Slow Cook Ribs In Oven 275 Degrees. Slow cooking ribs in the oven Once the ribs have been prepared for slow cooking set your oven temperature to 275 degrees. Bake in preheated oven until tender 2 12 to 3 hours.
After two hours place each rack of ribs individually BONE SIDE UP on separate large sheets of tin foil and wrap tightly no leaks. Bake ribs meaty side up in the oven for 2 to 25 hours uncovered. About 30 minutes before the end of cooking brush the ribs with barbecue sauce.
Remove from oven and unwrap ribs.
How long should you cook ribs at 300 degrees. On top of this I let them sit for 30 minutes or an hour after. At 170 to 180 degrees the meat is noticeably dryer but the cooking time is a more manageable 6 to 8 hours. About 30 minutes before the end of cooking brush the ribs with barbecue sauce.
