Sopa De Conchas is a traditional Mexican comfort soup made by toasting small shell-shaped pasta and simmering it in a blended tomato, onion, and garlic broth. The pasta gets a beautiful golden toast before the tomato base is added, giving the dish a slightly nutty, deep flavor.
Seasoned simply with salt, pepper, and a hint of cumin, this soup comes together in just 30 minutes. It's perfect for a light lunch or a warming family dinner, especially when served with fresh cilantro, a squeeze of lime, and warm corn tortillas on the side.
My tia Lupita used to make sopa de conchas on rainy Sunday afternoons when the whole house smelled like toasted pasta and blended tomatoes, and even the dog would hover near the kitchen door waiting for a dropped shell or two.
Once I made this for a friend who was sick with a cold and she texted me three days later asking for the recipe because she could not stop thinking about the broth.
Ingredients
- Small shell pasta (conchas) (1 cup): The star of the show so pick a brand with sturdy shells that will not fall apart during the toasting step.
- Ripe tomatoes (3, chopped): Vine ripened tomatoes give the broth a brighter reddish orange color and a sweeter edge than canned ever could.
- White onion (1/4 small, chopped): Just a quarter is enough to give the base depth without overpowering the gentle tomato flavor.
- Garlic (2 cloves): Two cloves is the sweet spot but you can sneak in a third if your household runs on garlic like mine does.
- Chicken or vegetable broth (4 cups): Use vegetable broth to keep it fully plant based or chicken broth for that classic homey richness.
- Vegetable oil (2 tablespoons): Any neutral oil works here since its mainly for toasting the pasta.
- Salt (1 teaspoon, or to taste): Start with a teaspoon and adjust at the end because the broth already contributes saltiness.
- Ground black pepper (1/4 teaspoon): Freshly cracked pepper makes a quiet but noticeable difference.
- Cumin (1/4 teaspoon, optional): A tiny pinch adds warmth without turning the soup into something it is not.
- Chopped cilantro (2 tablespoons, optional): Scatter it on top right before serving so it stays bright and fragrant.
- Lime (1, cut into wedges, optional): A generous squeeze of lime at the table lifts every single spoonful.
Instructions
- Blend the base:
- Toss the chopped tomatoes, onion, and garlic into a blender and let it run until the mixture is completely smooth with no chunks hiding in there.
- Toast the shells:
- Heat the oil in a medium pot over medium heat then add the dry shell pasta and stir constantly until the shells turn a warm golden brown and smell nutty.
- Cook the tomato mixture:
- Pour the blended tomato through a fine mesh strainer straight into the pot with the toasted pasta and let it cook for a few minutes until it deepens in color and starts smelling incredible.
- Add the broth and seasonings:
- Pour in the broth along with the salt, pepper, and cumin if you are using it then give everything a good stir and bring it to a gentle boil.
- Simmer until tender:
- Drop the heat to a simmer and leave the pot uncovered for about ten to twelve minutes until the shells are soft but still hold their shape.
- Finish and serve:
- Taste the broth one last time and adjust the salt if needed then ladle into bowls and top with cilantro and a wedge of lime.
I once ladled this soup into a thermos for a road trip and it was the only thing that kept me warm when our car heater gave out somewhere outside of Austin.
Making It Your Own
Drop a diced jalapeno into the blender with the tomatoes if you want a gentle kick that builds with every spoonful, or stir in a pinch of chili powder for smoky warmth without extra heat.
Serving Suggestions
This soup loves warm corn tortillas torn into pieces and dropped right into the bowl, and a slice of queso fresco crumbled on top never hurt anybody either.
Storage and Reheating
The pasta will soak up broth as it sits in the fridge so when you reheat it the next day just splash in a little water or extra broth to bring it back to life.
- Store leftovers in an airtight container for up to three days.
- Freezing works but the pasta texture will be softer when thawed.
- Add fresh lime juice only after reheating so it tastes bright instead of flat.
Some dishes feed the body and some feed the soul, and this little bowl of toasted shells in tomato broth quietly does both without any fuss at all.
Recipe FAQs
- → What type of pasta works best for Sopa De Conchas?
-
Small shell pasta (conchas) is traditional and ideal because the shells hold the broth beautifully. You can find them in most grocery stores in the pasta aisle or in the Mexican foods section. Medium shells work as a substitute if small ones aren't available.
- → Why do you toast the pasta before adding the broth?
-
Toasting the shell pasta in oil before adding the liquid gives it a slightly nutty flavor and helps it hold its shape during cooking. This technique, common in Mexican cooking, also adds a golden color and prevents the pasta from becoming mushy in the broth.
- → Can I make Sopa De Conchas vegan?
-
Yes, simply swap the chicken broth for vegetable broth. The rest of the ingredients are already plant-based. Just be sure to check your pasta packaging, as some dried pastas contain egg.
- → How should I store and reheat leftover soup?
-
Store leftovers in an airtight container in the refrigerator for up to 3 days. Keep in mind the pasta will absorb more broth as it sits, so add a splash of broth or water when reheating on the stovetop or in the microwave.
- → What can I serve with Sopa De Conchas?
-
Warm corn tortillas are the most traditional accompaniment. You can also serve it with crusty bread, a side of avocado slices, or a simple green salad. For extra richness, some people like to add a dollop of crema or shredded cheese on top.
- → Can I add spice to this soup?
-
Absolutely. Add a diced jalapeño or a pinch of chili powder when blending the tomato base for a gentle heat. For more control, you can also stir in chipotle in adobo sauce or serve with hot sauce on the side so each person can adjust to their preference.
