What Is Prime Rib?

Before we dive into answering the burning question of whether to cook prime rib at 325 or 350, it’s important to know what exactly prime rib is. Also known as a standing rib roast, prime rib is a popular and decadent cut of beef that is usually roasted in the oven. It’s typically served during special occasions such as holidays or family gatherings due to its rich flavor and impressive presentation. Prime rib comes from the primal rib section of a cow, hence the name “rib” roast, and is known for its generous marbling which makes it tender and juicy when cooked just right.

Is Prime Rib And Rib Eye The Same?

Ribeye steaks are cut from the rib roast, also known as prime rib. To be considered a ribeye, the steak must be cut before the roast is cooked, so it doesn’t necessarily have to be a rib eye-shaped steak. However, both prime rib and ribeye come from the same section of the cow and are known for their marbling and tenderness.

Do You Cook Prime Rib At 325 Or 350?

Prime rib is typically cooked at 325°F for an estimated duration of 15-20 minutes per pound. Bone-in roasts may require slightly more time due to the slower heating of the bone, while boneless cuts tend to lean towards the lower end of the time range. As for the temperature, many recipes recommend cooking at 325°F to achieve a medium-rare doneness, while others suggest 350°F for a more well-done roast. Ultimately, the choice between 325 or 350 depends on personal preference and desired level of doneness. After knowing the answer to the question do you cook prime rib at 325 or 350.

The Difference When Cooking Prime Rib At 320 Or 350

While the difference between cooking prime rib at 325 or 350 may seem insignificant, it can actually have a significant impact on the final result of your roast. A lower temperature of 325°F will result in a more evenly cooked and tender prime rib, while cooking at 350°F may lead to a slightly tougher and less juicy roast. However, if you prefer a well-done prime rib, cooking at 350°F may be the way to go. Just be sure to keep a close eye on the internal temperature of the roast and use a meat thermometer to ensure it reaches your desired level of doneness.

Ingredients Do You Need To Make A Prime Rib

Along with the prime rib itself, there are a few key ingredients and tools you’ll need to make a delicious and perfectly cooked roast. These include:

• Salt: A generous amount of salt is essential for seasoning the prime rib before cooking. It helps enhance the natural flavors of the meat.
• Pepper: Freshly ground black pepper pairs well with prime rib’s rich flavor.
• Garlic: Whether you use minced garlic or whole cloves, this aromatic ingredient adds depth and flavor to the roast.
• Fresh Herbs: Adding fresh herbs such as rosemary, thyme, or sage can elevate the flavor profile of your prime rib.
• Meat thermometer: As mentioned before, a meat thermometer is crucial in determining when the prime rib has reached your desired level of doneness. 
• Roasting pan: A roasting pan with a rack is recommended for even cooking and to catch any drippings for making gravy.
• Aluminum foil: Covering the prime rib with aluminum foil during cooking helps retain moisture and create an evenly cooked roast.

How To Season Prime Rib?

Once you have all your ingredients and tools ready, it’s time to season the prime rib. To really let the flavors shine, it’s best to keep it simple with a basic seasoning of salt, pepper, and garlic. Here’s a quick guide on how to season your prime rib:

1. Remove the roast from the refrigerator at least an hour before cooking to allow it to come to room temperature. This will help it cook more evenly.
2. Preheat your oven to either 325°F or 350°F, depending on your preferred cooking temperature.
3. Pat the prime rib dry with paper towels and place it in a roasting pan with the fatty side facing up.
4. Rub a generous amount of salt all over the roast, making sure to cover all sides evenly.
5. Season with freshly ground pepper and minced garlic, rubbing it into the meat as well.
6. If desired, add fresh herbs on top of the roast for added flavor.
7. Place the prime rib in the oven and cook according to your preferred temperature and time (15-20 minutes per pound at 325°F or slightly less at 350°F).
8. Check the internal temperature of the roast using a meat thermometer. For medium-rare, it should read around 135-140°F, while well-done will be around 150-160°F.
9. Once it reaches your desired level of doneness, remove the prime rib from the oven and let it rest for at least 15-20 minutes before carving and serving.

How To Cook The Best Prime Rib?

Now that you know all the key information about prime rib, including whether to cook it at 325 or 350 and how to season it, it’s time to put everything together to cook the best prime rib. Here are some additional tips for achieving a perfectly cooked roast:

• Let the prime rib rest: As mentioned before, letting the roast rest after cooking is crucial. This allows the juices to redistribute and results in a more tender and juicy prime rib.
• Invest in quality meat: The quality of your prime rib will greatly impact the final result. Be sure to choose a well-marbled, high-quality cut for the best flavor and texture.
• Use a meat thermometer: We can’t stress this enough! A meat thermometer is the best way to ensure your prime rib is cooked to perfection. Don’t rely on just timing alone as each roast may vary in size and shape.
• Consider using a reverse-sear method: If you want a perfectly even pink color throughout your prime rib, consider using the reverse-sear method. This involves cooking the roast at a low temperature (around 200°F) for a longer period, then finishing it off with a quick sear at a high temperature (around 450°F). This will result in a more evenly cooked and tender prime rib.

How Long To Cook Prime Rib 325 Or 350?

As mentioned before, the general rule of thumb for cooking prime rib is 15-20 minutes per pound at 325°F. However, this can vary depending on factors such as the size and shape of the roast, oven temperature accuracy, and personal preference for doneness. A good way to ensure your prime rib is cooked to perfection is by using a meat thermometer to check the internal temperature. Here are some general guidelines for cooking prime rib at different temperatures:

• For a medium-rare roast, remove from the oven at 135-140°F (15 minutes per pound at 325°F).
• For a medium to medium-well roast, remove from the oven at 145-150°F (18 minutes per pound at 325°F).
• For a well-done roast, remove from the oven at 150-160°F (20 minutes per pound at 325°F).

How To Test If Your Prime Rib Is Done?

As mentioned throughout this document, using a meat thermometer is the best way to determine if your prime rib is done. However, in case you don’t have one on hand, there are a few other methods you can use to test for doneness:

• Hand test: Use your fingers to gently press on the top of the roast. If it feels firm and springs back slightly, it’s likely medium-rare. If it feels firmer and bounces back more, it’s likely medium to well-done.
• Juices test: To check for doneness by the color of its juices, use a spoon to carefully tilt the pan and collect some drippings from the roast. If they are clear or lightly pink, your prime rib is likely medium-rare. If they are pink or reddish, it’s likely more medium to well-done.
• Visual test: If your prime rib has reached an internal temperature of 135°F, you can visually check for doneness by cutting into the thickest part of the meat. It should have a pink and juicy center with slight browning around the edges. If it’s all brown, it may be overcooked.
