A simple, flavorful marinade that tenderizes tuna steaks in 30 minutes, perfect for grilling or pan-searing.

Ingredients

Scale
  • 1/4 cup low sodium soy sauce
  • 2 tablespoons fresh lime juice
  • 1 tablespoon sesame oil
  • 1 tablespoon minced fresh ginger
  • 2 cloves garlic, minced
  • 1 teaspoon brown sugar
  • 1/2 teaspoon black pepper
  • 4 (6-ounce) tuna steaks

Instructions

  1. In a medium bowl, whisk together the soy sauce, lime juice, sesame oil, ginger, garlic, brown sugar, and black pepper to create the marinade.
  2. Place the tuna steaks in a resealable plastic bag or a shallow dish.
  3. Pour the marinade over the tuna steaks, ensuring both sides are coated.
  4. Seal the bag or cover the dish and refrigerate for 30 minutes. Do not marinate longer than 30 minutes to prevent the acid from changing the texture of the fish.
  5. Remove the tuna from the marinade and pat dry with paper towels before cooking. Discard the remaining marinade.

Notes

  • For grilling, aim for 2-3 minutes per side over medium-high heat for medium-rare.
  • If using a cast-iron skillet, heat the skillet until very hot before adding a thin layer of high-heat oil.
  • This marinade works well for ahi tuna steak.
