This easy tuna marinade recipe uses soy sauce and ginger to create a flavorful preparation for searing or grilling tuna steaks quickly. It is designed to add great taste without over-marinating the delicate fish.

Ingredients

Scale
  • 1/4 cup low-sodium soy sauce
  • 2 tablespoons fresh lime juice
  • 1 tablespoon sesame oil
  • 1 tablespoon grated fresh ginger
  • 2 cloves garlic, minced
  • 1 teaspoon brown sugar
  • 1/2 teaspoon red pepper flakes (optional)

Instructions

  1. In a medium bowl, whisk together the soy sauce, lime juice, sesame oil, grated ginger, minced garlic, brown sugar, and red pepper flakes until the sugar dissolves. This is your flavorful tuna steak prep.
  2. Place your tuna steaks in a shallow dish or a resealable plastic bag.
  3. Pour the marinade over the tuna, ensuring both sides are coated.
  4. Marinate the tuna for a maximum of 15 minutes at room temperature, or up to 30 minutes in the refrigerator. Do not marinate longer to prevent the fish from becoming mushy.
  5. Remove the tuna from the marinade and pat it dry with paper towels before cooking. Discard the remaining marinade.
  6. Grill or sear the tuna steaks according to your preference.

Notes

  • For searing tuna, aim for a very hot pan to get a nice crust while keeping the center rare.
  • If you prefer an Asian style tuna marinade with more citrus, increase the lime juice by one tablespoon.
  • Always pat the tuna dry before cooking; excess moisture prevents a good sear.
  • This quick tuna steaks marinade works well for grilling marinade for tuna.
