Garlic Herb BBQ Spare Ribs: Slow-Cooker Pull-Apart Step-by-step instructions

Before you start

Before you start, gather all your ingredients and equipment. The ribs should be at room temperature for about 30 minutes before cooking, but no longer. Pat them dry with paper towels to help the sauce adhere. Smash the garlic cloves with the flat side of a knife to release their oils.

Rinse the rosemary sprigs and pat them dry. Measure out the barbecue sauce. Have your slow cooker ready—no need to preheat it. This recipe requires no prep beyond these simple steps, so you can have everything ready in 10 minutes.

Instructions

Layer and Sauce

1. 1Layer the Ribs and Aromatics
   Place the two racks of St. Louis style pork spare ribs into the slow cooker, meaty side up. Scatter the smashed garlic cloves and fresh rosemary sprigs evenly over the ribs.
   Look for The ribs should fit in a single layer, slightly overlapping if needed. Garlic and rosemary should be scattered across the surface.
   Tip If the racks are too long, cut each rack in half to fit comfortably.
2. 2Pour the BBQ Sauce Over
   Pour the thick Kansas City barbecue sauce over the ribs, using a spatula to spread it evenly, ensuring the top surfaces are coated. Do not stir; the sauce will meld during cooking.
   Look for The ribs are covered in a glossy, thick layer of sauce. Some sauce pools around the edges.
   Tip For extra coverage, brush sauce onto the sides of the ribs with a basting brush.
3. 3Cover and Cook Low
   Cover the slow cooker with the lid. Cook on low for 8 hours, or until the meat is fork-tender and easily pulls away from the bone. Do not open the lid during the first 6 hours to maintain steady heat. Let it rest for 3 minutes before slicing.
   Look for After 8 hours, the meat should be very tender; a fork inserted into the thickest part twists easily with little resistance.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip If using a programmable slow cooker, set it to low and keep warm after the cooking time ends.

The slow cooker contains the ribs, garlic, rosemary, and barbecue sauce. The ribs are coated in a thick, glossy layer of sauce. The garlic and rosemary are scattered across the top, and the sauce pools around the edges. The aroma is sweet, smoky, and herbal. The slow cooker is covered and set to low.

Slow-Cook and Tenderize

4. 4Check for Doneness
   Uncover the slow cooker and check that the ribs have reached an internal temperature of at least 145°F (63°C) for food safety, though they will be much higher after slow cooking. The meat should be pull-apart tender and nearly falling off the bone. Let it rest for 3 minutes before slicing.
   Look for The meat is deeply browned, glistening with sauce, and the bones are exposed in places. A fork pierces with no resistance.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip If the ribs are not yet fork-tender, cover and continue cooking for another 30–60 minutes.
5. 5Rest the Ribs
   Turn off the slow cooker and let the ribs rest in the sauce for at least 3 minutes before serving. This allows the juices to redistribute and the meat to firm slightly for easier handling.
   Look for The sauce has settled slightly, and the ribs look moist and glistening.
   Tip Use this time to warm serving plates, if desired.

After 8 hours, the kitchen smells intensely of barbecue and herbs. The sauce is bubbling gently around the edges. The ribs are visibly shrunken, and the meat is pulling back from the bones.

A fork inserted into the thickest part twists easily, and the meat shreds with minimal effort. The sauce has thickened and darkened.

Serve with Sauce

6. 6Lift and Serve
   Using a carving fork, carefully lift the ribs from the slow cooker, letting excess sauce drip back. Transfer to a cutting board or serving plate. Use a spoon to drizzle additional sauce from the cooker over the ribs.
   Look for The ribs are tender enough that they may sag slightly when lifted; a fork holds them securely.
   Tip For clean slices, let the ribs rest for 5 minutes before cutting between the bones.
7. 7Spoon Sauce and Serve
   Spoon the garlicky, rosemary-infused sauce from the slow cooker over the ribs. Serve hot, with extra sauce on the side if desired.
   Look for The sauce is thick, glossy, and flecked with softened garlic and rosemary leaves.
   Tip The garlic cloves become sweet and spreadable; serve them alongside the ribs.

The ribs are lifted from the slow cooker, glistening with a sticky, mahogany sauce. The meat is so tender it nearly slips off the bone. The garlic cloves are soft and golden, and the rosemary leaves are fragrant. A final spoonful of sauce is drizzled over the top before serving.

Common mistakes

One common mistake is lifting the lid during cooking, which lets out heat and extends cooking time. Trust the process and keep the lid on. Another is using a thin barbecue sauce that does not cling; if your sauce is thin, you can simmer it on the stovetop to thicken before using.

Overcooking can lead to mushy ribs, but with a slow cooker on low, this is unlikely if you stick to the time. Finally, don't skip the rest—this allows the juices to redistribute and makes the ribs easier to handle.

How to tell it’s done

The ribs are done when they are pull-apart tender. Use a fork to test: insert it into the thickest part of the meat and twist. The fork should go in with almost no resistance, and the meat should separate easily.

The internal temperature should be at least 145°F (63°C) for food safety, but it will likely be much higher—around 190°F to 200°F—which is ideal for breaking down collagen. The meat will be deeply browned, and the bones may be slightly exposed. The sauce should be thick and glossy, not watery.
