Ingredients for baja soup
Simple seafood, bold spices, and crispy tortilla magic—here's what makes this Baja soup shine.
| Ingredient | Amount | Notes |
|---|---|---|
| White Fish Fillets 🐟 | 1 ½ lb | Cod, halibut or mahi-mahi preferred |
| Yellow Onion 🧅 | 1 whole | Medium size, diced small |

| Jalapeño Pepper 🌶️ | 1 whole | Seeds removed, finely chopped |
| Red Bell Pepper 🍆 | 1 whole | Diced small for sweetness |
| Canned Chipotle Peppers in Adobo 🌶️ | 2 tbsp | Adobo sauce included, blended smooth |
| Canned Tomato Sauce 🍅 | 1 cup | San Marzano preferred for sweetness |
| Fish or Seafood Stock 💧 | 4 cups | Homemade or high-quality store-bought |
| Light Beer 🍺 | ½ cup | Mexican lager preferred |
| Lime Juice 🍋 | ¼ cup | Freshly squeezed, strained |
| Corn Tortillas 🌽 | 6 whole | Cut into strips for frying |
| Vegetable Oil 🫒 | 1 cup | For frying tortilla strips |
| Fresh Cilantro 🌿 | ¼ cup | Chopped for garnish |
| Avocado 🥑 | 1 whole | Diced for garnish |

The fish is the star, so grab fresh white fillets—cod or halibut hold up best. Whole Foods or your local fishmonger usually have the best quality. If you can't find fresh, frozen works too (thaw in the fridge overnight). The tortillas? Mission brand from the store is perfect—just make sure they're corn, not flour. For the chipotle, Penzeys has the best adobo sauce if you want to splurge, but the regular canned stuff works fine. The beer adds depth—Modelo or Pacifico are my go-tos, but any pale lager will do.
No fresh fish? Shrimp or scallops work beautifully—just cook them separately and add at the end. Out of beer? Fish stock plus a splash of lime keeps the flavor. The tortilla strips can be pre-made and frozen—Trader Joe's sells them ready to fry, which is a game-changer. For the jalapeño, keep the seeds if you love heat, but remove them for a milder kick. The avocado should be ripe but firm—Hass variety is ideal. If you can't find San Marzano tomatoes, any good-quality canned tomatoes will work, but you might need to adjust seasoning.
This soup tastes even better the next day—4-5 days in the fridge, honestly. The tortilla strips stay crispy for about 2 hours if you fry them fresh, but you can reheat them in a dry pan for extra crunch. Store the broth separately if you're not using it all at once—freezes perfectly for 3 months. I always make a double batch because it disappears fast. Garnish with extra lime and cilantro right before serving—that's when it looks restaurant-worthy.

Step-by-step instructions for Baja fish soup
Let's build this bold, crispy-topped Baja fish soup that packs layers of smoky heat and bright freshness.
Build the Flavor Base
Heat the 1 cup vegetable oil in a large Dutch oven over medium heat. Add the 1 whole yellow onion and 1 whole red bell pepper (diced small) and cook for 5-6 minutes until softened and just beginning to color. You're looking for a sweet, caramelized aroma—this is the foundation of your soup.
Add the 6 cloves garlic cloves (minced) and cook for 30 seconds until fragrant—don't let it brown or it'll turn bitter. Stir in the 1 whole jalapeño pepper (finely chopped, seeds removed) and cook for another 30 seconds to release its heat. Here's where the magic happens: add the 2 tablespoons canned chipotle peppers in adobo (blended smooth) and 1 teaspoon ground cumin, stirring constantly for 1 minute until the chipotle peppers darken slightly and perfume the air with smoky depth.
Develop the Broth
Pour in the 1 cup canned tomato sauce and stir to combine with the vegetables. Let it simmer for 2 minutes until slightly thickened. This step deepens the tomato flavor and removes any raw taste from the canned sauce. Add the 4 cups fish or seafood stock and bring to a gentle boil, then reduce heat to medium-low and let it simmer for 10 minutes to let all the flavors meld together.
Here's the thing—this simmering time allows the chipotle and cumin to fully infuse the broth. You'll notice the soup developing a rich, reddish hue and an aroma that's both smoky and slightly sweet. This is your flavor bomb base, so don't rush this step. If you taste it now, you should get a balance of heat, earthiness, and acidity.
Cook the Fish
While the broth simmers, season the 1.5 lb white fish fillets with 1.5 teaspoons salt and 0.5 teaspoon ground black pepper. Gently add the fish to the simmering broth and cook for 4-5 minutes—just enough time to cook through without falling apart. The fish is done when it flakes easily with a fork and reaches an internal temperature of 145°F.
Remove the fish with a slotted spoon and set aside. Here's a pro tip: don't overcook the fish or it'll turn rubbery. The broth will continue cooking while you prepare the crispy toppings, so timing is key. The fish should be opaque throughout with no translucent edges when it's done.
Fry the Tortilla Strips
Cut the 6 whole corn tortillas into ¼-inch thick strips. Heat ½ cup vegetable oil in a skillet over medium-high heat until shimmering. Fry the tortilla strips in batches for 1-2 minutes until golden brown and crispy—you want that perfect crunch that'll contrast beautifully with the creamy soup.
Drain the fried tortilla strips on paper towels to remove excess oil. The strips should be crisp enough to stand up to the hot soup without turning soggy. If they're not golden enough, fry them another 30 seconds—this is where you get that authentic Baja crunch. Keep them warm while you finish the soup.
Finish and Serve
Return the broth to a simmer and stir in the 0.5 cup light beer and 0.25 cup lime juice. Simmer for 2 minutes to let the beer mellow out and the lime brighten the flavors. Gently stir in the 0.25 cup fresh cilantro (chopped) and break the cooked fish into chunks, returning it to the broth.
Ladle the soup into bowls and top immediately with the crispy tortilla strips, diced 1 whole avocado, and a final sprinkle of cilantro. The contrast of creamy soup, smoky broth, crispy tortillas, and cool avocado is what makes this dish sing. Serve with lime wedges on the side so everyone can adjust the brightness to their taste.
Pro Tips For Making Baja Soup
- Sear the Fish First: I learned this the hard way—adding raw fish fillets to simmering broth turns them rubbery. Instead, pat them dry, season lightly with salt, and sear them skin-side down in a hot pan for 2-3 minutes until golden. Then transfer to a plate and finish cooking in the soup for just 3-4 minutes—this keeps them tender and flavorful.
- Char the Peppers: Does it look weird? Yes. Does it work? Every single time. Roast the red bell pepper and jalapeño directly over a gas flame (or under a broiler) until blackened in spots—this adds a smoky depth that raw peppers can’t match. Peel off the skin, dice, and toss them in while the soup simmers for that authentic Baja punch.
- Sweat, Don’t Burn: Onions and garlic are the soup’s foundation, but I used to rush them and end up with bitter, browned bits. Instead, cook them low and slow in a little oil (about 2 tablespoons) for 8-10 minutes until soft and translucent. Add a splash of water if they start sticking—this builds flavor without charring.
- Save the Broth: Skip the urge to pour out the fish’s poaching liquid—it’s packed with flavor. After searing the fish, deglaze the pan with ¼ cup of water or white wine, scraping up every browned bit. Add this to the soup later; it’ll deepen the broth’s richness without extra effort.
Best sauces and condiments for this recipe
Smoky Chipotle Cream
This velvety sauce transforms your soup into a creamy, smoky masterpiece. Blend ½ cup sour cream, 2 tbsp adobo sauce from the canned chipotle peppers, 1 tbsp lime juice, and ½ tsp salt until smooth. Stir 2 tbsp of this mixture into each bowl of soup right before serving—it adds richness while keeping the dish light. 🌶️
Avocado-Lime Crema
For a fresher, tangier option, mash ½ ripe avocado with 2 tbsp sour cream, 1 tbsp lime juice, ½ tsp cumin, and salt to taste. This sauce highlights the soup’s bright flavors while adding a creamy texture. Drizzle generously over the top or serve on the side for dipping tortilla strips. 🥑
Spicy Tomatillo Salsa
Roast 4 tomatillos (husks removed) in a skillet over medium heat for 5 minutes until charred. Blend with 1 jalapeño, 2 tbsp cilantro, 1 tbsp lime juice, and ½ tsp salt until chunky. This salsa adds a tangy, spicy contrast that cuts through the richness of the soup. Serve as a garnish or on the side. 🌶️
Crispy Tortilla Oil
Save the leftover oil from frying the tortilla strips—it’s packed with flavor! Heat it in a small saucepan until shimmering, then drizzle over the soup just before serving. The oil carries the smoky, crispy essence of the tortillas, enhancing every spoonful. For extra drama, sprinkle with crushed red pepper flakes before drizzling. 🔥
Lime-Cilantro Butter
Mix 2 tbsp softened butter, 1 tbsp chopped cilantro, 1 tsp lime zest, and ½ tsp salt into a paste. Dollop small amounts onto each bowl of soup and let it melt slightly from the heat. This adds a luxurious, herby finish that ties all the flavors together. Perfect for those who love a buttery touch. ✨

Frequently asked questions about Baja fish soup
Can I make Baja fish soup with shrimp instead of white fish?
Shrimp works beautifully and adds a different texture. Use 1.5 pounds of peeled and deveined shrimp and cook them for just 2-3 minutes in the simmering broth—don't overcook or they'll turn rubbery. Add them right before serving to keep them tender. For extra flavor, toss them with a pinch of smoked paprika and garlic powder before adding to the soup.
How can I make the tortilla strips extra crispy?
For maximum crunch, fry the tortilla strips in small batches at medium-high heat until they're golden brown and puffed slightly. Drain them on a wire rack (not paper towels) to prevent steaming. Keep them warm in a 200°F oven while finishing the soup. For even more crunch, sprinkle them with a tiny bit of cornstarch before frying.
What's the best way to store leftovers?
Store the soup (without tortilla strips) in an airtight container in the fridge for up to 4-5 days. The flavors actually improve overnight! Reheat gently on the stove, then add fresh tortilla strips and avocado when serving. For the tortilla strips, store them separately in a sealed container—they'll stay crispy for about 2 hours at room temperature.
Can I make this soup vegetarian?
Yes! Swap the fish for chickpeas or white beans (1 can, drained) and add 1 zucchini and 1 cup corn kernels for texture. For protein, use tofu or tempeh (press and cube before cooking). Boost the umami with an extra 1 tbsp soy sauce or 1 tsp miso paste in the broth. The smoky chipotle and lime flavors still shine in a plant-based version!
Why does my soup taste too salty?
Fish stock and canned tomatoes often contain hidden salt. Taste the broth before adding fish—it should be seasoned but not salty. If needed, dilute with ½ cup water or add 1 tbsp lime juice to balance the flavor. For future batches, use low-sodium stock and reduce canned tomato salt by half. Remember, you can always add more lime or avocado to brighten the flavors.
