Getting Ready to eat chicken fajita casserole

One genre of recipes that I have really grown to enjoy since I moved to the United States is casseroles. You won’t find very many casseroles in Mexico, so it was a new experience for me here. 

At first I wasn’t sure how I would feel about them, but I really enjoy them now! What I love most about them is how easy they are to prepare. Usually, you just need to have a variety of ingredients that you mix together, and then bake them. My family loves the casseroles I have made in the past, and this chicken fajita casserole is no exception. 

What are Fajitas?

I really like fajitas. They can be made with steak, chicken, shrimp and more and they are just so good.

In general, you make fajitas by grilling some type of meat, along with onions and peppers. You then fill a tortilla with the meat and veggies, and add cheese, sour cream, pico de gallo, and salsa.

How Do You Make Chicken Fajita Casserole?

Even though I love fajitas, sometimes there isn’t time to make the traditional version. That is why I love to make this chicken fajita casserole on busy nights, and my family loves it! 

For chicken fajita casserole, you will use similar ingredients that you use for traditional chicken fajitas. For example, you will use chicken, peppers, onions, and cheese. The difference is that you will combine all of those ingredients in a baking dish and bake them instead of cooking them separately.

The resulting flavors are amazing and you can eat them with all of the standard fajita garnishes or just by itself. 

Using Perdue Farms Chicken for The Casserole

It is important for me to use high quality ingredients for this recipe. Since the chicken is the star of the recipe, I decided to use PERDUE® Harvestland® Boneless Skinless Chicken Breast Tenderloins and they worked perfectly. I didn’t even have to cut them into smaller pieces, because they were the perfect size. 

I love the size of these tenderloins, because they defrost quickly so you don’t have to wait long to start cooking. They are 99% fat free as well and have no added hormones, steroids, or antibiotics. I used these tenderloins, and the chicken came out super tender, juicy and flavorful.

If you haven’t heard about Perdue Farms, I suggest you check them out. They just launch a direct-to-consumer site, so you can buy their delicious meat packages and have them shipped directly to your home.

This was delicious. The baking dish was wiped clean. Not a bite was left. Very tasty. I love veggies and chicken. I served over rice and used sour cream on top. Next time I will make Guacamole to go with it.

We had a girls night out and it was a Mexican themed dinner. It was the first time I ever made this dish. It was a hit! I should have taken a picture of it because there wasn’t much left. I’m definitely making this again. It was so good and good for you!!! Thank you for the recipe!

These look SO good! What would you suggest serving alongside this dish?

Should this be covered in the oven?

@Pmom, I am wondering the same since the cheese is dark brown and the cook time isn't accurate at all, as I have just added more time after cooking at 400 for 30 min
