Description
Perfect Prime Rib Roast
Ingredients
1 (4-5 lb) bone-in prime rib roast
3 tbsp olive oil
4 garlic cloves, minced
1 tbsp fresh rosemary, finely chopped
1 tbsp fresh thyme, finely chopped
2 tsp kosher salt
2 tsp black pepper
1 tsp smoked paprika
Directions
Prepare the roast: Let the prime rib sit at room temperature for about 1 hour. Preheat oven to 450°F (230°C).
Make the rub: In a small bowl, mix olive oil, garlic, rosemary, thyme, salt, pepper, and smoked paprika. Rub this mixture generously all over the roast.
Sear in the oven: Place the roast bone-side down in a roasting pan. Roast at 450°F for 20 minutes to create a flavorful crust.
Lower the heat: Reduce oven temperature to 325°F (165°C) and cook until the internal temperature reaches 120°F (49°C) for medium-rare, about 1.5-2 hours. Use a meat thermometer to check.
Rest the meat: Remove from the oven and tent loosely with foil. Let it rest for 20-30 minutes; this helps retain the juices and finishes the cooking process.
Carve and serve: Slice against the grain and serve with your favorite sides!

Step-by-Step Guide
Follow these detailed instructions for a foolproof prime rib. First, ensure your roast is bone-in for the best flavor and juiciness. After letting it come to room temperature, preheat your oven. The high-heat sear at 450°F is non-negotiable for a perfect crust. When lowering the temperature to 325°F, place the roast bone-side down in the pan—the bones act as a natural rack. Do not open the oven door frequently. The most critical step is using a reliable meat thermometer. Insert it into the center of the meat, avoiding bone or fat. Once it hits 120°F, immediately remove it from the oven. The resting period is when the temperature will rise to the final 130-135°F for medium-rare.
Serving Suggestions
Carve your prime rib into thick slices for a stunning presentation. Traditional accompaniments include creamy horseradish sauce, au jus made from the pan drippings, and a robust red wine like Cabernet Sauvignon. For sides, consider classic Yorkshire puddings, roasted garlic mashed potatoes, and a bright, acidic salad or roasted asparagus to cut through the richness. This meal is perfect for holiday gatherings or a special Sunday dinner.
How-to Summary
To summarize the key process: Bring the roast to room temperature. Coat it with an herbed garlic rub. Sear for 20 minutes at 450°F. Roast at 325°F until the internal temperature is 120°F. Rest, tented with foil, for 20-30 minutes before carving against the grain.
Frequently Asked Questions
Can I use a boneless prime rib roast?
Yes, but cooking time may be slightly shorter. A bone-in roast provides more flavor and helps cook the meat more evenly.
What if I don’t have a meat thermometer?
It is highly recommended to use one for accuracy. Without it, you risk severe over or under-cooking. Estimate about 15-20 minutes per pound at 325°F after searing, but results will vary.
How do I make an au jus sauce?
After removing the roast, place the roasting pan on the stovetop. Add a cup of beef broth or red wine, scrape up the browned bits (fond), and simmer for 5 minutes. Strain and serve.
Can I prepare the roast ahead of time?
You can apply the herb rub up to 24 hours in advance and keep the roast covered in the refrigerator. Let it come to room temperature before roasting as directed.
What’s the best way to reheat leftovers?
To prevent drying, reheat slices gently in a 250°F oven with a bit of au jus or broth until just warmed through, or enjoy them at room temperature.
Common Mistakes to Avoid
- Skipping the Rest: Cutting into the roast immediately will cause the precious juices to spill out, leaving you with dry meat.
- Not Using a Thermometer: Guessing doneness is the leading cause of overcooked, expensive prime rib.
- Roasting Straight from the Fridge: A cold center will lead to uneven cooking.
- Overcrowding the Pan: Ensure your roasting pan is large enough so heat can circulate around the meat.
- Using Dried Herbs Instead of Fresh: For the rub, fresh rosemary and thyme provide a vastly superior flavor.
