Can I make chicken enchilada casserole ahead of time?
Yes. Assemble it up to 24 hours ahead, cover, and refrigerate. When baking from cold, add 10 to 15 minutes to the covered bake time, and bake until it is hot in the center and bubbling around the edges. If it looks dry on top, splash on a couple extra tablespoons of sauce before it goes in.
What tortillas work best, corn or flour?
Corn tortillas give you a more classic enchilada vibe and hold up nicely in sauce. Flour tortillas bake softer and more tender, almost like a creamy layered bake. Both work. Use what your family actually eats. For easiest layering in a 9x13, look for 6-inch corn tortillas or street-size flour tortillas.
How do I keep it from getting soggy?
Two things help: do not drown every layer, and bake it covered first so it heats through, then uncover at the end so the top dries slightly and the cheese browns. Also, let it rest 10 minutes before cutting. Hot casserole is basically lava soup until it calms down.
Can I use rotisserie chicken?
Absolutely. Rotisserie chicken is the weeknight cheat code. Pull it while it is still warm, shred it, and keep some darker meat in the mix for extra juiciness.
Is this spicy?
It depends on your enchilada sauce. Most store-bought red enchilada sauces are mild to medium. If you want more heat, add diced jalapeño, a pinch of cayenne, or use pepper jack in the cheese mix.
How do I know it is done?
You want it bubbly at the edges, the cheese melted and lightly golden, and the center hot all the way through. If you like a number, aim for 165°F in the middle.
