It’s Not A Holiday Dinner Without The Best Prime Rib Recipe
Prime rib (also known as standing rib roast) is up there next to turkey in terms of intimidating recipes. It’s a big ‘ol chunk of meat that’s usually the centerpiece of a holiday meal. And let’s be honest, you don’t want to accidentally over cook it or mess it up, especially if you have guests over.
Adding to the intimidation…prime rib is also super pricey. But if you’ve enjoyed a perfectly roasted prime rib, you also know that it’s worth every penny for that beautiful, show-stopping piece of meat.
So let’s jump to the good news – it’s really easy to cook! Sure, you may find different cooking methods online, like a reverse sear, but I promise that if you stick with this simple, no-fail prime rib recipe you’ll get raving accolades all around. You know my motto, simple and foolproof is best.
Ingredients for the Best Prime Rib
A cut of meat this good doesn’t need much. Heck, simple salt and pepper works just fine. But today, we’ll add a few garlic cloves and herbs for the ultimate flavorful crust.
- Prime Rib: Grab a bone-in prime rib from your butcher. For details on picking the best one, read below.
- Butter: This helps the seasoning stick to the meat and crisps up the outside. You could also use ghee or oil for dairy-free.
- Herbs: Fresh rosemary and thyme pair beautifully with the garlic.
- Salt: You need a good amount of this! And make sure to use Kosher salt and not table salt.
- Pepper: Freshly cracked black pepper is best, if you have it.

What Size Prime Rib to Buy?
The general rule of thumb is 1 pound of prime rib per person. But in my experience, that’s a lot of meat! I think 3/4 pound per person is a better estimate, or even 1/2 pound if you’re serving it up with a lot of sides. Here’s a general guideline:
- For 6 people: get a 4 1/2 pound prime rib
- For 8 people: get a 6 pound prime rib
- For 12 people: get a 9 pound prime rib
Bone-in vs Boneless Prime Rib
You have the option of purchasing either a bone-in or boneless prime rib. Both work just fine in this recipe, though I personally prefer a bone-in. The bones act as a natural rack, keeping the meat elevated when cooking, and they insulate the meat, keeping it extra juicy.
Pro Tip: Ask your butcher to cut the bones off, but then tie them back on! This gives you all the benefits of the bones with none of the work of having to slice them off. You just have to cut the string and remove the bones before serving. Super easy!
Prime vs Choice Cut – Which is Better?
Don’t confuse the name prime rib with the grade of meat. Prime rib can come in prime or choice cuts. Prime cuts are the most expensive and have beautiful fat marbling (aka – lots of delicious flavor!). Choice cuts have slightly less marbling, and are slightly cheaper.
Pro Tip: Most grocery stores only carry choice cuts, and often only on the weekends. If you want a prime cut plan ahead, as you may have to order it from your butcher.
Room Temperature Meat is Key
To ensure the prime rib is cooked evenly it MUST be at room temperature before going into the oven. Otherwise you’ll end up with well-done meat on the ends and raw meat in the middle, which is definitely not ideal. So remember to remove it from the fridge 2-3 hours before cooking.
Equipment You’ll Need
All you need are three basic items for the perfect prime rib – an oven-safe pan or roasting tray, a thermometer, and a sharp knife.
- Pan or Roasting Tray: I prefer a sturdy, oven-safe, cast-iron pan for this recipe (assuming my roast fits in the pan). Because then it’s really easy to make the au jus with the leftover juices in the pan on the stove. If you’re cooking a large roast though, you’ll likely need a larger roasting pan.
- Thermometer: The most important thing to make the BEST prime rib is a thermometer. Nailing the right temperature is key! You can use a probe thermometer (that you’ll leave in the meat), an instant read thermometer, or a basic meat thermometer.
- Knife: A good sharp knife is essential to those beautiful cuts. You could use either a carving knife or chef’s knife.
How to Cook Prime Rib
Remove the prime rib from the fridge. Let it come to room temperature for 2-3 hours before cooking.
Make the garlic herb butter. Preheat your oven to 450F, then mix together the butter, herbs, salt, and pepper in a small bowl.
Pat and coat. After the prime rib has come to room temperature, pat it down with a few paper towels to remove any moisture. Then slather it all over with the garlic herb butter mix.
It’s time to roast it. Place the prime bones side down in an oven-safe pan or roasting pan. Place onion slices around the meat if you plan to make the red wine au jus. Then roast the prime rib for 20 minutes at the high temperature, to sear the outside and create a crust. After you’ve seared the outside, reduce the temperature to 325F, and continue cooking until the internal temperature reaches your desired level of done (see chart below).
Let it rest. Remove the prime rib from the oven and let it rest for 20-30 minutes. You can tent it with aluminum foil to keep it warm.
Slice it up. Remove the strings that are keeping the bones attached or slice the bones off the meat. Then, carve the prime rib into thick 1/2-inch slices and serve with the red wine au jus.
How Long to Cook Prime Rib
I’m cooking a 6 pound prime rib for this recipe, which will take about an hour and a half. Estimate 13-15 minutes per pound for medium-rare. If your prime rib is larger or smaller you’ll need to adjust the cook time. Here are a few estimates, but remember to always go by internal temperature, not time. Especially as all ovens cook slightly differently.
- 2 ribs (4 to 5 pounds) – 60 to 70 minutes
- 3 ribs (7 to 8.5 pounds) – 1-1/2 to 1-3/4 hours
- 4 ribs (9 to 10.5 pounds) – 1-3/4 to 2-1/4 hours
Standing Rib Roast Internal Temperature
It’s important to remember that there will be residual heat and carryover cooking, once you remove the prime rib from the oven. That means the internal temperature will continue to rise 7-10 degrees. So don’t overcook it! And always (always) let it rest, for 20-30 minutes.
- Rare – remove at 110°F. Rested temp will be 117-120°F. Center is bright red, pinkish toward the outer edges.
- Medium Rare – remove at 120°F. Rested temp will be 127-130°F. Center is very pink, slightly brown toward the outer edges.
- Medium – remove at 130°F. Rested temp will be 137-140°F. Center is light pink, outer portion is brown.
- Medium well – remove at 140°F. Rested temp will be 147-150°F. No pink.
- Well – remove at 150°F. Rested temp will be 157-165°F.
How to Store Leftovers
If you have leftovers after your dinner or party, not to worry, you can save them! You definitely don’t want this expensive cut of meat going to waste. So here’s how to enjoy it again in the future!
- In the fridge: If you have just a few slices and plan to eat it later that week, you can store leftovers in a sealed storage container in the fridge for 4-5 days.
- In the freezer: If you have more leftovers than you can handle, freeze them! Let the meat cool completely. Then slice it up, place it in freezer safe bags, and squeeze all the air out. It’ll last for about a month in the freezer.
- To reheat: If the meat is frozen, thaw in the fridge the day before you’d like to eat it. Then, just microwave for a minute or two, until it’s warmed through.
You can enjoy leftover prime rib with any of the sides mentioned below, or you can turn it into prime rib tacos as well (they’re amazingly good!).
What to Serve with Prime Rib?
I always love a good potato and veggie side dish. Some of my favorite sides to serve with prime rib include…
- Garlic Herb Roasted Potatoes (pictured above)
- Green Beans with Shallots (pictured above)
- Mashed Potatoes
- Roasted Brussels Sprouts
- Mashed Cauliflower

Best No-Fail Prime Rib (Garlic Herb Crust)
- 6 pounds prime rib, bone-in (with bones cut off and tied back on)
- 1/2 cup butter, softened
- 6 garlic cloves, minced
- 1 tablespoon kosher salt
- 1 teaspoon finely chopped fresh thyme
- 1 teaspoon finely chopped fresh rosemary
- 1 teaspoon black pepper
- 1 onion, quartered (if making the red wine au jus)
Red Wine Au Jus
- 1/4 cup drippings from prime rib pan, make sure to separate the fat from the drippings
- 2 cups beef broth
- 1 1/2 cups red wine
- Optional: 1 tablespoon cornstarch or arrowroot powder (in a slurry) to thicken
- Remove the prime rib from the fridge 2-3 hours before cooking, and allow it to come to room temperature.
- Preheat your oven to 450F/230C. In a small bowl, mix together the butter, garlic, salt, thyme, rosemary, and black pepper.
- After the prime rib has come to room temperature, pat it down with paper towels to make sure it's dry. Then rub the entire outside of the prime rib with the herb butter mixture.
- Place the prime rib in an oven-safe pan or roasting tray with the bones-side down, fat-side up. Place the onion slices in the pan around the meat, if you're making the red wine au jus. If not, you can omit the onions.
- Cook the prime rib in the center of the oven for 20 minutes at 450F. It should get a nice sear on the outside. If not, cook it a few minutes longer. Then reduce the temperature of the oven to 325F and continue cooking until the internal temperature reaches 120F (about an hour and a half), for medium-rare. But go by temperature, not time, as it will depend on the size of your prime rib and your oven.
- Remove the prime rib from the oven and let it rest for 20-30 minutes. You can tent it with aluminum foil to keep it warm. Then, remove the string and bones, and slice it up into thick 1/2" slices.
Red Wine Au Jus
- After you've removed the fat from the pan, add up to 1/4 cup of drippings back in along with the beef broth and red wine. If you have leftover herbs, you can toss those in as well.
- Simmer this for about 15 minutes, or until the liquid has reduced by half. It's meant to be a thin sauce, but if you'd like to add a little bit of a thickener, you can do that as well. Strain the au jus to remove the onion and any browned bits, then drizzle over the prime rib.
- If you can, get your butcher to cut the bones off the prime rib, and tie them back on for you. It’s much easier to simply snip the string and remove them at the end!
- Keep an eye on the internal temperature even while the prime rib is resting. If you rest it too long, the temperature may increase a bit too much.
- For the red wine au jus, I recommend a fat separator, to ensure your sauce isn’t too greasy.
