Preparation

Step 1

To make marinade, place tamari, sesame oil, Sriracha, garlic and ginger in a medium bowl and whisk to combine. Pour marinade in a plastic zip-top bag, add tuna steaks and seal. Turn bag several times to coat tuna steaks with marinade. Place in refrigerator and marinate 1 to 2 hours.

Remove tuna steaks from zip-top bag, drain and discard excess marinade and pat dry. Place tuna on a large plate.

Prepare a hot charcoal fire, preheat a gas grill to high or heat a large grill pan over high heat. Brush grill grates or grill pan with a thin coating of oil using a silicone pastry brush. Sear tuna on both sides (when cooking the first/best side, when meat turns white 1/4 way up - turn the steak 1/4 turn to create hatch marks before turning over). Leave the interior rare to medium-rare, about 3-5 minutes per side, flipping once with a fish spatula or tongs. Transfer tuna to a cutting board with a well and let sit for 10 minutes.

To serve, cut the tuna steaks into 1/4-inch thick slices using a sharp slicing knife. Top each serving with a dollop of aioli. Garnish with green onions and sesame seeds. Serve immediately.
