Ingredients

• 4 pieces (6-8 ounces each) Swordfish or tuna steaks
• 3 tablespoons Olive oil
• 3 tablespoons Lemon juice
• 2 tablespoons Soy sauce
• 3 cloves (minced) Garlic
• 2 teaspoons (finely chopped) Fresh rosemary
• 1 teaspoon Salt
• 0.5 teaspoons (freshly ground) Black pepper
• 0.25 teaspoons (optional) Red pepper flakes
• 1 tablespoon (for greasing the grill) Vegetable oil
• 4 pieces (for serving) Lemon wedges

Directions

Step 1

In a small mixing bowl, prepare the marinade by combining olive oil, lemon juice, soy sauce, minced garlic, chopped rosemary, salt, black pepper, and red pepper flakes, if using. Whisk until well blended.

Step 2

Place the swordfish or tuna steaks in a shallow dish or a resealable plastic bag. Pour the marinade over the fish, ensuring it coats all sides. Cover the dish with plastic wrap (or seal the bag) and refrigerate for at least 30 minutes, but no more than 2 hours.

Step 3

Preheat your grill to medium-high heat (about 375-400°F). Clean the grill grates thoroughly and lightly oil them with the vegetable oil to prevent sticking.

Step 4

Remove the fish from the marinade and let any excess marinade drip off. Discard the remaining marinade.

Step 5

Place the swordfish or tuna steaks directly on the preheated grill. Cook for about 4-5 minutes per side, depending on the thickness of the steaks, until they have clear grill marks and are cooked to your preferred level of doneness (aim for 125°F internal temperature for medium-rare tuna or 130°F for swordfish).

Step 6

Remove the fish from the grill and allow it to rest for 2-3 minutes before serving.

Step 7

Serve the grilled swordfish or tuna steaks with a lemon wedge on the side. Pair with your favorite sides, such as grilled vegetables or a fresh salad.
