Seared Ahi Tuna
Ingredients
- 2 Ahi Tuna Steak fresh
- 1/4 cuo Soy Sauce
- 2 tablespoon sesame seeds
- 1 tabelspoon black sesame seeds
- 1 Tablespoons onion flakes
- 2 teaspoons Ginger flakes
- 1 teaspoon garlic granules
- 1 teaspoon light brown sugar
- 2 teaspoons chilli flakes
- 1 teaspoon oregano
Instructions
-
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 crust is formed. Make sure every side and angle of the fish is well coated.
-
In a hot pan, with oil, sear the ahi tuna for just 1.5-2 minutes on each side at most. You want to have a nice crust on the outside while keeping the inside of the fish raw and soft.
-
At this point, remove the fish from the skillet 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!

Why Is My Tuna Overcooked?
Cooking the fish too long can turn the center grey and dry. To fix this, use higher heat and reduce cooking time.
Why Didn't My Tuna Form a Crust?
A proper crust requires high heat and dry fish. To fix this, pat the tuna dry and ensure the pan is very hot.
Why Is My Tuna Sticking to the Pan?

Because tuna has a delicate flavor, proper seasoning is essential. To fix, make sure you season as recommended in the recipe, and you can add extra sauces on the side.
How to Make In Advance
This is a great recipe to prepare ahead of time. You can sear the fish and wrap it in the fridge for up to 2 days before slicing and serving. It's best not to marinate the fish for more than 30 minutes in soy sauce as it will begin to cure. In that case, it will still taste great, but loose the texture, similar to a Tuna Ceviche.
How to Get the Perfect Sear?
Have your pan super hot, and well oiled. Then sear the tuna for 1.5 minutes without flipping or touching. Flip and cook another 2 minutes and remove it from the pan.
Can Tuna fall apart when searing?
If your pan is not too hot, or if you don't have enough oil, these may cause the fish to crumble. Also the thickness of your tuna fillets along with how your flip it around the pan can make it fall apart. Make sure your fish is about 3/4 inch thick and only flip it once during searing.
