Slow-Roasted Prime Rib

Cooking prime rib low and slow locks in all the juices for the best flavor and tenderness. You'll notice there's hardly any juice that 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 it's done 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!

Bone-in Prime Rib Recipe Ingredients

• Bone-In Prime Rib Roast
• Kosher salt or sea salt

Slow Roasting Prime Rib

1. Salt your roast all over the day before you plan on cooking it and refrigerate it overnight, uncovered.
   
2. When ready to roast, preheat your oven to 200°F and add your prime rib roast to the rack of a roasting pan. Season with pepper and olive oil.
   
3. Place the roasting pan in the oven until the center of the roast reads 120°F for medium rare, about 4 hours depending on the size of your roast. Use a meat thermometer.
   
4. When ready, remove the roast from the oven and tent it with foil. Rest for 20 minutes and turn up the oven temperature to 500°F.
   
5. Remove the foil and place the roast back in the oven for 10 to 15 minutes, until browned and crisp. Remove to a cutting board and let it rest 15 minutes before slicing and serving. Enjoy!
   

Prime Rib Recipe Tips

• Salt your roast and keep it uncovered on the sheet pan with a rack in the refrigerator the night before roasting. Bring it to room temperature before adding it to the oven by allowing it to rest for 2 hours outside of the fridge, for best results.
• Let your prime rib rest for 15 to 20 minutes before carving to lock in the juices.
• Always cut your roast against the grain.

How far ahead of time do I need to season prime rib?

Salt your roast all over with kosher salt or sea salt the day before you plan on cooking it, and refrigerate it overnight, uncovered. For best results, do not salt it more than 1 day ahead of time, and only add the pepper when ready to roast.

Prime Rib Recipes FAQs

What is the best pan to cook a prime rib in?

How long can I keep a prime rib roast in the fridge before cooking?

A raw roast should be kept no more than 3 to 5 days in the refrigerator before roasting.

Should prime rib be at room temperature before cooking?
