Ingredients You’ll Need
For the Prime Rib:
- 1 (5–6 lb) bone-in prime rib roast
- 3 tbsp olive oil
- 6 cloves garlic, minced
- 2 tbsp fresh rosemary, finely chopped
- 1 tbsp fresh thyme leaves
- 1 tbsp coarse kosher salt
- 1 tsp freshly ground black pepper
- 1 tsp onion powder
- 1 tsp smoked paprika (optional, for color)
For the Herb Butter Finish:
- 3 tbsp softened butter
- 1 tsp garlic powder
- ½ tsp salt
- ½ tsp black pepper
- 1 tsp chopped parsley
Step-by-Step Instructions
1. Bring the Meat to Room Temperature
Remove your prime rib from the refrigerator about 2 hours before cooking. This allows the roast to cook evenly and helps achieve that perfect pink center.
2. Prepare the Garlic Herb Rub
In a small bowl, mix olive oil, minced garlic, rosemary, thyme, salt, pepper, onion powder, and smoked paprika. Stir until a fragrant paste forms.

3. Season the Roast
Pat the prime rib dry with paper towels to remove excess moisture. Rub the garlic-herb paste all over the roast every side should be coated generously. Place it on a roasting rack inside a large pan, bone side down.
4. Sear at High Heat
Preheat your oven to 500°F (260°C). Roast the meat for 15 minutes to develop a rich, golden crust.
5. Lower the Heat & Slow Roast
Reduce oven temperature to 325°F (165°C). Continue roasting for about 13–15 minutes per pound, or until internal temperature reaches:
- 120°F (49°C) for rare
- 130°F (54°C) for medium-rare
- 140°F (60°C) for medium
Use a meat thermometer for accuracy it’s your best friend here!

6. Rest Before Slicing
Remove the roast from the oven, tent it loosely with foil, and let it rest for at least 20–30 minutes. This allows the juices to redistribute, keeping your meat moist and tender.
7. Add the Herb Butter Finish
While the roast rests, mix softened butter with garlic powder, salt, pepper, and parsley. Spread it lightly over the top before slicing it melts beautifully into the crust, adding extra flavor.
8. Slice & Serve
Use a sharp carving knife to slice between the bones or into thick, juicy slices. Serve with au jus, mashed potatoes, or roasted vegetables for a complete, restaurant-quality meal.
Serving Suggestions
Your Garlic Herb Prime Rib Roast deserves the spotlight, but the right sides make it shine even more. Serve it with:
- Creamy mashed potatoes or horseradish sauce for balance
- Roasted carrots and Brussels sprouts for color and texture
- Yorkshire pudding for a classic touch
Pair with a full-bodied red wine like Cabernet Sauvignon or Merlot, and finish the meal with something light perhaps a slice of lemon tart or a fruit salad.
