Sesame Seared Tuna with Orange Soy Reduction

This might be my daughters favorite fish... Just seared, silky, succulent, and sesame! It simply melts in your mouth. This sesame seared tuna with the intense and flavorful reduction finished with sesame seeds and fresh cilantro for a little crunch and pop of flavor. So delicious, so healthy, and so easy it's an any time meal!

Marinated Tuna

  • 1 1/2 lbs fresh wild tuna (I used 3 steaks about 1 1/4 inches thick, my family likes this so much we usually make more than we might otherwise eat)
  • 1/4 cup tamari (or other soy sauce if you are good with the gluten)
  • 2 tbsp fresh ginger, grated
  • 1 tbsp sesame oil (plus a little for searing)

Orange Soy Reduction

  • 1/2 cup fresh orange juice
  • 2 tbsp tamari (other soy is fine as above)


  • 1/4 cup cilantro, chopped
  • 2 tbsp sesame seeds (I used a mixture of toasted white and black sesame seeds)



  • Add the tuna steaks to an airtight container.
  • Grate the ginger over top of the tuna. Pour on the sesame oil and the tamari over the steaks.
  • Close the container and shake well to coat.
  • Refrigerate while marinating.

Orange Soy Reduction

  • Add the orange juice and tamari to a sauce pan.
  • Over medium heat, reduce by half, about 15 minutes, you may need to turn the temperature down a little as you go to keep it from burning.

Searing the Tuna

  • Remove tuna from refrigerator about 20 minutes before you want to sear to come to room temperature (can probably do this when you're about to make the reduction).
  • Get a large skillet pretty hot, medium-high. Add a little sesame oil and swirl to coat the pan.
  • Place tuna steaks into pan so they lay flat and have a little space between them. Sear each edge for about 45 seconds to a minute. Using a spatula (and maybe some tongs) turn to the next edge and repeat. Usually this is 5 sides for me because of the triangular shape of the steaks. May require some balancing against each other when you are searing a smaller edge!
  • Remove to a cutting board. Sprinkle with sesame seeds and slice thinly.
  • Add to a plate and dribble a bit of the orange soy reduction around and on top then sprinkle with the chopped cilantro and enjoy!


NB: Consuming raw or undercooked meats, poultry, seafood, shellfish, or eggs may increase your risk of foodborne illness.
That being said, I can't say enough about how delicious this sesame seared tuna is! I haven't had any issues using a good source of tuna but I have to share the warning!
