St. Louis Ribs Full Rack Recipe

Trim and remove membrane

If your butcher hasn’t already, trim excess fat and square the rack. On the bone side, slide a butter knife under the silver membrane at one end, loosen it, then grab with paper towel and pull to remove the membrane completely. Removing the membrane helps seasonings penetrate and yields more tender ribs.

Apply binder

Pat the ribs dry with paper towels. Lightly coat both sides of the rack with yellow mustard (about 2 tbs) — this acts as a binder for the dry rub and won’t impart a noticeable mustard flavor after cooking.

Make the rub

In a bowl, combine brown sugar, paprika, kosher salt, black pepper, garlic powder, onion powder, chili powder, and cayenne. Mix until evenly distributed.

Apply rub

Generously coat both sides of the mustard-coated ribs with the dry rub, pressing it into the meat so it adheres. Use about three-quarters of the rub on the top (meaty side) and the rest on the bone side. Let the ribs rest at room temperature for 30 minutes or refrigerate covered for several hours or overnight for deeper flavor.

Preheat smoker

Prepare your smoker for indirect cooking and preheat to a steady 225°F (107°C). If using a charcoal/gas grill, set up for two-zone cooking with coals or burners off to one side and a drip pan on the other. Add wood chips or chunks (hickory, apple, or pecan) to produce smoke.

Smoke the ribs (Unwrapped phase)

Place ribs bone-side down on the smoker grates. Maintain smoker temperature at 225°F. Smoke for 3 hours uninterrupted, checking occasionally to ensure steady temperature and smoke. During this phase you want a thin, glossy bark to form and smoke flavor to penetrate.

Wrap with liquid

After 3 hours, transfer the ribs to a double sheet of heavy-duty aluminum foil (or two sheets layered) bone-side down. Sprinkle 1 cup apple juice evenly over the meat, then wrap tightly to create a sealed packet. This step speeds tenderization and keeps ribs moist.

Continue cooking wrapped

Place the wrapped ribs back on the smoker and cook for another 2 hours at 225°F. Internal meat should be very tender and beginning to pull away from the bone ends.

Unwrap and dry

Carefully open the foil packet (watch out for hot steam) and drain any excess liquid into a container. Pat the racks lightly with paper towel to remove excess moisture so the sauce will stick and caramelize.

Glaze and finish on smoker/grill

Mix the BBQ sauce with honey and apple cider vinegar. Brush a thin, even layer of the sauce mixture on both sides of the ribs. Return the unwrapped ribs to the smoker or a hot grill set to 275–300°F for 20–30 minutes, flipping and glazing once, until the sauce is tacky and slightly caramelized. Watch carefully to prevent burning.

Rest

Remove ribs from heat and let rest, uncovered, for 10–15 minutes. Resting lets juices redistribute and cools the surface so slices are neater.

Slice and serve

Using a sharp knife, slice between the bones to portion the ribs. Serve with extra warmed BBQ sauce on the side and classic sides (cole slaw, baked beans, cornbread) as desired.
