Prime rib, a show-stopping centerpiece for any special occasion, is a cut of beef that’s both tender and flavorful. However, cooking it to the perfect level of doneness can be a challenge, especially when it comes to temperature. In this article, we’ll explore the possibility of cooking prime rib at 170 degrees and provide you with a comprehensive guide on how to achieve a deliciously cooked prime rib.
Understanding Prime Rib and Its Cooking Requirements
Before we dive into the specifics of cooking prime rib at 170 degrees, it’s essential to understand the characteristics of this cut of beef. Prime rib, also known as a standing rib roast, is a cut from the rib section of the cow. It’s a tender and flavorful cut, thanks to the marbling of fat that’s dispersed throughout the meat.
When it comes to cooking prime rib, the goal is to achieve a tender and juicy interior while maintaining a crispy, caramelized crust on the outside. To achieve this, it’s crucial to cook the prime rib to the right internal temperature.
Internal Temperature Guidelines for Prime Rib
The internal temperature of prime rib is critical in determining its level of doneness. Here are the internal temperature guidelines for prime rib:
- Rare: 130-135°F (54-57°C)
- Medium-rare: 135-140°F (57-60°C)
- Medium: 140-145°F (60-63°C)
- Medium-well: 145-150°F (63-66°C)
- Well-done: 150-155°F (66-68°C)
As you can see, the recommended internal temperature for prime rib is significantly higher than 170°F (77°C). However, we’ll explore the possibility of cooking prime rib at this temperature later in the article.
The Science Behind Cooking Prime Rib at 170 Degrees
Cooking prime rib at 170°F (77°C) is a relatively low temperature, especially when compared to the recommended internal temperatures mentioned earlier. However, this temperature can be beneficial in certain situations.
When you cook prime rib at 170°F (77°C), you’re essentially using a low-and-slow cooking method. This approach can be beneficial for several reasons:
- Even cooking: Cooking prime rib at a low temperature ensures that the heat penetrates the meat evenly, reducing the risk of overcooking the exterior before the interior reaches the desired temperature.
- Tenderization: Low-temperature cooking can help break down the connective tissues in the meat, resulting in a tender and juicy prime rib.
- Reduced shrinkage: Cooking prime rib at a low temperature can help reduce shrinkage, which means you’ll end up with a larger, more impressive roast.
However, cooking prime rib at 170°F (77°C) also has its drawbacks. For example:
- Longer cooking time: Cooking prime rib at a low temperature requires a longer cooking time, which can be a challenge for those who are short on time.
- Risk of undercooking: If you’re not careful, cooking prime rib at 170°F (77°C) can result in an undercooked roast, especially if you’re using a smaller prime rib.

What is the ideal internal temperature for cooking prime rib?
The ideal internal temperature for cooking prime rib depends on the level of doneness desired. For medium-rare, the internal temperature should be at least 130°F – 135°F (54°C – 57°C), while medium should be at least 140°F – 145°F (60°C – 63°C). It’s essential to use a meat thermometer to ensure the prime rib reaches a safe internal temperature. Cooking prime rib to the correct internal temperature ensures food safety and optimal flavor.
It’s also important to note that the internal temperature of the prime rib will continue to rise after it’s removed from the oven, a phenomenon known as “carryover cooking.” This means that the internal temperature may increase by 5°F – 10°F (3°C – 6°C) after the prime rib is removed from the oven. Therefore, it’s crucial to remove the prime rib from the oven when it reaches an internal temperature that is 5°F – 10°F (3°C – 6°C) lower than the desired final temperature.
Can you cook prime rib at 170 degrees?
Cooking prime rib at 170°F (77°C) is not recommended, as it may result in overcooking and a loss of tenderness. Prime rib is best cooked at a higher temperature, typically between 325°F – 375°F (165°C – 190°C), to achieve a nice crust on the outside while keeping the inside tender and juicy. Cooking at a lower temperature like 170°F (77°C) may lead to a longer cooking time, which can cause the prime rib to become dry and tough.
However, if you’re looking to cook prime rib at a lower temperature, it’s better to use a method like slow cooking or braising. This involves cooking the prime rib in liquid over low heat for an extended period, typically 2-3 hours. This method can result in a tender and flavorful prime rib, but it’s essential to monitor the internal temperature to ensure food safety.
How do you achieve a perfect crust on prime rib?
Achieving a perfect crust on prime rib requires a combination of proper seasoning, high heat, and a bit of patience. Before cooking, season the prime rib liberally with salt, pepper, and any other desired herbs or spices. Then, place the prime rib in a hot oven, typically at 425°F – 450°F (220°C – 230°C), for 15-20 minutes to create a crust. After the initial crust formation, reduce the oven temperature to 325°F – 375°F (165°C – 190°C) to finish cooking the prime rib.
Another technique to achieve a perfect crust is to use a broiler or grill. Place the prime rib under the broiler or on the grill for 2-3 minutes per side to create a crispy, caramelized crust. This method adds a nice texture and flavor to the prime rib, but be careful not to overcook the meat.
What is the best way to let prime rib rest?
Letting prime rib rest is an essential step in the cooking process, as it allows the juices to redistribute and the meat to relax. After removing the prime rib from the oven, place it on a wire rack or a cutting board, and let it rest for 20-30 minutes. During this time, the internal temperature of the prime rib will continue to rise, and the juices will redistribute, making the meat more tender and flavorful.
It’s essential to let the prime rib rest in a warm, draft-free area, away from direct heat or cold surfaces. You can also cover the prime rib with foil to keep it warm and prevent it from drying out. After the resting period, slice the prime rib against the grain, and serve immediately.
Can you cook prime rib in advance?
Cooking prime rib in advance can be a bit tricky, as it’s essential to ensure the meat remains safe and flavorful. If you need to cook prime rib ahead of time, it’s best to cook it to the desired internal temperature, then let it rest for 20-30 minutes. After the resting period, slice the prime rib and refrigerate or freeze it until serving.
When reheating cooked prime rib, it’s essential to heat it to an internal temperature of at least 145°F (63°C) to ensure food safety. You can reheat the prime rib in the oven, on the stovetop, or in the microwave, but be careful not to overheat the meat, as it can become dry and tough.
How do you slice prime rib?
Slicing prime rib requires a bit of skill and patience, but with the right techniques, you can achieve beautiful, even slices. To slice prime rib, use a sharp knife, preferably a carving knife or a serrated knife, and slice against the grain. Start by slicing the prime rib into thick slices, about 1-2 inches (2.5-5 cm) thick, then slice each slice into thinner pieces if desired.
It’s essential to slice the prime rib when it’s still warm, as this makes it easier to slice and helps the meat retain its juices. You can also use a meat slicer or a mandoline to slice the prime rib, but be careful not to apply too much pressure, as this can cause the meat to tear.
What are some common mistakes to avoid when cooking prime rib?
When cooking prime rib, there are several common mistakes to avoid, including overcooking, under-seasoning, and not letting the meat rest. Overcooking can result in a dry, tough prime rib, while under-seasoning can lead to a lack of flavor. Not letting the meat rest can cause the juices to run out of the meat, making it dry and tough.
Other common mistakes to avoid include not using a meat thermometer, cooking the prime rib at too low a temperature, and slicing the meat too soon after cooking. By avoiding these mistakes, you can achieve a perfectly cooked prime rib that’s tender, flavorful, and sure to impress your guests.
