What Is Seared Ahi Tuna?
Seared ahi tuna is a dish made by briefly cooking the exterior of a tuna steak at very high heat while leaving the center rare or nearly raw. The term “ahi” refers to two species of tuna commonly used in cooking, the yellowfin tuna or bigeye tuna.
The tuna is typically seasoned or coated in spices or sesame seeds, then quickly seared in a hot pan or on a grill. The result is a contrasting texture, a flavorful crust outside and a silky, sashimi like interior.
Because tuna is naturally lean and delicate, cooking it quickly preserves its tenderness and flavor.
Often served in upscale seafood restaurants and Japanese inspired kitchens, seared ahi tuna is prized for its clean flavor, buttery texture, and beautiful presentation. The key to success lies in choosing excellent tuna and cooking it briefly at high heat so the exterior develops a savory crust while the inside remains rare.
Why You’ll Love Seared Ahi Tuna

Ingredients You Need
- Ahi Tuna. Fresh ahi tuna steaks are a must here, while you can use saku, which you can read about in this Tuna Crudo.
If you’re unfamiliar with the different types of fresh tuna, see more below. Look for tuna that is sushi grade or sashimi grade. It has to be firm in texture, deep red or pink in color, mild smelling and never overly fishy. Fresh or properly frozen tuna both work well. - Soy Sauce. This is the liquid coating for the fish and also a flavor booster. It adds the perfect umami.
- Cust. While you can use just a variety of sesame seeds, we added onion flakes, chilli flakes, coarse black pepper and dried oregano. Lime zest would be awesome here too! We don’t use salt as we have soy sauce and it replaces that.
What is Ahi Tuna?
So fresh tuna comes in two main varieties, the Ahi tuna or Albacore tuna. They both taste very similar but the main difference is their fat content. Ahi tuna is more fatty, and for that you’ll find that plenty of canned tuna is Albacore. Since tuna in general is not a fatty fish, it’s preferable to consume raw or slightly seared.

How to Choose the Best Tuna for Searing
The quality of the tuna dramatically affects the final dish.
Sushi Grade Tuna
For seared ahi tuna, sushi grade fish is ideal because the interior remains rare. This typically means the fish has been handled and frozen according to safety guidelines suitable for raw consumption.
Fresh vs Frozen Tuna
Frozen tuna can actually be excellent quality because flash freezing preserves freshness and texture.
Thickness of the Steak
Choose tuna steaks that are at least 1 inch thick. Thicker steaks make it easier to sear the outside without overcooking the center.
How to Sear Ahi Tuna
Step 1: Prepare the tuna
Pat the tuna steaks dry to ensure proper searing.
Step 2: Season the fish
The first step is to soak the piece of ahi tuna into a plate of soy sauce. Make sure you cover the entire fish, on all angles and all sides. This will infuse the fish tremendously with umami and saltiness from the soy sauce.
Next you’re going to prepare the crust. In a separate plate, add in the dry coarse crust ingredients. You can use just sesame seeds, or add in some flavor as we did here.
We used onion flakes, sesame seeds (white and black), dried oregano , chilli flakes, coarse peppercorn, a touch of sugar and dried ginger flakes. Alternatively you can find these coarse spice blends at the stores, and they work well here too.
Now take the tuna fillet and coat it well into the plate of dried ingredients until a thick sesame crust is formed. Make sure every side and angle of the fish is well coated.
Step 3: Heat the pan and Sear Quickly
In a hot pan or cast iron skillet with oil over medium-high heat. Sear the ahi tuna for just 1.5-2 minutes on each side at most, so 60-90 seconds or so. You want to have a nice crust on the outside while keeping the inside of the fish raw and soft.
Step 4: Rest briefly and Slice
At this point, remove the fish from the skillet, rest for a few minutes, and use a really sharp knife to slice the fillet into 1/4 th inch thick slices.
And there you have it, perfectly seared and sliced ahi tuna!
You can serve this right away, or have it cold. It’s delicious–SO delicious! We had it with our asian inspired Easy Cucumber Salad. And we also turned some leftovers into a phenomenal Poke Bowl!
Pro Tips for Perfect Seared Ahi Tuna
