Ingredients

For the Soup:

  • 1 medium yellow onion finely chopped
  • 2 garlic cloves minced
  • 1 tablespoon extra virgin olive oil
  • 3 cups reduced-sodium chicken stock
  • 1 can 8 oz tomato puree
  • 1 can 14.5 oz diced fire-roasted tomatoes
  • 1 can 4.5 oz mild green chiles
  • 1/4 cup fresh cilantro coarsely chopped
  • 4 cups shredded cooked chicken rotisserie or pre-cooked
  • 2 tablespoons taco seasoning blend
  • 1 can 11 oz sweet corn, drained and rinsed

For the Tortilla Strips:

  • 2 burrito-sized flour tortillas
  • 2 cups canola oil for frying
  • 1 tablespoon taco seasoning

Optional Garnishes:

  • Chopped fresh cilantro
  • Sliced jalapeños
  • Reduced-fat shredded cheese
  • Light sour cream

Instructions

  • In a medium skillet, warm the olive oil over medium-high heat. Sauté the chopped onion and minced garlic for about 3 minutes, or until the onion softens slightly but retains a bit of bite.
  • Transfer the sautéed aromatics to your slow cooker. Add in the chicken broth, tomato sauce, diced tomatoes, green chiles, corn, cooked chicken, cilantro, and taco seasoning. Mix thoroughly to combine.
  • Secure the lid and cook on high for 2 to 3 hours or on low for 4 to 5 hours, until the soup is thoroughly heated and the flavors have melded.
  • While the soup is nearing completion, prepare the crispy tortilla strips. Heat the canola oil in a saucepan over medium-high heat.
  • Using a sharp knife or pizza cutter, slice the tortillas into thin, half-inch-wide strips.
  • Fry the tortilla pieces in small batches, turning occasionally, until golden and crispy—approximately 2 to 4 minutes per batch. Remove with a slotted spoon and place on a paper towel-lined plate to drain.
  • While still hot, dust the tortilla strips with taco seasoning and a light sprinkle of salt. Set aside to cool and crisp fully.
  • To serve, ladle the hot soup into bowls and top with tortilla strips. Add any optional garnishes such as cilantro, jalapeños, sour cream, or cheese according to preference.

Notes

For a milder flavor, substitute regular diced tomatoes for fire-roasted ones. Adjust seasoning levels to taste and serve with lime wedges if desired for a citrusy finish.
