Are you ready for the BEST Prime Rib recipe? This is a no-fail, meltingly tender and juicy, garlic-crusted prime rib that will have all your guests swooning. This standing beef rib roast is perfect for Christmas and the holidays, or any special occasion worthy of a little splurge.

Prime rib (also known as standing rib roast) is up there next to turkey, honey baked ham, filet mignon and beef tenderloin 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.

Prime Rib Ingredients

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, keep reading below.
Butter: This helps the seasoning stick to the meat and crisps up the outside. You could also use ghee if you’re dairy-sensitive.
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. Kosher salt has a coarser grain and helps to add texture to the outside crust.
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 ¾ pound per person is a better estimate, or even ½ pound if you’re serving it up with a lot of sides. Here’s a general guideline:

For 6 people: get a 4 ½ pound prime rib
For 8 people: get a 6 pound prime rib
For 12 people: get a 9 pound prime rib

Bone-in Versus 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 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 Versus 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 (which translates to 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 it’s best to plan ahead, as you may have to order it from your butcher.

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 to 3 hours before cooking.

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 to 3 hours before cooking.

Make the garlic herb butter. Preheat your oven to 450°F (230°C), 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 (if not, you can omit them). 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 325°F (160°C), and continue cooking until the internal temperature reaches your desired level of doneness (see chart below).

Let it rest. Remove the prime rib from the oven and let it rest for 20 to 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 ½-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 to 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 8½ pounds) – 1½ to 1¾ hours
4 ribs (9 to 10½ pounds) – 1¾ to 2¼ 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 to 10 degrees. So don’t overcook it! And always (always) let it rest, for 20 to 30 minutes.

Rare: remove at 110°F. Rested temp will be 117 to 120°F. Center is bright red, pinkish toward the outer edges.
Medium Rare: remove at 120°F. Rested temp will be 127 to 130°F. Center is very pink, slightly brown toward the outer edges.
Medium: remove at 130°F. Rested temp will be 137 to 140°F. Center is light pink, outer portion is brown.
Medium well: remove at 140°F. Rested temp will be 147 to 150°F. No pink.
Well: remove at 150°F. Rested temp will be 157 to 165°F.

Storage Tips

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. You can turn leftovers into prime rib tacos (they’re amazingly good) or enjoy slices reheated with the sides mentioned below. Here’s how to store the meat:

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 to 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 up to 3 months in the freezer.
To reheat: If the meat is frozen, thaw it in the fridge the day before you’d like to eat it. Then, just microwave it for a minute or two, until it’s warmed through.

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: Continue the garlic herb theme with these roasted potatoes (pictured above).
Green Beans with Shallots: These crisp green beans are light and fresh (pictured above).
Mashed Potatoes: Who can resist creamy mashed potatoes?
Roasted Brussels Sprouts: You’ll love the crispy outsides on these sprouts.

And while I’m serving this prime rib with a red wine au jus, you could also serve it up with a homemade horseradish sauce. Either one is divine!
