These Smoked St. Louis Spare Ribs are tender, juicy, smoky, and perfect for summer cookouts. Use the classic 3-2-1 method for fall-off-the-bone ribs, or shorten the wrap time for ribs with more bite.
Prep the ribs: Pat the ribs dry with paper towels. Remove the membrane from the back of the ribs by loosening one corner with a knife, then gripping it with a paper towel and pulling it away.
Season the ribs: Coat both sides of the ribs generously with barbecue dry rub. For the best flavor, refrigerate the ribs overnight, then add a light dusting of rub before smoking.
Preheat the smoker: Preheat your smoker to 225°F to 250°F. Add wood chunks, chips, or pellets according to your smoker setup.
Smoke unwrapped: Place the ribs on the smoker bone-side down. Smoke for 3 hours, or until the rub is set and the ribs are a deep reddish-brown color.
Wrap the ribs: Place each rack on foil or butcher paper. Add apple juice, and if desired, butter, brown sugar, or extra rub. Wrap tightly and return to the smoker.
Cook wrapped: Cook wrapped for 1 to 2 hours. Use 2 hours for fall-off-the-bone ribs or closer to 1 hour for bite-through ribs.
Unwrap and sauce: Carefully unwrap the ribs and return them to the smoker. Brush with barbecue sauce if desired.
Finish the ribs: Cook for about 1 more hour, until the sauce is set and the ribs are tender. The ribs are usually done around 190°F to 203°F, depending on your preferred texture.
Rest and serve: Let the ribs rest for 10 to 15 minutes, then slice between the bones and serve.
Notes
St. Louis ribs are spare ribs that have been trimmed into an even rectangular shape.
The 3-2-1 method gives softer, fall-off-the-bone ribs.
For ribs with more bite, shorten the wrapped stage to about 1 hour.
Temperature is a guide. Ribs are done when they bend easily, the meat pulls back from the bones, and a probe slides in with little resistance.
Hickory, apple, cherry, oak, and pecan are all good woods for ribs.
Store leftovers in the refrigerator for 3 to 4 days.
