Why I love this recipe:
- Easy: Cooking prime rib can seem intimidating, especially since it's an expensive cut of meat! But this recipe has simple ingredients and easy to follow instructions that will allow even the most novice cook to have success!
- Cheaper cooked from home: it's much cheaper to serve prime rib from home, then order from a restaurant! Most local grocery stores carry choice grade prime rib for between $14.99 to $15.99 per pound. I've found Costco to have the lowest prices for the best quality. They even sometimes carry prime grade meat.
How much do you need?
The rule of thumb for buying prime rib is to buy one pound per person. A bone-in standing rib roast will feed about 2 people per bone. Also, be sure to consider how many side dishes you plan to serve. If you are preparing a large holiday meal with plenty of other food you could plan on ½ – ¾ pound prime rib per person.
The Prime rib roast (aka standing rib roast) is taken from the back of the upper ribs of the cow and typically makes up about 7 ribs. You don't have to buy the whole section, just specify to your butcher how many pounds you would like.
Bone-in or Boneless Prime Rib:
Bone-in prime rib roasts are typically more flavorful and cook better than boneless prime rib, but boneless will also work great! If you buy a bone-in prime rib, ask the butcher to cut the bone off and tie it to the roast for you. This way you can cook the bones with the meat: they make a nice rack for the meat to sit on, but then you can easily remove them before carving the roast. If using a boneless prime rib, you will want to set it on a rack to roast. (I've had success using the wire rack from my instant pot set on top of my cast iron skillet.)
Cook Time and Temperature:
The length of time to cook prime rib depends on how rare you want the meat.
Start by cooking your prime rib at 500°F for 15 minutes and then lower the oven temperature to 325° F and cook for 10-12 min per pound for rare, or 13-14 min per pound for medium rare, or 14-15 min per pound for medium well.
A meat thermometer is essential to ensure you cook it perfectly!
Roast your prime rib until the thermometer registers:
- 115-120˚F for rare
- 125-130˚F for medium rare
- 135-140° F for medium
- 145-150 F° for medium well
Please keep in mind the meat temperature will continue to rise 5-10 degrees when it's resting out of the oven, so don't over cook it!
How to cook Prime Rib:
Let it rest. Remove your roast from the refrigerator about 1 hour before cooking to give it time to come to room temperature. Season it with a little bit of salt and cover it lightly with plastic wrap while is rests.
Prepare herb rub. Combine the salt, pepper, fresh thyme, rosemary, garlic and olive oil then rub it all over the outside of the roast. Place a bone-in roast with the bones down, in a cast iron, roasting, or other oven safe pan. Place a boneless rib roast on top of a rack, and then in your pan.
Cook the boneless or bone-in prime rib at 500 degrees for 15 minutes and then reduce the oven temperature to 325 degrees and continue cooking until the meat is 5-10 degrees away from the desired doneness temperature (see cooking temperature guidelines above or below in the recipe card).
Allow time to rest. Remove the prime rib from the oven then tent the entire roast with foil. Allow it to rest for 30 minutes–It will continue to cook the extra 5-10 degrees. Resting the meat is essential as it allows the juices to seal back into the meat. If you cut the meat too soon, the juices will run out and it will be chewy.
Carve and Serve. Spoon some of the extra sauce from the pan over the roast, if desired, or use it to make gravy. Cut the kitchen string holding the roast to the bones (if using a bone-in roast) and remove the bones before carving. Serve the best prime rib recipe with mashed potatoes, wedge salad, and homemade rolls.
Tips for Perfect Prime Rib:
- Use a meat thermometer. You can use a probe that stays inside the meat the entire time it cooks or you can use a simple instant read meat thermometer to check the prime rib cooking time. Either way, remember that each slice of meat is different and each oven is different. Don't take the chance of ruining such an expensive piece of meat.
- Don't over-cook. The meat will continue to cook once it’s taken out of the oven (your thermometer will continue to rise 5-10 degrees) so err on the side of taking your prime rib out early. If you take it out and it seems under-cooked, you can always cook it a little longer.
- Let it REST, As with most meat, you want to let it rest after cooking to allow the juices to settle in the meat, making it juicier and more tender. If you cut into your roast without letting it rest, the juices will rush out then the meat will be chewy.
- Cut meat across the grain. That means, notice the directional lines in the meat grain then slice perpendicular to them. If you cut along the grain then the meat will be tougher and chewier to eat.
Perfect Sides for Prime Rib:
- Perfect Mashed Potatoes or Twice Baked Potatoes
- Roasted Vegetables
- Homemade Rolls
- Classic Wedge Salad
- Skillet cornbread

Prime Rib Recipe
Equipment
Ingredients
- 5 pounds beef prime rib* (if larger, double the spices/seasonings)
- Sea salt
- 2 teaspoons freshly ground black pepper
- 2 teaspoons fresh rosemary
- 1 teaspoon fresh thyme
- 8 cloves garlic , minced
- 1/4 cup olive oil
- horseradish , for serving (optional)
Instructions
- Bring meat to room temperature: Remove prime rib from the refrigerator one hour before cooking. Season it on all sides with salt and cover it loosely with plastic wrap as it comes to room temperature. Prime rib roast will cook better and more evenly when it’s at room temperature.
- Adjust oven racks: When you are ready to cook the prime rib, lower/adjust your oven rack so the meat will cook in the center of the oven. Preheat the oven to 500 degrees F.
- Combine seasonings: In the meantime, mix together 1 ½ teaspoons salt, pepper, rosemary, thyme, garlic, and olive oil.
- Prepare roast: Pat the roast with paper towels. Spoon seasoning over it, rubbing it onto all sides. Place bone-in roast with the bones down, inside a roasting cast iron pan. Place a boneless roast on a rack inside the pan.
- Bake prime rib at 500 degrees for 15 minutes, then reduce the oven temperature to 325 degrees and continue baking until desired level of doneness. Use a meat thermometer to check the temperature of the meat:Rare: 120 degrees F (about 10-12 min/pound). Medium Rare: 130 degrees F (about 13-14 min/pound)Medium: 140 degrees F (about 14-15 min/pound)Medium Well:150 degrees FImportant: The meat will continue to cook as it rests out of the oven so remove it from the oven 5-10 degrees before it reaches your optimal temperature.)
- Rest: Remove it from the oven and tent it with foil. Allow it to rest for 30 minutes before carving.
- Carve prime rib roast by slicing against the grain into about ½ inch thick slices. Serve with horseradish, if desired.

Everyone absolutely loved this prime rib for Christmas Eve. Thank you!! My Wife wouldn’t let me take the leftovers to Christmas dinner because “they will eat it all”
I made the prime rib dinner two Christmases two Christmases ago and I had taken culinary classes to learn how to cook things like this and when I saw this recipe I was amazed everybody was amazed I cooked it and they loved it thank you for the recipe I cooked it almost every Christmas now and New Year’s it’s a better taste than turkey especially when you have turkey for Thanksgiving prime rib for Christmas is the best thing there is
I’ve never commented on a recipe before, but I had to for this one because we followed this recipe to a T and had one of the best NYE dinners to date. Considering how simple the recipe was, we were all blown away by how tender, juicy, and flavorful the prime rib roast turned out. This recipe created a meal that was better than any restaurant prime rib we’ve ever had. Thank you for sharing such a great recipe with the world!
Nice recipe with one glaring error.
Your direction is to take the roast out of the fridge one hour before cooking to get it to room temperature. This is erroneous. If you want the roast to be at room temperature take it out of the fridge at least 4 hours prior. At least!
I 100% agree. You need to take the roast out several hours before roasting.
Elliott, I 100% agree. I had a 6.6lb bone (cut, and strung back together) slim/long roast. I put it out at 0830am, started it into the oven at 1300(pm) – when I inserted thermostat, it was 50*F..
Was concerned, but it it did turn out wonderful still!
This is in the oven right now. I have followed the recipe to a tee and it’s been 70 minutes. Internal temp, with 3 different thermometers is approximately 60 degrees. What is happening?????
The BEST prime rib ever! It was so incredibly tasty. Everyone loved it. It’s even better than the ones I’ve had in restaurants. The only downside was that it didn’t give us much fat / liquid for Yorkshire pudding , but maybe our roast was too lean?
The rub never penetrated the roast after a 24 hour marriage in the fridge.
Followed the recipe exactly as it’s written for a 7.7lbs prime rib and it was a perfect medium rare. The whole family loved it and we’ll be making it again next Christmas! Thank you soooooo much for the recipe and easy to follow instructions.
I used this recipe for my Christmas dinner. I have never cooked prime rib before and needed some help. My prime rib turned out amazing!!! Everyone enjoyed it. Thank you!
Great recipe. Ours did take much longer (45 minutes) to get to temperature than the calcs provided. Took it out at 128 degrees and it went up to 135 degrees after resting 20-25 minutes. Perfectly pink in the middle! Flavor was great.
Decided to try this recipe with a Boneless Prime Rib. It was 4 1/2 lbs. Put in oven after preheating to 500°, for 30 minutes, then reduced to lowest setting of 170°.
I was monitoring internal temp at center without opening door. After 75 minutes, the temp was at 135°, so I took it out. If I had not had probe, and waited 2hours per directions, it would have been way overdone. Did I do something wrong??
Check your math on your size of roast. 15×4.5=67.5 minutes
The recipe states that you sear it in the 500 degree oven for 15 minutes not 30. That might be why it was cooking too quickly.
Directions call for 15 minutes at 500 Degrees. You say yours was cooked at 500 degrees for 30 minutes. Perhaps that was the difference..
This recipe was east and our prime rib was phenomenal. Thank you for this. I must’ve watched 100 YouTube videos and read just as many recipes before deciding on your. Thank god I found it.
First let me say that I don’t even like beef. I made an 8 1/2 lb bone in rib roast yesterday for Xmas and followed the recipe. It was outstanding and right up there with restaurant prime rib quality. Super tender and cooked rare with the ends more medium, seasoned to perfection with the fresh thyme and rosemary and garlic. I made a paste in the food processor and in addition to the olive oil I added about a teaspoon of dijon mustard, roasted at 500 for about 25 min. since it was such a large roast and then roasted at 325 for one hour. Rested for 30 minutes and the juices were enough to slather on the sliced beef and infused with the flavors of the rub.
The only recipe you will ever need to make a perfect roast – easy, not a lot of prep and delicious results.
Thanks for the nudge. Ive done this before but used older methods. Our 11.4 lb roast turned out great!
