Quantity per Person

I need to make sure I have enough prime rib per person so that no one goes hungry at my dinner party. Calculating the right quantity of prime rib can be crucial, and I want to ensure that everyone gets a satisfying portion.

To determine the amount needed, there are a few tips to keep in mind. For boneless prime rib, it is recommended to allot one pound per person as a main course. If you opt for bone-in prime rib, a good rule of thumb is to allow for two persons per bone.

Additionally, when cooking prime rib, it’s important to follow proper techniques and use a reliable meat thermometer to monitor the internal temperature. Perfectly cooked prime rib will leave your guests satisfied and craving for more.

Quantity for 8 Adults

Allotting one-rib cuts of bone-in prime rib to two people will be sufficient for eight adults. This means that a four-bone roast, weighing over 8 pounds, or eight pounds of boneless ribs will be enough to feed everyone at your dinner party.

When it comes to cooking prime rib, it’s important to do it properly to bring out the best flavors. Use a reliable meat thermometer, like the ThermoPro TP19H Digital Meat Thermometer, to monitor the internal temperature and ensure it’s cooked to perfection.

Additionally, if you want to support local businesses and get higher quality meat, consider buying prime rib from your local butcher. They often have ethical and greener options, and may even offer better deals than supermarkets.

Happy cooking and enjoy your delicious prime rib dinner!

Quantity for 15 Adults

For a dinner party with 15 adults, it is recommended to have at least 16 pounds of bone-in cuts or 15 pounds of boneless rib cuts. When calculating prime rib serving size, it’s important to consider that guests should consume at least half a pound per person at a typical holiday dinner. As a main course, boneless cuts should weigh one pound per person. For famished guests, serving one rib cut per person is a generous option.

To cook prime rib perfectly, there are a few tips to keep in mind. First, research and practice different cooking techniques to find the one that suits your taste. Use a reliable meat thermometer, like the ThermoPro TP19H Digital Meat Thermometer, to monitor the internal temperature and ensure it reaches the desired level of doneness. Remember that cooking prime rib is a delicate process that requires careful attention.

By following these guidelines, you can ensure that your dinner party with 15 adults will be a memorable and satisfying experience.

Quantity for 10 Adults

To serve 10 adults, you’ll need ten pounds of bone-in or boneless prime rib. Both options will satisfy your hungry guests. Here are some tips to ensure your prime rib turns out perfect:

  1. Different cooking methods for prime rib:
  • Slow roast at a low temperature for even cooking and a tender, juicy result.
  • Try searing the prime rib before roasting to lock in flavors and create a delicious crust.
  1. Tips for seasoning and marinating prime rib:
  • Keep it simple with just salt and pepper for a classic taste, or try a flavorful rub or marinade to enhance flavors.
  • Let the prime rib sit at room temperature for about an hour before cooking to allow the seasoning to penetrate the meat.

With these tips in mind, your prime rib will be the star of your dinner party. Your guests will be satisfied and coming back for more.

Bone-in or Boneless

When it comes to choosing between bone-in or boneless prime rib, I prefer the juicier and more flavorful option of bone-in cuts. There’s something special about sinking my teeth into a succulent piece of meat that has been cooked with the bones intact. The bones not only add flavor, but they also help to retain moisture, resulting in a tender and moist prime rib.

However, boneless prime ribs have their advantages too. They have more flesh meat per pound, making them a good option if you prefer more meat and less bone. Additionally, boneless cuts are easier to carve and serve.

Ultimately, the choice between bone-in and boneless prime rib comes down to personal preference. For me, the added flavor and juiciness of bone-in cuts make them the clear winner.

Where to Buy

I usually prefer to buy prime ribs from local butcher shops because they offer higher quality meat and better service. There’s something special about walking into a traditional butcher shop and being greeted by friendly experts who are passionate about their craft. Not only do they provide top-notch meat, but they also offer ethical options, ensuring that the meat comes from sustainable sources.

But if you’re looking for a wider variety of prime ribs, online shops are a great option. They provide a plethora of choices, from different cuts to various seasoning options. You can explore different suppliers and find exactly what you’re looking for. However, it’s important to note that online shopping for prime ribs can be costly, especially when you factor in additional shipping costs.

So, whether you choose to support your local butcher or explore the online variety, you can rest assured that you’ll find the perfect prime rib for your dinner party.


Buying prime ribs can be expensive, with prices typically around $12 per pound. However, there are ways to find discounted prime rib and save some money without compromising on quality.

When it comes to prime rib pricing comparison, supermarkets usually offer good quality products at affordable prices. They often have sales and discounts, especially during holiday seasons, making it a great option for budget-conscious shoppers.

Another option is to check out local butcher shops, which may charge a bit more but often offer higher quality meat and better deals.

If you’re open to online shopping, there are also online shops that provide a wide variety of prime ribs, although they may come with additional shipping costs.

So, whether you choose to go the traditional route or explore online options, there are plenty of places to find prime rib at a reasonable price.
