Pro Tips: Sear the tuna for 1 minute on each side for rare; 2 minutes on each side for medium-rare; or 3 minutes on each side for medium. (If desiring medium-well or well-done sear the outside of the tuna in the pan 1 minute per each side and finish in a 350-degree oven on a baking sheet for 5 - 6 minutes so the tuna does not burn)
