To cook spare ribs in the oven, they are rubbed with seasoning, placed meaty side down in a baking dish and covered with foil. The ribs are baked at 225 degrees Fahrenheit for three to four hours. They can be covered with barbecue sauce or eaten plain.
The most basic recipe for cooking ribs in an oven is to sprinkle them with 2 teaspoons of salt and baste them with melted butter before placing them meat side down in a baking dish, covering the dish with foil and cooking the ribs at 225 degrees Fahrenheit between three and four hours. The ribs should be basted every half hour with more melted butter.
When the ribs are finished cooking, the drippings should be drained and the ribs turned meat side up. The ribs are returned to the oven, uncovered, for 30 to 40 minutes. For barbecue ribs, the ribs are covered with barbecue sauce prior to them being returned to the oven.
A Hawaiian themed recipe calls for the ribs to be basted with pineapple juice in place of butter, and an Asian inspired recipe for oven baked ribs uses teriyaki sauce for basting. A dry rub method uses a rub and increases the temperature to 300 degrees Fahrenheit. Using a dry rub method reduces the cooking time to three hours.
