A recipe on BettyCrocker.com for cooking beef ribs in a slow cooker involves browning the beef ribs in a skillet, transferring them to the slow cooker and adding some spices and broth. Cook the ribs on low until the meat is tender.
Heat 2 tablespoons of oil over medium heat in a skillet. Sprinkle 1/4 teaspoon of salt and 1/4 teaspoon of pepper over the beef ribs and brown them in the skillet. When they are brown, transfer them to the slow cooker.
Add 1/2 cup of chopped onions, 2 tablespoons of tomato paste and 1 tablespoon of Worcestershire sauce. Stir to blend and add 1/2 cup red wine and 1/2 cup of beef broth. If you omit the wine, add another 1/2 cup of beef broth in its place. Stir the contents of the slow cooker and add the browned ribs. Cover and cook on low for seven to nine hours or until the beef ribs are tender.
Remove the beef ribs and bones from the slow cooker. Skim off any fat and discard. In a small bowl, mix together 1/4 cup of water and 2 tablespoons of cornstarch until smooth. Add the mixture to the slow cooker and stir. Increase heat to high and cook for 10 to 15 minutes or until thickened. Serve gravy with the beef ribs.
