What Makes This The Best (and easiest!) Prime Rib Eye Roast Recipe
You know it’s a special occasion whenever a Prime Rib Roast is being prepared. This dinner party staple is one of my favorites to enjoy on holidays, birthdays, and anniversaries.
By popular demand, we always make roast beef either for Christmas Eve or Christmas dinner. Our slow roasted prime rib recipe is so easy and foolproof that it has been shared with countless friends and family. And I’m so excited to share it here!
But as impressive as this celebratory staple is, the secret is that prime rib is actually quite easy to make. To make this recipe you simply need:
- Standing rib roast or rib eye roast (more on this below)
- Kosher salt and pepper
- Vegetable or olive oil
By using just a few ingredients you really let the luxurious flavor of the bone-in rib eye roast shine. And while it might take some time to properly cook a standing rib roast, I promise each melt-in-your-mouth bite will be so worth the patience.
Here you’ll find our best tips for choosing and cooking a bone-in ribeye roast at home.
What is a Prime Rib?
The roast comes from the same part of the animal that the ribeye does: the primal rib section.
Although prime rib contains “prime” in its name, this does not mean that it is USDA Prime beef. Therefore be sure to double-check the grading of your beef before you purchase it. That way you make sure you’re actually buying USDA Prime meat for this bone-in rib eye roast recipe.
How to Choose the Best Rib Roast
We typically get our Prime cut Prime Rib roasts from Costco, because of the quality of their meat and their roasts are larger. You can also find quality prime rib roasts at Albertsons (Safeway/Vons), specialty grocery stores, or a butcher shop.
When I can’t find a prime cut of prime rib, I often get what’s labeled a rib roast, rib eye roast, rib steak. They all refer to the same general rib area of the animal, hence the “rib” portion of its name. You can find them at your local grocery store.
FYI, to be considered a ribeye the steak must be cut before the roast is cooked. The cuts are then labeled and sold as ribeye steaks.
Prime rib cuts are larger than ribeye cuts since they include the ribeye and the bone. A choice cut of rib eye roast will yield similar results with this ribeye roast bone in recipe.
Bone-in or Boneless Roast?
While both options are delicious, I prefer to buy a bone-in prime rib or rib roast. The bones actually add flavoring and marrow during roasting. You won’t want to miss that!
Not only are these cuts of meat more flavorful, but you can also actually use the bones to create your own v-rack for roasting. Here’s how:
- With a sharp knife, carefully remove cut bones from the roast.
- Once removed, invert the bones beneath the roast.
- Use cooking twice to anchor them to the prime rib by tying them on.
When inverted, the bones will elevate the roast from the roasting pan, but still provide flavoring and release marrow into the au jus.
If your roast is boneless, use a V-rack for roasting as described in the recipe below.
Expert Tips for Cooking a Bone in Ribeye Roast
First, make sure that you take the time to properly prepare the beef before cooking:
- Use a sharp knife to make cross-cuts in the fat pad on top of the rib eye. Be careful to not cut into the meat.
- Then, rub the rib roast with oil and salt.
- Refrigerate for at least 24 hours, up to 4 full days.
This prep-ahead recipe is great if you plan to make roast beef for Christmas dinner with lots of other dishes.
The next step in this nearly foolproof ribeye roast bone in recipe is to preheat the oven to 200 degrees Fahrenheit. Cooking low and slow is what gets the prime rib to that classic medium-rare temperature.
Then you want to briefly sear the standing rib roast in a hot skillet with oil. This locks in the flavor and creates a wonderful outer crust.
Let the ribeye rest for 10 minutes, and place on a V rack (or wire rack, as mentioned above) inside of a rimmed or roasting pan. Season generously with more salt and ground black pepper.
Then the secret to cooking a bone in ribeye roast to medium-rare perfection is to let it sit in the off oven for another 60 minutes until the temperature reaches 125 degrees Fahrenheit.
Remove the prime rib from the oven, and let rest for 15 minutes before slicing. If you cut the meat too soon you’ll lose all of the flavor in the juices, so don’t rush!
Then slice in 1″ to 1.5″ thick slices, like a steak cut, and serve.

Frequently asked Questions
Bold and tangy horseradish sauce is classic to pair with tender prime rib. Or try spicy horseradish mustard. You also can serve the pan juices (au jus) on the side.
Leftovers will keep well for up to 4 days in the refrigerator or 3 months in the freezer. Let the roast beef cool completely before transferring to an airtight container. If freezing, I also suggest you wrap the container in a layer of aluminum foil.
Enjoy this ribeye roast bone in recipe roast warm or cold by itself, or used to make other dishes. It’s great on sandwiches and in wraps, salads, or with cheese and crackers for a snack.
