When you have quality ingredients, its always best to stay simple! This Miso & Sesame Crust Seared Tuna Steak recipe is a super quick 10 minute dish! The light miso dressing adds a little saltiness and contrast without overpowering the tuna. This recipe will cook your tuna rare (partially raw in the middle) but feel free to cook it longer depending on your preference. For some extra tanginess, accompany with the dipping sauce.
