Here is another variation of this type of casserole.
At some point in time, I have made this casserole.
First, a little history:
King Ranch is the largest ranch in the United States. At some 825,000 acres
https://en.wikipedia.org/wiki/King_Ranch
It's hard to describe King Ranch casserole to those who've never experienced its deliciousness, but we'll try: It's an ooey, gooey, cheesy, spicy, and oh-so satisfying combination of pantry staple ingredients you probably already have on hand.
King Ranch chicken is a Tex-Mex casserole with unknown origins, though it's assumed the dish is named after King Ranch, Texas. The casserole consists of pulled chicken, canned soup, green chiles, corn tortillas, sour cream, veggies, and lots of cheese.
Ingredients
1 tablespoon vegetable oil
1 medium white onion, diced
1 medium red bell pepper, diced
1 medium green bell pepper, diced
1 (10.5 ounce) can condensed cream of mushroom soup
1 (10.5 ounce) can condensed cream of chicken soup
1 (10 ounce) can diced tomatoes with green chile peppers (such as RO*TEL®)
1 cup chicken broth
2 tablespoons sour cream
2 teaspoons ground cumin
1 teaspoon ancho chile powder
½ teaspoon dried oregano
¼ teaspoon chipotle chile powder
1 (3 pound) cooked chicken, torn into shreds or cut into chunks
1 (8 ounce) package shredded Cheddar cheese
10 (6 inch) corn tortillas, cut into quarters
Note:
Tortillas
Use corn tortillas cut into quarters. Some reviewers use Doritos or tortilla chips for a fun, crunchy twist.
Directions
Preheat the oven to 350 degrees F (175 degrees C).
Heat oil in a large skillet over high heat. Saute onion and bell peppers in the hot oil until warmed through, about 2 minutes. Transfer to a large bowl.
Add both cans of condensed soup, diced tomatoes with chile peppers, chicken broth, sour cream, cumin, ancho chile powder, oregano, and chipotle chile powder; mix until sauce is well-combined.
Spread a few tablespoons of sauce in the bottom of a 9x13-inch baking dish. Layer with 1/2 of the chicken, 1/2 of the sauce, 1/2 of the Cheddar cheese, and 1/2 of the tortillas.
Spread the remaining chicken over the tortillas. Spread all but 1/2 cup of the remaining sauce over the chicken, then top with another 1/3 of the Cheddar, and the remaining tortillas. Spread the remaining 1/2 cup over top, and sprinkle with the remaining Cheddar.
Bake casserole in the preheated oven until bubbling, about 40 minutes.
Turn on the broiler and broil until the top is golden, 2 to 3 more minutes.
