Ingredients

4 ahi tuna steaks sushi grade, 1.5 inches thick
2 teaspoons avocado or vegetable oil
2 teaspoons kosher salt
2 teaspoons cracked black pepper

Lemon Herb Butter

4 Tablespoons saled butter softened
2 teaspoons fresh thyme leaves finely chopped
2 teaspoons fresh Italian parsley finely chopped
1 teaspoon lemon zest

Instructions

Prepare the butter. Combine the softened butter with the thyme, parsley, and lemon zest. Set aside.
Preheat. Preheat your grill to very high heat (around 600-650 degrees F).
Prep the ahi tuna. Pat the tuna steaks dry with a paper towel, drizzle with avocado or vegetable oil, and season on both sides with salt and pepper.
Oil the grates. Oil the grill grates by folding up a paper towel and pinching it at the end of a pair of tongs. Dip the paper towel in a bowl of avocado or vegetable oil, allowing the oil to saturate the paper towel. Run the oiled paper towel over the preheated grates to coat them lightly.
Grill. Place the seasoned steaks on the grill, close the lid, and cook for 90 seconds before rotating 90 degrees, closing the lid, and cooking for an additional 90 seconds. Flip the steaks to the uncooked side, close the lid and cook for 90 seconds. Rotate 90 degrees again, close the lid, and cook for the final 90 seconds. Remove the tuna from the grill when it reaches 90-100 degrees F only if you have sushi-grade tuna. If you do not have sushi-grade tuna, cook the meat until it reaches 130 degrees F.
Enjoy. Move the seared tuna to your serving platter, top it with a dollop of the soft lemon herb butter, and serve immediately.
