This easy soy sauce based tuna marinade adds deep umami flavor perfect for searing or grilling tuna steak.

Ingredients

Scale
  • 1/4 cup low sodium soy sauce
  • 2 tablespoons rice vinegar
  • 1 tablespoon sesame oil
  • 1 tablespoon fresh grated ginger
  • 2 cloves garlic, minced
  • 1 teaspoon brown sugar
  • 1/2 teaspoon black pepper

Instructions

  1. In a medium bowl, whisk together the soy sauce, rice vinegar, sesame oil, grated ginger, minced garlic, brown sugar, and black pepper until the sugar dissolves.
  2. Place your tuna steaks in a sealable plastic bag or shallow dish.
  3. Pour the marinade over the tuna, ensuring both sides are coated.
  4. Refrigerate for 15 to 30 minutes. Do not marinate longer than 30 minutes to prevent the fish from becoming mushy or tasting too salty.
  5. Remove the tuna from the marinade, pat dry with paper towels before cooking. Discard the remaining marinade.

Notes

  • For grilling, preheat your grill to medium-high heat.
  • This marinade works well for quick searing; aim for 1 to 2 minutes per side for medium-rare.
  • If you prefer a citrus marinade for tuna steak, substitute 1 tablespoon of the rice vinegar with fresh lime juice.
