Ingredients

  • 3 tablespoons butter
  • 3 tablespoons all-purpose flour
  • 2 cups chicken broth
  • 1 (4 ounce) can chopped green chilies
  • 1 (4 ounce) can sliced black olives
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon dried oregano
  • 1/8 teaspoon chipotle chile powder
  • 3 skinless, boneless chicken breast halves
  • 1 cup sour cream
  • 12 (6 inch) corn tortillas, cut into bite-size pieces
  • 1 cup shredded Colby-Jack cheese, or to taste

Method

  • Melt butter in a large skillet over medium heat. Stir in flour; cook for 1 minute. Whisk in chicken broth; cook and stir until sauce is smooth and thickened, 2 to 3 minutes.
  • Stir green chiles, olives, salt, oregano, and chipotle chile powder into the sauce. Add chicken breasts and bring to a simmer. Reduce heat to low, cover, and cook until chicken is no longer pink in the center and the juices run clear, about 15 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
  • Remove chicken from the skillet, leaving heat on low. Place chicken on a plate; shred into bite-size pieces.
  • Stir sour cream into the sauce. Return chicken to the skillet; add tortilla pieces. Stir until combined and top with Colby-Jack cheese. Cover and cook until bubbly and melted, 5 to 8 minutes.
