Season the steak with the salt, pepper, herbs,
and garlic. Put the steak in a plastic bag and vacuum seal the bag.
Set the sous vide machine to 135°F, once the
water comes to temp then insert the bag of meat into the water.
Let the meat sit in the water for at least 1
hour and no longer than 4.
Before you pull the meat out of the water place
a pan over high heat with some butter or olive oil. Once you pull the meat from
the bath and remove it from the bag pat it dry then put it on the pan. Brown the
meat for about 2 min each side until a nice crust forms.
UPDATE: Someone in comments mentioned that I never mentioned the taste. It was great, very tender. It wasn't super buttery like I expected but I suspect that's due to the short cooking time. I plan to try it again with a longer water bath and a slightly fatter cut of meat.
