Ingredients

• 4 pieces Fresh tuna steaks
• 4 tablespoons Olive oil
• 2 tablespoons Lemon juice
• 1 teaspoon Lemon zest
• 2 cloves Garlic cloves, minced
• 2 tablespoons Fresh parsley, chopped
• 1 tablespoon Fresh thyme, chopped
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper, freshly ground
• 1 lemon Whole lemon slices

Directions

Step 1

In a small bowl, combine olive oil, lemon juice, lemon zest, minced garlic, chopped parsley, chopped thyme, salt, and pepper. Whisk together until well blended.

Step 2

Place the fresh tuna steaks in a shallow baking dish and pour the lemon and herb marinade over them, ensuring they are well coated. Cover the dish and refrigerate for at least 30 minutes, allowing the flavors to meld.

Step 3

Preheat your grill to medium-high heat.

Step 4

Once marinated, remove the tuna steaks from the refrigerator and let them sit at room temperature for a few minutes.

Step 5

Lightly oil the grill grates to prevent sticking.

Step 6

Place the marinated tuna steaks on the hot grill. Grill each side for about 3 to 4 minutes, depending on the thickness of the steaks, until the exterior is nicely seared and the inside is slightly pink and tender. Avoid overcooking to prevent dryness.

Step 7

Remove the tuna steaks from the grill and let them rest a few minutes before serving.

Step 8

Serve the grilled tuna steaks garnished with lemon slices and additional fresh herbs if desired.
