Sear each side, flipping minimally. It should not take long for a crisp brown crust to form. Depending on the heat of your pan, it should take about 2-4 minutes (or less) for each side to finish cooking. When the first side is done, flip your steak and cook the second side for about as long.
Add the tuna steaks to the pan once the oil is fully heated and sear for about 2 to 4 minutes per side. Tuna steaks typically are between 1- to 1 1/2-inches thick.Searing the steaks for 2 to 4 minutes leaves the steaks done to rare or medium-rare. For more well-done steaks, add a few more minutes per side, but lower the heat slightly to avoid over-browning the outside.una steaks typically are between 1- to 1 1/2-inches thick.
