Have your prime rib and ready to cook?
Here are the simple steps for a beautifully cooked prime rib roast:
Thaw- Set your roast on a tray and place in the refrigerator. A prime rib can take 3 to 4 days to thaw. Not enough time? See Quick Thaw Method.
- Heat Oven - Set to 350°F.
- Open Package - Remove prime rib from packaging.
- Season - Generously apply kosher salt or your favorite rub, like SRF Rosemary Roast Seasoning. Be sure to cover all sides, including the ends.
- Roast - Set prime rib in a roasting pan and place in the heated oven. The approximate cook time is 15 to 20 minutes per pound. Temperature is the best way to know exactly when the roast is ready. Leave in oven until the internal temperature of your prime rib corresponds with your preferred finish. Refer to our prime rib temperature chart below for different levels of doneness.
- Rest - When your roast reaches the desired temperature, remove it from the oven and place it on a cutting board. Loosely tent with foil and allow to rest 20 to 30 minutes. The internal temperature will rise about 5 degrees and the juices will be reabsorbed.
- Slice & Serve - Cut your rested prime rib against the grain and serve.

Prime Rib Basics
What is Prime Rib
Prime rib, otherwise known as a standing rib roast, is a cut of beef that comes from the primal rib section of the cow. This is the same area ribeye steak is cut from. A simple way to understand prime rib is that it’s basically ribeye before it’s cut up. Instead of individual steaks, prime rib is cooked whole as a roast, producing a different and sought-after flavor experience.
“Prime” rib has become such a colloquial term that many assume these rib roasts are all USDA Prime graded prime ribs. But that is not always the case, which is why the USDA grade and quality of fat marbling should play a role in how you pick out a prime rib roast at the store.
How to Pick a Prime Rib Roast
When you shop for a prime rib roast, look for a roast with a high level of marbling – the fat contained within the muscles of the meat. As a roast heats in the oven, the intramuscular fat will melt and provide more flavor and a tender, juicy texture.
While choosing the ideal prime rib for your special dinner is a matter of personal preference, the level of marbling is a key measurement of the quality of a roast. The top two levels of marbling on the USDA grading scale are Choice and Prime.
All Snake River Farms American Wagyu prime ribs and roasts exceed the marbling amount found in USDA Prime. SRF Black is our American Wagyu marbling standard. Roasts in this category are high in marbling and will provide a memorable dining experience. The most marbled roasts available from Snake River Farms are SRF Gold. These are the ultimate prime ribs and roasts due to the intense marbling.
Bone-in vs Boneless Prime Rib?
Boneless prime ribs are full of flavor and are easy to slice and serve, while the biggest benefit to bone-in roasts is the impressive appearance they provide. There's something spectacular about setting a bone-in prime rib on your dining room table.
Many home cooks consider a bone-in roast the height of tradition. Some folks believe a bone-in roast provides added flavor. Myth-busting experts like Kenji Lopez-Alt of Serious Eats have conducted extensive taste tests and found boneless and bone-in roasts have a similar flavor profile
However, bone-in roasts do have real benefits. The bone insulates the meat from the oven’s heat which allows the meat surrounding the bone to cook slower, leaving those sections extra juicy and tender.
To make bone-in roasts easy to slice, we recommend cutting the bone from the roast and tying the rib section back to the roast with butcher's twine. When the roast is ready, place the rib bones back in the oven for 20 minutes. Cut the rack into individual ribs and place them on the serving tray as a special treat.

How Much Prime Rib Per Person
Eight ounces of cooked prime rib roast per person is a good serving size. If your table includes more robust appetites or if you want to plan for leftovers, add extra servings to your calculations. Boneless roasts will shrink about 20% and bone-in roasts lose about 30% of the final weight (because of the extra weight of the rib bones).
Refer to the below chart for serving sizes of different types of beef roasts:
| Roast Type | Servings (8 oz.) | Approx. Cook Time |
|---|---|---|
| Whole Tenderloin | 5 to 9 Servings | 1.5 to 2 Hours |
| Prime Rib/Ribeye Roast | 10 to 12 Servings | 2 to 2.75 Hours |
| Striploin | 12 to 15 Servings | 1.75 to 2.5 Hours |
| Eye of Ribeye | 8 to 10 Servings | 2 to 2.5 Hours |
| 1/2 Tenderloin | 3 to 4 Servings | 25 to 30 Minutes |
| Coulotte Steak | 3 to 4 Servings | 25 to 35 Minutes |
| Tri-Tip | 5 to 7 Servings | 25 to 35 Minutes |
| Manhattan | 5 to 7 Servings | 30 to 40 Minutes |
Preparation Tips
Now that you understand how to cook a delicious prime rib roast, the experts at Snake River Farm are here to give some quick tips on preparing your prime rib.
How Long to Defrost Prime Rib
All Snake River Farms roasts ship frozen to maintain optimal quality. Before cooking your roast, we recommend completely thawing it in the refrigerator. A completely frozen roast can take several days to thaw, so plan ahead.
If time is a factor, it is possible to “speed thaw” by placing the sealed roast in cool water to accelerate the process.
Bring to Room Temperature
A tip used by many restaurants is to liberally apply kosher salt to the roast on all sides the night before you plan to cook it. Leave it uncovered in your fridge overnight. The roast may appear dried out, but it will actually increase the prime rib's moisture when finished. The dry exterior produces an outside crust that adds texture and flavor.
