Step 1

Fill the sous vide container with water and set the sous vide cooker for your desired degree of doneness. See the table in the notes section below.

Step 2

While the water comes up to temperature season the sirloin steak with salt and pepper.

Step 3

Either seal the steak using a vacuum sealer or place it in a heavy duty ziploc bag and use the water displacement method to remove most of the air from the bag.

Step 4

To use the water displacement method seal the bag most of the way and slowly lower it in the water, letting the water pressure push out most of the air. See this post for a detailed description of the water displacement method.

Step 5

Cook the steak in the water for 1 1/2 to 4 hours.

Step 6

About 5 minutes before you want to eat prepare to sear the steak. Heat a heavy frying pan over medium high heat on the stove.

Step 7

Remove the bag from the water and open it. Use a paper towel to dry the steak off. Add the oil or butter to the frying pan once it is hot. Then quickly sear the steak for 1-2 minutes on both sides to brown it.
