Quick Overview

How do I make a Mexican Chicken Casserole? If you’re making tortillas, you’ll layer the chicken mixture, and more cheese in a baking dish. Bake it until it’s bubbly and golden brown, and you’re done! What is the best part about using rotisserie chicken?

Ingredients

For the Chicken:
* 2-3 boneless, skinless chicken breasts (about 1.5 pounds), cooked and shredded. I prefer poaching them for extra tenderness, but rotisserie chicken works great too!
* 1 tablespoon olive oil
* 1 onion, chopped
* 1 bell pepper (any color), chopped
* 1 (15-ounce) can of corn, drained
* 1 (15-ounce) can of black beans, rinsed and drained.
* 1 (10-ounce) can of diced tomatoes and Green Chilies (like Rotel), undrained.
* 1 packet taco seasoning (or homemade – see notes below)!
* 1 teaspoon cumin
* ½ teaspoon chili powder
* Salt and pepper to taste

What is Creamy Sauce?
* 1 (10.75-ounce) can condensed cream of chicken soup.
* 1 cup sour cream (or Greek yogurt for a healthier option – I’ve tried it, it’s great!)
* 12 cup milk (I’ve even used almond milk in a pinch and it’s been delicious!)
* 1 (4-ounce) can diced green chilies, undrained
* 1 cup shredded cheddar cheese, divided

For the Casserole:
* 6-8 flour tortillas (I prefer the medium size)
* 2 cups shredded cheddar cheese (or a Mexican blend), divided into 4 equal portions.

What is the step-by-

Step 1: Preheat & Prep Pan

Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish. I usually use cooking spray, but you can also grease it with a little bit of olive oil or butter. This helps prevent the casserole from sticking and makes it easier to clean up later.

Step 2: Cook the Chicken and Veggies

If you are using rotisserie chicken, heat olive oil in a large skillet over medium heat. Add the chopped onion and bell pepper and cook until softened, about 5-7 minutes. This step is important because it brings out the natural sweetness of the onion and pepper, which adds depth of flavor to the casserole.

Step 3: Add Chicken, Beans, Corn, and Seasonings

Add the shredded chicken, corn, black beans, diced tomatoes and green chilies, taco seasoning, cumin, chili powder, salt, and pepper to the skillet. Stir to combine. I always taste the mixture and adjust the seasonings as needed. Stir to combine and cook for another 5-10 minutes, until heated through. Sometimes I add a little extra chili powder for a spicier kick.

Step 4: Prepare the Creamy Sauce

In a large bowl, combine the condensed cream of chicken soup, sour cream, milk, diced green chilies, and 12 cup shredded cheddar cheese. Mix well until everything is smooth and creamy. I like to use a whisk to make sure there are no lumps in the sauce.

Step 5: Assemble the Casserole

Spread a thin layer of the creamy sauce on the bottom of the prepared baking dish. Then, place 2-3 tortillas on top of the sauce, overlapping as needed to cover the bottom of the dish. Spread half of the chicken mixture over the tortillas, then sprinkle with 12 cup of shredded cheese. Repeat the layers: tortillas, remaining chicken mixture, 12 cup of shredded cheese. Top with remaining tortillas and spread the remaining creamy sauce evenly over the top. Finally, sprinkle with the remaining 1 cup of shredded cheese.

Step 6: Bake

Bake in the preheated oven for 25-30 minutes, or until the cheese is melted and bubbly and the casserole is heated through. I usually check it after about 20 minutes to make sure the cheese isn’t getting too brown. If it is, I loosely cover the casserole with foil for the remaining baking time.

Step 7: Cool & Serve

Let the casserole cool for a few minutes before slicing and serving. This helps the layers set and makes it easier to cut. Garnish with your favorite toppings, such as sour cream, guacamole, salsa, or chopped cilantro.

What should I serve it with?

This **Mexican Chicken Casserole** is pretty hearty on its own, but it’s even better with some delicious side dishes! The coolness of the salad balances out the richness of the casserole. If you want something more substantial, try serving it with some Spanish rice or refried beans. What are some good side dishes to serve with guacamole and tortilla chips? For a party or potluck, I like to set up a topping bar with a variety of options, such as sour cream, salsa, guacamole, chopped cilantro, diced tomatoes, and sliced green onions. My family tradition is to have this with a side of elotes (Mexican street corn) – it’s the perfect complement! And honestly, sometimes I just grab a fork and eat it straight from the baking dish – no sides needed!

What are some of the best ways to make Mexican Chicken Casserole?

I’ve made this **Mexican Chicken Casserole** countless times, and I’ve learned a few tricks along the way. First, don’t overcook the chicken! Why do I prefer poaching the chicken in a casserole? If you add too much chicken mixture, the layers will be too thick, and the casserole won’t cook evenly. I’ve learned this the hard way! When layering the tortillas, make sure to overlap them slightly to prevent any gaps. This will help keep the filling from leaking out. I also recommend using good quality tortillas. If you want to add a little extra flavor, try sautéing some chopped garlic with the onion and bell pepper. What are some of the best cheeses to try? I sometimes add a little cream cheese to the chicken mixture to make it extra creamy. I tested this with pepperjack last month and it was wonderful. It added a bit more of a kick. Can you bake it covered with foil for the first 15 minutes and then uncovered for the last 10-15 minutes to get the cheese nice and bubbly without burning the tortillas?

What are some Storing and Reheating Tips?

Can you make this Mexican Chicken Casserole ahead of time? If you have leftovers, add a few extra minutes to the baking time to ensure it’s heated through. Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, simply microwave individual portions or bake the entire casserole in a preheated oven at 350°F (175°C) until heated through. For longer storage, you can freeze the casserole for up to 2-3 months. Wrap it tightly in plastic wrap and then in foil to prevent freezer burn. I prefer to add cheese after freezing because it adds freshness and helps with flavor loss. Thaw it in the refrigerator overnight before reheating. The only problem is to remember to do so!
