Low and Slow. Spare ribs, like any tough cut of meat, need slow cooking at low temperatures to become tender and juicy. Set them on a baking rack placed on a baking sheet and bake them at 300 degrees Fahrenheit for 1 1/2 to 2 hours.You can cook the ribs uncovered, or pour a bit of apple juice in the pan and cover the ribs with aluminum foil.assage this mixture into the meat before cooking. As the ribs bake, you can add additional flavor in several ways. Baste the ribs occasionally with a mopping sauce, which is simply watered down barbecue sauce, or brush the ribs during the last 30 minutes of cooking with a mixture of melted butter and liquid smoke.
