This King Ranch chicken casserole is the ultimate Texas comfort food that combines creamy layers with a mild Southwestern kick. It’s a low-effort, high-reward dinner that uses smart pantry shortcuts to get a kid-approved meal on the table in no time.
In a large skillet over medium heat, sauté bell peppers in olive oil until softened.
Make the sauce while peppers are cooking. To a large bowl, add diced tomatoes (plus juice from can), green chilis (plus juice from can), soup (plus ½ can water), sour cream, chili powder, garlic powder, cumin, and cayenne pepper; mix until well combined.
Add the cooked peppers to the bowl and thoroughly mix; then add ½ cup of this sauce mixture to the bottom of a well greased 13x9 casserole dish.
Next, arrange ½ of the chicken (1&½ cups) over the sauce, followed by ½ of the remaining sauce and then 1 cup of the shredded cheese. Arrange ½ of the cut corn tortillas on top (it's okay if they slightly overlap).
Start a new layer by placing the remaining chicken on top of the tortillas, followed by 1 more cup of cheese; then place the remaining tortillas on top.
Spread the rest of the sauce over the tortillas and top with the remaining cheese.
Bake, uncovered, for 35-40 minutes or until bubby and top is light golden brown.
Allow to rest for 5-10 minutes before slicing and serving. Garnish with diced green onions if desired.
Notes
For the best texture, don't skimp on the sautéing step for your peppers. Getting them nice and soft before they go into the casserole ensures you don't end up with any crunchy surprises in an otherwise creamy dish.Let the casserole sit for about 10 minutes after taking it out of the oven. This gives the sauce time to set so your layers stay nice and neat instead of sliding all over the plate.Store casserole leftovers in an airtight container for up to 3-4 days; keep refrigerated.You can also freeze it in a freezer-safe container or wrap tightly with foil for up to 3 months; defrost overnight in the fridge.To reheat, warm individual portions in the microwave or reheat the whole dish in the oven (loosely covered with foil) at 350°F until bubbling.
