Grilled Ahi Tuna Recipe

A larger yellowfin or ahi tuna is even better for grilling because it has a higher fat content than a smaller fish. If you’ve never grilled tuna before, it’s easyβ€”and the marinade comes together quickly. Tuna on the grill is delicious because it can withstand the high heat and is incredibly flavorful.

Cook until the meat is medium-rare and serve it with some white basmati rice and a simple green salad. Alternatively, you can serve the tuna with a cold noodle salad, fresh asparagus that is in season, bok choy, or even boiled new potatoes that have been seasoned with butter, salt, pepper, and parsley.

According to Joan Velush, “this is a very straightforward and fresh preparation for ahi tuna that really lets the flavor of the fish come through. The marinade of lime juice, garlic, and fresh ginger livens up the taste, and adding a touch of honey at the end rounds the finished dish out nicely.
