If there is a dish that embodies the warmth and soul of a traditional Mexican grandmother’s kitchen, it is Caldo de Res. This “Old Fashioned” beef soup is a magnificent, multi-sensory experience. It is a clear, amber broth teeming with massive chunks of tender bone-in beef and a vibrant garden of rustic-cut vegetables.
Unlike modern stews that are thick and heavy, a true Caldo is light and restorative, yet incredibly filling. The hallmark of an authentic version is the inclusion of marrow bones and corn on the cob, which infuse the broth with a silky richness and a subtle sweetness. When you sit down to a bowl of Caldo de Res, you aren’t just eating soup; you are participating in a timeless ritual. It’s the ultimate “cure-all” meal—perfect for a chilly afternoon, a slow Sunday, or whenever you need a dose of culinary nostalgia.
Ingredients
The Meat and Broth
- 2 lbs (900g) Beef Shank (Chamorro): Bone-in is essential for the marrow and flavor.

- 10-12 cups Water: Enough to fully submerge the ingredients.
- 1 Large White Onion: Halved.
- 1 Head of Garlic: Sliced across the top to expose the cloves.
- 2-3 Sprigs of Fresh Mint (Yerba Buena): The “secret ingredient” for authentic aroma.
- 1 tbsp Kosher Salt: Adjust to taste later.
The Vegetables
- 3 Large Carrots: Peeled and cut into thick rounds.
- 2 Ears of Corn (Elote): Husked and cut into 3-inch chunks.
- 2 Large Chayotes: Peeled, pitted, and sliced into wedges.
- 3 Medium Yukon Gold Potatoes: Cut into quarters.
- 1/2 Small Head of Cabbage: Cut into thick wedges.
- 2-3 Small Zucchini (Calabacitas): Cut into thick rounds.

Step-by-Step Instructions
1. Simmer the Beef
Place the beef shank and ribs into your large stockpot. Cover with the 10–12 cups of water. Bring the water to a boil over high heat. As it reaches a boil, you will see a greyish foam rise to the top. Use your skimmer to carefully remove and discard this foam; this ensures your broth stays clear and clean.
2. Flavor the Base
Once the broth is clear, add the halved onion, the head of garlic, the salt, and the sprigs of mint. Reduce the heat to low, cover the pot, and let it simmer gently for about 1.5 to 2 hours. You want the beef to be very tender but not falling completely apart yet.
3. Add the “Hard” Vegetables
Remove the onion and the head of garlic from the broth and discard them. Now, add the vegetables that take the longest to cook: the corn chunks and the carrots. Simmer for about 15 minutes.
4. Layer the Remaining Veggies
Add the potatoes and the chayote wedges to the pot. Continue simmering for another 15 minutes. This staggered approach prevents the softer vegetables from turning into mush while the harder ones soften.
5. The Final Addition
Finally, add the zucchini rounds and the cabbage wedges. These only need about 10–12 minutes to reach a perfect tender-crisp consistency. At this point, the beef should be “fork-tender” and the marrow in the bones should be soft.
6. Season and Adjust
Taste the broth. This is your moment to adjust the salt. Because of the potatoes and corn, the soup can absorb quite a bit of seasoning, so don’t be afraid to add another pinch if it tastes flat.
7. The Assembly
To serve, place a large scoop of cooked Spanish rice in the bottom of a deep bowl. Use tongs to carefully add a piece of beef, a chunk of corn, and a mix of the vegetables. Ladle the hot, fragrant broth over everything.
Tips and Tricks
- The “Mint” Secret: While it might sound unusual, Yerba Buena (spearmint) is the traditional herb used in Mexican Caldo. It doesn’t make the soup taste like candy; instead, it provides a cooling, aromatic lift that cuts through the richness of the beef.
- Keep it Clear: Never stir the soup vigorously once the vegetables are in. This can break the veggies and make the broth cloudy.
- Bone-In is Best: The marrow bones are the heart of this dish. The fat and collagen they release create a “mouthfeel” that you simply cannot get from boneless stew meat.
- Squeeze of Lime: Never skip the lime at the table! The acidity reacts with the beef fat and completely transforms the flavor profile of the broth.
Variations
- Instant Pot Version: You can cook the beef and broth for 45 minutes on high pressure, release, then add the vegetables and cook for another 4–5 minutes on manual.
- Spicy Caldo: If you want a bit of heat infused into the broth, add two whole jalapeños or a dried ancho chili to the pot while the beef is simmering.
- Extra Greens: Some regions add green beans (ejotes) or even a few garbanzo beans for extra texture.
Serving Suggestions
Caldo de Res is a complete meal in a bowl, but it is traditionally served with a side of warm corn tortillas for dipping. Many people like to take the beef out of the soup and roll it into a tortilla with a little salsa and lime to eat alongside the broth. A cold Hibiscus Tea (Agua de Jamaica) is the perfect beverage to balance the heat of the soup.
Storage Instructions
- Refrigerator: Store in an airtight container for up to 3 days. The broth will likely gelatinize when cold—this is a sign of a perfect, collagen-rich Caldo! It will liquify again once heated.
- Reheating: Reheat on the stove over medium heat. If the vegetables have soaked up too much broth, add a half-cup of water or beef stock.
- Freezing: You can freeze the broth and meat, but I recommend removing the zucchini and potatoes before freezing, as their texture becomes grainy upon thawing.
