Prepare your marinade sauce by mixing soy sauce, garlic, ginger, lime juice, Worcestershire sauce, Italian seasoning, olive oil, and green onions in a zip-lock bag.
Leave the steak in the bag to marinate for 30 minutes to 2 hours in the refrigerator.
After marinating it, transfer the steak to a new zip-lock bag.
Place the bag in the Sous vide cooker after closing the bag entirely except one corner. Submerge the bag below the zip line in the water bath, then seal the opened corner.
Adjust the cooker to 130°F (54°C) after filling the sous vide container with water for medium-rare results.
Leave it to cook for 2-4 hours. At 2 hours’ time, the steak will be ready, but it’s up to you to leave it for more time.
When it’s done, transfer your steak to the refrigerator, let it cool for 10 minutes before searing.
Remove any excess moisture on the steak with a paper towel, then season it with salt and pepper.
Sear your steak on a grill set to 450°F (232°C) or a hot skillet on medium-high heat for 1 minute on each side.
After it’s seared, you can cut it immediately into thin slices and enjoy it with any steak sauce you prefer. You can also serve it on tacos, sandwiches or make it into a steak salad.
