Best Sesame-Crusted Sous Vide Tuna Recipe

This recipe was written by Stephanie Searor, MS RD LDN

Does your dinner routine need an update? Here’s a great, easy recipe for sesame-crusted tuna. The texture comes out perfectly rare, thanks to a low sous vide cook temp. Salting the meat and letting it rest is also the key to a silky, flavorful tuna steak.

This could be served immediately, or refrigerated until ready to serve. Thinly sliced with an assortment of pickled vegetables, steamed rice, soy sauce, and wasabi, and you’re ready for anything. Who needs to go out for dinner when you can make it at home?

The tuna could be cooked in a zip top bag or a vacuum seal bag, but the key to this recipe’s success is the sous vide circulator; the low, stable temperature ensure that the lean fish does not overcook or become tough.

Sesame Crusted Sous Vide Tuna Recipe

Sesame-Crusted Sous Vide Tuna

Prep time 45 minutes

Total cook time 90 minutes

Serves 2 as a main dish or 4 as a first course


  • 2 6-ounce fresh tuna steaks (or thawed if frozen)
  • 2 teaspoons Kosher salt
  • 2 tablespoons sesame oil
  • 1 ½ tablespoons sesame seeds (a mix of black and white is fun)


  1. Season the tuna liberally with salt, and let rest for 30 minutes. While the tuna is resting, prepare your sous vide container. Heat to 115 degrees Fahrenheit.
  2. After 30 minutes, drizzle the tuna steaks with one tablespoon of sesame oil, and press the sesame seeds into the top and bottom of the steaks (you can cover the sides, too, if you’d like).
  3. In a medium-hot pan, sear the tuna steaks for a minute on each side in another one tablespoon of sesame oil, or until the seeds are browned (but not burned).
  4. Once the steaks are seared, transfer to a vacuum seal bag or zip-top bag, making sure all air is removed. Submerge and cook for 45 minutes.
  5. Remove the steaks, and serve immediately or cool until ready to serve.

Serving suggestion: Tuna can be thinly sliced and served with wasabi, soy, steamed rice, and pickled ginger or daikon radish for an awesome, delicious dinner.
