How many pounds of prime rib do you need per person (bone-in vs boneless)?

For bone-in standing rib roast, buy 1.0 to 1.25 lbs raw per person (or 1 bone for every 2 guests). For boneless rib roast, buy 0.75 to 1.0 lb raw per person.

How many people does a 3-bone or 4-bone standing rib roast feed?

A 3-bone roast (~6.0 to 7.5 lbs) comfortably feeds 6 adult guests. A 4-bone roast (~8.5 to 10.0 lbs) feeds 8 guests with generous portions.

What is a cradle-tied roast?

A cradle-tied roast is when the butcher cuts the rib bones away from the meat and ties them back on with kitchen twine. This provides all the flavor and moisture benefits of bone-in cooking while making tableside carving completely effortless.

What internal temperature should you pull prime rib for edge-to-edge medium-rare?

Pull prime rib at 120°F for Rare or 125°F for Medium-Rare. During the 30-minute rest, carryover cooking will raise the internal temperature an additional 5°F to a perfect 130°F–135°F.

Why is the reverse sear method superior to high-heat roasting for prime rib?

Reverse searing gently raises the meat temperature at 225°F, activating tenderizing enzymes and eliminating the wide gray overcooked outer ring, before finishing with a high-heat sear for an incredible crispy crust.

How much does a prime rib roast shrink during roasting and resting?

A standing rib roast loses roughly 15% of its total weight in evaporative moisture and rendered fat when reverse seared at low temperatures, compared to 25%+ shrinkage in traditional high-heat methods.
