📝 About This Recipe

Caldo de Res is a quintessential Mexican comfort food, a rustic and vibrant beef soup that simmers bone-in shank with a colorful garden of vegetables. This dish is celebrated for its clear, deeply savory broth and the tender, melt-in-your-mouth texture of the beef and marrow. It is a complete meal in a bowl, offering a nostalgic taste of home that balances hearty protein with the freshness of corn, chayote, and lime.

🥗 Ingredients

The Beef & Broth Base

  • 3 pounds Beef Shank (Chambarete) (cut into 2-inch thick pieces, bone-in for marrow)
  • 12-14 cups Water (enough to cover meat by 3 inches)
  • 1 large White Onion (halved)
  • 1 head Garlic (top sliced off to expose cloves)
  • 2 tablespoons Sea Salt (adjust to taste)

The Hearty Vegetables

  • 3 large Carrots (peeled and cut into thick rounds)
  • 2 ears Corn on the Cob (Elote) (husked and cut into 3-inch rounds)
  • 2 pieces Chayote Squash (pitted and cut into large wedges)
  • 3 medium Red Potatoes (scrubbed and halved)
  • 3 medium Zucchini (Calabacita) (cut into thick half-moons)
  • 1/2 head Green Cabbage (cut into large wedges)
  • 1 large bunch Fresh Cilantro (tied with kitchen twine)

For Serving & Garnish

  • 3 pieces Limes (cut into wedges)
  • 2 cups Spanish Rice (cooked, kept warm)
  • 3 pieces Salsa Macha or Serrano Peppers (finely chopped for heat)
  • 12 pieces Corn Tortillas (warmed)

👨‍🍳 Instructions

  1. 1

    In a very large stockpot (at least 10-12 quarts), place the beef shank pieces and cover with 12-14 cups of cold water.

  2. 2

    Bring the water to a rolling boil over high heat. As it boils, a grey foam (impurities) will rise to the surface; use a fine-mesh skimmer or spoon to remove all of this foam to ensure a clear broth.

  3. 3

    Once the broth is clear, add the halved onion, the head of garlic, and the sea salt. Reduce heat to low, cover partially, and simmer gently for about 1.5 to 2 hours until the beef is tender but not yet falling off the bone.

  4. 4

    Remove the onion and the head of garlic from the pot and discard them; they have fulfilled their aromatic destiny.

  5. 5

    Add the corn rounds and the carrots to the pot. These take the longest to cook and provide sweetness to the base. Simmer for 10 minutes.

  6. 6

    Add the potatoes and the chayote wedges. Continue to simmer for another 10-12 minutes. You want the vegetables to be fork-tender but still holding their shape.

  7. 7

    Gently stir in the cabbage wedges and the zucchini. These cook quickly and you want to avoid them becoming mushy.

  8. 8

    Submerge the tied bunch of cilantro into the broth. Let everything simmer together for a final 10 minutes.

  9. 9

    Taste the broth. This is the crucial 'Chef's moment'—add more salt if needed to make the beef flavors pop.

  10. 10

    Turn off the heat. Remove the cilantro bunch before serving to keep the presentation clean.

  11. 11

    To serve, place a piece of beef and a variety of vegetables into a large, deep bowl. Ladle a generous amount of hot broth over the top.

💡 Chef's Tips

Don't rush the simmering; a low, slow bubble ensures the beef remains succulent rather than tough. Always skim the foam at the beginning; it is the secret to a professional, clear broth rather than a cloudy one. If you can't find chayote, you can substitute with extra zucchini or even green beans, though chayote adds a unique texture. To save time, you can cook the beef in a pressure cooker for 45 minutes, then transfer to a pot to finish with the vegetables. Save the marrow! Use a small spoon to scoop the buttery marrow from the bones onto a warm tortilla with a pinch of salt.

🍽️ Serving Suggestions

Serve with a side of warm Mexican red rice which can be added directly into the soup bowl for extra heartiness. Provide plenty of fresh lime wedges; the acidity cuts through the richness of the beef marrow perfectly. Pair with warm, charred corn tortillas for dipping into the broth. Offer a spicy salsa roja or chopped fresh serrano peppers on the side for those who enjoy a kick of heat. A cold Mexican lager or a glass of Jamaica (hibiscus tea) balances the warmth of the soup beautifully.
