Cheesy One-Pan Mexican Chicken Casserole

This easy Mexican Chicken Casserole is a beloved family recipe—ideal for busy weeknights, make-ahead freezer meals, or serving to guests. Layers of torn flour tortillas, cooked chicken, a creamy salsa sauce, and melted cheddar create a comforting, flavorful dish that’s simple to assemble and bakes up beautifully.

I first made this casserole years ago and it quickly became a repeat favorite. It’s just as good baked right away as it is assembled and frozen for later—making it a convenient option for meal prep. When cooking for two, I divide the recipe into smaller pans so we can enjoy one now and freeze one for another night. For company or larger families, a single 9×13-inch pan serves nicely.
