Ingredients
Scale
- 1 9-10 pound bone-in prime rib roast (also called standing rib roast)
- 4 garlic cloves, peeled and cut into slivers
- 1/2 ounce dried porcini mushrooms
- 1 T kosher salt
- 1 t freshly ground black pepper
Instructions
- Bring the roast to room temperature by taking the rib roast out of the fridge 1-2 hours before you prepare it.
- Heat the oven to 450 degrees. With a paring knife, poke holes every few inches throughout the roast. Push a garlic sliver into each hole.
- Put dried mushrooms in a food processor or blender and whirl until mushrooms are ground into a fine powder. Mix mushroom powder, salt and pepper together. Rub the entire surface of the roast with the mixture.
- Place roast in a roasting rack set inside of a roasting pan. Roast at 450 degrees for 20 minutes. Turn heat down to 350 degrees and roast until a thermometer stuck in the middle of the roast reads 120 degrees, 1 1/2 to 2 more hours.
- Put the roast on a platter while it rests so you can collect its juices. After 30 minutes, the internal temperature of the roast should should be about 140 degrees, or medium rare.
- Transfer to a carving board. Cut the strings from your roast and slice.
