Why I Love This Recipe

This Hawaiian-inspired dish features fresh ahi steaks seasoned and pan-seared to perfection, served with a delightful soy sauce dipping sauce!

Just like in my Sesame Seared Ahi Tuna and Seared Yellowfin Tuna Tataki dishes, I simply season the ahi steaks and pan-sear them to perfection, eliminating the need for marinating, unlike my Seared Marinated Tuna recipe. It’s a fantastic main dish that delivers spicy, savory ahi tuna with a satisfying umami kick from the dipping sauce. If you’re seeking an easy and healthy recipe using fresh ahi tuna steaks, this one is a must-try! I promise you will love it!

🍽️ Ahi Serving Notes

Pairing Recommendations

Your Blackened Ahi Tuna can be complemented by serving a refreshing green salad tossed in Miso Dressing, providing a delightful contrast to the bold flavors of the tuna. For added texture and taste, consider a side of Wakame Seaweed Salad or Wasabi Avocado Salad. To complete your meal, a bowl of Clam Miso Soup brings comforting warmth that pairs perfectly with the seared ahi tuna.
