Perfect Sous Vide New York Strip Steak

Ingredients

• 2 pounds New York Strip steak (about 1 inch thick)
• 1 teaspoon coarse salt or to taste
• 1/2 teaspoon black pepper or to taste
• 1 tablespoon olive oil divided
• fresh rosemary optional

Instructions 

1. Preheat sous vide machine: Add water to the sous vide container or a large pot, set the Sous Vide Precision Cooker to 135°F (57°C).
2. Season the steak: Rub the steak with 1/2 tablespoon oil on all sides.
3. Season both sides with salt and pepper.
4. Sous Vide the steak: Add the strip steak to a zip-lock bag together with optional rosemary.
5. Seal all but one corner of the bag, and slowly place it into a container with cold water. Make sure everything below the zip-line is covered by water. Then seal the rest of the bag.
6. Place the bag into the water bath in the sous vide container. Make sure it is fully submerged.
7. Sous vide cook for 1 hour.
8. Sear the steak: When the timer goes off, remove the bag from the water bath and transfer it to the fridge or an ice bath. Let it chill for about 15 minutes.
9. Remove the steak from the ziplock bag and wipe off the moisture with paper towels. Make sure to dry completely, otherwise it will interfere with the searing.
10. Season with more salt and pepper if necessary.
11. Place the cast-iron skillet on medium-high heat. Add the remaining olive oil. Once very hot, add the steak and sear about 1 minute per side.
12. Slice against the grain and serve immediately.
