How to cook tuna steaks?


  • 2 x 180 – 200g (6.5 – 7oz) tuna (skinless, boneless). 2.5-3cm / 1-1.2″ thick 
  • 1 tsp olive oil
  • 1/4 tsp sea salt
  • 1/8 tsp black pepper


  • 2 tsp olive oil, or oil spray

Serving suggestions:

  • Sauce Vierge (French salsa/vinaigrette for fish)
  • Chervil sprigs (small flat-leaf or curly parsley leaves can also be used) or small edible flowers (optional)


  1. Adjust a rack on a tray. A rack is encouraged instead of a plate especially in the case of tuna. Because tuna is highly susceptible to overcooking. A rack will prevent the tuna from becoming tough due to “Carry over cooking”.
  1. Smear the tuna with oil and sprinkle it with salt and pepper uniformly.
  1. Heat the skillet on the stovetop over high heat. The skillet with grille lines is ideal. However, you can also use a regular one.
  1. If you have a poorly seasoned skillet, grease it with some oil or cooking spray before heating it on the stovetop.
  1. Place one tuna at a time on the hot skillet. This is important to carefully cook the tuna to perfection. Because it takes only 30 seconds for tuna to go from rare to medium. So, this should be a critically controlled step. Cook one side for 45 seconds.
  1. Cook the same side for 45 ore seconds after rotating the fish by 45 degrees to get those perfect grill lines.
  1. Turn the tuna upside down and cook for 1 minute or until the internal temperature reaches 48°C / 118°F. Tuna feels too dry when cooked past medium-rare. So stick with this temperature.
  1. Let the tuna rest on a rack after removing it from the heat. Slice and serve after 5 minutes of cooling.
