History of Tortilla Soup: Where This Mexican Classic Began

Slow cooker chicken tortilla soup is a Mexican-style soup built on a brothy, tomato-red base with tender shredded chicken, beans and a gentle heat from chiles. The flavor is smoky and savory, with the sweetness of fire-roasted tomatoes, and the soup is made to be buried under toppings.

The best part is the tortilla. Crisp strips or croutons go on at the last second, soaking up broth at the edges while staying crunchy in the middle. People love this soup because it eats like a full meal, keeps well, and lets everyone dress their own bowl.

Where tortilla soup comes from

Tortilla soup, or sopa de tortilla, is described as a traditional Mexican soup, and its exact origin is unknown. It is particularly common around Mexico City, and traditional versions pair chicken broth with roasted tomatoes, onion, garlic and chiles, plus tortillas cut into strips and fried.

You will also see it called sopa azteca or Aztec soup. One food-etymology source gives Mexico City as the probable birthplace, noting the city's many Aztec architectural remains. That is a guess about geography, not a documented origin. The earliest print citation it lists for sopa azteca is a 1958 cookbook, Especialidades de la Cocina Criolla, so the name may be younger than the soup itself.

A different account, from a Mexico travel article, places the soup in the state of Tlaxcala, whose name it glosses as "place where tortillas abound." It calls the dish pre-Hispanic in origin, then describes it as a hybrid of the Mexican tortilla and the soup-making traditions the Spanish brought in the 16th century.

What the sources agree on is the mix of old and new. Tomato, chiles and corn were already in use among the Aztecs and Maya before the Spanish arrived. Chicken broth, onion and garlic are usually credited to the Spanish. Few dishes show that meeting of cuisines as plainly as a bowl of tortilla soup.

How it varies

The traditional version starts with a broth seasoned with roasted tomato, chiles, garlic and onion, then adds fried tortilla strips. Many cooks blend the base smooth and use dried chiles for a deeper, earthier flavor. Toppings usually include avocado, cheese, a drizzle of cream and a squeeze of lime.

The slow cooker version is a modern, practical take. Chicken breasts cook gently in the pot with fire-roasted tomatoes and beans, and the meat shreds easily at the end. Beans are not a classic part of the soup, but they make it heartier. The tortilla croutons are a smart shortcut that gets you the same crunch with less fuss than frying strips in a pot of oil. It is not the soup you would be served in Mexico City, but it keeps the spirit of it.

When to make it

This soup fits Quick Favorites best: a weeknight when you want dinner waiting for you at the end of the day. Fill the pot in the morning, and all that is left in the evening is shredding the chicken and making the crunchy topping.

It is also made for Cozy Comfort. October is a good time to start, when the first cold evenings arrive and the last tomatoes, poblanos and corn of the season are still at the market. It works just as well in January, when winter citrus is at its best and a lime or orange wedge brightens a heavy week.

For a Weekend Project, make a Sunday of it. Cut and bake your own tortilla strips, set out a toppings bar with avocado, cheese, cilantro, radishes and lime, and let everyone build a bowl while the pot keeps warm. It is an easy way to feed a crowd on a game day.

What to serve with it

Quesadillas. Melted cheese in a crisp tortilla is a natural partner for dunking, and it makes the meal more filling.
A crisp green salad with citrus. Something sharp and cool, such as greens with lime dressing, balances the warm, rich soup.
Mexican rice. Serve it on the side or spoon some into the bowl to stretch the soup for a bigger table.
A cold lager or a margarita. Light beer or a lime-forward cocktail cuts through the smoky broth.
Agua de jamaica. A tart hibiscus cooler works well for a table with kids or anyone skipping alcohol.

Make it at home

The version we cook on Meez comes from Delish. It uses a slow cooker, fire-roasted tomatoes and beans, and the tortilla croutons you should not skip. Get the recipe for the full ingredients and method, or cook it step by step in Cook Mode if you want your hands free at the stove.

Questions about tortilla soup

Is tortilla soup the same as sopa azteca?

Yes, they are two names for the same soup. Aztec soup, Aztec tortilla soup and sopa azteca all refer to tortilla soup, and the "Aztec" name seems to have come into print in the mid-20th century.

Where does tortilla soup come from?

Nobody knows exactly. Mexico City is often named as the probable origin, while some accounts place it in Tlaxcala, and most describe it as a blend of native Mexican ingredients and Spanish soup traditions.

What do you serve with chicken tortilla soup?

Quesadillas, a citrusy green salad or Mexican rice all work well. A cold lager, margarita or hibiscus agua fresca rounds out the table.

How is tortilla soup different from pozole?

Tortilla soup is a chile-and-tomato broth thickened with the crunch of fried or baked tortillas on top. Pozole is a different Mexican soup built around hominy, which gives it a chewier, heartier texture.
