Ingredient Substitutions: You can swap out the chicken for turkey breasts or use a mix of chicken thighs for extra juiciness. Optional Variations: For a spicy kick, add some diced jalapeños or a splash of hot sauce to the creamy sauce. Storage or Reheating Tips: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or on the stovetop, adding a splash of milk if the sauce thickens too much.
