Creamy Chicken Tortilla Soup

Langkah-langkah

1. In a large pot, heat the oil and butter over medium heat. Add the onions, garlic, and green pepper and cook, stirring occasionally, until tender and just starting to brown, about 15 minutes. (Turn the heat to medium-low if the mixture is browning too quickly.)
2. Add the flour and cook, stirring constantly, for 1 minute. Add the chicken broth, cut tortillas, cumin, chili powder, salt, and cayenne and bring to a boil. Turn the heat down to low and simmer, uncovered, for 15 minutes.
3. Remove the pot from the heat, then use a handheld immersion blender to purée the soup until completely smooth. (Alternatively, let the soup cool slightly and use a blender to purée in batches. Be sure to remove the center knob on the blender top and cover with a dish towel to avoid splatters.) Taste and adjust seasoning, if necessary. Stir in the chicken, if using, then ladle the soup into bowls and serve with optional additions.
