What is Mexican Oxtail Soup?
Mexican oxtail beef soup is a rustic, slow-simmered soup that incorporates oxtails—meaty sections of cow tail renowned for their gelatin-rich connective tissue. Cooked with aromatics, hearty cuts of beef, and a bounty of fresh vegetables, this broth-based dish is both deeply nourishing and intensely flavorful. Known in Spanish as caldo de colita de res, it’s a staple in traditional Mexican kitchens and beloved for its comfort and depth of taste. The key to its unforgettable flavor lies in a rich, homemade broth extracted from bones and marrow during a long, gentle simmer.

Step-By-Step Instructions: How to Make Mexican-Style Oxtail Soup
Prepare the Broth:
In a large stock pot, bring water, salt, and several garlic cloves to a robust boil. Add oxtails, beef shanks, soup bones, and a halved onion. Continue to boil, then reduce to a simmer. Skim off any foam as it appears.
Tip: For an ultra-clear broth, skim often during the first stage of cooking.Slow Simmer:
With the lid partially covering the pot, let the meat simmer gently for around 2 to 2.5 hours. This allows the collagen and bones to yield their rich flavors and the meat to become tender.Add Vegetables:
Once the meat is nearly falling off the bone, add potatoes, carrots, corn rounds, chayote, and zucchini. Increase to a lively boil for a minute, then return to a low simmer and cook covered for 30 minutes.Final Seasoning:
Uncover the pot and stir in chopped cilantro, coriander, asafran (if using), and additional salt or pepper. Cook uncovered for a final 10 minutes to allow the flavors to meld.Serve:
Present piping hot with lime wedges, salsa casera, and homemade tortillas. Don’t forget to scoop out and enjoy the bone marrow (tuétano) on tortillas with a dash of sea salt—a beloved Mexican delicacy often enjoyed alongside the soup.
Traditional Equipment Recommendations
- Large stock pot or Dutch oven
- Sharp chef’s knife and sturdy cutting board
- Soup ladle for serving
- Skimmer or slotted spoon for removing foam
Optional Variations & Expert Tips
Recipe Variations
- Slow Cooker Method: Prepare the beef and bones as in the main recipe, place half batch in a 6-quart slow cooker, cover with water, and cook on low for 8 hours. Add vegetables, cook on high for 30 minutes, then finish as above.
- Oxtail Noodle Soup: Omit potatoes and add cooked short pasta like ditalini or elbow macaroni just before serving to prevent sogginess from extended sitting in broth.
- Spicy Caldo: Include sliced jalapeño, guajillo, or ancho chiles in the broth for extra warmth and color.
- Vegetarian Adaptation: Use mushrooms and hearty root vegetables, omitting meat, for an earthy but lighter soup.
Expert Tips
- Skim the Broth Often: This removes impurities and keeps the finished soup clear and appetizing.
- Don’t Rush the Simmer: The rich flavor develops during patient simmering. Allow at least two hours for the beef to soften and broth to deepen.
- Add Greens Last: For optimal color and flavor, add cilantro and other herbs in the final minutes.
- Marrow Bonus: Serve the bone marrow on toasted tortillas with a sprinkle of sea salt—a classic accompaniment known as taco de tuétano.
Serving Suggestions
- Present each bowl with a generous chunk of each vegetable, a section of oxtail, and plenty of broth.
- Set out lime wedges for guests to squeeze into their bowls.
- Offer salsa casera or your favorite homemade salsa for an optional spice kick.
- Warm corn tortillas are essential for scooping up hearty bites or for slathering with bone marrow.
- For a complete meal, pair with Mexican rice or a side salad for balance.
