3 Temperature Targets for Cooking Tuna Steaks
Rare at 115°F Pull the tuna off heat when it reaches 115°F for a cool, translucent center that preserves its buttery texture.
Medium-rare at 125°F Cook to 125°F for a warm, pink interior that still tastes fresh and moist.
Well-done at 135°F or higher Avoid cooking tuna past 135°F—it turns dry, flaky, and loses its flavor. Use an instant-read thermometer and rest the steak one minute before slicing.
