Here’s a comforting, nostalgic recipe for Sopa de Conchas—that beloved Mexican shell pasta soup that tastes like childhood in a bowl. Simple ingredients, big flavour.
Authentic Mexican Sopita (Sopa de Conchas)
Serves: 4-6 | Cook Time: 20 minutes
Ingredients
-
2 tbsp vegetable or olive oil
-
1½ cups (7 oz) shell pasta (conchas/sopitas)
-
¼ small white onion, finely diced
-
2 garlic cloves, minced
-
1 can (8 oz) tomato sauce (plain tomato purée)
-
4 cups chicken broth (or water + bouillon—see note)
-
½ tsp ground cumin (optional)
-
½ tsp dried oregano (Mexican if you have it)
-
Salt, to taste
-
Fresh cilantro, chopped (for garnish)
-
Lime wedges (for serving)
Optional Add-Ins:
-
A sprig of fresh epazote (adds authentic earthy flavour)
-
¼ tsp garlic powder
-
Pinch of chili powder for warmth
-
Diced carrots or peas tossed in during the last 5 minutes
Instructions
1. Toast the Pasta (The Most Important Step)
-
Heat the oil in a medium pot or Dutch oven over medium heat. Add the dry shell pasta. Stir constantly for 3-5 minutes until the pasta turns a deep golden-brown—not just lightly toasted. You want it the colour of toasted nuts. This is what gives sopita its signature nutty, rich flavour. Don’t walk away; it goes from golden to burnt quickly.
2. Sauté the Aromatics
-
Quickly add the diced onion and cook, stirring, for about 1 minute. Add the garlic and cook 30 seconds more until fragrant. If the pan looks dry, add a tiny splash more oil.
3. Add the Tomato Broth
-
Pour in the tomato sauce and let it sizzle for 30 seconds, stirring to coat the pasta. This cooks off the raw tomato taste and deepens the colour.
-
Carefully add the chicken broth, cumin, oregano, and a pinch of salt. Stir well.
4. Simmer
-
Bring to a boil, then reduce heat to low. Cover and simmer for 10-12 minutes, or until the shells are tender but not mushy. Stir once or twice during cooking to prevent sticking. The pasta should absorb some broth, leaving you with a slightly thickened, soupy consistency—not dry like rice, but not watery like canned soup.
5. Finish & Serve
-
Taste and adjust salt. Ladle into bowls, garnish generously with chopped cilantro, and serve with lime wedges to squeeze on top. The lime brightens everything.
Important Notes for Authentic Flavour
Broth/Bouillon: In many Mexican kitchens, sopita is made with water and Knorr Caldo de Pollo (chicken bouillon powder) rather than boxed broth. Use about 2 teaspoons bouillon per 4 cups water. If using boxed broth, go for low-sodium—you can always add more salt.
Texture Check: Sopita should be soupy but not brothy. Think of it like a very loose risotto or a pasta in a light, tomato-infused broth. If it absorbs too much liquid, stir in a splash of warm broth or water at the end.
Serving Style: This is often served as a starter (sopa aguada) before the main dish. Kids love it topped with a little crema or a sprinkle of queso fresco. Serve with warm corn tortillas on the side.
Want me to add ground beef or shredded chicken to make it a full main-course caldo, or keep it classic and simple as is?
