Before my first attempt to make seared tuna, I was daunted by its sophistication. It wasn't until after that I realized the dish is deceptively foolproof — unlike chicken, you don't have to worry about whether it's cooked through!
Since the outside is seared quickly at high heat and the center of the steak is rare, the fish takes no time to cook. If you prefer more well done tuna, simply increase the cooking time. When searing the tuna in batches, be sure to add another 1 1/2 tablespoons oil for the second round of tuna.
