Seared Ahi Tuna with Ginger Scallion Sauce

Ahi Tuna is a great source of lean protein, is very easy to cook, and can be on the table quickly for a healthy weeknight meal. My favorite preparation is seared and topped with a Ginger Scallion sauce served alongside rice and bok choy. This recipe is an adaptation from one if my all-time favorite cookbooks, Cook This, Not That.

The Ginger Scallion sauce is a combination of grated ginger, scallions, rice wine vinegar, soy sauce, and peanut oil. I’ve made it with sesame oil instead and it turned out well also. The sauce takes a bit more time to prepare but is so worth it! I always make a little more than what is needed for this meal so that we have extra in the fridge. It’s actually best if it has time to marinate together.

Fresh Ginger Root can be intimidating to work with but it’s fairly simple once you have the right tools. I use an upside down spoon to peel away the skin and a Ceramic Grater to grate which makes the process the pretty simple and quick.

This recipe is also great with the addition of Shitake Mushrooms. I like to add a dollop of Wasabi to bring in a little heat to the dish as well.
