Boneless Prime Rib Recipe With A Garlic-Herb Crust • The Wicked Noodle (2024)

I host Christmas dinner every year. My mom does Thanksgiving, my does Christmas Eve and I get Christmas Day. My sister makes it fun, serving lots of different appetizers that we all graze on after the presents are opened (and we might sneak a few before and during, too).

But I get the easy part – making a big Christmas dinner for everyone.

I know you might think I’m crazy but hear me out. Making a juicy boneless prime rib is SO SIMPLE. I roughly calculate the time it will take for the roast to cook to the correct temperature so I know what time to put it in the oven. A leave-in thermometer tells me where the roast’s temperature is at while it cooks, so I can keep an eye on it. And an alarm goes off when it’s done!

I plan out my sides in advance and choose the ones that I can do most or all the work ahead of time. Since the boneless prime rib is the star of the show, I can keep the side dishes simple. These are the sides that I’ve made in the past that have worked well:

Side dishes for boneless prime rib

• Carrot Souffle – If you make any one of these side suggestions, let it be this one. Don’t worry, it’s not a “true” souffle and it really is easy! Everyone ALWAYS loves it, from toddlers to 80-year-olds. I promise you that everyone will be asking for the recipe.
• Green Beans Almondine – This is another super easy recipe and it goes perfectly with boneless prime rib. You can even blanch the beans ahead of time, then reheat them in the pan with the butter and almonds. And the beans taste great at room temperature, so if they’re ready a few minutes early, you don’t have to panic.
• Smashed Brussels Sprouts with Parmesan – Easy, delicious, not too fussy to make while doing other things. Not quite as easy as the Green Beans Almondine, but simple nonetheless.
• Easy Mushroom Risotto with Gorgonzola – This recipe is easy, yes, but more hands-on than the previous sides I mentioned. But it is SO GOOD, so if you want to make a dinner splash, this one is perfect!
• (with Parmesan) – This one went over big when I served it the first year. It’s partly make-ahead; you can blanch the green beans hours ahead then set them aside. Just before eating, sauté the mushrooms then toss with the green beans just to heat them up. Easy and delicious!
• Instant Pot Scalloped Potatoes – This is the quickest way I’ve found to make scalloped potatoes. Use your favorite shredded cheese or try it with a crumbled blue.

How to buy prime rib

How much prime rib will you need?

This will ultimately depend on how big a feast you’re making. The rule of thumb is 1/2 pound if it’s a feast, 3/4 pound if it’s a dinner with a few sides and 1 pound if there’s just one side to go with it.

Think about what you’ll be serving. How many appetizers? How long will people be there before you sit down to eat? If guests arrive an hour before dinner and you have a huge spread of appetizers, people are going to be half-full before they even sit down. If you have one cheese and cracker tray and it’s two hours until dinner, they might be a bit more hungrier.

Having said all that, I usually go for a pound per person (unless I’m feeding 20 people, of course). I do that because I absolutely LOVE the leftovers from a boneless prime rib recipe. We make garlic bread and use that for the bread on a prime rib sandwich with horseradish cream (YES, it’s as good as it sounds)!

What is prime rib called at the grocery store?

Your boneless prime rib likely won’t be labeled as such at the store. Other names for it are “standing rib roast”, “beef rib roast”, “boneless prime rib”, “boneless ribeye roast”, or “boneless rib roast.” When in doubt, ask the butcher! The last thing you want is to buy the wrong cut of meat.

Although prime rib contains “prime” in its name this does not mean that it is USDA Prime. It is called prime because the cut of meat comes from the primal rib section also known as the beef rib. Prime rib will most commonly be USDA choice. USDA Prime Grade Prime Rib often has to be specially ordered through a butcher or bought online from retailers such as Snake River Farms or Allen Brothers.

How much is a boneless rib roast?

That’s a difficult question to answer since prices are so different depending on where you live and it also depends on the USDA grade. I live on the U.S. East Coast and our USDA Choice boneless rib roasts are usually around $13-$30 per pound, depending on what grade the meat is.

Usually, around the holidays, rib roasts go on sale since they’re popular at that time of the year. I usually wait to buy mine until the day before unless I’ve found a deal I just can’t pass up.

You can also order a high-quality prime rib roast online. While I haven’t done this myself (yet), I’m told that Porter & York’s are great.

How to cook boneless prime rib in the oven?

Why is prime rib served rare?

The biggest reason is that if prime rib gets overcooked, all the fat cooks out of the meat and it will become dry and tough. It doesn’t have to be served rare, but IMO, anything over medium-rare should be avoided.

The great part about cooking a rib roast to medium-rare in the center (which is how I do it) is that the edge pieces will be more cooked. My dad, for example, prefers his prime rib well past medium-rare, so he gets the end pieces and everyone else gets the middle! It’s not overcooked at this point, so the end pieces are still juicy and tender.

What is the perfect temperature to cook prime rib?

My personal belief is that boneless prime rib should be cooked to medium-rare and no more. Cook the roast to 120-125° F for rare, and 130-135° F for medium-rare.

Be sure to use a leave-in meat thermometer!! I can’t stress this enough. The reason boneless prime rib is so easy is that the thermometer takes all the guesswork out of it. If I suddenly didn’t have one, I’d choose something else to make for dinner, because I’d never take the chance on overcooking such a beautiful piece of meat.

How long do you cook a boneless prime rib?

The cooking time rule of thumb is about 15-20 minutes per pound of meat. This also depends on the temperature of your oven since the higher the temperature, the faster it will cook.

The method that I use is to cook the roast at a high heat first, to lock in the juices and form a nice crust on its outside area. Then I reduce the temperature and cook it low and slow, which results in a juicy, tender roast. I usually cook an 8-pound roast, which takes about 3 hours from oven to table, including the time it will need to rest after cooking.

Should you cover prime rib while it’s cooking?

Nope! Leave it uncovered so it can form a beautiful, flavorful crust.

What about a bone-in rib roast?

Go for a bone-in rib roast if you’d like! I have an AMAZING recipe for a bone-in prime rib roast with a garlic-peppercorn wet rub. That’s usually my go-to recipe but I’m switching it up this year!
