Grilled Teriyaki Tuna Steaks with Grilled Pineapple & Green Onion

cup teriyaki sauce
can pineapple slices
teaspoon fresh garlic, peeled and finely diced
green onions
tuna steaks, 1" thick
salt to taste
pepper to taste


24 minutes

Preheat grill to medium-high (400-450 degrees).


Cut lemon in half and grill cut side down until slightly charred, about three to four minutes.


In a small bowl, whisk together the teriyaki sauce, pineapple juice, ginger, garlic, and one of the green onions, finely chopped. Use tongs to squeeze the juice from the lemon halves into the marinade, being careful to keep any seeds from the lemon from falling into the marinade.


Pour half of the marinade over the tuna steaks and let marinate for 30 minutes.


Simmer the other half of the marinade over medium-low heat until thickened, about 5-10 minutes. Remove and let cool.


Grill the pineapple slices until sear marks form, about 3 minutes per side. Grill the green onions until slightly charred, 1-2 minutes per side. Set aside.


Wipe excess marinade from the tuna steaks with a clean, dry cloth and season them on both sides evenly with several pinches of salt and pepper.


Place the tuna steaks on the grill and grill for four to five minutes for rare or five to seven minutes for medium rare. Carefully flip, brush the top with the glaze, and grill another four minutes for rare or five to six minutes for medium rare.


Flip one last time, brush the unglazed side with the glaze and let cook just long enough for the glaze to set, about one minute. Remove and serve.

      Hi Jazzy Jane,

      No worries. Green onions are also known as scallions, which have a milder taste than white onions.

      Happy Grilling!
