What You’ll Need

• 2-3 pounds oxtail, cut into pieces
• 1 medium butternut squash (about 2 pounds), peeled and cubed
• 1-2 large onions, chopped
• 2-3 carrots, sliced
• 2-3 celery stalks, chopped
• 4-5 garlic cloves, minced
• 2 tablespoons tomato paste (optional, for depth)
• 1-2 bay leaves
• 8-10 cups beef or chicken stock
• 1 teaspoon dried thyme (or a few sprigs fresh thyme)
• Salt and pepper, to taste
• 2 tablespoons vegetable oil
• Large Dutch oven, stock pot, or pressure cooker
• Slotted spoon and ladle
• Knife and cutting board

Step-by-Step

1. Prepare the ingredients. Cut the oxtail into pieces if not already done by the butcher. Peel and cube the butternut squash into 1-inch pieces. Chop the onions, carrots, celery, and mince the garlic.
2. Brown the oxtail. In a large Dutch oven or stock pot, heat the vegetable oil over medium-high heat. Add the oxtail pieces in batches, browning them on all sides (about 3-4 minutes per batch). Remove browned oxtail to a plate.
3. Sauté the aromatics. In the same pot, add chopped onions, carrots, celery, and a pinch of salt. Sauté for 5-7 minutes until softened. Add minced garlic and cook for another minute. Stir in the tomato paste if using, and cook for 1-2 minutes to caramelize.
4. Deglaze and return oxtail. Pour in a splash of stock and scrape up any browned bits from the bottom of the pot. Return the browned oxtail to the pot along with any juices.
5. Add stock and seasonings. Add the remaining stock to cover the oxtail by at least an inch. Add bay leaves and thyme. Bring to a simmer.
6. Simmer gently. Cover and simmer on low heat for 2.5 to 3 hours on the stovetop, or 1.5 to 2 hours in a pressure cooker. The oxtail should be very tender and the meat nearly falling off the bone.
7. Skim fat and impurities. Periodically skim off any foam or excess fat that rises to the surface during cooking. This keeps the broth clear and less greasy.
8. Add butternut squash. Once the oxtail is tender, add the cubed butternut squash. Simmer for another 20-30 minutes, or until the squash is fork-tender but not falling apart.
9. Adjust seasoning. Remove the bay leaves and thyme stems. Taste and adjust salt and pepper as needed.
10. Serve. Ladle the soup into bowls, making sure each serving gets some oxtail and squash. Garnish with fresh herbs if desired. Serve hot with crusty bread or rice.

Common Mistakes

• Undercooking the oxtail: Oxtail is tough and requires long, slow cooking to become tender. Rushing the process will result in chewy meat.
• Overcooking the squash: Adding butternut squash too early can cause it to disintegrate and lose texture. Always add it after the oxtail is tender.
• Not skimming fat: Oxtail is fatty. Skipping the skimming step can leave the soup greasy and heavy.
• Using too little liquid: The soup should be brothy. Insufficient liquid can cause it to burn or become too concentrated.
• Not seasoning gradually: Adding all salt at once can make the soup too salty, especially as it reduces. Taste and adjust at the end.

Tips

• For deeper flavor: Roast the oxtail pieces in the oven at 425°F (220°C) for 30 minutes before simmering. This intensifies the broth.
• Make ahead: Oxtail soup tastes even better the next day. Chill overnight, skim off solidified fat, and reheat gently.
• Pressure cooker shortcut: Use a pressure cooker to reduce oxtail cooking time to about 1.5 hours. Add squash only for the last 10-15 minutes under pressure or simmer uncovered after releasing pressure.
• Add greens: Stir in chopped kale, spinach, or Swiss chard just before serving for extra nutrition.
• Freeze leftovers: This soup freezes well for up to 3 months. Cool completely before transferring to freezer-safe containers.
• For a clearer broth: Strain the soup after cooking, then return solids to the clarified broth.

Troubleshooting

• Oxtail is still tough after hours: Keep simmering. Oxtail can take up to 4 hours if particularly large or meaty. Make sure you’re at a gentle simmer—not a boil, which can toughen meat.
• Squash is mushy: Next time, add squash later or cut into larger chunks. For now, you can puree some into the broth for a thicker texture and leave the rest as is.
• Soup is too greasy: Skim more fat from the surface with a spoon. If making ahead, chill and remove the hardened fat cap before reheating.
• Soup is bland: Add a splash of soy sauce, Worcestershire, or a squeeze of lemon juice to brighten flavors. Adjust salt gradually.
• Soup too thick: Add more stock or water, a half-cup at a time, until desired consistency is reached. Taste and adjust seasoning after diluting.
• Soup too thin: Remove the lid and simmer uncovered to reduce and concentrate the broth. Alternatively, mash some of the squash into the soup to thicken it naturally.
