A flavorful, satisfying chicken tortilla casserole is the perfect family meal for any night of the week. Most of the preparation can be done a day in advance, so all you'll have to do is pop it in the oven about an hour before it's time to eat. The casserole starts with cooked shredded chicken breasts. Poach or bake the chicken breasts in advance, or use your instant pot to cook the chicken quickly. Or use the chopped or shredded meat from a purchased roasted or rotisserie chicken. Another great thing about this casserole is its versatility. Make it spicier with some cayenne or hot chile peppers, or swap out the chicken and make it with leftover turkey. Add some corn or sliced black olives to the layers or add some rinsed canned black beans. Not only is this hearty one-pot meal a tasty choice for a family dinnerit's an excellent dish to take along to a potluck dinner or party. The casserole is a complete meal, but you might want to serve it with some sliced tomatoes or fresh salsa to brighten the plates. Or make a simple tossed salad to go with dinner.
