Ruth's Chris Ahi Tuna Recipe

Seared ahi tuna with a crisp, sesame-coated crust and a tender, ruby-red center is something I never get tired of.
The trick to getting that beautiful contrast is a super hot pan—cast iron is my go-to for the best sear.
Fresh, sushi-grade tuna is essential since it’s barely cooked, so don’t settle for anything less than top-quality fish.
I like serving it with a light ginger sauce that cuts through the richness and balances everything out.
A short cook time is the key—more than a minute per side, and you’ll lose that melt-in-your-mouth texture!
