Garlic Herbed Grilled Tuna Steaks

Grilled tuna steak recipes aren't limited to restaurants. After enjoying yellowfin tuna in southwest Florida, I came up with this recipe so I could enjoy the flavor of my favorite fish at home. —Jan Huntington, Painesville, Ohio
  • Total Time
    Prep: 10 min. + marinating Grill: 10 min.
  • Makes
    4 servings


  • 2 tablespoons lemon juice
  • 1 tablespoon olive oil
  • 2 garlic cloves, minced
  • 2 teaspoons minced fresh thyme or 1/2 teaspoon dried thyme
  • 4 tuna steaks (6 ounces each)
  • 1/4 teaspoon salt
  • 1/4 teaspoon pepper


  • In a large resealable plastic bag, combine the lemon juice, oil, garlic and thyme. Add the tuna; seal bag and turn to coat. Refrigerate for up to 30 minutes, turning occasionally.
  • Remove tuna from bag; sprinkle with salt and pepper. Drain and discard marinade. Moisten a paper towel with cooking oil; using long-handled tongs, lightly coat the grill rack.
  • Grill tuna, covered, over medium-hot heat or broil 4 in. from the heat for 3-4 minutes on each side for medium-rare or until slightly pink in the center.

Test Kitchen Tips
  • Be careful not to marinate chicken and seafood for too long in acidic ingredients such as lemon juice or wine. The acid breaks down fibers and can cause a mushy texture if left on too long.
  • Common olive oil works better for cooking at high heat than virgin or extra-virgin oil. These higher grades have ideal flavor for cold foods, but they smoke at lower temperatures.

      Excellent, easy, Garlic Herbed Tuna cooked at mefium high heat, on the stove , using 5 thicker filet pieces, in a covered 6" pan . 3 to 4 minutes each side kept it moist, flavorful, with a less pink center. The lemon juice over powered the herbs. The recipe is a good base to add a pinch of other flavors .

      I love this recipe! I use about 2 bulbs of garlic with 2 tbsp of lemon juice and 3 tbsp of evoo. The extra garlic creates a nice crust.

      Absolutely WONDERFUL! I cooked the tuna on the grill and LOVED the flavor! The lemon adds just enough tartness to be distinguishable, but not too overpowering! EXCELLENT!!!

      I marinated the tuna steaks for at least a full hour and the flavor was great!
