Mix your chicken, sour cream, cream of chicken soup, Rotel, seasoning packet, and corn together.
Crunch a few of the chips up and sprinkle on on bottom of pan.
Spread the chicken mixture over the chips in an even layer.
Add the rest of the chips to the top of the chicken mixture.
Cover with shredded cheese.
Bake for 30-35 minutes or until the cheese is melted and the casserole is bubbly on the sides.
Remove and let cool for a few minutes.
Serve warm!
Notes
Drain any wet ingredients thoroughly first. For example, if you used canned corn, then rinse and let it drain completely.
Layer the ingredients properly. If you want those Nacho Doritos extra crunchy, then add them last over the cheese, not under.
Use the right size casserole dish for baking the casserole. The deeper the dish, the more you need to watch out for too much water collecting and making it too soggy. However, too shallow a dish means you have to watch out for over-cooking it too quickly.
Try adding black beans or using Southwest Mexicorn for more flavor.
