SUBSTITUTIONS FOR CHICKEN FAJITA CASSEROLE
Rice: You can find frozen brown rice in the freezer section at most grocery stores. I usually get mine from Walmart or Trader Joe’s. Do not use dry rice products. Do not use white rice. The brown rice holds texture. Frozen rice works best here, but you can also use the 90 second bags of rice in the dry goods aisle if you can’t find them. Just don’t cook them first. Take them straight from the bag and add them to the pan. We haven’t tried quinoa or any other grain in this recipe so I don’t know how it will work.
Jalapeño – Jalapeño is optional, omit it for less spice.
Chicken Breasts– Chicken breasts can be subbed with chicken thighs or chicken tenders
Beans – Beans would make a great addition to this meal. Black beans or pinto beans would work best.
Taco Seasoning– I recommend using our homemade Taco Seasoning, it’s lower in salt. You can also use store bought taco seasoning.
Low salt – This can easily become a high sodium meal. We recommend omitting the salt if you’re using store bought homemade taco seasoning or this will be much higher in salt. We used our homemade taco seasoning which is much lower in salt.
Cheese – Mexican, cheddar, or pepper jack cheese all work in this recipe. You can also omit the cheese.
Garlic: If you don’t have fresh minced garlic, substitute with 1 teaspoon garlic powder.
Onion: If you don’t have fresh onion, substitute with 1 teaspoon onion powder

So good! Easy to make, super delicious, and really filling!
Berni says
I ordered my groceries online for this so I received 2 lbs. of chicken. I don’t cook so I felt like this was going to be hard to make for me, but this was actually super easy. The chicken took the full amount to cook since I had to stack the 2lbs of chicken, but now I have lunch for the whole week. It smells delicious and tastes so good. I did forget the salt and pepper (whoops) but I can add that when I warm up my meal. Thanks for another great meal idea, Liz!
The Clean Eating Couple says
So glad you liked it Berni! Thank you!
Griff Neilson says
Wow, the brown rice really does give this a great texture and deep flavor. This one is a keeper because healthy casseroles have become an oxymoron but this one is certainly the exception. Thank you so much for this one! 😉
The Clean Eating Couple says
So glad you liked it, Griff! Thank you so much!
Tayler says
We love this casserole! Can you substitute frozen cauliflower rice?
The Clean Eating Couple says
I haven’t tried making it with frozen cauliflower rice but I think it would result in a mushy mess. If you are going to try it, I would use raw cauliflower rice instead of frozen because it will be less watery, but I honestly don’t think it will come out very good. If you try it let me know!
Lyndi Zavy says
This was a HUGE hit for my family (2 kids 3 & 8 and my husband, all fairly picky!). It was super easy and so flavorful, we even fought over the leftovers the next day. This is definitely going into our weekly rotation!
The Clean Eating Couple says
Thanks, Lyndi!!
Shawna Camden says

We haven’t tried quinoa or any other grain in this recipe so I don’t know how it will work.
Ethel Sweed says
can I used chicken thighs instead of breasts? What brand of organic taco seasoning do you prefer?
Taylor says
This was delicious!!! I couldn’t find frozen brown rice (only had time to check Aldi) but used a 90 second quinoa/brown rice mix like the substitutions suggested. It was so good! I can’t stand Greek yogurt and was a little nervous about using it, but happy to report I couldn’t taste it at all!! My husband was a huge fan, too. Adding it to our meal rotations- thank you!
Jenny says
Super tasty and easy to make! Used frozen bell pepper, onions and tossed in some frozen corn and black beans. Also, used the frozen rice medley from Trader Joe’s and it came out wonderful!
Lily says
Love this recipe – made it over the summer and it was great! Could you do all the steps for this recipe except the baking a day ahead and bake the next day?
The Clean Eating Couple says
I wouldn’t recommend it, think the rice would get a funny texture. You could maybe sear the chicken/saute the veggies ahead of time, but I think you’re better off to bake it and reheat it when ready to serve
Hannah Garcia says
We have a dairy allergy in our home. I have a hard time finding a cheese for Mexican dishes. Mykonos works great for Italian dishes. Do you have anything you recommend to make this dairy free?
The Clean Eating Couple says
I haven’t tried making this dairy free! If you’d like to try dairy free yogurt and cheese feel free and let me know how it comes out! or if you just skip the dairy I’m sure it would also be fine. good luck 🙂
Anita says
I’m not familiar with frozen brown rice. Is it already cooked? Could you use instant brown rice instead or regular brown rice.
