A rich and hearty slow cooker oxtail soup recipe made with tender shredded beef, red wine, aromatic vegetables and herbs. This British classic is low-cooked for 8 hours, with the vegetables blended into the stock for a beautifully thick, smooth soup packed with deep beefy flavour.
Peel and finely chop the onion, carrot and celery.
Pat the oxtail dry with kitchen paper, then place in a bowl with the plain flour, salt and black pepper. Toss until evenly coated.
Heat the Wagyu beef dripping in a frying pan over a medium heat. Brown the oxtail pieces until caramelised on all sides, working in batches if necessary. Transfer to the slow cooker.
Add the chopped onion, celery and carrot to the same frying pan, adding more dripping if required. Cook for approximately 10 minutes until softened.
Stir in the tomato purée and apple cider vinegar and cook for 2 minutes.
Pour in the red wine and simmer until reduced by approximately half. Transfer the vegetables and reduced wine to the slow cooker.
Add the beef stock, rosemary, thyme and bay leaf. Cover and cook on LOW for approximately 8 hours, or until the oxtail is tender and the meat pulls away easily from the bones.
Carefully remove the oxtail pieces and allow them to cool enough to handle. Separate the meat from the bones and fat, shredding it into bite-sized pieces.
Remove excess fat from the cooking liquid by skimming the surface, or preferably by cooling and refrigerating the stock and vegetables until the fat solidifies and can be easily removed.
Remove the herb stalks and bay leaf. Check the stock and vegetables carefully for any bones or fragments, then blend until smooth using a hand blender or food processor.
Stir the shredded oxtail meat back through the blended soup and reheat until piping hot. Serve with freshly chopped parsley.
Notes
Oxtail: Oxtail contains plenty of bones, fat and connective tissue. Once cooked, carefully separate the meat fro the fat and check for small bone fragments before blending.Beef Dripping: I use Wagyu beef dripping for browning, but regular beef dripping (tallow) or another suitable cooking fat can be substituted.Red Wine: Reduce the wine by approximately half before adding it to the slow cooker to concentrate the flavour.Cooking Time: Cook on LOW for approximately 8 hours, or until the meat pulls away easily from the bones. Larger pieces may require additional cooking time.Removing Fat: My preferred method is to refrigerate the cooked stock and vegetables overnight, allowing the fat to solidify on the surface so it can be easily removed.Consistency: The soup is naturally thickened by blending the slow-cooked vegetables into the stock. Add a splash of beef stock or water if you prefer a thinner consistency.Storage: Refrigerate promptly in an airtight container for up to 4 days. The soup can be frozen for up to 4 months.Freezing: Freeze for up to 3 months for best quality. Defrost thoroughly in the fridge before reheating until piping hot.
