Important Factors to Consider to Determine How Much Meat to Buy Per Person for BBQs

As a general rule, we recommend allocating 8 to 12 ounces of raw meat per adult at BBQ, and about 4 to 6 ounces per child. This can be adjusted either up or down depending on many factors, so ask yourself the questions below to determine whether to serve more or less.

Serve more than 8 ounces for adults (or 4 ounces for kids) if you answer yes to any of these questions:

• I am planning to serve 2 or fewer side dishes.
• Meat is going to basically make up the entire meal (meaning there are few, if any, appetizers or desserts).
• The side dishes are mainly light, such as fruit salads or green salads.
• I love leftovers or plan to share them with guests.
• Most guests didn't eat a large meal earlier in the day.
• I am serving alcohol. (This tends to crank up guests' appetites.)
• My guests enjoy very generous portions.
• Most cuts of meat I'm cooking will not be served in a bun.

How Much Meat to Prepare Per Person For BBQ Meals

Keep in mind that most meats lose between 15% and 45% of their weight when they are cooked. (A half-pound ground beef burger, for example, will likely weigh just shy of 7 ounces after you grill or smoke it.) That's because cooking causes animal protein to lose some moisture and fat. The difference between the weight of cooked food and the weight of raw meat is called a "yield."
