Prime Rib with Porcini Mushroom Crust

The deep, expressive notes of our Cabernet Sauvignon pair wonderfully with the herbs and cracked pepper flavors in this popular recipe.


  • 10 lbs prime rib roast
  • 2 Tbsp Trefethen extra virgin olive oil
  • Trefethen Porcini Mushroom Spice Blend packet or individual spices as listed below
  • 2 Tbsp dried garlic powder
  • 2 Tbsp dried onion powder
  • 2 Tbsp fresh thyme, chopped
  • 2 Tbsp dried Porcini mushroom powder
  • 2 Tbsp salt
  • 2 Tbsp fresh black pepper


  • 1Place the roast in a roasting pan with the fatty side up. Rub the rib with the oil to create a nice layer all around the meat. In a small bowl, mix together all other dried ingredients. Spread the mixture over the roast, concentrating most of the crust on the top fatty side. Let the roast sit out until it is at room temperature, about an hour.
  • 2Preheat the oven to 500F. Bake the roast for about 20 minutes in the preheated oven to brown the crust. Careful not to burn the spices. Reduce the temperature to 325F and continue roasting for an additional hour or until the internal temperature of the roast is 135F for a lovely medium-rare.
  • 3Allow the roast to rest for 10-15 minutes before carving so the meat can retain its juices. Slice into thick steaks and enjoy!
