King Ranch Chicken Casserole

I was recently asked to try the New and Improved PAM® formula. PAM is a product I use all the time and wondered how the new formula would compare in this King Ranch Chicken Casserole.
It can be so frustrating to work on making a delicious dish only to have it stick to the pan. Not only does this make it hard to serve, but you also lose some of the meal to the pan and end up having to soak and scrub for clean-up.

PAM’s new formula is designed to prevent food from sticking on your dishes and make clean up a breeze. The New and Improved PAM® formula has been found to be 70% better at attacking food that is baked on vs. bargain cooking sprays.
As a food blogger, I need every meal be picture-perfect. Plus, I would love to have more time to enjoy my food and spend less time soaking, scrubbing, and cleaning in the kitchen. So, I picked a gooey, cheesy, stick-to-the-pan casserole to put the new formula to the test.
King Ranch Chicken Casserole
I made a King Ranch Chicken Casserole. This consists of layers of corn tortillas, creamy chicken mixture, and cheese (the ultimate baked on culprit). Armed with the new PAM, I went into battle.
The casserole itself was a family pleaser, and the new PAM left me a winner with hardly any clean up. There was no need for soaking or scrubbing. No casserole left sticking to the pan. In fact, there is hardly anything left in the pan.
Put your toughest recipes to the test and watch as PAM comes to the rescue! No matter what meal you’re cooking, PAM helps you pull it off. Even better.

Instructions for King Ranch Chicken Casserole
Begin by preheating your oven to 325°F and preparing your baking dish. To do this, spray a 9×13-inch dish with non-stick cooking spray, making sure to coat it evenly. This crucial step ensures that your casserole won’t stick to the dish, making both serving and cleanup much easier.Set it aside for later use.
Next, move on to preparing the filling. In a large mixing bowl, combine the canned soups and Ro*Tel tomatoes. Stir the ingredients until they completely blend into a smooth mixture. After that, add the chicken and sliced green onions to the bowl. Mix thoroughly so the ingredients are evenly distributed, creating a flavorful filling.
Once your filling is ready, it’s time to assemble the casserole. Begin by tearing half of the tortillas into bite-sized pieces and spreading them across the bottom of the prepared baking dish. This forms the base layer of your casserole. Afterward, evenly distribute about 2 cups of the chicken mixture over the tortilla pieces, making sure to spread it out to cover the entire layer. Then, sprinkle 3/4 cup of shredded cheese over the chicken mixture, making sure each layer balances with flavor and texture.
Continue assembling by repeating the layering process two more times. First, tear and layer the remaining tortillas, followed by spreading the chicken mixture evenly, and finally topping it with shredded cheese. These layers create a wonderfully cheesy, hearty casserole that is full of flavor.
Finally, place the baking dish into your preheated oven and bake for 40 minutes, or until the casserole is hot and bubbly. As it bakes, the cheese will melt beautifully, creating a golden, slightly crisp topping. Once it’s done, let it cool slightly before you serve. This easy-to-make dish is a guaranteed crowd-pleaser, perfect for feeding 6-8 people. Enjoy every bite of this creamy, cheesy, and satisfying casserole!

Frequently Asked Questions
Can I use a different type of meat?
Absolutely! While shredded chicken is traditional, you can use turkey, ground beef, or even rotisserie chicken for convenience. Just ensure the meat is fully cooked before adding it to the recipe.
Can I make this casserole ahead of time?
Yes! You can assemble the casserole up to a day in advance. Cover it tightly with plastic wrap or foil and fridge. When ready to bake, let it sit at room temperature for about 15-20 minutes before placing it in the oven.
Can I make this recipe spicy?
Definitely! If you like heat, opt for the spicy version of Ro*Tel tomatoes, or add some diced jalapeños, chili powder, or a sprinkle of cayenne pepper to the chicken mixture.
Can I use flour or corn tortillas?
This recipe works best with corn tortillas, as they hold up better and add authentic flavor. However, you can experiment with flour tortillas if you prefer a softer texture.
What toppings pair well with this dish?
Top with chopped fresh cilantro, diced avocado, sour cream, or a squeeze of lime juice to enhance the flavors even more. These toppings add a fresh and vibrant contrast to the creamy casserole.
