The perfect seared ahi tuna recipe with crunchy sesame crust, a delightfully playful wasabi mayo and a mirin ginger dipping sauce. The best part of this recipe is looking through the translucent pink, stained glass window-like tuna after it has been seared and sliced. So beautiful it almost makes you not want to eat it... Almost.
THIS SEARED AHI TUNA RECIPE IS: GLUTEN FREE, PALEO AND LOW CARB. IT IS KETO WITHOUT THE MIRIN DIPPING SAUCE.
SEARED AHI TUNA RECIPE
I first fell in love with seared ahi tuna with a sesame seed crust in Nantucket. Caroline and I were there with her brother, some friends and a beautiful, fresh caught piece of tuna.
I remember clearly that the tuna was ruby red and perfect. Our friends pulled out some sesame seeds, wasabi and soy sauce. Within minutes, we were eating a mind blowing, simple and delicious appetizer.
This is the same recipe that I would like to share with you today. I hope that you enjoy it as much as we did.
Tips on Buying Ahi Tuna
One of the reasons I don't make this recipe very often is due to limited supply. It seems as though the tuna in the seafood cases just don't excite me, particularly with their extreme price tag.
When buying Ahi, you will either be buying yellowfin, bluefin or big eye tuna. They all fall under the Ahi category. What you are looking for is freshness. Ask the following questions:
- Ask when the fish arrived and if it was fresh or frozen. If it was frozen, ask when it was defrosted.
- Ask to smell it before you buy it as well. If it smells fishy, don't buy it.
- Ask if you can touch it before buying. It is okay- they can wash the fish before packaging. If it is slimy, don't buy it.
Ahi tuna should be fresh looking with a nice sheen to the steak. My one piece of advice: never buy Ahi tuna on sale.
You are looking for freshness because you're not going to be cooking it all the way through!
How to Sear Ahi Tuna
It's really easy to sear ahi tuna. Just follow these simple steps:
Step 1: Buy the best tuna you can find.
Step 2: Trim the tuna to allow as much of the protein to contact the pan as possible. See the image below on how I trimmed my ahi tuna for this recipe.
Step 3: Season the tuna. Salt and pepper is fine, or you can add sesame seeds like I've done below.
Step 4: Heat a heavy bottom pan over high heat. Add in the oil of your choice. When the oil is hot, add the Ahi tuna to the pan.
Step 5: Sear each side for 20-30 seconds dependent on the thickness of your tuna. The tuna shown is quite thick so adjust the cooking time accordingly.
Step 6: When seared on each side, remove the tuna from the pan and slice into ¼" pieces.

Prep Time15 minutes
Cook Time5 minutes
Total Time20 minutes
Ingredients
For the Wasabi Mayo
- ½ Cup Mayonnaise, store bought works fine
- 2 tablespoon Heavy Cream
- 2-3 teaspoon Wasabi Powder, depending on how spicy you like
- ½ teaspoon Braggs Liquid Aminos, Or soy sauce
- ½ teaspoon Honey
For the Mirin Dipping Sauce
- ¼ Cup Braggs Liquid Aminos, Or soy sauce

- 1 tablespoon Rice Wine Vinegar
- 1 tablespoon Pickled Ginger Juice
- 1 teaspoon Raw Honey
- 1 teaspoon Minced Green Onion
For the Seared Ahi Tuna
- 1 LB Sushi Grade Ahi Tuna
- 2 tablespoon White Sesame Seeds
- 2 tablespoon Black Sesame Seeds
- 3 tablespoon Olive or Grapeseed Oil
Instructions
For the Wasabi Mayo
- Add all ingredients to a bowl. Mix well with a fork to incorporate. If you have a squeeze bottle, pour into the bottle and decorate the plate.
For the Mirin Dipping Sauce
- Add all ingredients to a bowl. Mix well with a fork to incorporate. Set aside.
For the Seared Ahi Tuna
- Mix the sesame seeds on a plate. Lay the tuna on the seeds and press. Repeat on all sides including the ends.
- Heat a heavy bottom, stainless steel pan over high heat. Add the oil. When it is shimmering, but not yet smoking, carefully add in the sesame crusted tuna.
- Cook on each side for 20-30 seconds. When you flip, make sure you flip to a section of the pan that wasn't just cooked on. It will be hotter and create a nice crunchy sear. Make sure to sear the ends as well!

Notes
PLEASE KEEP IN MIND: The recipe is not KETO or LOW CARB if you are using the mirin dipping sauce. A good substitute is Braggs Liquid Aminos as a soy sauce alternative.

This looks delicious. My husband and I really want to try to make our own, but we've been too nervous/don't know where to buy a high quality tuna that won't break the bank. We will have to try this recipe. Certainly motivated me to look harder for that tuna!Reply

Thank you so much for this recipe and tutorial. I made this for a friend who is used to dining at 5 star restaurants and country clubs. He said it was "the best he ever had" and it was so easy to make. I love to try new recipes and often try them out on him, so the bonus came when he asked me to make this for a business meeting / dinner he was hosting in his home. It was a huge success!Thanks again!

Thanks for the tip on the powdered wasabi, made this last week really good so making it again tonight. Tip for good fish, have a boss/friend that goes to Mexican waters and brings you Yellowtail, Yellowfin and fresh caught Bluefin because you cover for him while he's gone.Reply
