Preheat the Blackstone grill to as hot as it will get (approximately 500-700 degrees F).
Pat the tuna steaks dry. Rub the 1/2 the oil onto all sides of the tuna steaks.
Mix together the salt and pepper and pour it on a plate. Press both sides of the tuna steaks into the mixture to coat it with the seasoning mixture.
Drizzle the remaining oil onto the Blackstone Grill and use a spatula to spread it out.
Place the tuna steaks on the Blackstone Grill over the oil. Cook until well-seared and the tuna starts to release itself from the grill (approximately 1-2 minutes). Flip the tuna and cook the other side for 1-2 minutes as well until browned. You can also sear the short sides of the tuna by using tongs to turn the tuna steaks on their sides and grilling for a few minutes. If you measure the internal temperature of the tuna steaks they should be approximately 115-125 degrees F. The middle of the tuna should still be pink.
Remove the tuna from the Blackstone grill, slice the tuna against the grain and serve immediately.

Expert Tips

Cooking Tuna Steaks - We love cooking these tuna steaks to medium-rare. If you prefer them slightly more cooked, move the steaks over to indirect heat on the grill (turn off half of the grill) until it’s cooked to the temperature you prefer.
Seasoning - Season the tuna steaks with salt and pepper but you can easily use other types of seasoning.
Heat Griddle - Make sure the griddle is hot and oil before placing the tuna steaks on the griddle.
