Ingredients
- For the Swordfish and Marinade:
- 4 swordfish steaks, 6 oz each, about 1-inch thick
- ¼ cup extra-virgin olive oil
- 2 tablespoons fresh lemon juice
- 3 garlic cloves, minced
- 1 teaspoon smoked paprika
- 1 teaspoon sea salt
- ½ teaspoon freshly ground black pepper
- 1 tablespoon chopped fresh parsley
- For the Zesty Olive & Caper Relish:
- ½ cup kalamata olives, pitted and coarsely chopped
- 2 tablespoons capers, rinsed and chopped
- 1 small shallot, finely diced
- 1 tablespoon fresh lemon zest
- 2 tablespoons fresh lemon juice
- 3 tablespoons extra-virgin olive oil
- 2 tablespoons chopped fresh basil leaves
- Freshly ground black pepper, to taste
Instructions
- Prepare the Swordfish: Pat swordfish steaks dry with paper towels to ensure a nice sear. In a shallow dish, combine olive oil, lemon juice, garlic, smoked paprika, sea salt, black pepper, and parsley. Place the steaks in the marinade, turning once to coat thoroughly. Cover and refrigerate for 30 minutes to 1 hour, allowing flavors to penetrate.
- Mix the Relish: While the fish marinates, combine chopped kalamata olives, capers, shallots, lemon zest, lemon juice, olive oil, and basil in a small bowl. Stir gently and season with black pepper. Set aside at room temperature to let the flavors meld.
- Preheat the Grill: Heat your grill to medium-high (about 400°F). Ensure grates are clean and lightly oiled to prevent sticking.
- Grill the Swordfish: Remove steaks from marinade and let excess drip off. Place on the grill and cook for 5-6 minutes per side, until grill marks form and the fish is opaque but still moist inside. Avoid flipping more than once to keep the flesh intact.
- Rest and Plate: Transfer grilled swordfish to a warm platter and rest for 3-5 minutes. This step seals juices and enhances tenderness.
- Serve: Spoon a generous amount of the zesty olive & caper relish over each steak just before serving for that bold Mediterranean finish.
Tips for Success
- Selecting Swordfish: Opt for steaks that are firm,moist,and with a uniform thickness to guarantee even cooking and optimal flavor retention.
- Marinating: Avoid marinating longer than 1 hour,as the acidity can begin to “cook” the fish and alter its texture.
- Grilling Tricks: brush grill grates with oil using a folded paper towel and long tongs to prevent sticking. Use a fish spatula for gentle turning.
- Relish Variations: Add chopped sun-dried tomatoes or toasted pine nuts to the relish for extra complexity and texture.
- Make Ahead: The relish can be prepared up to a day ahead – store covered in the fridge and bring to room temperature before serving.
