Sous Vide Tuna (Any Species) in Soy Citrus Marinade
The best way to eat tuna steaks is a near raw, rare perfection, best achieved with sous vide. There's no fear of overcooking and destroying the delicious (and not to mention, pricey!) tuna steak.
Ingredients
- 1 lb raw tuna, any species
Soy Citrus Marinade
- 1/4 cup soy sauce
- 1/4 cup fresh orange juice, about 1 orange
- 2 tbsp fresh lime juice, about 1 lime
- 2 tbsp fresh lemon juice, about 1/2 lemon
- 1 tbsp sesame oil
- 1 tbsp ponzu sauce, can replace with soy sauce
- 1 tsp crushed red pepper
- 1 tsp garlic powder
- 1/2 tsp kosher salt
Finishing
- 1/4 cup sesame seeds
- 1 tsp garlic powder
- 1 tbsp sesame oil
- 1/4 cup sliced green onions, green part only
- soy sauce, for dipping
Instructions
- If not cut already, slice tuna into steaks if desired. However, it's okay to leave as one big piece.
- Whisk together all ingredients for the marinade. Add the tuna to a large glass tupperware container or zipper top plastic bag and pour the marinade over it. Let marinate for at least 1 hour, up to 3 hours.
- Preheat a water bath using an immersion circulator to 110 degrees F for very rare, near raw tuna.
- Remove the tuna from the marinade and place into a vacuum seal bag. Vacuum seal or use another air removal method.
- Add the tuna to the water bath and cook for 30-45 minutes. Make sure the bag doesn't float; you can use sous vide magnets or place a ceramic plate on top.
- When done cooking, remove the bag from the water bath. Add the sesame seeds and garlic powder for finishing to a plate and mix together. Press the tuna steak(s) into the sesame seeds to coat on all sides of the steak.
- Preheat a cast iron skillet over medium high heat. When hot, add the sesame oil. Add the tuna and cook until sesame seeds are browned and tuna is seared, 30 seconds-1 minute per side.
- Remove the tuna to a cutting board and slice into 1/4 inch thick slices. Garnish with the green onions and serve with a bowl of soy sauce for dipping.
Notes
This tuna is delicious served with white rice.
Alternatively, serve this with a spicy mayo sauce. Mix 1/2 cup mayo with 2 tbsp sriracha, more to taste if desired. Cube the seared tuna and toss with the sauce.
