 Cooking Time & Yield

• Prep Time: 15 minutes
• Resting Time (before cooking): 2 hours
• Cooking Time: 1½–2 hours (depending on size)
• Resting Time (after cooking): 20–30 minutes
• Total Time: ~4 hours
• Servings: 6–8 people

 Ingredients

For the Prime Rib

• 1 prime rib roast (4–6 lb / 1.8–2.7 kg)
• 2 tablespoons olive oil
• 2 tablespoons kosher salt
• 1 tablespoon freshly ground black pepper
• 1 tablespoon garlic powder
• 1 tablespoon fresh rosemary, finely chopped
• 1 tablespoon fresh thyme, finely chopped
• 4 cloves garlic, minced

 Step-by-Step Instructions

1 Bring the Prime Rib to Room Temperature

Remove the prime rib roast from the refrigerator at least 2 hours before cooking.

This step is crucial. Allowing the meat to come to room temperature ensures:

• Even cooking from edge to center
• A perfectly pink interior
• No cold center after roasting

Place the roast on a tray or plate and leave it uncovered.

2 Preheat the Oven

Preheat your oven to 450°F (230°C).

This high temperature will help create a deep, flavorful crust during the initial sear.

3 Season the Roast Generously

Pat the prime rib dry with paper towels—this helps the seasoning stick and promotes browning.

Rub the entire roast with olive oil.

In a small bowl, combine:

• Kosher salt
• Black pepper
• Garlic powder
• Fresh rosemary
• Fresh thyme
• Minced garlic

Massage the seasoning mixture evenly over all sides of the roast, including the ends. Don’t rush this step—proper seasoning is key to bold flavor.

4 High-Heat Oven Sear

Place the prime rib fat-side up on a rack inside a roasting pan.
The rack allows heat to circulate and prevents the meat from sitting in its own juices.

Roast at 450°F (230°C) for 20 minutes.

This step creates a beautiful brown crust and seals in moisture.

5 Slow Roast to Medium-Rare

After 20 minutes, do not remove the roast.
Reduce the oven temperature to 325°F (165°C).

Continue roasting for approximately 15 minutes per pound, or until a meat thermometer inserted into the thickest part reads:

• 125–130°F (52–54°C) → Medium-rare
• (Temperature will rise during resting)

Important: Always rely on a thermometer, not just time.

6 Rest the Meat (Very Important)

Remove the prime rib from the oven and place it on a cutting board.

Tent loosely with aluminum foil and let it rest for 20–30 minutes.

Why resting matters:

• Juices redistribute throughout the meat
• Texture becomes tender and juicy
• Internal temperature rises to the perfect medium-rare (130–135°F)

Do not skip this step.

7 Slice and Serve

Using a sharp knife, slice the prime rib against the grain into thick or thin slices, depending on preference.

You should see:

• A crisp, seasoned crust
• A warm, juicy, pink center
• Minimal juice loss on the cutting board

Serve immediately.

 Serving Suggestions

Prime rib pairs beautifully with:

• Creamy mashed potatoes
• Roasted vegetables
• Yorkshire pudding
• Horseradish sauce
• Au jus made from pan drippings

Pro Tips for Perfect Prime Rib

• Bone-in vs boneless: Bone-in adds flavor and insulation; boneless cooks slightly faster
• Use a meat thermometer: Essential for accuracy
• Don’t over-season with salt early: Salt right before cooking for best texture
• No need to baste: Prime rib is naturally rich and self-basting
