Ingredients

  • 1 tablespoon olive oil or vegetable oil
  • 1 white onion diced
  • 1 green bell pepper seeded and diced
  • 3 cloves garlic minced
  • 1 teaspoon chili powder
  • ½ teaspoon salt plus more to taste
  • ½ teaspoon black pepper plus more to taste
  • ¼ cup all-purpose flour
  • 2 cup chicken broth
  • 1 cup sour cream at room temperature
  • 3 cup Colby Jack cheese freshly shredded
  • 4 ounces cream cheese softened
  • 3 cups cooked and shredded chicken
  • 1 (10.5 ounce) can Rotel tomatoes
  • 15 corn tortillas

Instructions

  • Preheat the oven to 375 degrees Fahrenheit and spray a large 9×13-inch casserole dish with non-stick cooking spray.
  • Heat the oil in a large skillet set over medium heat. Once the pan is hot and the oil shimmers, add the diced onion and bell pepper and cook until softened, about 5 minutes.

Notes

  • For best results, allow the sour cream and cream cheese to reach room temperature before stirring into the sauce.
  • This recipe can also be made in two 8×8 or 9×9 baking dishes instead of a large 9x13-inch casserole dish. This allows you the option to freeze one for later.
  • You can assemble this casserole ahead of time and refrigerate it for up to 24 hours before baking or freeze it for up to 3 months. 
  • Keep leftovers stored in an airtight container in the refrigerator for up to 4 days.
