Ingredients

• 2 pieces (8 oz each) Flat iron steaks
• 1 teaspoon Kosher salt
• 1 teaspoon Freshly ground black pepper
• 1 teaspoon Garlic powder
• 2 sprigs Fresh rosemary
• 2 tablespoons Unsalted butter
• 2 tablespoons Olive oil

Directions

Step 1

Fill a large pot or sous vide container with water and attach your sous vide immersion circulator. Preheat the water bath to 130°F (54°C) for medium-rare or adjust to your desired doneness.

Step 2

Season both flat iron steaks generously on all sides with kosher salt, freshly ground black pepper, and garlic powder.

Step 3

Place each steak in a resealable freezer bag or vacuum-seal bag. Add one sprig of fresh rosemary to each bag.

Step 4

If using resealable bags, use the water displacement method: slowly lower each bag into the water bath, letting the pressure of the water push out the air, then seal the bag completely. If using vacuum-sealed bags, seal them before placing them in the water.

Step 5

Submerge the steaks in the preheated sous vide water bath and cook for 1.5 hours (90 minutes).

Step 6

When the steaks are done cooking, carefully remove the bags from the water bath. Remove the steaks from the bags, pat them dry with paper towels, and discard the rosemary sprigs.

Step 7

Heat a cast-iron skillet over high heat until it is smoking hot. Add the olive oil and let it heat for 30 seconds.

Step 8

Carefully place the steaks into the skillet and sear for about 1 minute on each side, until a deep brown, caramelized crust forms.

Step 9

Add the unsalted butter to the skillet along with any remaining rosemary sprigs. Tilt the skillet slightly and use a spoon to baste the steaks with the melted butter for additional flavor.

Step 10

Remove the steaks from the skillet and let them rest for 5 minutes before slicing and serving. Enjoy your perfectly cooked flat iron steaks!
