Prime Rib Au Jus
A four step method for cooking the perfect prime rib or standing rib roast.
Ingredients
- 1 Each Prime Rib (2 lbs or larger)
- 1 Cup Onion Trimming
- 2 Cups Beef Stock Or Broth
- 1 Tbsp Dry Red Wine
- 1 Tbsp Tomato Ketchup
- 1 Tbsp Corn Starch
- 2-3 Tbsp Salt
- Ground Black Pepper To Taste
Instructions
Mis En Place
- Two to 24 hours prior to cooking, cover the top of the roast with salt and return to refrigerator. Salt will remove excess moisture and ensure a crisp crust.
- Prior to cooking allow roast to come to room temperature. It takes about 15 minutes per pound.
Preparation - The Roast
- Preheat oven to 450 degrees Fahrenheit.
- Season roast with salt and pepper and place in a low sided roasting pan atop of a bed of the sliced onion.
- Sear roast by placing it in the 450 degree oven for 15 minutes.
- Reduce heat to 325 degrees and roast ribs. Cooking time in minutes will be equal to the weight of the roast times 15. So a 2 pound roast would need 30 minutes of roasting. A 4 pound roast would need 1 hour. Use a meat thermometer and remove roast when internal temp reaches 112 to 120 degrees for rare to medium rare.
- Allow roast to rest on counter for 30 minutes while Jus Lei’ is prepared. Roast temperature will rise while resting.
Preparation - The Jus Lei
- Mix together one tablespoon of the stock with the red wine and ketchup and then mix in the cornstarch.
- Use beef stock to deglaze the font in the bottom of the roasting pan and taste and adjust salt & pepper as needed.
- Add the cornstarch mixture to the stock and deglazed font mixture & bring to a boil. Jus Lei’ is a light sauce but if you prefer a thicker version add additional cornstarch that has been dissolved in water. Strain the Jus Lei’ into a sauce pan and keep warm over low heat.
- Slice prime rib and serve with a small amount of Jus Lei’.
