About this recipe

For this recipe, I rubbed the ahi tuna steak with my homemade blackening spice. The blackening spice adds a layer of flavor to the ahi tuna that tastes amazing. The slightly spicy rub, paired with the soft delicate fish is the perfect combination. You will want to make sure you buy ahi tuna steak for this recipe. Sushi grade ahi tuna steaks can be found fresh or in the freezer section of your local grocer. It is completely safe to eat this fish raw or seared rare, which is how it is prepared for this recipe.

How to sear ahi tuna steaks

When prepping the ahi tuna, you will want to let it sit at room temperature for 10 minutes. Then, you will pat it dry using a paper towel to absorb any excess moisture. Removing the excess moisture allows you to get a perfect sear on the fish.

Generously rub the fish with the blackening spice, making sure every side is well coated before searing. Heat a non-stick skillet over medium high heat. Add about 1 tablespoon of vegetable oil to prevent the tuna steak from sticking to the pan. Once the pan and oil are hot, add the fish. Sear for 45-60 seconds per side. Flip the fish using tongs so that all four sides get an even sear. This will give you a seared rare temperature. If the tuna steak is thin you may want to adjust your cooking time.

Allow the seared ahi tuna to cool before slicing it into thin, even slices. Make sure you use a sharp knife so that the slices are neat and clean. No serrated edges. If you do not eat the seared ahi tuna steak right away, be sure to cover it and refrigerate it before enjoying.

Prepare the vegetables and garnishes

When prepping the vegetables be sure to cut them in even sized pieces. Be sure to scrape out the core of the cucumber using a spoon. This will prevent the dish from getting watery. I like to julienne or thinly slice my cucumber and bell peppers. This makes them easy to pick up and enjoy.

As far as garnishes and sauces go, feel free to get creative. I used soy sauce mixed with wasabi along with a homemade peanut sauce as dip. However, spicy mayo or ponzu sauce would also taste amazing with these blackened ahi tuna bowls. Additional options are sliced avocado, fresh lime wedges, crush peanuts, scallions or furikake. Feel free to add whatever toppings you like to these blackened tuna bowls.

This recipe makes four light dinner servings or two hearty servings. Please see below for nutritional information. The nutritional information reflects the peanut sauce as well.
