Garlic Prime Rib

Ingredients

  • (10 pound) prime rib roast
  • cloves garlic, minced
  • tablespoons olive oil
  • teaspoons salt
  • teaspoons ground black pepper
  • teaspoons dried thyme

Instructions

  1. Step 1

    Place the prime rib roast, fatty side up, in a large roasting pan. In a small bowl, I mix together the minced garlic, olive oil, salt, pepper, and dried thyme into a fragrant paste. Then, I massage this mixture generously over the top and sides of the roast. Let the roast sit at room temperature for up to an hour—this helps it cook evenly. Meanwhile, preheat your oven to 500°F. Once the oven is scorching hot, slide the roast in and sear it for 20 minutes. This initial blast creates a beautiful crust. Without opening the door, reduce the heat to 325°F and continue roasting for another 60 to 75 minutes. I always use a meat thermometer to check for perfection: 145°F for a gorgeous medium rare. Remove the roast from the oven and let it rest on a cutting board for at least 10 minutes. This step is crucial

  2. Step 2

    it allows the juices to redistribute, ensuring every bite is moist and tender. Carve against the grain into thick slices and serve immediately.

Chef's Tip

I always take the prime rib out of the fridge about an hour before cooking so it loses its chill. Temperature matters: a cold roast won't cook evenly, and you might end up with a gray band around the edges. Let it come to room temp for a perfect, edge-to-edge blush of pink.

Storage Tips

Store leftover prime rib sliced in an airtight container in the fridge for up to 4 days. To reheat, gently warm slices in a skillet with a splash of beef broth over low heat to keep them juicy—avoid the microwave, which can turn this tender meat tough.

Variation Tips

For a different herb profile, swap dried thyme with rosemary or oregano. Serve alongside buttery roasted asparagus or a creamy cauliflower puree to keep it keto. A dollop of horseradish cream sauce adds a zesty kick.
