  • 1 pound Beef Chuck Roast (cut into 2-inch cubes)
  • 1/2 large White Onion (kept in one piece)
  • 4 cloves Garlic (smashed)
  • 6 cups Beef Broth (low sodium)
  • 2 teaspoons Salt (plus more to taste)

The Vegetables

  • 3 large Carrots (peeled and cut into 2-inch chunks)
  • 1 large Chayote Squash (peeled, pit removed, and sliced into wedges)
  • 2 ears Corn on the Cob (cut into 3 pieces each)
  • 3 medium Red Potatoes (halved or quartered)
  • 2 medium Zucchini (Calabacita) (cut into thick rounds)
  • 1/4 head Green Cabbage (cut into two thick wedges)
  • 1 small bunch Cilantro (tied with kitchen twine)

For Serving

  • 1 pack Warm Corn Tortillas (served on the side)
  • 2 cups Mexican Red Rice (optional, for serving inside the soup)

👨‍🍳 Instructions

  1. 1

    Place the beef shank, beef chuck roast, smashed garlic, onion piece, and salt into the Instant Pot inner pot.

  2. 2

    Pour in the beef broth and enough water to reach the 'Max Fill' line if necessary, ensuring the meat is fully submerged.

  3. 3

    Secure the lid and set the valve to 'Sealing'. Select 'Pressure Cook' or 'Manual' on High Pressure for 45 minutes.

  4. 4

    While the meat cooks, prep your vegetables. Ensure the carrots, potatoes, and corn are cut into large, uniform chunks so they don't overcook later.

  5. 5

    Once the timer beeps, allow for a 15-minute Natural Pressure Release (NPR) to keep the meat tender. Follow with a Quick Release for any remaining steam.

  6. 6

    Carefully open the lid. Use a slotted spoon to remove the onion piece and the garlic cloves and discard them. Skim any excess fat from the surface of the broth if desired.

  7. 7

    Add the corn, potatoes, carrots, and chayote to the pot. These are the 'hard' vegetables that require more time.

  8. 8

    Add the cilantro bundle and the cabbage wedges on top. Do not add the zucchini yet.

  9. 9

    Reseal the lid. Set the Instant Pot to 'Pressure Cook' on High Pressure for 4 minutes. This short time ensures the vegetables are tender but not mushy.

  10. 10

    When the cycle finishes, perform an immediate Quick Release of the pressure.

  11. 11

    Open the lid and stir in the zucchini rounds. The residual heat of the broth will perfectly cook the zucchini in about 3-5 minutes without them falling apart.

  12. 12

    Taste the broth and adjust the seasoning with more salt if needed. Remove the cilantro bundle before serving.

  13. 13

    To serve, place a piece of meat and a variety of vegetables in a large deep bowl, then ladle the hot broth over the top.

💡 Chef's Tips

Always use bone-in beef shank (chambarete) if possible; the marrow provides an incredible silky texture and richness to the broth. Avoid cutting your vegetables too small; large chunks are traditional and prevent them from disintegrating under pressure. If you prefer a very clear broth, you can par-boil the meat for 5 minutes on the stove, rinse it, and then start the Instant Pot process. Don't skip the chayote! It has a mild, sweet flavor and a unique texture that is essential for an authentic Caldo de Res. Leftovers taste even better the next day as the flavors continue to marry in the refrigerator.

🍽️ Serving Suggestions

Serve with a side of warm, charred corn tortillas for dipping into the broth. Add a scoop of Mexican Red Rice directly into the bowl for a heartier meal. Provide plenty of fresh lime wedges; the acidity cuts through the richness of the beef perfectly. Offer a side of minced serrano peppers or a smoky Salsa Macha for those who enjoy a spicy kick. Pair with a refreshing glass of Hibiscus Agua Fresca (Jamaica) to balance the savory heat.
