This well-seasoned King Ranch chicken casserole is a big family favorite. You can put the tasty Tex-Mex casserole together earlier in the day, then cover and refrigerate until you're ready to bake. Make the dish with chicken breasts or chicken thighs, or use a combination of both.

This dish is open to all kinds of variations. Feel free to replace one of the cans of condensed soups with 1 cup of sour cream, or, if you aren't a fan of mushrooms, use all cream of chicken soup or half cream of celery. Instead of using all cheddar cheese, use a combination of cheddar and Monterey Jack cheese, or use part pepper jack cheese for a spicier topping. If you don't have a can of tomatoes with green chiles (Ro-Tel or similar), substitute with plain diced tomatoes and a small can of chopped green chile peppers. The casserole may be made with flour tortillas as well.

Serve with a tossed salad for an uncomplicated and fabulous family meal.

Glass Bakeware Warning

For premade casseroles or leftovers that are in a glass baking dish and have been refrigerated, do not place directly into a hot oven as the glass can shatter. Instead, place any cold glass bakeware into a cold oven to warm up while it preheats. Or, allow the bakeware to rest outside of the fridge for 30 minutes to reach room temperature while the oven preheats.

Tips

  • To cook the chicken, put it in a large saucepan or Dutch oven and cover with water. Bring to a boil, reduce the heat to low, and cover the pan. Simmer for about 10 to 15 minutes, or until just thoroughly cooked. When the chicken is cool enough to handle, cut it into chunks.
  • Make it ahead: The day before or several hours in advance, prepare the casserole layers. Cover the baking dish tightly with foil and refrigerate the casserole. Take the casserole out of the refrigerator about 30 minutes before baking. Increase the baking time by about 10 to 15 minutes.

Recipe Tips

  • Add about 4 to 6 ounces of sautéed sliced mushrooms to the sauce mixture.
  • Add a 2-ounce can of sliced ripe olives (drained) to the sauce mixture, or sprinkle them over the top of the casserole.
