Make your lemon ponzu sauce. In a bowl, toss lemon juice, lemon zest if you would like as well, ponzu sauce, thinly sliced scallions, sesame seeds and soy sauce. Set aside.
Prep your tuna. Make sure you’re getting sushi-grade fish! Prep and drizzle oil of your choice over it. In the meantime, layer sesame seeds (and/or) salt and pepper (I’m using black salt!) on a platter. Take your tuna and coat completely in the sesame seed mixture on all sides.
Sear tuna. In a nonstick skillet/hot pan with a drizzle of oil (of choice, but use a neutral oil), heat up your oil, add on your tuna sear for 30 seconds on each side on medium-high heat for a light sear and raw inside, until the outsides of the ahi are a lighter brown color and your seeds are toasted (but not burned), while keeping the inside more on the rare side.
*If you prefer your albacore tuna more medium rare or cooked all the way through, keep going until fully cooked, about 1-2 minutes on each side. This will also vary depending on the thickness of your steak.
Remove from the skillet, cool for 5 minutes, and sliced into thick cut slices.
Assemble your sliced albacore steaks and serve with your favorites sides and grains and drizzle over your lemon ponzu sauce. We are serving with fluffy white rice and garlic lemon broccolini.
