Cheesy Mexican Chicken Casserole

Cheesy Mexican chicken casserole is a Tex-Mex pantry-staple bake from the era when condensed soup was a household ingredient and Rotel was the secret weapon in every potluck. Cooked chicken layers with crushed corn chips, a tangy tomato-and-cream-soup mixture, finely chopped onion, and a thick blanket of sharp cheddar on top.

The corn chips on the bottom are the structural genius of this recipe. They soak up the saucy soup mixture during baking, softening into a tortilla-strata-like base while still keeping enough crunch to give the casserole texture. Use sharp aged cheddar, not mild, since the tang stands up to the rich cream soups.

Kitchen Tips

• Shred or chop the chicken into bite-size pieces. Larger chunks make the casserole hard to scoop and leave dry pockets.
• Use Rotel (tomatoes with green chiles), not plain canned tomatoes. The chiles are what give the casserole its Tex-Mex backbone, and plain tomatoes leave it bland.
• Freeze before baking, not after. Assemble in a foil pan, cover, freeze raw, then thaw overnight and bake straight through. Reheating a baked casserole always disappoints.
• Let it rest 10 minutes after baking. Cuts cleaner that way and the saucy layer reabsorbs into the chicken.

Variations

• Stir a can of drained black beans or pinto beans into the chicken layer for extra heft.
• Top with sliced jalapeños or pickled banana peppers for a sharper bite.
• Use crushed tortilla chips or Fritos in place of generic corn chips for slightly different flavor and texture.
