spare ribs vs baby back ribs: what is the difference?

Summer is coming and that means it’s barbecue season—and there’s no better time to finally figure out the difference between baby back and spare ribs than the present.

Pork ribs go by many names, depending on the region, but two of the most common in American BBQ are baby back ribs and spare ribs.

Baby Back Ribs

Baby back ribs, also known as back ribs, loin ribs, or Canadian back ribs, are shorter than spare ribs and a full slab has between 11 and 13 bones. Baby back ribs are connected to the backbone and nestled beneath the loin muscle—they get their name from the fact that they’re the most tender and leanest ribs. They’re sometimes called Canadian ribs because Canadian bacon is made from the same loin mean that’s connected to the ribs. (If you want to learn more than you bargained for about different cuts of pork, check out this very detailed and informative diagram.)

Spare Ribs

Spare ribs, also known as St. Louis cut ribs or Kansas City cut, are a flatter, rectangular slab that aren’t as curved as baby back ribs. Spare ribs can be less expensive because they contain more bone and aren’t always in as high demand as baby back ribs. Spare ribs are about three pounds and usually a rack will feed about two people (much of the weight is from the heavy bones). The meat is very flavorful; spare ribs are cut from the end of the baby back ribs, and they’re often meatier than baby back ribs. St. Louis cut ribs are simply spare ribs with the rib tips cut off so that the whole package is a neat rectangular slab.
