Fall-off-the-bone slow-cooker BBQ ribs coated in smoky sauce are a family favorite that requires minimal effort. These protein-packed ribs are perfect for busy weekends when you want big flavor without the fuss.
Peel and slice the onion into thick rings and layer them on the bottom of the slow cooker to prevent ribs from sticking and provide flavor.
Remove the thin membrane from the back of the ribs for more tender results. Pat ribs dry with paper towels.
Mix together brown sugar, smoked paprika, garlic powder, salt, and black pepper. Rub this spice blend evenly over both sides of the ribs.
Cut the ribs into 2-3 rib sections to fit in the slow cooker. Place them over the onions in layers.
Pour 1 cup of the BBQ sauce evenly over the ribs, reserving the remaining sauce for finishing. Cover and cook on LOW for 6–8 hours, or until the ribs are very tender and nearly fall off the bone.
Carefully remove ribs from the slow cooker and arrange on a foil-lined baking sheet. Brush with the remaining BBQ sauce.
Broil in the oven on high for 3–5 minutes, watching closely, until the surface caramelizes for a sticky, smoky finish. Serve warm.
