Tuna tends to dry out, especially the thinner steaks. Anything thinner than an inch and a half can be considered a thin steak. To keep a tuna steak from getting dry, it is a good idea to marinate it in oil and soy sauce.

Olive oil is one of your healthiest options. Not only will it keep your tuna from sticking to the grill, but it will also help to keep it moist. Drying out is less of a risk with thicker steaks so you may not need to marinate them. Simply brushing a little oil on before placing on the grill may be sufficient.
