How to Sous Vide Prime Rib Roast

Sous vide is the French word for ‘under vacuum’, but the technique is also used in the United States to refer to food that has been cooked in a water bath at a low temperature for long periods.

In sous vide cooking, the cooking temperatures are kept between 145°F and 165°F, and cook times are often 4 or more hours.

  • When it’s sizzling hot, preheat a large cast-iron skillet to medium-high heat.

Note 1: 

A bone-in roast is easier to vacuum seal than a boneless prime rib roast. You just need to use a double bag to make sure the bones don’t puncture the bag.

Note 2:

The Prime Rib Rub containers are the same as Kosher Salt, but the roast will soak up some of the salt when cooking in the water bath.

If you want to control the amount of salt, we recommend just salt-less spices. The salt in the Au jus is very healthy.

Note 3: 

The timer can be set for a minimum of 8 hours, up to 10 hours, and get the same results.

It’s important to make sure the roast is ready when you’re ready to eat. Add two hours to the cooking time if you are starting with a frozen prime rib roast.
