The garnishes are what make this soup so special. Do not be timid with the offerings: An assortment of shredded cheese, diced avocado, fresh cilantro, salsa and lime wedges will turn a comforting soup into a feast.
You can make the soup ahead — stopping after adding the chicken — and keep it refrigerated for up to four days. Reheat, adding the lime juice when you are ready to serve (and, of course, don’t fry the tortillas or prep the toppings until just before serving!).
Mexican Tortilla Chicken Soup
Start to finish: 45 minutes. Servings: 4 to 6
• For the soup:
2 tablespoons extra-virgin olive oil
2 medium-size onions, chopped
2 cloves garlic, minced
1 1/2 teaspoons ground cumin
1 teaspoon ground coriander
1 teaspoon pure ancho chili powder
1 can (14.5 ounces) crushed tomatoes
6 cups chicken broth, preferably low-sodium
Kosher or coarse salt and freshly ground black pepper, to taste
3 skinless, boneless chicken breasts (about 1 1/2 pounds)
Canola or vegetable oil, for pan-frying
6 corn tortillas, halved and cut crosswise into thin strips
Juice of 1 lime
• To serve (optional, pick and choose):
1 or 2 avocados, peeled and diced
1 cup shredded Monterey Jack cheese
1/2 cup coarsely chopped fresh cilantro leaves
Salsa or Pico de Gallo
1 lime, cut into wedges
Heat the olive oil in a large stockpot over medium heat. Add the onions and garlic and saute until tender and golden, 5 minutes. Stir in the cumin, coriander, and chili powder and cook until fragrant, 1 minute. Add the tomatoes and chicken broth, season with salt and pepper, and bring to a simmer over high heat. Add the chicken breasts and lower the heat to medium-low. Simmer uncovered (don’t let the soup come to a boil), stirring occasionally, until the chicken is just barely cooked through, about 12 minutes. Remove the chicken to a plate and let sit until cool enough to handle. Keep the soup gently simmering over medium-low heat.
Meanwhile, pour the oil to a depth of 1 inch into a medium-size skillet and heat over medium-high heat. Line a plate with a couple of paper towels. When the oil is hot, add the tortilla strips in batches and fry, stirring often, until they are crisp and lightly colored, about 2 minutes. Remove with a slotted spoon to the plate, and sprinkle lightly with salt while they are still hot.
