Quick Facts

• Yield: Serves 6–8
• Prep Time: 20 minutes
• Cook Time: 1 hour 30 minutes
• Total Time: 1 hour 50 minutes (including resting)

Ingredients

For the Main Dish:

• 1 (4–5 pound) prime rib roast, bone-in
• 6 cloves garlic, minced
• 2 tbsp fresh rosemary, finely chopped
• 2 tbsp fresh thyme leaves
• 1 tbsp kosher salt
• 2 tsp freshly ground black pepper
• 3 tbsp olive oil

For the Sauce / Garnish (optional):

• 1 cup beef broth
• 1/2 cup red wine (optional)
• 2 tbsp unsalted butter
• Fresh parsley, chopped (for garnish)

How I Make It

Step 1:

First, take your prime rib out of the fridge and pat it dry with paper towels. This helps the herb crust stick and forms that golden, crispy exterior we’re after. Then, combine minced garlic, rosemary, thyme, salt, pepper, and olive oil in a small bowl to make a fragrant herb paste.

Step 2:

Rub this flavorful mixture all over the roast, making sure to massage it into every nook and cranny—don’t be shy! Let the roast sit at room temperature for about 30 minutes while you preheat your oven to 450°F. This helps it cook evenly.

Step 3:

Place the roast on a rack in a roasting pan, fat side up, and pop it in the oven. Roast at 450°F for 15 minutes to develop a nice sear. Then, lower the heat to 325°F and continue cooking for about 1 hour to 1 hour 15 minutes, or until the internal temperature hits 130°F for medium-rare (use a meat thermometer here — absolute game changer).

Step 4:

Once it reaches the perfect temp, remove it from the oven and tent it loosely with foil. Let it rest for at least 20 minutes—this step is key for juicy slices, as it allows the juices to redistribute.

Step 5 (Optional Sauce):

While the roast rests, pour the drippings from the pan into a small saucepan. Add beef broth and red wine, and simmer over medium heat until slightly reduced and flavorful. Swirl in a couple tablespoons of butter for richness, then strain if you want a smooth sauce.

Step 6:

Slice your prime rib rib-eye thick or thin, depending on your crowd’s preference, arrange on a platter, drizzle with the sauce, and sprinkle with fresh parsley. Get ready for that melt-in-your-mouth moment.

Variations & Tips

• Swap fresh herbs for dried if needed—use about 1 tsp each since dried are more concentrated.
• Let the roast sit uncovered in the fridge overnight after rubbing with herbs for an even crispier crust.
• Use a digital instant-read thermometer to avoid overcooking—130°F is perfect medium-rare.
• Try adding a teaspoon of Dijon mustard to the herb rub for a subtle tang.
• If you have leftover roast, slice thin for amazing sandwiches with horseradish sauce.
• Resting the meat is non-negotiable—it locks in juices and improves tenderness.

How I Like to Serve It

We love pairing this prime rib with creamy mashed potatoes and roasted vegetables for a classic Sunday dinner. It’s also a showstopper for holiday feasts like Christmas or Easter, when everyone’s gathered around the table. For a simpler weeknight treat, slice it thin and serve with a fresh arugula salad and crusty bread to soak up all the pan juices.

Notes

• Store leftovers wrapped tightly in foil or an airtight container for up to 3 days.
• Reheat gently in the oven at low temperature or slice cold for sandwiches to keep it tender.

Closing: This Garlic Herb Prime Rib Roast is one of those recipes that turns any meal into a celebration — juicy, flavorful, and always a crowd-pleaser in my kitchen!
