What is Caldo de Pescado?

Caldo de Pescado literally means “fish broth” in Spanish, and it’s a traditional Mexican soup that celebrates fresh seafood and humble ingredients. While every region in Mexico has its own variation, the base usually features white fish, a tomato-and-chile broth, and an assortment of seasonal vegetables.

Think of it as Mexico’s answer to chicken noodle soup—but with way more personality. The guajillo and chipotle peppers bring warmth and a mild kick, while oregano and shrimp bouillon deepen the savory notes. It’s typically served with lime wedges, tortillas, and maybe even a side of rice. The best part? It’s easy to customize. Whether you prefer cod, tilapia, halibut, or red snapper, the broth welcomes them all. This is a dish that’s equally at home in a seaside cantina or your kitchen after a long day.

Ingredients Needed to Make Caldo de Pescado

Here’s what you’ll need to make a pot of this delicious Mexican Fish Soup:

• 2 lb white fish chunks (cod, halibut, or tilapia work great)
• 1 lb tomatoes
• 2 guajillo chilies, stem and seeds removed
• 1 chipotle pepper in adobo sauce
• 1 small onion, halved
• ½ tsp black peppercorns
• 2 small potatoes, cut into ½-inch cubes
• 1 large carrot, thickly sliced
• 1 leek, cut into rings
• 2 medium zucchini, cut into ½-inch cubes
• 3 Tbsp olive oil
• 2 garlic cloves, peeled
• 1 Tbsp oregano
• 1 Tbsp shrimp bouillon
• Salt, to taste

Each ingredient plays a role here: the tomatoes and chiles create a rich base, the fish adds protein and depth, and the vegetables provide texture and balance. It’s a complete meal in one bowl—comfort, color, and nutrition all simmering together.

Instructions to Make Caldo de Pescado – Step by Step

Step 1: Prepare the Flavor Base

To start, boil the tomatoes in a pot of water until they’re soft—about 10 minutes. This step draws out their natural sweetness and helps them blend smoothly later. Once done, turn off the heat and toss in your guajillo chiles. Push them into the hot water so they soften for about 15 minutes. This simple move unlocks their deep red color and smoky undertones.

Step 2: Blend the Magic

Now grab your blender or food processor. Add the softened tomatoes and guajillo chiles, along with the chipotle pepper, onion, garlic, black peppercorns, and one cup of water. Blend until smooth—this is your flavor bomb, the heart of Caldo de Pescado. Strain the sauce through a fine sieve into a bowl to remove any tough bits from the chiles. Set it aside like the star it is, waiting for its big moment.

Step 3: Sauté the Vegetables

Heat olive oil in a large stockpot over medium heat. Toss in your carrots, zucchini, potatoes, and leek. Let them sauté for about 3 minutes. This short cook time gives them a golden edge while releasing their natural sweetness. You’re not cooking them fully yet—just giving them a flavorful head start.

Step 4: Add the Sauce and Seasonings

Pour the blended sauce into the pot. The moment it hits the oil and veggies, you’ll smell that incredible aroma that says “this is going to be good.” Stir in the shrimp bouillon, oregano, and salt. Let everything simmer for about 5 minutes so the flavors marry and deepen.

Step 5: Add the Broth and Simmer

Pour 6 cups of water into the pot and stir. If you’re using fish heads or tails for extra flavor, now’s the time to add them—they’ll enrich the broth beautifully. If not, just continue cooking the vegetables for another 10 minutes. You’re looking for them to be tender but not mushy.

Step 6: Add the Fish

Now the star of the show—add the white fish chunks. Bring the pot to a gentle boil, then lower the heat to medium-low and let it simmer for about 5 to 7 minutes. The fish cooks quickly and becomes tender, flaking easily with a spoon. Don’t overcook it—you want juicy, delicate pieces swimming in that bold broth.

Step 7: Adjust and Serve

Taste your broth and adjust the salt if needed. Once everything tastes just right, turn off the heat and let the soup rest for a couple of minutes. This allows the flavors to settle beautifully. Ladle the Caldo de Pescado into bowls, making sure everyone gets a generous portion of fish and vegetables. Serve with lime wedges, warm corn tortillas, and a sprinkle of fresh cilantro if you like.

What to Serve with Caldo de Pescado

Traditionally, Caldo de Pescado is served with warm tortillas, a side of rice, and plenty of lime wedges for squeezing over the top. You can also serve it with avocado slices or even crusty bread if you’re feeling fusion-y. If you want to go the extra mile, try pairing it with a light side like Asian-Style Ground Beef Lettuce Wraps for a contrast of textures.

Key Tips for Making Caldo de Pescado

1. Choose the right fish: Stick to firm white fish that won’t fall apart—cod, halibut, or red snapper work best.
2. Don’t skip straining the sauce: It makes the broth smooth and restaurant-quality.
3. Balance your spice: If you prefer less heat, skip the chipotle. For more kick, add an extra one.
4. Add seafood variety: Shrimp, clams, or mussels can be added for a more seafood-rich version.
5. Fresh herbs matter: Finish the soup with cilantro or parsley to bring brightness to the earthy broth.

Storage and Reheating Tips for Caldo de Pescado

If you somehow end up with leftovers (lucky you), store your Caldo de Pescado in an airtight container in the refrigerator for up to 3 days. The flavors deepen overnight, making it even better the next day. To reheat, warm it on the stovetop over medium heat until hot—avoid boiling it again, as that can overcook the fish. You can also freeze the broth separately (without the fish) for up to two months. Just add freshly cooked fish when you reheat it.
