Ingredients

  • 2 lbs boneless, skinless chicken breasts or thighs
  • 2 cups enchilada sauce (red or green)
  • 10 corn tortillas, cut into strips or quarters
  • 2 cups shredded cheddar or Mexican blend cheese
  • 1 can black beans, drained and rinsed (optional)

Instructions

  1. Spray inside of the slow cooker with nonstick spray.
  2. Season chicken with salt, pepper, and taco seasoning. Place in the bottom of the slow cooker.

  4. Remove chicken, shred with two forks, and return to the slow cooker.
  5. Stir in black beans, corn, and green chiles if using.
  6. Layer tortilla strips over the chicken mixture, then pour remaining enchilada sauce over the top and stir gently.
  7. Sprinkle shredded cheese evenly over the top.
  8. Cover and cook on low for 30–45 more minutes until cheese is melted and bubbly.
  9. Let rest 10 minutes before serving. Garnish as desired.

Notes

  • Add sliced jalapeños or olives for extra flavor.
  • Mix in sour cream or cream cheese for a creamier texture.
  • Use salsa verde and Monterey Jack cheese for a green enchilada variation.
  • Can use rotisserie chicken for a faster version—skip first cook step.
  • Freezes well in individual portions for meal prep.
