Grilling Marinades for Tuna Steak

Grilling Marinades for Tuna Steak – Well, it’s almost summer time and what better time than now to break out a few marinades for tuna steak to start out the grilling season!  I’ve assmebled several different recipes for you to try depening on the type of marinade recipe you like.  Everything from a simple soy sauce based marinade to a more complicated recipe with Orange and Ginger flavoring.

#1 Marinade for Tuna steak (Soy Sauce)Ingredients:

  • 3 tbsp. soy sauce
  • Juice of 1/2 lime
  • 1 tbsp. rice vinegar
  • 1 tbsp. sesame oil
  • Pinch dried red pepper flakes
  • 6 thin slices peeled fresh ginger
  • 2 garlic cloves, crushed


Blend all marinade ingredients in non-aluminum baking dish and add tuna steaks.  Or, even better, put in ziplock bags to maximize marinating the meat.

Cover and refrigerate at least 1 hour, but not more than 6 hours.

Turn once or twice.

Bring fish to room temperature.

Grill on preheated grill or broil in preheated broiler 4″ from heat.

Baste while cooking and turn once. Cook about 5 minutes each side. Do not over cook. Serves 4.

Swordfish, salmon or mahi mahi may be substituted for tuna.#2 marinade for grilled tuna steak (with oregano)
Now for a marinade with an Italian flavor using both oregano, basil and garlic.


  • 1/4 c. oil
  • 1 tbsp. oregano
  • 1 tbsp. basil
  • 2 tbsp. lemon juice
  • 2 cloves garlic

Mix all of the ingredients together.

Cover the tuna steaks with the marinade.  In a dish or in a ziploc bag.
