How Do You make Chicken Fajita Casserole?
Making chicken fajita casserole is easy! Here’s how to make it:

- When the pan is hot, brown the chicken on each side for about 2 minutes per side. When it’s brown on each side, remove it and set aside on a plate.
- Add in the onion, pepper, garlic, and jalapeño to the pan. Sauté for 2 minutes or until translucent.
- Move the pan off the heat and add in the frozen brown rice, Greek yogurt, ¼ cup cheese, 1/2 tablespoon taco seasoning, salt and pepper. Stir together then place the chicken breasts on top.
- Cover with foil and bake at 400 degrees for 25-27 minutes or until the chicken is 165 in the center.
- Remove the foil and add the remaining ¼ cup of cheese. Turn the oven to broil and broil until the cheese is melted and starting to crisp.
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 on the dry goods aisle if you can’t find them. Just don’t cook them first. Take them straight from the bag and add to the pan.
WW Note: The only points in this recipe are from the brown rice (20) and cheese (8). You can use low fat cheddar cheese to save 1 SP per serving.
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 blend, 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

Is chicken fajita casserole easy to store?
Yes, this chicken fajita casserole is easy to store.

Reheating: This Chicken Fajita Casserole tastes great when reheated! You can reheat in the microwave, in the oven set at 350°F until the center is warmed through, or sauté on the stove.
It’s best to store this casserole in the refrigerator and enjoy fresh.

So good! Easy to make, super delicious, and really filling!

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!

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! 😉
