Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 6-10 minutes
• Total Time: 3 hours 15 minutes (includes marinating)
• Servings: 2
• Dietary Type: Gluten-Free, Dairy-Free

Ingredients

• 2 swordfish steaks (sliced no more than 1-inch thick)
• 4 tablespoons olive oil (reserve 1 tbsp. for brushing grill rack)
• 1 tablespoon balsamic vinegar
• 1 tablespoon lemon juice
• 1 garlic clove, minced
• 1 teaspoon fresh thyme, chopped
• 1 teaspoon fresh rosemary, chopped
• 1 teaspoon fresh sage, chopped fine
• 1⁄2 teaspoon salt (or to taste)
• 1⁄4 teaspoon black pepper, freshly ground (or to taste)

Equipment Needed

• Zip-lock bag
• Small bowl
• Grill

Instructions

1. Place the swordfish steaks in a zip-lock bag, leaving the bag unsealed for now. This allows us to introduce the marinade effectively.
2. In a small bowl, combine 3 tablespoons of olive oil with the balsamic vinegar, lemon juice, minced garlic, chopped fresh thyme, chopped fresh rosemary, finely chopped fresh sage, salt, and freshly ground black pepper. This mixture forms the flavorful Italian marinade that will tenderize and enhance the fish. Whisk together until well combined.
3. Pour the prepared marinade into the zip-lock bag with the swordfish steaks. Gently toss the fish with your fingers, ensuring that each piece is thoroughly coated in the marinade. The marinade needs to come into full contact with the swordfish for the flavors to properly infuse.
4. Seal the zip-lock bag, releasing as much air as possible. This helps ensure the marinade is in close contact with the swordfish during refrigeration.
5. Marinate the swordfish in the refrigerator for 3 to 4 hours. This allows the flavors to penetrate deeply and the acid in the marinade to slightly tenderize the fish.
6. Preheat your grill to medium-high heat. This is crucial for achieving those beautiful grill marks and ensuring the swordfish cooks evenly.
7. Once the grill is searing hot, brush the grill rack with the remaining 1 tablespoon of olive oil. This will prevent the swordfish from sticking to the grill and create a lovely sear.
8. Grill the swordfish for 3 to 5 minutes on each side, or until the center of the steaks is cooked through. A telltale sign of doneness is when the fish flakes easily when tested with a fork. Be careful not to overcook, as swordfish can become dry. The exact cooking time will depend on the thickness of the steaks and the heat of your grill.

Expert Tips & Tricks

• Don’t over-marinate: While marinating is crucial for flavor, leaving the swordfish in the acidic marinade for too long (over 4 hours) can cause the texture to become mushy.
• Pat the fish dry: Before grilling, gently pat the marinated swordfish steaks dry with paper towels. This helps them sear beautifully on the grill, rather than steaming.
• Use a fish basket: For delicate fish like swordfish, a fish basket can be a lifesaver. It prevents the fish from sticking to the grill and makes flipping much easier.
• Check for doneness: The best way to check if the swordfish is cooked through is to insert a fork into the thickest part of the steak. If it flakes easily and the internal temperature reaches 145°F (63°C), it’s ready.
• Rest the fish: After grilling, let the swordfish rest for a few minutes before serving. This allows the juices to redistribute, resulting in a more tender and flavorful steak.

Serving & Storage Suggestions

Serve the Grilled Italian Marinated Swordfish hot off the grill, garnished with a sprig of fresh rosemary or thyme and a squeeze of fresh lemon juice. It pairs beautifully with a variety of sides, such as a simple green salad, grilled vegetables, or a creamy risotto.

For leftovers, allow the swordfish to cool completely before storing it in an airtight container in the refrigerator. It will keep for up to 2 days. Reheat gently in a skillet over low heat or in the microwave, taking care not to overcook it. You can also flake the cold swordfish and use it in salads or sandwiches. Freezing is not recommended, as the texture can become rubbery.

FAQs (Frequently Asked Questions)

Q: Can I use dried herbs instead of fresh?
A: While fresh herbs are preferred for the most vibrant flavor, you can use dried herbs if that’s what you have on hand. Use about 1/3 of the amount called for in the recipe, as dried herbs are more concentrated.

Q: How can I prevent the swordfish from sticking to the grill?
A: Make sure your grill is very hot and well-oiled before placing the fish on it. You can also use a fish basket or grill mat to further prevent sticking.

Q: Can I marinate the swordfish overnight?
A: It’s not recommended to marinate swordfish for longer than 4 hours, as the acid in the marinade can break down the texture of the fish and make it mushy.

Q: How do I know when the swordfish is cooked through?
A: The best way to check for doneness is to insert a fork into the thickest part of the steak. If it flakes easily and the internal temperature reaches 145°F (63°C), it’s ready.

Q: What if I don’t have a grill?
A: You can also cook the swordfish in a skillet on the stovetop or bake it in the oven. If baking, preheat your oven to 400°F (200°C) and bake for 10-15 minutes, or until cooked through.
