A quick and easy grilled swordfish steak recipe featuring a tangy tomato caper relish that perfectly balances the fish’s rich flavor. Ideal for summer cookouts and casual gatherings.

Ingredients

  • Swordfish steaks (about 6 oz / 170 g each, thick cut)
  • Extra virgin olive oil (for marinade and grilling)
  • Fresh garlic (minced, about 2 cloves)
  • Fresh lemon juice (from about 1 lemon)
  • Sea salt (about ½ teaspoon)
  • Cracked black pepper (¼ teaspoon)
  • Cherry tomatoes (about 1 cup, halved)
  • Capers (2 tablespoons, drained)
  • Red onion (finely diced, about ¼ cup)
  • Fresh parsley (2 tablespoons chopped)
  • Red pepper flakes (optional, a pinch)

Instructions

  1. Prepare the marinade: In a medium bowl, whisk together 2 tablespoons of olive oil, minced garlic, fresh lemon juice, salt (about ½ teaspoon), and cracked black pepper (¼ teaspoon).
  2. Marinate the swordfish: Pat the swordfish steaks dry with paper towels. Place them in the marinade, turning to coat evenly. Let them sit at room temperature for 15-20 minutes.
  3. Make the tomato caper relish: Combine halved cherry tomatoes, diced red onion, capers, chopped parsley, a drizzle of olive oil (about 1 tablespoon), and a pinch of red pepper flakes if using. Toss gently and set aside.
  4. Preheat the grill: Heat your grill or grill pan to medium-high (around 400°F / 200°C).
  5. Grill the swordfish: Oil the grill grates lightly or brush the fish with olive oil. Place the swordfish steaks on the grill and cook for about 4-5 minutes per side until opaque edges and a firm but juicy center.
  6. Rest and serve: Remove the steaks from the grill and let them rest on a plate for 3 minutes. Spoon generous amounts of the tomato caper relish over the top and serve immediately.

Notes

Use thick-cut swordfish steaks for best grilling results. Marinate the fish at room temperature for 15-20 minutes to enhance flavor without cooking it. Keep the grill clean and well-oiled to prevent sticking. Flip the fish only once and rest it after grilling to lock in juices. If grill is too hot, use indirect heat after searing. Drain excess juice from tomatoes if relish becomes watery. For a low-sodium version, rinse capers or reduce quantity. Broiling is a good alternative if no grill is available.
