A Prime Rib Roast (also known as a Standing Rib Roast or Ribeye Roast) is the king of holiday dinners. Nothing is more impressive than presenting a beautifully browned roast with a perfectly pink interior. This recipe demystifies the process, utilizing the tested and perfected high-sear, low-roast method. This simple technique guarantees a crackling herb crusted exterior and a moist, evenly cooked interior from edge to edge—the secret to mastering the perfect roast every time.
The secret starts with a rich herb butter rub, blending fresh rosemary, thyme, garlic, and coarse salt, which builds an aromatic crust during the initial high-temperature sear. Following that sear with a long, slow roast gently raises the meat’s temperature, ensuring that desirable edge-to-edge medium-rare finish. If you’ve ever wondered how to cook prime rib like a professional chef, this step-by-step guide is your definitive answer.

Ingredients
- 1 (10 pound) Bone-In Prime Rib Roast (Standing Rib Roast)
- 1 cup Unsalted Butter, softened (do not melt!)
- 2 Tbsp Fresh Rosemary, chopped
- 2 Tbsp Fresh Thyme, chopped
- 2 Tbsp Fresh Italian Parsley, chopped
- 8 cloves Garlic, crushed (or finely minced)
- 2 tsp Coarse Sea Salt
- 2 tsp Ground Black Pepper
- 1–2 cups Water or Beef Broth (for the roasting pan)
Instructions (Step-by-Step)
- Bring to Room Temperature (Crucial): Remove the Prime Rib Roast from the refrigerator and place it on a cutting board at room temperature for at least one to two hours before cooking. This allows the meat to cook more evenly.
- Prep Oven and Pan: Preheat your oven to a blazing 450°F (232°C). Pour 1–2 cups of water or beef broth into the bottom of your roasting pan (this prevents drippings from burning and provides moisture for gravy later).
- Make the Herb Rub: In a small bowl, combine the softened butter, rosemary, thyme, parsley, crushed garlic, sea salt, and black pepper until a thick paste forms.
- Rub and Sear: Rub a light layer of the herb butter onto the bottom and sides of the roast. Place the standing rib roast, bone side down (this acts as a natural rack), in the roasting pan. Slather the remaining thick layer of the herb butter mixture evenly over the top of the roast.
- The High Sear: Place the roast in the preheated 450°F oven for 20 minutes. This creates the initial, crucial, flavorful crust.
- The Low Roast: After 20 minutes, turn the oven temperature down to 250°F (121°C). Continue roasting for approximately 12–15 minutes per pound of meat. Use a meat thermometer inserted into the thickest part of the meat (avoiding bone and fat) to check the internal temperature.
- Rest (Non-Negotiable): Remove the roast from the oven when it reaches 122°F for medium-rare (see chart in tips). Loosely tent the roast with aluminum foil and allow it to rest for at least 30 minutes before slicing.
- Slice and Serve: Slice the prime rib against the grain into ½- to 1-inch slices.
Internal Temperature Guide (Remove from Oven at This Temp)
| Doneness | Remove at | Final Temp (After Rest) |
| Rare | 120°F (49°C) | 125°F (52°C) |
| Medium-Rare (Recommended) | 122°F (50°C) | 130–135°F (54–57°C) |
| Medium | 130°F (54°C) | 135–140°F (57–60°C) |
Storage and Reheating
Store leftover prime rib slices in an airtight container in the refrigerator for up to 5 days.
Reheating (Recommended): Preheat your oven to 300°F (150°C). Place slices on a wire rack over a baking sheet. Cover loosely with foil and bake for 15 minutes. Remove foil and continue cooking for 5 more minutes. This method gently reheats the beef without drying it out.
Expert Tips
- Use a Meat Thermometer: This is the single most important tool for cooking a Prime Rib Roast. Do not rely solely on cooking time per pound; use a probe thermometer inserted into the center of the roast to monitor the exact temperature.
- The Magic of Resting: The 30-minute rest is absolutely critical. During this time, the internal temperature continues to rise (carry-over cooking), and the juices, which have been pushed to the center, redistribute throughout the meat, resulting in a juicy, tender slice. Cutting it early will allow all the juices to run out.
- Frenched Bones: Ask your butcher to “French” the bones (removing the excess fat and meat around them) for a beautiful presentation. You can also ask them to cut the bones away and tie them back on; this makes carving much easier later.
- Saving the Drippings: The fat and broth mixture in the bottom of the pan is liquid gold. Skim the fat and use the remaining liquid as the base for a rich au jus or a quick gravy.
Variations
- Boneless Roast: This recipe works for a boneless prime rib as well. Place it on a wire rack inside the roasting pan to allow air circulation beneath it. Cook time per pound remains the same.
- Different Herbs: Swap the herb blend! Use fresh sage and oregano for a different flavor profile, or add a pinch of dried red pepper flakes to the rub for a hint of heat.
- Garlic Cloves Inserted: For an even deeper garlic flavor, use a small, sharp knife to poke small slits into the roast before applying the rub, and insert half a fresh garlic clove into each slit.
Serving Suggestions
A magnificent herb crusted prime rib deserves equally impressive side dishes:
- Potatoes: Creamy Horseradish Mashed Potatoes, Crispy Smashed Potatoes, or classic Roasted Root Vegetables.
- Vegetables: Simple sides that don’t compete with the meat, like roasted asparagus, Bacon Maple Brussels Sprouts, or Green Beans with Garlic.
- Sauce: Serve with a side of creamy Horseradish Sauce (a must!) and the simple Au Jus made from the pan drippings.
Frequently Asked Questions
Q: Can I use a boneless prime rib for this high-sear, low-roast method?
A: Yes, this method works for a boneless prime rib (ribeye roast) as well. You will place the roast directly on a wire rack inside the roasting pan since you won’t have the bones to act as a natural rack. The cook time per pound remains the same.
Q: Why do I need to take the meat out of the oven at 122°F for medium-rare?
A: This is due to carry-over cooking. While the meat rests for 30 minutes, the internal temperature will continue to rise by 5–10 degrees (to the final 130–135°F). Removing it early prevents the entire roast from overcooking while guaranteeing that signature, perfect pink center.
Q: What is the best way to slice the prime rib?
A: Always slice against the grain (perpendicular to the lines of muscle fiber). If your butcher tied the bones back on, untie them and slice the meat away from the bones first. Then, slice the boneless roast into uniform slices using a long, sharp knife.
Q: Can I make a smaller, 4–6 pound prime rib with this recipe?
A: Yes. Halve all the rub ingredients. Sear the roast at 450°F for only 10–12 minutes (instead of 20 minutes for a larger roast), then drop the temperature to 250°F and continue cooking for 12–15 minutes per pound, always relying on the internal temperature chart.

- 2 tsp Coarse Sea Salt
- 2 tsp Ground Black Pepper
