1 medium white onion, quartered
5 garlic cloves, peeled
2 bay leaves
1 tablespoon salt
1 teaspoon black pepper
1 teaspoon whole cumin seeds (optional)

Vegetables

3 medium carrots, peeled and cut into large pieces
3 medium Yukon Gold potatoes, quartered
2 ears corn, cut into thirds
2 zucchini, cut into thick slices
2 chayotes, peeled and cubed
¼ small green cabbage, cut into wedges
2 celery stalks, chopped
2 Roma tomatoes, diced

Seasonings

1 teaspoon dried oregano
½ teaspoon smoked paprika (optional)
Salt and black pepper, to taste

Diced white onion
Lime wedges
Warm corn tortillas
Sliced jalapeños
Mexican rice (optional)
Salsa or hot sauce

Step-by-Step Instructions

Step 1: Prepare the Beef

Rinse the beef shanks under cold water and pat them dry. Place the beef into a large stockpot or Dutch oven. Add the water, onion, garlic, bay leaves, salt, black pepper, and cumin seeds.

Step 2: Simmer the Broth

Bring everything to a gentle boil over medium-high heat. Skim off any foam that rises to the surface during the first 15 minutes to keep the broth clear. Reduce the heat to low, cover partially, and simmer for 2 to 2½ hours, or until the beef is fork-tender and easily pulls away from the bone.

Step 3: Add the Hardy Vegetables

Remove the onion and bay leaves if desired. Add the carrots, potatoes, celery, tomatoes, and corn to the pot. Continue simmering for about 20 minutes.

Step 4: Add the Remaining Vegetables

Stir in the chayote and zucchini, cooking for another 10 minutes. Finally, add the cabbage wedges and cook for an additional 8–10 minutes, just until tender but still vibrant.

Step 5: Adjust the Seasoning

Sprinkle in the oregano and smoked paprika, if using. Taste the broth and adjust with additional salt and black pepper as needed.

Step 6: Prepare for Serving

Remove the beef from the bones if preferred and return the meat to the soup. Discard the bones before serving.

Step 7: Garnish

Ladle the hot soup into large bowls, ensuring each serving contains beef, broth, and a generous variety of vegetables. Garnish with chopped cilantro and diced onion.

Step 8: Serve

Serve immediately with fresh lime wedges, warm corn tortillas, Mexican rice, sliced jalapeños, and your favorite salsa for an authentic experience.

Tips & Notes

Beef shanks create the richest and most flavorful broth because of the marrow-rich bones.
Simmer gently instead of boiling rapidly to keep the broth clear.
Cut vegetables into large pieces so they hold their shape during cooking.
Fresh lime juice added just before eating brightens the entire soup.
This soup tastes even better the next day after the flavors have had time to develop.
Refrigerate leftovers for up to 4 days or freeze for up to 3 months.
If the broth reduces too much while simmering, simply add a little more hot water.

Frequently Asked Questions

Can I use another cut of beef?
Yes. Beef chuck roast, short ribs, oxtail, or beef stew meat all work well, although beef shanks provide the most traditional flavor.

Can I make this in a slow cooker?
Absolutely. Cook the beef on LOW for 8–9 hours or HIGH for 5–6 hours. Add the vegetables during the final 2 hours so they don’t become overly soft.

Can I freeze Caldo de Res?
Yes. Cool completely before freezing in airtight containers for up to 3 months.

What can I serve with Caldo de Res?
Warm corn tortillas, Mexican rice, avocado slices, fresh salsa, and lime wedges are traditional accompaniments.

How do I keep the vegetables from becoming mushy?
Add them in stages based on their cooking times, starting with the firmest vegetables and finishing with zucchini and cabbage.
