Recipe Instructions

Step 1

Gather all ingredients.

Step 2

Serve and enjoy!

Step 3

The day before you plan to serve the prime rib, remove roast from the package and dry thoroughly with paper towels. Set roast on a baking sheet, and place in refrigerator overnight. Remove from refrigerator 1 hour before cooking to allow beef to reach room temperature.

Step 4

Rub prime rib roast all over with horseradish and Dijon mustard. Mix kosher salt, black pepper, thyme, and garlic powder together in small bowl; sprinkle over roast.

Step 5

Preheat the oven to 450 degrees F (230 degrees C). Place celery, carrot, and onion into the bottom of a roasting pan; place roast on top.

Step 6

Roast in the preheated oven for 30 minutes. Reduce oven temperature to 350 degrees F (175 degrees C), and roast until beef is browned and an instant-read meat thermometer inserted into the thickest part of the roast reads 130 degrees F (54 degrees C) for medium-rare.

Step 7

Remove from oven, transfer roast to a platter, and cover with a tent of aluminum foil. Allow to rest for 30 minutes. The temperature of the beef will rise about 10 degrees during resting time.

Step 8

To make au jus sauce: Skim excess fat from pan drippings in the roasting pan. Place the pan over medium heat and stir in beef base and 1 ½ cups of water. Bring to a boil while scraping and dissolving any browned bits from the bottom of the pan.

Step 9

Strain out and discard vegetables. Combine cornstarch and 1 teaspoon of water in a small bowl until smooth; whisk into sauce.

Step 10

Allow sauce to thicken slightly; pour into a gravy boat.
