How to Cook a Prime Rib: Step-by-Step

Have your prime rib ready to go? Follow these simple steps for a beautifully cooked roast. This method works for both American Wagyu and Double R Ranch prime rib.


  1. Thaw
    Place your roast on a tray in the refrigerator. A large prime rib can take 3 to 4 days to fully thaw. If you are short on time, use our Quick Thaw Method.
  2. Heat Oven 
     Preheat your oven to 350°F.
  3. Season
    Generously season all sides with kosher salt or your favorite rub, such as SRF Rosemary Roast Seasoning or SRF x Just a Taste Coffee Rub. Make sure to cover the ends of the roast for even flavor.
  4. Roast

    Remember, time is only a guideline. The most accurate way to know when your roast is ready is by checking the internal temperature with a meat thermometer

    Use the prime rib temp chart below to cook to your preferred doneness:

    Preference

    Description Internal Temp. 
    Rare  Red, cool center 110°F
    Medium Rare  Red, warm center 120°F
    Medium  Pink throughout  130°F
    Medium Well  Primarily grey, sliver of pink 140°F


    Cooking Time Guidelines

    Only use times as a guideline. A thermometer should be used to determine doneness.

    Weight Medium Rare  Medium 
    About 1.5 lbs. 27 to 34 min.  35 to 42 min. 
    About 2 lbs.  40 to  49 min.  49 to 59 min.

    Getting the Correct Internal Temperature

  5. 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 it to rest for 20 to 30 minutes. During this time, the internal temperature will rise about 5 degrees and the juices will redistribute.
    Set the prime rib in a roasting pan and place it in the heated oven. Plan for approximately 15 to 20 minutes per pound.
  6. Slice and Serve
     Slice against the grain for the most tender results and serve immediately.

Other Prime Rib Cooking Methods

Not every prime rib is the same size or style, and sometimes you want a method that matches your kitchen setup or desired crust.

Reverse Sear Method

The reverse sear produces a rich, golden crust with a consistently cooked interior. It takes a little more technique but delivers restaurant-quality results.

  1. Preheat Oven: Set the oven to 275°F.
  2. Apply Seasonings: Season generously with salt and pepper, using Jacobsen or kosher salt. A favorite rub or paste can also be used.
  3. Roast in Oven: Place roast fat side up on a rack in a roasting pan. Cook for 20–25 minutes per pound. Only use time as a guideline; a thermometer is the best way to ensure your desired doneness.
  4. Remove from Oven: Pull at 110°F for rare, 120°F for medium rare, and 130°F for medium. Temperatures will rise about 10 degrees while resting.
  5. Rest: Allow the roast to rest for at least 30 minutes.
  6. Sear: Turn your oven to broil for the final 5 minutes. Place the roast back in and rotate every 90 seconds until all sides develop a deep golden crust.
  7. Slice & Serve: Cut against the grain and serve.
Small Roast – Two-Step (Skillet-to-Oven) Method

Perfect for petite roasts around 2 lbs or less, such as tenderloin or Manhattan roasts. This “steakhouse style” method gives a quick sear before finishing in the oven.

  1. Preheat & Heat Skillet: Set oven to 350°F. Heat a heavy skillet over medium-high heat and lightly coat with vegetable oil.
  2. Season: Generously season with kosher salt or Jacobsen sea salt and your preferred rub.
  3. Sear: Sear the roast in the hot skillet, turning to brown all sides evenly (about 2 minutes per side).
  4. Cook in Oven: Transfer skillet and roast to the oven. Roast for 25–50 minutes depending on desired doneness, turning once halfway through.
  5. Remove from Oven: Pull at 110°F for rare, 120°F for medium rare, and 130°F for medium. Temperatures will rise about 10 degrees during resting.
  6. Rest: Loosely tent with foil for 10–15 minutes.
  7. Slice & Serve: Carve against the grain and serve immediately.

Pro Tip: No matter the method, a thermometer ensures your prime rib temp is perfect every time. Shop American Wagyu Prime Rib or Double R Ranch Prime Rib to get started today.

 

The 500 Rule

What About the “500 Rule” for Prime Rib?

The “500 Rule,” also known as the closed-oven method, is a popular way to cook prime rib. Its appeal lies in the simplicity of the technique.

  1. Preheat the oven to 500°F.
  2. Place the seasoned roast in the oven and close the door.
  3. Calculate the cook time at 5 minutes per pound. (Example: 6 lb × 5 = 30 minutes.)
  4. Leave the roast in the oven for the calculated time.
  5. Turn off the oven, leave the roast inside, and let it rest for 2 hours.

According to the formula, this yields a medium-rare prime rib that’s ready to serve. While it works, a few caveats exist:

  • You can’t check internal temperature unless using a leave-in thermometer with an external readout.
  • Roasting at 500°F sears the exterior but can overcook outer layers.

Pro Tip: If this method works for you, continue using it. Otherwise, we recommend the reverse sear method for a perfectly pink interior and flavorful crust.

 

 

7 Common Prime Rib Cooking Mistakes (and How to Avoid Them)

Cooking prime rib is an art, but it’s easy to make small mistakes that can impact the final result. Whether you’re a seasoned cook or a first-timer, here are some of the most common mistakes and how to avoid them.

  1. Skipping the Thermometer

    Mistake: Relying solely on cooking time instead of checking the internal temperature.
    How to Avoid It: While cooking times are helpful, every oven is different. The only surefire way to ensure your prime rib is cooked to your preferred doneness is to use a thermometer. The ideal temperature for rare is 110°F, medium rare is 120°F, and medium is 130°F. Remember, the internal temperature will continue to rise by about 5°F while it rests.

  2. Overcooking the Prime Rib

    Mistake: Leaving the prime rib in the oven too long, thinking it will get better with more time.
    How to Avoid It: Prime rib is best when it’s juicy and tender. Overcooking can dry it out and turn it into an unappetizing roast. Always rely on your thermometer and pull it when it’s just a few degrees below your desired final temperature. Let it rest, and the internal temperature will rise to perfection.

  3. Not Resting the Prime Rib

    Mistake: Cutting into the roast immediately after removing it from the oven.
    How to Avoid It: Resting is essential to allow the juices to redistribute throughout the meat. After you remove the prime rib from the oven, tent it loosely with foil and let it rest for 20 to 30 minutes. This step ensures a juicy, tender roast and helps preserve that beautiful pink center.

  4. Not Bringing the Prime Rib to Room Temperature

    Mistake: Cooking a cold prime rib straight from the refrigerator.
    How to Avoid It: For even cooking, take your prime rib out of the refrigerator about 1 to 2 hours before cooking. Bringing the roast to room temperature allows for more consistent heat distribution and reduces the risk of uneven cooking, especially in the center.

  5. Forgetting to Season Generously

    Mistake: Using too little seasoning, or seasoning too late in the process.
    How to Avoid It: Prime rib benefits from a generous amount of seasoning. Whether you use kosher salt or your favorite rub, be sure to season all sides—don’t forget the ends! If you have time, consider applying salt the night before cooking to dry-brine the meat, which enhances moisture retention and flavor.

  6. Cooking Prime Rib in a Crowded Oven

    Mistake: Roasting your prime rib in a cramped oven, which can lead to uneven heat distribution.
    How to Avoid It: If possible, ensure there is enough space around the prime rib for air to circulate. A crowded oven can lead to uneven cooking, especially with larger cuts. If necessary, cook the roast on a rack to allow air to flow freely around the meat.

  7. Cutting Against the Grain Incorrectly

    Mistake: Slicing the prime rib with the grain instead of against it, resulting in chewy cuts.
    How to Avoid It: Always slice against the grain to ensure a tender, melt-in-your-mouth experience. Pay attention to the direction of the muscle fibers and cut perpendicular to them. This will help break them down and give you the most flavorful slices.

By keeping these common mistakes in mind, you can avoid the pitfalls and serve a perfectly cooked prime rib that will impress your guests every time.

Double R Ranch Cooked Prime Rib Bone-In Roast on plate

Prime rib, also called a standing rib roast, comes from the primal rib section of the cow—the same area ribeye steaks are cut from. Think of prime rib as ribeye before it’s sliced into individual steaks. Unlike ribeye, it’s cooked whole as a roast, delivering a tender, juicy texture and an unforgettable flavor experience.

It’s important to note that “prime rib” doesn’t always mean USDA Prime grade. The USDA grade and level of marbling are what truly determine the quality of a roast. The higher the marbling, the more flavorful and tender your prime rib will be.

When selecting a prime rib roast, look for one with abundant intramuscular fat (marbling). As the roast cooks, this fat melts into the meat, creating the luxurious eating experience prime rib is famous for.

At Snake River Farms, our American Wagyu prime ribs surpass the USDA Prime grading scale. In addition to our SRF Gold Label™ and SRF Black Label™, which offer the highest levels of marbling, we also offer USDA Prime and Choice grade prime ribs, giving you options for every occasion and taste preference.

Bone-in vs Boneless Prime Rib?

Boneless prime rib is full of flavor and easy to slice and serve. The biggest advantage of a bone-in roast is the dramatic presentation it creates. Few holiday centerpieces are more impressive than a bone-in prime rib arriving at the table.


Many home cooks consider bone-in roasts the height of tradition. Some believe the bone adds extra flavor, but tests by food experts like J. Kenji López-Alt of Serious Eats show that bone-in and boneless roasts taste nearly identical.


That said, bone-in roasts do have one real advantage: insulation. The bone slows down cooking, leaving the meat near the bone extra juicy and tender.


Pro Tip: To enjoy the best of both worlds, cut the bones away before cooking and tie them back on with butcher’s twine. After the roast is done, remove the rib section and return it to the oven for about 20 minutes. Slice the rack into individual ribs and serve alongside the roast as a bonus treat for your guests.

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

Roast Preparation Tips 

Cooking an unforgettable prime rib starts long before it goes into the oven. Here are a few expert tips from Snake River Farms to help you prepare your roast the right way. 

How Long to Defrost Prime Rib 

All Snake River Farms roasts ship frozen to maintain peak quality. Before cooking, we recommend thawing your roast completely in the refrigerator. Depending on the size, a frozen roast can take several days to fully defrost, so plan ahead. If you’re short on time, you can use the “speed thaw” method by placing the sealed roast in cool water to accelerate the process. For more details, see our full guide on how to thaw large cuts of beef and roasts.

Bring to Room Temperature 

For even cooking and a flavorful crust, try this restaurant-inspired tip: liberally apply kosher salt to the roast on all sides the night before you plan to cook it. Leave it uncovered in your refrigerator overnight. While the roast may appear dried on the surface, this process actually locks in moisture and creates a beautiful, flavorful crust once cooked.
