Chicken Tortilla Casserole

This is the make-ahead casserole that quietly does its best work in the fridge overnight. Torn corn tortillas, shredded chicken breast, and a creamy sauce of green chili salsa and cream soups get layered with cheddar, then left to rest a full day before baking.

That rest is the secret, not a shortcut. As the dish sits, the tortilla pieces soak up the sauce and soften into tender, almost enchilada-like layers, so it bakes up cohesive and creamy rather than dry and crumbly.

The salsa brings a gentle green-chili warmth, the two soups make it rich and saucy, and the cheddar melts through every layer. It is a smart landing spot for leftover roast or rotisserie chicken.

Bake it covered to heat through, then pull the lid for the last stretch so the top browns and bubbles.

Pro Tips

• Don’t skip the overnight rest; that is what softens the tortillas and melds the flavors.
• Uncover for the final stretch to get a golden, bubbling top instead of a pale one.
• Let it sit a few minutes after baking so the layers set and serve in neat squares.

Variations

• Use Monterey Jack or a Mexican cheese blend in place of, or alongside, the cheddar.
• Stir diced green chilies, black beans, or corn into the chicken mixture.
• Swap the green chili salsa for a roasted red or a spicier salsa to change the heat.
