Just a little background for anyone not familiar with the term ‘ahi’.  Ahi is the Hawaiian term for yellowfin tuna, a lean meat fish with a firm texture that is found in tropical and subtropical waters.

My husband and I are always inspired by our trips to Hawaii and we love to immerse ourselves in their food and culture.  Especially their food!  That’s not the easiest thing to do when you are trying to stay low-carb/keto but we try our best and always find solutions one way or another.

So when we go to a restaurant in Hawaii and can’t find anything low-carb/keto, one of our go-to menu items is always the ahi tuna with a side salad because we know it’ll always be a low carb filling dish.

It was one of these ahi tuna dishes that blew me away, a soy ginger ahi with a little kick at the end.  One bite and I knew I needed to try to replicate it at home!

After a few test tries and a few steaks of tuna, we came up with a new and improved ahi tuna dish that we call our Hawaiian glazed seared ahi tuna!

Just a quick note, make sure when cooking the ahi that you don’t overcook it, which results in a rubbery and dry fish.  The best way to avoid this is to sear the fish quickly leaving the center raw.  In steak terms, about rare to medium rare.

For this dish, the special ingredients you would need are Sesame OilSwerve/Monkfruit, Japanese Sake, Rice Vinegar, Soy Sauce, Wasabi Powder, Xanthan Gum and optional Toasted Sesame Seeds.  All these can be picked up on Amazon and an local Asian Supermarket.

Here is the sake we normally use for reference.  You can substitute the Japanese sake for Dry Sherry if needed.

Now, what are you waiting for?  Let’s get cooking!
