What You’ll Need

Shredded Cooked Chicken
The main ingredient for this casserole is cooked chicken, shredded finely so it mixes easily into the sauce. Rotisserie chicken is an excellent shortcut, but leftover roasted or grilled chicken works just as well.

Nacho Cheese Doritos
These give the dish its signature flavor and crisp bite. Crushed and layered into the casserole, they provide a satisfying contrast to the creamy filling. Swap with another Doritos flavor if you want a different twist.

Cheddar Cheese
Melted cheddar adds richness and brings everything together. You can use a mix of sharp cheddar and Monterey Jack for a softer, creamier texture. Shred your own for the best melt, but pre-shredded works fine for convenience.

Sour Cream
This ingredient adds a tangy creaminess that complements the spices. For a lighter option, plain Greek yogurt is a good substitute and still gives a smooth finish.

Cream of Chicken Soup
This helps form the base of the sauce. If you’d rather not use canned soup, a quick homemade version using butter, flour, chicken broth, and milk works beautifully.

Diced Tomatoes with Green Chilies
These bring acidity, moisture, and a bit of heat. Drain them well before using to prevent the dish from becoming watery. Choose mild or spicy based on your preference.

Taco Seasoning
Essential for that classic Tex-Mex flavor, this seasoning blend brings depth and warmth. Use store-bought or make your own to control salt and spice levels.

Optional Additions:

• Green onions: Sprinkled on top for a pop of color and freshness.

• Black beans or corn: These can be added to the chicken mixture for more texture and flavor.

How to Make It

1. Preheat your oven to 350°F and lightly grease a 9×13-inch baking dish.

2. Crush the Doritos. Use your hands or a rolling pin to break them into small pieces inside a zip-top bag. Don’t turn them to crumbs—just enough to layer.

3. Prepare the filling. In a large bowl, stir together the shredded chicken, sour cream, cream of chicken soup, drained tomatoes with green chilies, taco seasoning, and 1½ cups of shredded cheese. Mix until well combined.

4. Layer the casserole. Start with a layer of crushed Doritos at the bottom of your prepared baking dish. Spoon half of the chicken mixture over the chips and spread it out evenly. Add another layer of Doritos and top with the remaining chicken filling.

5. Add cheese. Sprinkle the remaining cup of shredded cheese over the top layer.

6. Bake uncovered for about 25 to 30 minutes, until the casserole is heated through and the cheese is bubbly and golden.

7. Top and serve. Right before serving, scatter a handful of crushed Doritos over the top for extra crunch, and garnish with green onions if using.

A few pointers:

• Don’t add the final topping of chips too early, or they’ll lose their crispness.

• If your tomatoes are watery, drain thoroughly before mixing.

• Avoid overbaking, as it can dry out the chicken.

Smart Tips & Creative Twists

Spice it up:
Like heat? Add diced jalapeños, crushed red pepper, or hot sauce to the chicken mix. You can also switch to Spicy Nacho Doritos.

Lighter option:
Swap in Greek yogurt, reduced-fat cheese, or use a lighter cream soup version to cut down on calories without losing flavor.

Vegetarian version:
Skip the chicken and use black beans, corn, and sautéed bell peppers instead. Choose a vegetarian-friendly cream soup to tie it all together.

Make it heartier:
Stir in extras like diced bell peppers, corn kernels, or sautéed onions for added bulk and flavor.

Make-ahead friendly:
Assemble the dish ahead of time and refrigerate for up to 24 hours. Add the final cheese and chip topping just before baking.

Freezer tip:
Freeze the unbaked casserole tightly wrapped for up to two months. Bake from frozen, covered, for 45–50 minutes, then uncover and bake another 10–15 minutes.

How to Serve It

Nutrition Notes

While this dish leans toward indulgent, there are easy ways to make it a bit more balanced. Greek yogurt adds protein and reduces fat, while baked chips and reduced-fat cheese can lighten things up.

Adding black beans, corn, or other vegetables increases the fiber and nutritional value. You can also serve smaller portions alongside a veggie-packed side to round out the meal.

It reheats well, so it’s great for leftovers or meal planning.

Common Questions

Can I swap out the Doritos?
Yes, although Doritos add a unique flavor. Plain tortilla chips can work, but you may want to boost the seasoning a bit to compensate.

How should I reheat it?
For best results, reheat in the oven at 350°F for 15–20 minutes. The microwave works too, but the chips won’t stay crispy.

Can I assemble it ahead of time?
Definitely. Put everything together (except the final layer of chips), cover, and refrigerate. Add the topping and bake when ready.

Is there a gluten-free option?
Yes—just be sure to use gluten-free cream of chicken soup, taco seasoning, and check the Doritos label to make sure they’re certified gluten-free.

Can I freeze this dish?
Absolutely. Assemble and wrap it tightly before freezing. When ready to cook, bake from frozen as directed above.

What’s the best kind of chicken to use?
Rotisserie chicken is flavorful and convenient. If using homemade, make sure it’s well-seasoned and shredded for the best texture.

How do I keep the chips from going soggy?
Don’t mix them into the filling. Layer them under and over the creamy mixture and add a final sprinkle just before serving.
