FAQs
Can I use flour tortillas instead of corn tortillas?
Yes, you can substitute flour tortillas, but they may make the casserole softer and less authentic in flavor. Corn tortillas hold up better during slow cooking.
What if I don’t have a slow cooker?
You can layer the ingredients in a baking dish and bake at 350°F for about 45 minutes to an hour, until the chicken is cooked through and cheese is melted.
