Place the seasoned ribs on a large lipped baking sheet and cook in the oven for 15 minutes. Flip and bake for another 15 minutes. When the meat is ready, remove from the oven and discard any grease.
Place the ribs into your Slow cooker (try curling the ribs around it, meat side facing out). Pour the KC Masterpiece® sauce over top and cook on low for 6-8 hours.
Serve warm with extra KC Masterpiece® sauce.
