PRIME RIB ROAST

step-by-step guide

What Cut of Meat to Buy?

This beautiful piece of meat at the grocery store may not be called “Prime Rib.” Most likely, it will be called Beef Bone-in Rib Roast or a Standing Rib Roast.

1. Bring to Temp

Remove covered roast from the refrigerator and let it rest for 30 minutes prior to roasting to bring to room temperature.

2. Prep Your Pan

Add 1 large onion to the bottom of the roasting pan along with whole head of garlic, 8 sprigs of thyme, and 2 sprigs of rosemary. Set aside.

3. Pre-Heat

Pat Prime Rib Roast dry with a paper towel and preheat the oven to 225 degrees F.

4. Make Herb Butter

In a small bowl, add garlic clove, salt, black pepper, rosemary, thyme, and oregano. Using a spoon, mix. Remove 1 tbsp of the mixture and add it to another small bowl with 1/3 cup unsalted softened butter. Mix, then set aside. To the bowl with the remaining herb mixture, add 2 tbsp of olive oil &  mix together to form a paste.

5. Rub Herb Paste

Rub garlic herb paste all over the Prime Rib using your hands and place bone side down on a rack in a roasting pan.

6. Start Roasting

Roast, uncovered, for 3-4 hours. When the center of the roast reaches 120° F (for medium rare), remove from oven and tent with tin foil for 20 minutes. Turn oven up to 500°F.

7. Add Garlic Butter

After 20 minutes, remove the tinfoil tent & rub the garlic herb butter on the top and sides of the roast. Place roast back in oven, uncovered, for 15-20 minutes. You want the outside of the roast to be nicely browned.

8. Rest & Serve

Remove the prime rib roast from the oven and place on a cutting board. Tent with tinfoil and let rest for 20 minutes. Slice and serve with horseradish sauce or au jus.
