  • 2 skinless chicken breasts on the bone (about 2 lbs)
  • 1 tbsp safflower oil
  • 1 large white onion, chopped
  • 1 large green bell pepper, seeded and chopped
  • 1/8 tsp plus 1/2 tsp sea salt, divided
  • 1/2 tsp fresh ground black pepper, divided
  • 1 tbsp ground cumin
  • 2 tsp chile powder
  • 1 1/2 tsp dried oregano
  • 4 cloves garlic, chopped
  • 2 jalapeno chile peppers, seeded and chopped (TIP: If you prefer more heat, keep the seeds in.)
  • 2 cups jarred or boxed unsalted diced tomatoes, with juices
  • 1 cup fresh or frozen corn kernels
  • 1 1/2 cups milk
  • 2 tsp potato starch
  • Olive oil cooking spray
  • 12 6-inch corn tortillas, quartered
  • 6 oz Mexican cheese blend or half Jack cheese and half cheddar cheese
  • 3 scallions, thinly sliced


  1. Poach chicken breasts: Fill a large saucepan about two-thirds full with water and bring to a boil. (: When you add chicken, water should cover chicken breasts by about 1 inch.) Add chicken and as soon as water starts to bubble again, cover and reduce heat to medium-low. Cook at a low simmer, adjusting heat if necessary, until chicken is no longer pink in thickest part and registers 165°F on an instant-read thermometer, 22 to 25 minutes. When cool enough to handle, pull chicken off bones and tear into bite-size pieces. Set aside. (MAKE AHEAD: Complete Step One up to 2 days ahead; cover and refrigerate.)
  2. Preheat oven to 350°F. In a large skillet on medium-high, heat oil. Add onion, bell pepper, 1/8 tsp salt and 1/4 tsp black pepper. Cook for 12 to 15 minutes, stirring occasionally, until soft and lightly browned. Add cumin, chile powder and oregano and stir to combine. Add garlic and jalapeno and cook until garlic softens, stirring frequently, about 1 minute. Add tomatoes and bring to a simmer. Stir in corn and cook until heated through, about 1 minute. Reduce heat to medium-low.
  3. In a small bowl, stir together about 2 tbsp milk and potato starch until combined; stir in remaining milk. Add to skillet and bring to a simmer, stirring constantly until slightly thickened, about 1 minute. Stir in chicken and cook until heated through, about 1 minute. Season with remaining 1/2 tsp salt and 1/4 tsp black pepper. Remove from heat.
  4. Mist a 9 x 13-inch baking dish with cooking spray. Arrange half of tortillas over bottom of dish, overlapping slightly. Top with half of chicken mixture, then sprinkle with half of cheese. Add a second layer of tortillas, chicken and cheese. Cover with foil and bake until liquid is bubbling and cheese is melted, 35 to 45 minutes. Rest for 5 minutes. Sprinkle with scallions.
