Oak-Planked Peppercorn Tuna Steaks with Orange Mayonnaise

Press on a flavorful crust of cracked peppercorns before placing the tuna steak on an oak plank. Char one side of plank, then flip and place the fish on the darkened, smoke-infused wood for an extra boost of flavor.

  • Yield: 4 servings (serving size: 1 steak and 1 1/2 tablespoons orange mayonnaise)


  • 1 none (15 x 6 1/2 x 3/8-inch) oak grilling plank
  • 1/4 cup low-fat mayonnaise
  • 1/4 teaspoon grated orange rind
  • 2 tablespoons fresh orange juice
  • 2 teaspoons chopped fresh chives
  • 4 none (6-ounce) Bluefin tuna steaks (about 1 inch thick)
  • none Cooking spray
  • 1/2 teaspoon salt
  • 2 tablespoons mixed peppercorns, crushed


Immerse and soak plank in water for 1 hour; drain.

Prepare grill, heating one side to medium and one side to high heat.

Combine mayonnaise, rind, juice, and chives; stir well with a whisk. Chill.

Lightly coat top of tuna with cooking spray. Sprinkle the tuna with salt; firmly press peppercorns into tuna.

Place plank on grill rack over high heat; grill 5 minutes or until lightly charred. Carefully turn plank over; move to medium heat. Place tuna on charred side of plank. Cover and grill 10 minutes or until desired degree of doneness. Serve tuna with orange mayonnaise.
