What Are St. Louis Ribs Anyway?

If you’ve ever tried a rack of ribs that was meaty, flat, and shaped kind of like a football field, congrats — you’ve met St. Louis ribs.

St. Louis-style ribs come from the pig's ribcage, specifically the portion known as the spare ribs. But unlike typical spare ribs, which have a more irregular shape, St. Louis ribs are trimmed down into a neat, rectangular shape by removing the sternum bone, cartilage, and rib tips.

This trimming makes them cook more evenly and gives them that iconic look that says, “I mean business when it comes to flavor.”

The Difference Between St. Louis Ribs and Baby Back Ribs

Feature	St. Louis Ribs	Baby Back Ribs
Source	Spare ribs (from belly side)	From the loin (back of pig)
Texture	Fattier, more marbled	Leaner, tender
Cooking Time	Longer due to density	Shorter, quicker to cook
Flavor	Rich, bold, smoky	Mild, delicate

So... Are St. Louis Ribs Pork or Beef?

Let’s settle this once and for all:

Yes, St. Louis ribs are made from pork — not beef.

They come from the pig’s rib section and are typically classified under spare ribs. The confusion may stem from the fact that some restaurants or grocery stores label different cuts ambiguously, but in traditional barbecue terminology, St. Louis ribs are 100% pork-based.

Beef ribs do exist — like beef short ribs — but those are usually labeled separately. So if you see “St. Louis ribs” on a menu, rest assured you’re getting a delicious, fatty cut of pork that’s perfect for slow-smoking and heavy seasoning.

Spice It Up: Rubs That Make These Ribs Unforgettable

Now that we’ve confirmed St. Louis ribs are pork, let’s talk about how to season them right. Because what separates a decent rack from a drool-worthy masterpiece is often just a handful of spices.

Essential Spices for St. Louis Rib Rubs

• Paprika – Adds color and mild sweetness
• Brown Sugar – Balances salt and adds caramelization
• Garlic Powder – For that deep umami kick
• Onion Powder – Enhances overall savory depth
• Black Pepper – Brings subtle heat
• Chili Powder / Cayenne – Optional, for spice lovers
• Salt – Essential for drawing out moisture and enhancing flavor

Pro Tip: Use a 3-2-1 Rule for Balanced Flavor

• 3 parts brown sugar
• 2 parts paprika
• 1 part salt + garlic/onion powder

This simple ratio gives you that sweet-smoky-salty combo that keeps people coming back for more. And remember — don’t be shy! You should coat the ribs liberally and then let them rest for at least an hour (or ideally overnight) in the fridge before cooking.
