How to Make Easy Chicken Fajita Casserole
You will only be actively cooking, chopping, and mixing for about 20 minutes. Pop the chicken in to bake. And while it's baking saute the veggies. Cooking the vegetables in a skillet helps give this casserole a true fajita flavor. Adding raw vegetables and baking does not yield the same result.
Shred the chicken. Then combine the hot shredded chicken with the veggies, cream cheese, and seasonings.
Put bake in the casserole dish, top with cheese, and bake until bubbly and golden. Serve this chicken fajita bake with a salad or your favorite fajita toppings!
Can I use chicken breasts?
Yes! Just bake the onions and peppers for 10 minutes before adding strips of raw chicken breasts or they can dry out.
What to serve with Easy Chicken Fajita Casserole?
We serve this with taco fixings like sour cream and my Easy Guacamole and a green salad on the side. If you have low carb tortillas you love you can scoop this into those. You can also serve it as a fajita salad right on a bed of lettuce.
Sometimes I make rice and black beans and put them on the side for my kids to make fajita bowls. Growing children need a lot of healthy carbs. And having those on the side helps fill out the meal and stick to our grocery budget.

- Preheat oven to 350. Put the chicken in the casserole dish you will be using for this dish. Cover with foil and bake until cooked to 160 degrees, about 30-35 min. Cool for a few minutes and then shred or chop into bite-sized pieces. Drain any cooking liquid from the casserole dish.
- Meanwhile, in a frying pan coated with cooking spray, cook the pepper and onion over medium-low heat until they are golden and soft. I let mine caramelize the entire time the chicken was in the oven. I just left the heat between low and medium and popped into the kitchen to give them a stir every 5-10 min. Cool until warm.
- In a large bowl mix the cream cheese, half of the shredded cheddar, and the fajita seasoning. Add the chopped chicken and cooked onion and pepper. Put back into the same casserole dish you cooked the chicken in. Sprinkle on the remaining cheese.
- Bake at 350 for 25-30 min until hot and bubbly.
