Dorito Chicken Casserole with Corn and Creamy Sauce

• Crushed nacho-cheese chips serve as both seasoning and topping, so the casserole gets a big flavor lift from one bag. Reserve half for the finish, because chips stirred into the filling soften quickly.
• The creamy base needs only soup, sour cream, tomatoes, and corn. Those ingredients make a scoopable filling that does not require a separate sauce or a long simmer.
• Three cups of cooked chicken make four hearty servings. Use a mix of light and dark meat, then save any remaining chicken for another dinner later this week.

• 3 cups cooked chicken (420 g)
• 1 can cream of chicken soup, 10.5 ounces (298 g)
• 1 cup sour cream (240 g)
• 1 can diced green-chile tomatoes, drained, 10 ounces (283 g)
• 1 cup frozen corn, thawed (150 g)
• 1 teaspoon chili powder (3 g)
• 1/2 teaspoon ground cumin (1 g)
• 2 cups Doritos nacho cheese chips, divided (120 g)
• 1 1/2 cups grated cheddar cheese, divided (170 g)
• 2 tablespoons sliced scallions (12 g)

Ingredient notes

• Cooked chicken: Three cups make this a practical four-serving casserole. Dark meat stays particularly forgiving after baking, although any plainly seasoned cooked chicken fits the sauce. Cut it into small pieces for even scooping.
• Soup: Condensed cream of chicken soup supplies body without a flour thickener. Choose regular rather than reduced-fat soup for a fuller filling that does not loosen beneath the chip topping during baking in the oven much.
• Tomatoes: Drain diced tomatoes with green chiles thoroughly before mixing. Their brightness cuts the rich sauce, and draining prevents a watery layer beneath the crisp topping after baking at home or reheating later too.
• Corn: Frozen corn brings small sweet bites without extra chopping. Thaw it first and blot away surface moisture, so the filling stays creamy instead of thinning around the chicken pieces while baking in the oven gently.
• Doritos: Nacho-cheese chips season the whole pan, so extra salt is rarely needed. Crush them roughly; fine crumbs disappear, while larger pieces make a more distinct crunchy top layer. Reserve some for the end.

1. 1Heat the oven

   Set the oven to 375°F and lightly grease an 8-inch square baking dish. Put the dish on a rimmed sheet pan if it is very full. This catches stray crumbs and makes moving the hot casserole easier after the cheese melts.

   

2. 2Mix the filling

   Combine the cooked chicken, condensed soup, sour cream, drained tomatoes, thawed corn, chili powder, and cumin in a large bowl. Stir until every chicken piece has a thin coating of sauce. Taste only if your chicken was plainly seasoned, then adjust with a small pinch of salt if needed.

   

3. 3Build the first layer

   Spread half the crushed chips across the prepared dish. Spoon the chicken mixture evenly over them, pressing lightly into the corners. The bottom chips will soften into the filling and help each serving hold together when you scoop it from the pan.

4. 4Add cheddar

   Sprinkle one cup of grated cheddar over the filling. Keep the remaining cheese for the top layer. A divided cheese layer gives the casserole a creamy middle while leaving enough cheddar visible to brown across the chip topping.

5. 5Top the casserole

   Scatter the remaining crushed chips over the cheese, then finish with the remaining cheddar. Leave some larger chip pieces exposed rather than covering every spot with cheese. They toast better and give the finished dish its needed crunch.

6. 6Bake and rest

   Bake uncovered for 25 to 30 minutes, until the edges bubble and the cheddar is melted with light golden spots. Rest the casserole for 10 minutes before serving. That short pause thickens the filling and gives you cleaner, fuller scoops for four plates.

• Drain the tomatoes well, then press them briefly against the colander. Extra liquid is the main reason a creamy casserole turns thin around the edges after baking.
• Use an 8-inch square dish for thicker portions. A 9-inch square pan also works, but the filling spreads wider and the topping browns sooner.
• Crush chips inside their bag with a rolling pin or heavy mug. Aim for mixed sizes, including crumbs for coverage and larger pieces for a more noticeable crunch.
• Let the dish rest before scooping. Ten minutes gives the sauce time to settle, so portions stay together instead of sliding across the plate.

Spoon this casserole beside a crisp romaine salad with lime vinaigrette. Sliced avocado, pickled jalapeños, and extra scallions work well at the table. For a bigger dinner, add warmed black beans or cilantro-lime rice. Four servings make a complete meal with vegetables on the side. The rich filling also fits neatly into flour tortillas for a casual lunch, especially when you have a small portion left.
