How to Make Chicken Fajita Casserole

Recipe Notes
- Cooking Vegetables – The peppers and onions are a little crunchy in this recipe and I love it that way but if you prefer softer veggies, sauté them for 3-5 minutes in oil before mixing them in with the other ingredients.
- Cooking Casserole – We cook the casserole covered with foil to prevent the top from burning.
- Rotisserie Chicken – This is a great recipe to use leftover cooked chicken or rotisserie chicken.
- Low Carb – You can substitute the regular white rice with cooked cauliflower rice or serve the casserole over the cauliflower rice.
- Add Beans or Corn – This makes for a heartier casserole.
- Extra Creamy – Add a block of softened cream cheese.

This was a great casserole my whole family loved it!
Happy to hear you loved it — thanks so much!
This was absolutely delicious! I will definitely be making this again and again! (I did not have salsa on hand so I substituted it with one can of mild Ro*Tel and used brown rice in place of the white rice.) Thank you for this wonderful recipe!
Lynn – Wahoo! So glad you enjoyed it and made it your own! Thank you for leaving a comment.
Made this today and every time loved it. Also, there’s enough to freeze for another meal.
Cynthia – That’s great! Thank you for letting us know!
This looks great! I made your chicken enchilada casserole last week and it was wonderful. For this recipe, can I cut the chicken into pieces or would it ruin the consistency? Thanks!
Lisa – I’m so happy you tried and loved the Chicken Enchilada Casserole last week. I hope you enjoy this Chicken Fajita Casserole just as much. Yes, you can cut the chicken into pieces. Let me know how it turns out.
I’m confused. One of the Notes says you can use leftover or rotisserie chicken.
But the recipe doesn’t say to cook the chicken first.
Betty – Yes, that’s correct. I cook the chicken in this recipe but you can use shredded cooked chicken as well – It will not dry out while baking and will still taste delicious in this recipe! So either way works.
The recipe did not state whether you are supposed to cook the chicken first. I’ve had mine in the oven for 45 minutes now, and the chicken is still raw. I’m hoping for the best because it took a lot of ingredients that I don’t want to waste. It does smell delicious.
We always have tons of leftovers, but, not with this dish. Everyone had seconds and wanted more. The dish was scraped clean. So easy to make and delicious! This will be one of my staple meals from now on. Thank you!
Woohoo Monti! I love hearing this! I’m so glad everyone enjoyed it so much! Thank you for sharing and for the positive review!
My kids are obsessed with this recipe.
Sounds delicious. But I have looked at other recipes for chicken fajitas and they cook the chicken first. Do you need to cook the chicken first in this recipe?
Judy – I did not bake the chicken first. It cooks in the casserole when baking. I hope you try it out and let me know what you think!
