from the salsa.
• Wine Pairing: A crisp Spanish white wine, such as Albariño or Verdejo, cuts through the richness of the fish perfectly.
