Roast Beef for a Crowd

Two decisions decide this: which roast, and how much. Both are easier than the cooking, and both get made badly.

Two decisions, and the cooking is the easy part of the evening.

How much to buy

Roast beef per person

Planning estimates. Round up; cold roast beef is never a problem.

Boneless roast, part of a big spread
About 1/3 lb per person. Right when there are two other mains and a lot of sides.
Boneless roast, the main event
About 1/2 lb per person. The standard case.
Bone-in roast
About 3/4 lb per person, because a meaningful share of that weight is bone.
You want leftovers
Add 1/4 lb per person on top. Sandwiches the next day are half the point of a big roast.

Which roast

  • Bone-in standing rib. The occasion roast. Most forgiving, best looking, most expensive. See standing rib against prime rib.
  • Sirloin tip. Much leaner and much cheaper. Roast it to medium rare and no further, and slice it thin.
  • Chuck. Not a roast in this sense. It wants braising for hours, which is a different and excellent dinner.

β€œYou think more farms should adopt knowing your numbers, managing your farm, like a business.”

Gray Shipley

The part that actually goes wrong

Carving. A roast that rested properly and then got carved with the grain eats dry, and everyone blames the cooking. Find the grain before the first slice, and if it changes direction partway through the roast, turn it. The mechanism is in why is my roast dry.

β€œWhen people come to the farm, I got a friend from college who visited the farm, known him for 25 years. And he told me that now I get it. Just seeing it and getting to understand and experience the place gives people, I think, a lifetime connection that they want to share with others.”

Gray Shipley

β€œAnd when a kid comes onto a farm and gets to just get out into nature, see them kind of come alive a little bit, especially if it's something that they hadn't really encountered before.”

Bone-in, dry-aged, and the most forgiving thing you can put in front of twelve people.

Common question

What beef should I roast for a large group, and how much?

A bone-in rib roast or a sirloin tip, and about half a pound of boneless weight per person.

Every quote on this page is Gray Shipley talking, the man who runs this farm. We sat down with him, turned on a recorder, and kept his own words. Hesitations are trimmed so they read on the page. Nothing else is added or reworded, except where Gray revised his own words in review.

Nobody knows this beef better than we do. On food safety we leave it to USDA FSIS and FoodSafety.gov, and we have linked their pages above. Reviewed 3 October 2026.
