Sous Vide Prime Rib

Step 1

Liberally season the prime rib roast with kosher salt and place in the refrigerator for at least one hour, up to 12 hours.

Step 2

Set the sous vide machine to 132 degrees F for medium rare. (*Note 3)

Step 3

Place the prime rib roast in a heavy-duty vacuum bag and vacuum seal.

Step 4

Transfer the sealed bag to the water bath and set the timer to 8-12 hours. (*Note 3)

Step 5

Right before removing the prime rib roast from the water bath, make the Prime Rib Au Jus. Keep warm on the stove until ready to serve. (*Note 4)

Step 6

Whisk together the ingredients for the Prime Rib Rub and set aside.

Step 7

Pre-heat a large cast iron skillet over medium-high heat until it's scorching hot (it will start to smoke a little).

Step 8

While the cast iron skillet is pre-heating, remove the prime rib from the bag and reserve the cooking liquid to use in the Au Jus in place of the beef broth, if desired. Pat the prime rib dry with a paper towel.

Step 9

Cover the roast with 1-2 Tbsp oil followed by the prime rib rub.

Step 10

Sear the roast for 1 minute per side, including the ends (for a total of six sides).

Step 11

Let rest for 15 minutes. Carve into 1/2"-1" slices (Personal preference) and serve with the au jus.
