Prime Rib 500 Degree Method
Perfect Prime Rib Every Time: The Foolproof 500 Degree Method
If making prime rib has ever felt intimidating, let me tell you right now — this method takes all the guesswork out of it. The 500 degree prime rib method is hands-down my favorite way to prepare this special cut of meat because it’s reliable, simple, and produces consistently incredible results. Whether you’re serving it for Christmas, a holiday gathering, or a special Sunday dinner, this is one of those recipes that makes everyone think you worked way harder than you actually did.
What makes this method so unique is that the oven does most of the work for you. You start with high heat to create a flavorful crust, then turn the oven off and let the roast finish cooking slowly and evenly without opening the door. No constant temperature checking. No stressing. Just tender, juicy, perfectly medium-rare prime rib — every single time.
Before You Start: What Really Matters
The most important part of this recipe happens before the prime rib ever goes into the oven. First, the roast must be completely thawed. Prime rib is a dense cut of meat, and rushing this step can lead to uneven cooking. Plan on 5–7 hours per pound to thaw the meat in the refrigerator. I always add an extra day to that calculation just to be sure it’s fully thawed all the way through.
Once thawed, bringing the prime rib to room temperature is critical for this cooking method. Place the roast on a plate on the counter for 4–6 hours before roasting. This allows the meat to cook evenly from edge to center and helps prevent a cold middle.
When you’re ready to roast, place the prime rib fat-side up in a roasting pan. If it’s bone-in, the bones should be on the bottom. If the bones were cut and tied back on by the butcher, leave the string in place while roasting to help the meat retain its shape. You can remove the ties before carving.
Flavor Starts with Herb Butter
This herb butter may be simple, but it adds incredible flavor to the finished roast. Softened butter mixed with garlic, onion powder, thyme, and basil creates a savory crust that melts into the meat as it cooks.
Generously season the fat side of the prime rib with salt and pepper, then spread the herb butter evenly over the top. As the roast cooks, the fat renders and carries that seasoning and herb flavor throughout the meat.
The 500 Degree Method (Yes, It Really Works)
Preheat your oven to 500 degrees. Once fully heated, place the prime rib in the oven uncovered and roast for 5 minutes per pound, using the actual weight of the meat listed on the package.
When the roasting time is complete, turn the oven off completely and leave the meat inside with the door closed for 2 full hours. Do not open the oven door during this time — the trapped heat is what finishes cooking the roast evenly without drying it out.
After the 2 hours are up, remove the prime rib from the oven, tent it loosely with foil, and allow it to rest for 10–15 minutes before carving. This resting time helps the juices redistribute so each slice stays tender and juicy.
This method is designed to produce a perfect medium-rare prime rib at about 125 degrees and works beautifully for both bone-in and boneless roasts without any adjustments.
Homemade Au Jus That Takes It Over the Top
Prime rib is delicious on its own, but serving it with a rich au jus takes it to the next level. Using a coffee filter to create an herb bundle is an easy trick that adds flavor without leaving herbs floating in the finished sauce.
Simmer water, beef bouillon cubes, Worcestershire sauce, and the herb bundle for about 20 minutes. This au jus can be made ahead of time and reheated just before serving, which is especially helpful when preparing a holiday meal.
Don’t Toss the Bones – Turn Them Into Something Amazing
If you’re using a bone-in prime rib, those bones are far too valuable to throw away. Once the meat is carved off, place the bones into a slow cooker and add enough water to cover them. Add onion, carrots, garlic, basil, thyme, salt, and pepper. Cover and cook on low for 8–12 hours to create a rich, flavorful beef broth.
Once the broth is finished cooking, strain out the bones and vegetables. As you strain it, you’ll notice little bits of tender beef — be sure to save those. They’re perfect for adding to my Homemade Vegetable Beef Soup, and it’s one of my favorite ways to turn a special holiday meal into another comforting, homemade dinner.
Planning Tips for Stress-Free Timing
One of the best things about the 500 degree method is how predictable it is. Because the roasting time is based on the exact weight of the meat, you can easily work backward to know when to put the roast in the oven.
For example, a 5.25 lb prime rib will roast for about 26–27 minutes at 500 degrees, then remain in the oven (turned off) for 2 hours. This makes it easy to plan the rest of your meal without stress.
When purchasing your roast, plan on:
- ½–¾ lb per person for boneless prime rib
- 1 lb per person for bone-in prime rib

- 5-6 lb Prime Rib Roast with or without the bone
- ½ cup Butter room temperature
- 2 tsp Garlic minced
- 1 tsp Onion Powder
- ½ tsp Thyme
- ½ tsp Basil
- 1 Salt & Pepper
- 2½ cups Water
- 4-5 cubes Beef Boullion
- 1 tbsp Worcestershire Sauce
- ¼ tsp Thyme
- 1 tsp Marjoram
- 1 tsp Basil
- 1 tsp Garlic minced
Instructions
- The prime rib must be thawed. It will take 5-7 hours per pound to thaw the meat in the fridge. I add 1 extra day to that calculation to make sure it is completely thawed.
- It is very important to bring the prime rib roast to room temperature prior to roasting. Place the completely thawed prime rib on a plate on the counter for 4-6 hours.
- Place the prime rib roast into the roasting pan fat side up, and if it is bone-in the bone side should be down. If the prime rib roast has the bone cut and tied, keep it tied for roasting. You can remove the ties prior to serving.
- In a small bowl make the herb butter by mixing the butter, 2 tsp minced garlic, 1 tsp onion powder, ½ tsp thyme, and ½ tsp basil.
- Generously season the fat side of the meat with salt and pepper. Spread the herb butter over the fat side of the prime rib roast.
- Preheat oven to 500 degrees.
- Place the meat in the oven uncovered and roast for 5 minutes per pound using the actual weight of the meat. Turn the oven off and leave the meat in the oven with the door closed for 2 hours. No peeking!
- Remove the prime rib from the oven, tent loosely with foil, and allow it to rest for 10-15 minutes before carving.
- To make the Au Jus, you will make an herb bundle by using a coffee filter. In the center of the coffee filter add ¼ tsp thyme, 1 tsp marjoram, 1 tsp basil, 1 tsp minced garlic. Gather the coffee filter and tie closed with string or a bread tie, and place in the small saucepan. Add the water, bouillon cubes, and Worcestershire sauce. Over medium heat, bring to a boil, and allow to simmer for 20 minutes before serving. Remove the herb bundle before serving. This can be made in advanced and reheated prior to serving.
- Serve the carved prime rib with the au jus.
