What is Dorito Casserole?

Doritos Chicken Casserole is a fun twist on the classic taco casserole. But the addition of crunchy Dorito chips takes this dish to a whole new level.

In our house, taco casserole is a staple. Everyone loves tacos; however, sometimes, I don’t want all the fuss (or mess!) of making individual tacos and prepping all the toppings. This is why casseroles are amazing!

They’re the ultimate comfort dish with all flavors of a family favorite but in one convenient pan!

This quick and easy meal has all the makings of the perfect comfort food main dish. Made with tender chicken, tomatoes, crunchy chips, smothered in a zesty, creamy, sauce and topped with a healthy portion of gooey cheese; this casserole is soul-satisfying!

So, when you want to change up your traditional Taco Tuesday routine or are just looking to spice up your weeknight dinner menu, rotate in this simple creamy Chicken Doritos Casserole, it is sure to become a dish the whole family will love!

Ingredients Needed

Chicken – This recipe starts with cooked chicken. So, cook the chicken prior to using or for an easier meal prep or use a rotisserie chicken from the store.

Sour Cream – Feel free to use a low fat or fat free version of your favorite brand.

Rotel – If you don’t have a can of this you can use a drained can of diced tomatoes and a small can of chopped green chilies.

Corn – Use canned corn. Drain and rinse before using.

Cream Soup – I use cream of chicken soup, but feel free to use cream of mushroom if you’d prefer.

Powdered Fiesta Ranch Dressing – While I love the zesty flavor this dressing adds to the dish, feel free to use original if you’d prefer a milder flavor.

Dorito Chips – I love using Nacho Cheese flavor Dorito chips but Spicy Nacho, Cool Ranch, or Spicy-Sweet Chili would be delicious as well. Or even try a combination of two!

Cheese – I like the flavor of Mexican blend with the zesty ranch dressing and the Doritos but use your favorite or what you have on hand. Cheddar cheese or Colby Jack taste great too!

How to make Doritos Chicken Casserole

First: Preheat oven to 350 degrees F and spray a 9×13-inch cooking spray. Set aside. In a large mixing bowl, combine the chicken, sour cream, Rotel, cream of chicken soup, corn, and fiesta ranch dressing.

Second: Add a handful of the crumbled chips to the bottom of the prepared baking dish.

Third: Spread the meat mixture over the initial layer of chips. Top mixture with larger pieces of crushed-up chips. Sprinkle with shredded cheese.

Fourth: Place foil over the pan and bake for 20-minutes. Remove foil and bake for an additional 5-minutes. Remove from oven and sprinkle with remaining Doritos chips.

How to Store Leftovers

Store any leftovers in an airtight container in the fridge for up to 5 days. Reheat individual portions in the microwave or larger portions in the baking dish in the oven.

Can I freeze it?

You can freeze, unbaked Doritos Casserole. Prepare according to recipe card, prior to baking.

Tightly wrap casserole in foil and place in freezer for up to 2 months. When ready to enjoy, allow casserole to thaw overnight in fridge. Once thawed, bake according to recipe card.

Can I make this with ground beef?

Sure can! Feel free to swap the chicken for 1 pound of ground beef. If you use leaner beef, you might need a little oil in the pan when browning the meat.

Can I turn this Doritos Chicken Casserole into Walking Tacos?

Sure can! Prepare chicken mixture per recipe card. Then, slightly crush your individual bags of Doritos to make room for the filling. Add 1/4 cup of the chicken casserole to each bag, layer with favorite toppings and enjoy!

Tips for No Leftovers

  • You can cook the chicken before using in the recipe or for easier prep, use a rotisserie chicken from the deli. I like to keep cooked chicken breasts in the freezer for just this purpose.
  • I prefer shredded chicken in this dish but cubed works well too.
  • You can put the cheese before the chips if you want your chips to stay a little crunchier.
  • Top with your favorite taco toppings: sour cream, salsa, diced tomatoes, cilantro and jalapeños.
  • To crush Doritos or tortilla chips, place in a Ziplock bag and crush by hand, but do not crush too small.
  • Spray foil with cooking spray prior to covering so it doesn’t stick to the cheese
  • Taco seasoning would be tasty in this dish if you’d like to swap out for the ranch.
  • For added protein, add in drained kidney or black beans
  • Be sure to drain the can of corn prior to adding into chicken mixture
