Step-by-Step Instructions
- Preheat your oven to 450°F (232°C).
- In a small bowl, mix together olive oil, salt, pepper, garlic powder, rosemary, thyme, and minced garlic to form a seasoning paste.
- Generously rub the seasoning mixture all over the prime rib roast, ensuring an even coating.
- Place the seasoned roast in a roasting pan, bone side down, for the best stabilization during cooking.
- Roast in the preheated oven for 20 minutes to develop the initial crust.
- Lower the oven temperature to 325°F (163°C) and continue to roast until the internal temperature reaches your desired doneness, which usually takes about 1.5 to 2 hours for medium-rare.
- Once finished, remove the roast from the oven and let it rest for at least 20 minutes before carving to retain juiciness.
Best Ways to Enjoy It
The perfect prime rib deserves to shine, so consider serving it alongside creamy mashed potatoes, roasted vegetables, or a fresh green salad. A rich red wine or a classic port sauce pairs wonderfully, enhancing the roast’s flavors. Additionally, you can offer some horseradish sauce on the side for an extra layer of zest that balances the richness of the meat.
Keeping Leftovers Fresh
Storing your prime rib properly will make sure you enjoy every last bite. Allow the meat to cool completely before wrapping it tightly in plastic wrap or placing it in an airtight container. It can be stored in the refrigerator for up to 3-4 days. You can also freeze it for longer storage—just make sure to carve it into portions first, so you can easily reheat what you want when the craving strikes!
Practical Cooking Tips
- Use a meat thermometer for precision! Checking the internal temperature ensures that you reach your desired doneness without second-guessing.
- Let your roast come to room temperature before cooking; this helps it cook evenly.
- Don’t rush the resting phase after roasting. This crucial step allows the juices to redistribute throughout the meat, ensuring every bite is juicy.
Creative Twists
Feel free to experiment with different flavor profiles! For a spice kick, add a bit of cayenne or smoked paprika to your seasoning blend. You could also consider stuffing the roast with herbs or veggies like spinach and feta cheese for a unique twist.

How long does it take to cook a prime rib roast?
Generally, you can expect to roast it for about 1.5 to 2 hours at 325°F (163°C) for medium-rare. The cooking time will depend on the weight of the roast and your desired doneness, so use a meat thermometer for the best results.
Can I use a different cut of meat?
While the prime rib roast is a classic choice for its tenderness and flavor, you could use a ribeye or a chuck roast, although the results may vary in richness and tenderness.
What’s the safe internal temperature for prime rib?
For medium-rare, aim for an internal temperature of 135°F (57°C). Keep in mind that the meat will continue to cook slightly as it rests, so it’s safe to remove it from the oven a little earlier to reach your desired doneness.
