Prepare the Ribs:
Remove the membrane from the back of the ribs by sliding a knife under it and pulling it off. This step ensures the ribs cook evenly and become more tender.
Cut the ribs into sections that fit into your crock pot, usually 2–3 ribs per section.
Season the Ribs:
In a small mixing bowl, combine smoked paprika, garlic powder, onion powder, black pepper, salt, and cayenne pepper.
Rub the spice mixture generously over both sides of the ribs.
Set Up the Crock Pot:
Place the ribs in the crock pot, standing them upright along the edges to maximize space.
Pour the apple cider vinegar into the bottom of the crock pot. This helps tenderize the meat as it cooks.
Slow Cook the Ribs:
Cover and cook on low for 7–8 hours or on high for 4–5 hours, until the ribs are tender and the meat is nearly falling off the bone.
Add Barbecue Sauce:
Once the ribs are cooked, carefully remove them from the crock pot and place them on a baking sheet lined with aluminum foil.
Brush barbecue sauce generously over the ribs.
Optional Finish in the Oven:
For a caramelized, sticky glaze, broil the ribs in the oven on high for 3–5 minutes, watching closely to avoid burning.
Serve:
Serve the ribs warm with extra barbecue sauce on the side. Pair with classic sides like coleslaw, cornbread, or baked beans for a complete meal.
