Spare Ribs Overview
“It’s important to note that we did not become rib masters overnight. It took time to learn the appropriate techniques. Tender, slow-cooked spare ribs require a certain amount of skill and experience.” — Pat Neely
Well, that’s why we’re all here, right? To learn how to make incredible ribs. No, it won’t happen the first time. But it will happen, and what a day that is!
Now, despite the big build-up in the introduction, it turns out spare ribs and St. Louis style ribs are basically the same thing. St. Louis ribs are, in fact, cut from the spares, so they share many characteristics.
From this information, we can conclude that a rack of spare ribs is larger than a rack of St. Louis. Incidentally, if you’ve seen or heard reference to “side ribs,” it’s just another term for spare ribs.
Spare ribs aren’t the most tender cut of meat, being so far from the loin. But, that’s where the magic of smoking comes in. Smoking them low ‘n’ slow makes them easy to eat and unleashes a ton of rich flavor.
Spare ribs are popular throughout most of the world, and you see a lot of them at ribfests and competitions.
Where on the Pig They Come from
Spare ribs are cut from the end portion of the rib cage, right down at the belly of the pig. They extend around the side of the pig and down to the breastbone, which the butcher removes.
They’re long ribs, and they come to a ragged end of extra meat and cartilage. Plus, spare ribs sport a bonus flap of meat called the skirt. A typical rack of spare ribs totals 11 bones.
How Much Meat and Fat do They Contain?
As mentioned above, there is a lot of meat on spare ribs, making them an ideal choice for parties and large crowds. They’re also blessed with a lot of fat. If fat doesn’t seem to you like a blessing, remember that fat equals flavor when it comes to meat.

Portion Size: How Many Spare Rib Ribs Per Person
A rack of spare ribs is physically large, but there aren’t a lot of bones. Plan on 4-5 bones per lucky person at your barbecue.
How to Prepare Spare Ribs for Smoking
Don’t be tempted to put an untrimmed rack of spare ribs in your smoker. While there may be a sense of primal delight, a little prep goes a long way.
To prevent unwanted chunks of burnt crud, trim any big flaps and nodules of fat and random sinew. Don’t worry, though — there will still be plenty of fat for flavor and juiciness.
More than likely, your spare ribs will come with a thin but shockingly resilient membrane attached to the bone side of the rack. Before you continue, this has got to go. Yes, you can cook with it in place, but you’re just passing the job off to your guests, who will have to gnaw through it. Strip it away, and you’ll also get deeper, more even penetration of smoke, rub, and sauce.
Begin with a sharp paring knife. Slip the blade between one of the outside bones and the membrane and, with short, careful strokes, begin separating the two. Mind you don’t cut any meat off the ribs or your fingers. Soon, you’ll have a flap of membrane large enough to get hold of with your hands. Grab it, and peel away the membrane, hopefully in a single sheet. Find more detailed instructions with images in our guide on how to remove the membrane from ribs.
If your recipe calls for marinade or brine, do it now. Allow several hours for liquids to soak in, or you may as well not bother. If you can leave it all night, that’s usually ideal. Once that process is over, you can massage in your spice rub before moving to the smoker.
How to Cook Spare Ribs in a Smoker
The preferred temperature for smoking spare ribs is 250 °F. Yes, that’s the high-end of the low ‘n’ slow zone, but it’s suitable for such thick and large ribs. It’s still going to take the best part of the daylight hours to get the job done!
There are lots of wood choices available to the smoker, but not all them are suited to ribs. Most Midwestern and southern recipes will call for mesquite or hickory. Fans of sweet BBQ flavors will want to try cherry or applewood. Oak is fine, but it’s a little too safe for our liking.
Next comes the old question: do I wrap my ribs or not? The answer to that is yes — probably.
It’s preferred by most pitmasters and barbecuers as it helps prevent ribs from losing their moisture while locking in the flavor. You can opt not to wrap your ribs, but you may find them a little drier that way. Still, it’s all a matter of personal preference.
If you’re using the famous 3-2-1 method to smoke your spare ribs, you’ll certainly wrap your ribs; it’s the “2” part of the system. If you’re not familiar with it, 3-2-1 works like this: smoke unwrapped at your target temperature for 3 hours, switch to wrapped for 2 hours, and then close it out with 1 hour unwrapped over higher heat. That’s the perfect combination for smokiness, juiciness, and crispy bark.
Apply your sauce, if you’ve decided to use any, during the last 30 minutes of the session. You risk burning it any longer, which is easy to do because most BBQ sauces are sugar-based.
Cook your spare ribs until they reach an internal temperature of about 190 °F – 200 °F. You’ll know it’s about that time when you start seeing exposed bones as the meat contracts, the meat is probe tender, and if you pick up the ribs with tongs, it will bend and start to crack slightly.
Where to Buy Spare Ribs Online
Snake River Farms’ spare ribs are from purebred Berkshire, their American Kurobuta range.
They are all-natural and hormone-free, full-sized, with abundant flesh and superb marbling and intramuscular fat for a rich and fulfilling taste. Each rack weighs about 1.5 pounds on average.
St. Louis Ribs Overview
St. Louis style ribs are a neatly trimmed section of the larger spare ribs as touched on earlier. This cut came into existence sometime in the middle of the last century in -you guessed it- St. Louis, Missouri.
The butcher or meat packer removes the spare ribs’ irregular ends, called the rib tips, and generally cleans the rack up into a good-looking rectangle of ribs. While they’re shorter than spares, St. Louis style ribs are longer than baby back ribs.
Where you see St. Louis ribs frequently is on the competition circuit. Pitmasters love the even cooking, straight bones, and neat presentation of the rack.
Where you won’t see St. Louis style ribs frequently is at the grocery store. If you want a rack, you’ll either have to trim your own spares (and we’ll tell you how a little further down) or get them from a proper butcher. You may need to custom order your rack.

How to Trim Spare Ribs to Become St Louis Cut
Time to let out your inner butcher! Here’s how to cut down those spares into DIY St. Louis ribs:
- Get a long, sharp knife you know can cut through cartilage and sinew.
- Turn the rack bone-side down and place it on a cutting board. Remove the narrow, pointed end of the rack. The ribs should now be roughly rectangular in shape across the ends and one side.
- Flip the rack over and find the flap of meat called the skirt. (It’s pretty easy to locate!) Cut this off and set aside; there’s good meat here, so you might want to cook it separately.
- Trim away any other obvious bits of fat and gristle. You want your rack to be as evenly shaped as possible.
- Remove the membrane as you would with a rack of spare ribs. We’ve described this process up above, in case you missed it.
- Find where the ribs end inside the meat. Use this line as a guide for cutting away the meat that extends past the end of the ribs. You should now have a fully rectangular rack of St. Louis style ribs.
Don’t discard the ends you cut off in the last step! These are called “rib tips”, and they’re fun to cook and eat on their own.
Why Bother Cutting St Louis Style? What are the Benefits?
So, if St. Louis style ribs are just spares trimmed a certain way, why go through the effort? Here are several good reasons.
- They just look better on the plate. If you think the presentation is part of the dining experience, you’ll appreciate how appealing St. Louis ribs look, especially in comparison to the full spare.
- On a technical note, the uniform shape of St. Louis style allows them to cook more evenly. You’ll get perfect doneness end-to-end and all the way through.
- They’re much easier to eat because you’ve removed the extra bone and connective tissue found at the rib tips.

Three Excellent Smoker Recipes for Spare or St. Louis Ribs from Around the Web
Got your ribs ready but not sure how you want them done? Here are three fantastic recipes for spare ribs you’re going to love.
Sweet Honey Lime Smoked Ribs
If you like your ribs on the sweet and tangy side, this is a recipe you need to try. Limes feature prominently in the rub and the sauce. There’s also a sizable dollop of honey for that sticky-sweet finish so many people love. Don’t worry if you like your seasonings, though; classic rub spices like cumin and paprika are also on the ingredients list.
Cherry or applewood is recommended for this recipe. That makes sense; the sweet smoke from the fruit wood will complement the sauce beautifully. You’ll need to apply sauce about a half-a-dozen times during the smoking, so if you were looking for a stick-them-in-and-walk-away recipe, this isn’t it. But, the end results will be worth the effort!

Mesquite Smoked BBQ Pork Ribs

Because you use pre-made BBQ sauce instead of making your own, you’ll not only save prep time, but you’ll also know exactly what it tastes like before you cook. No serving up an experiment!
The rub is packed with traditional spices, including smoked paprika and cumin. It also features ancho chili powder instead of regular chili powder; ancho delivers tons of distinct flavor, but with only a tiny bit of heat.

Smoked Mustard Crust Spare Ribs
A tasty crust of grainy mustard is something normally associated with pork shoulders. But, why shouldn’t ribs get the same special treatment?
