What Are Baby Back Ribs?

Baby back ribs come from the upper part of the ribcage, near the spine, and are taken after the loin has been removed. They’re typically smaller, curved, and more tender than other rib cuts. Their name can be a bit misleading—they don’t actually come from baby pigs but refer to the size and location of the cut.

These ribs have less fat and connective tissue, making them ideal for quicker cooking methods like grilling or baking. However, they still benefit greatly from low-and-slow smoking to enhance their tenderness and depth of flavor.

What Are St. Louis Ribs?

St. Louis ribs, on the other hand, come from the lower belly side of the pig, just below where baby backs are found. These ribs are trimmed to remove the sternum bone, cartilage, and excess fat, resulting in a flatter, more uniform rack that’s easier to cook evenly.

Known for being meatier and fattier, St. Louis ribs offer a richer flavor profile and are perfect for slow-smoking techniques. They’re also often considered the go-to choice for classic American barbecue due to their ability to absorb smoke and spices beautifully.

How to Cook Each Cut Like a Pro

Let’s get down to the fun part—cooking! Each type of rib has its own sweet spot when it comes to preparation and method. Here's how to nail each one:

Baby Back Ribs Recipe

• Step 1: Remove the membrane from the bone side for better seasoning penetration.
• Step 2: Season generously with a rub (we love a blend of paprika, brown sugar, garlic powder, and cayenne).
• Step 3: Smoke at 225°F for 2.5–3 hours or grill over indirect heat.
• Step 4: Optional: Wrap in foil with apple juice halfway through cooking.
• Step 5: Finish with a brush of barbecue sauce and a quick sear over high heat.

St. Louis Ribs Recipe

• Step 1: Trim any excess fat for even cooking.
• Step 2: Apply a bold dry rub (try chili powder, cumin, black pepper, and a touch of coffee for complexity).
• Step 3: Smoke low and slow at 225°F for 5–6 hours.
• Step 4: Wrap in foil once the bark forms to retain moisture.
• Step 5: Unwrap, glaze with sauce, and finish on the grill for a caramelized crust.

Buying Guide: Choosing the Right Ribs for You

Shopping for ribs can be confusing if you’re not sure what to look for. Here’s your ultimate guide to picking the perfect slab:

Look For These Features:

• Color: Look for bright pink or red hues; avoid gray or dull-colored ribs.
• Fat Distribution: A nice layer of fat means more flavor—don’t go too lean!
• Uniformity: Racks should be consistent in thickness and spacing for even cooking.
• Marbling: Especially important for St. Louis ribs; marbled meat equals juiciness.
