Slow Roasted Prime Rib
Cooking prime rib low and slow locks in all the juices for the best flavor and tenderness. You'll notice hardly any juice drips from the roast when you perfectly cook it in the oven - that means all that juicy goodness stays in the beef!
This results in a prime rib roast that is more tender and juicy than any other method. After roasting, I sear it for a beautiful, crisp brown crust.
This recipe was so easy to make and was the best prime rib I have ever tasted thanks for the inspiration!Charley on Pinterest

Slow Cooked Prime Rib Temps
When cooking prime rib, always use a meat thermometer to get an accurate read on the temperature of your roast. Follow our prime rib temperature chart for the best results. I love a good medium rare prime rib.
|Rare beef temp
|125°F - bright red in the middle
|135°F - warm red in the middle with slight pink around the edges
|145°F - warm pink throughout
|150°F - slightly pink at the center

What is slow-cooked prime rib?
Slow-cooked prime rib is a prime rib that has been cooked slowly and at a low temperature in the oven to maximize tenderness and lock in the flavor from the juices of the roast. The ideal oven temperature for slow-cooked prime rib is 200°F (or 93°C) at approximately 40 minutes per pound.
How far ahead of time do I need to season prime rib?
Salt your roast with kosher or sea salt the day before you cook it, and refrigerate it overnight, uncovered. For best results, do not salt it more than one day ahead of time, and only add the pepper when ready to roast.
Slow Cooked Prime Rib FAQs
A roasting pan with a rack is best for cooking prime rib. This allows air to circulate all around the prime rib roast while the pan beneath collects the drippings.
A raw roast should be kept no more than 3 to 5 days in the refrigerator before roasting.
Bring your roast to room temperature before roasting by leaving it out for approximately 2 hours. Prime rib should be at room temperature before cooking to ensure an even temperature throughout the roast.
How Much Prime Rib Per Person
You will need ½ pound of prime rib per person when the roast is part of a holiday spread, or ¾ pound per person if serving it as the main course. Here is a quick reference guide for how much prime rib per person you will need according to your number of guests:
|Number of Guests
|Prime Rib as Main Course (¾ lb. serving)
|Prime Rib as part of Holiday Spread
(½ lb. serving)
How to Store and Reheat
Storing Prime Rib:
- Let it Cool: Allow the prime rib to cool at room temperature for about 2 hours after cooking. This helps retain its juices.
- Wrap it Properly: Once cooled, wrap the prime rib tightly in plastic wrap or aluminum foil. Ensure there are no air pockets, as exposure to air can cause the meat to dry out.
- Use an Airtight Container: Alternatively, you can store it in an airtight container. Make sure it fits the meat snugly to minimize air exposure.
- Refrigerate: Place the wrapped or container-sealed prime rib in the refrigerator. It's best to consume it within 3-4 days to maintain quality.
Reheating Prime Rib:
- Preheat the Oven: Preheat your oven to a low temperature, around 250°F (120°C). This low heat prevents overcooking and helps retain moisture.
- Add Moisture: Place a pan or oven-safe dish with a small amount of beef broth, au jus, or water in the bottom of the oven. This creates a humid environment, reducing the risk of drying out the meat.
- Reheat Slowly: Place the unwrapped prime rib on a wire rack or in an oven-safe dish and set it in the oven. Reheat for approximately 10-15 minutes per pound or until the internal temperature reaches your desired level of warmth (usually around 130°F or 54°C for medium-rare).
- Rest Before Slicing: Allow the reheated prime rib to rest for a few minutes before slicing it. This redistributes the juices, ensuring a juicy and flavorful result.
- Serve: Slice and serve the reheated prime rib with your favorite side dishes and sauces.
Avoid using a microwave for reheating as it tends to dry the meat. The low and slow oven method is the best way to maintain the prime rib's quality and flavor when reheating.
