  • Set sous vide machine to 132-degrees (for medium-rare) and attach it to a large pot filled with water. Place sealed roast in the water bath. Clip the bag to the side of the pot to ensure it stays submerged. Sous vide for 6 to 10 hours.

  • Remove the beef from the bag once the cooking time is up. Reserve the cooking liquid! Pat the roast dry. Preheat oven to 550°F. In the meantime, in a small bowl, combine butter with garlic powder, rosemary, thyme, and pepper. Coat the top and sides of the roast with the garlic herb butter.

  • Place in a roasting pan with a rack. Roast the prime rib for 8-10 minutes, until the crust is golden (keep a close eye on it!).

  • Remove from the oven and let rest. While the roast rests, make the au jus. In a large skillet, bring the sous vide cooking liquid and beef broth to a boil.

  • When preparing the sous vide, be sure to find the correct sized container for your water bath. I suggest using a large pot or Dutch oven.The bag containing the prime rib must be completely submerged in water.
  • Use a roasting pan with a rack so air can circulate around the whole roast.
  • Let your roast rest! Once it's done roasting, tent your beef with foil and let it sit for 15 minutes before carving.
  • Slice against the grain. This is vital! The grain refers to the lines running through the beef. Slice against the grain for the most tender sliced prime rib.
  • To ensure the sous vide bag containing the meat is completely covered in the water, use a clip or small weight to keep submerged.
  • Note: Nutritional value is for prime rib only.
