I have never cooked a prime rib until today. Mac did some research online as to cooking method. The way I cooked it is in the instructions. I liked this method because your oven is not on for 2 or 3 hours. A lot of people serve prime rib with a horseradish sauce. Since we liked blue cheese, I decided to make this garlic blue cheese dressing
Prime Rib with Garlic Blue Cheese Dressing
4 to 5 lb. Bone-in prime rib roast
6 large garlic cloves
½ c. fresh basil leaves
¼ c. fresh rosemary leaves
2 tsp. Kosher salt
2 tsp. Freshly ground black pepper
3 Tbsp. Dijon mustard
3 Tbsp. Butter
3 Tbsp. Olive oil
Let roast stand at room temperature for 2 hours. Preheat oven to 500 degrees F.
In food processor, finely mince garlic, rosemary, basil, salt and pepper. Add mustard, butter and oil, processing to form a paste. Smear the paste over the top and sides of the roast.
Cook the roast in a pan, bone side down, for 5 minutes per pound of roast. Turn off oven without opening it. Let roast set in oven for 2 hours. You may want to check the temperature of your oven to make sure it stays above 200 degrees with a thermometer. If it drops below 200 within the 2 hours, turn the oven back on at 250 degrees for the remainder of the 2 hours. You want the internal temperature to be 130 to 140 for medium rare.
FOR DRESSING: Place ¾ cup heavy cream and 1 medium garlic, minced, in a medium saucepan. Bring to a boil over medium-high heat, then lower heat and simmer until the cream coast the back of a spoon, 5 to 10 minutes. Remove the pan from the heat and stir in 6 oz. of crumbled blue cheese. Season to taste with freshly ground black pepper.
Carve the meat into slices. Serve with the dressing.
