Tender pork ribs are seasoned with a savory rub, pre-baked for rich color, then slow-cooked until juicy and finished with a sticky, caramelized barbecue sauce glaze.
Heat the oven to 400 °F. Have a large baking sheet ready with foil or parchment paper so the ribs can go straight into the oven.
Season both sides of the pork ribs with salt and freshly ground black pepper, then rub in the garlic powder, onion powder, and light brown sugar. The surface should look evenly coated, with no large patches of bare meat.
Place the seasoned ribs on the lined baking sheet and bake for 15 minutes, then turn them over and bake for 15 minutes more. The pork should sizzle lightly and develop early browning around the edges.
Curve the rack around the inside wall of the slow cooker with the meat facing outward, then coat it with barbecue sauce while reserving some for serving. Cover and cook on LOW for 4 to 6 hours, until the meat is tender and has pulled back from the bone tips.
Serve the ribs warm with the reserved barbecue sauce spooned over the top. The pork should bend easily when lifted but still hold together for slicing.
Notes
Membrane removal: Peel off the thin, papery membrane on the back of the bones using a dry paper towel for a secure grip. This prevents a chewy texture and lets seasonings penetrate the pork.Pot arrangement: Curve the rack around the slow cooker wall with the meat facing outward toward the ceramic heating surface for even cooking without sitting in excess diluted liquid.Broiler finish: For a caramelized exterior, brush the cooked ribs with extra sauce and broil 6 inches from the heat element for 3 to 5 minutes until bubbling and shiny.Reheating: Wrap leftover portions in foil with a spoonful of barbecue sauce and warm gently in the oven rather than microwaving to prevent rubbery meat.Nutrition information is an estimate based on common ingredients and serving sizes.
