Easy Prime Rib Au Jus
An elegant, savory and delicious prime rib that is easy to prepare and makes any meal a special one.
- One 6 - 7 lb. bone in prime rib roast
- Kosher Salt
- Coarsely ground black pepper
- 1 stick unsalted butter
- 4 cups beef stock
- 2 cups red wine
- 1 sprig fresh rosemary with leaves removed from stem and chopped
TO MAKE THE ROAST
Preheat oven to 450 degrees F.
Season the roast liberally with salt and pepper.
Set the roast on a rack inside a roasting pan and roast for 30 minutes. Do not cover the roast.
Turn the oven temperature down to 350 degrees F and continue roasting until an instant thermometer inserted into the thickest part of the meat registers 130 degrees F, for medium rare, about 1 1/2 hours.
Transfer the meat to a platter and tent with tin foil to keep warm.
Do not slice the roast at this point. Allow the roast to rest for at least 10 minutes.
TO MAKE THE AU JUS
Place the roasting pan across two burners on the stove and turn them to high.
Add the entire stick of butter to the pan and use a wooden spoon to scrape the bottom of the pan to loosen the cooked-on bits.
Add the beef stock and red wine and cook until the liquid is reduced by half, about 20 minutes.
Whisk in the rosemary and season with salt and pepper.
TO REHEAT LEFTOVERS:
Preheat oven to 300 degrees F.
Place desired amount of prime rib into a pan, add a few tablespoons of beef broth and cover tightly with tin foil.
Heat until the meat reaches 160 degrees, when measured with an instant thermometer.
