Dorito Chicken Casserole

A bubbling, creamy chicken filling sits beneath a cap of Doritos and melted cheddar. Scoop through the layers for saucy comfort and a salty crunch in the same bite.

This Dorito Chicken Casserole is creamy, cheesy, and layered with crunchy Doritos, tender chicken, and savory Tex-Mex flavor in every bite! Baked until hot and bubbling with browned cheesy edges and crisp chip pieces across the top, it’s an easy crowd-pleasing casserole that works especially well for family dinners and casual gatherings.

Granny’s Kitchen Notes

From Betty Lou Gardner

I leave a few bigger chip pieces because they stay crunchier once everything bakes together. The browned cheesy corners around the edges are always the first part people go after.

How to Make Dorito Chicken Casserole

◆

Condensed soups, diced tomatoes with green chilies, milk, and finely diced onion stirred together in a large vintage mixing bowl.

01

Mix the Sauce

Stir together the condensed soups, tomatoes with green chilies, milk, and onion until creamy.

Cooked shredded chicken folded into a creamy soup and tomato sauce in a large vintage mixing bowl.

02

Add the Chicken

Fold the cooked chicken into the creamy sauce until evenly coated.

03

Layer the Casserole

Alternate lightly crushed Doritos, chicken filling, and cheddar cheese, leaving some larger chip pieces for texture.

04

Bake Until Hot and Bubbling

Cover and bake, then uncover near the end until the cheese is melted, the edges are bubbling, and the center reaches 165°F.

05

Serve with Toppings

Let the casserole rest briefly, then top individual servings with sour cream, avocado, cilantro, salsa, shredded lettuce, or lime as desired.
