Ingredients

  • Prime rib: brings succulent tenderness and that classic flavor you want for a special meal Look for a roast with bright red color and good marbling for juiciness
  • Garlic: gives a rich mellow sweetness once roasted Choose fresh firm cloves for the most flavor
  • Fresh rosemary: delivers bright piney herbaceous notes Always use fresh rosemary for aroma and depth
  • Fresh thyme: layers in subtle earthiness adding to the savory roast flavor Use vibrant green sprigs with no wilting
  • Olive oil: ensures your herb paste spreads evenly over the meat and helps the crust brown beautifully Pick a robust extra virgin olive oil for best taste
  • Kosher salt: seasons deeply and produces that craveable umami crust Go for coarse flakes to help the flavors penetrate
  • Freshly ground black pepper: adds gentle heat and complexity Fresh cracked is far better than pre ground
  • Low sodium beef broth or red wine: creates a flavor packed au jus for serving Choose wine you would enjoy drinking or use homemade or high quality broth

Instructions

Let the Roast Come to Temperature:
Allow the prime rib to sit at room temperature for one hour before cooking This crucial step guarantees more even roasting and a juicier result
Make the Garlic and Herb Paste:
Combine peeled garlic, rosemary leaves, thyme leaves, olive oil, salt, and pepper in a food processor Pulse until you achieve a coarse aromatic paste You want everything to be well blended but still see flecks of herbs
Prep and Season the Roast:
Pat the prime rib dry with paper towels to help the paste stick well Spread the garlic and herb mixture thoroughly over every surface of the roast Press it in gently so nothing falls off during roasting
Set Up and Start Roasting:
Place the seasoned roast bone side down onto a rack set in your roasting pan The rack keeps the meat elevated for even cooking and better crust formation
Blast with High Heat:
Roast at 475°F for twenty five minutes This kick starts the browning process so the outside forms a savory crust that locks in juices
Lower the Heat and Slow Roast:
Reduce oven temperature to 325°F and continue to cook for one hour and forty five minutes to two hours Monitor closely and check temperature in the thickest part of the meat Aim for 125°F for medium rare perfection
Rest the Roast:
Take the roast out and loosely tent with foil Rest at least thirty minutes This makes the juices redistribute so every slice stays tender and moist
Make the Au Jus:
Set your roasting pan across two burners on the stove over medium heat Pour in beef broth or wine Scrape up every bit of caramelized flavor from the pan as you simmer for about five to ten minutes Strain the liquid for a delicious jus to drizzle over the meat
Carve and Serve:
Slice the roast across the grain into thick juicy slices Arrange on a platter and serve alongside your warm au jus
