Recipe FAQs
Why do you use frozen onion in this recipe?
There are several reasons why I recommend using frozen onion in this Mexican chicken casserole recipe. First, frozen diced onion and frozen diced green pepper are great things to have in the freezer in a pinch. And second, use frozen because it cooks through faster and with this relatively short cooking time you’ll need them to cook faster. Using raw onions throws the casserole texture way off. Trust me, I have ruined a casserole or two before I figured this out.
Can chicken casserole be made ahead of time?
You can definitely assemble this chicken casserole recipe and store it tightly covered in the fridge for up to three days. It might just need another 5 to 10 minutes of baking time when it comes straight from the cold fridge.
Is this chicken casserole gluten-free?
Yes, this Mexican chicken casserole is gluten-free. Just make sure you double-check you’re using a gluten-free can of cream of chicken soup and that no other ingredients have sneaky gluten additions.
Can I make my chicken casserole in a crockpot?
Yes, you can definitely cook this Mexican casserole in the slow cooker. Mix all the ingredients together and cook in the slow cooker on low for 4 to 5 hours. I recommend adding the remaining shredded cheese about an hour before it’s done.
What do you serve with your Mexican chicken casserole?
While this is a substantial and hearty main meal in itself, you could also serve your casserole with your favorite taco toppings, like salsa, Pico de Gallo, salsa verde, , green onions, guacamole and corn chips, and jalapeños. Another option is a simple green salad or some fresh green beans.

I didn’t drain the rotel, was I supposed to? It’s watery, what do I do?
I wanted to know same thing do I cook the instant rice first or add all together
Hey Lashawn! You add it uncooked. Hope this helps!
Just made it ohh my goodness , its delicious, my picky eater kids love it, thanks Christy!!
I am so glad to hear that everyone liked it Lashawn!!!
This may be a silly question, but I may have missed it in the directions somewhere. Is the instant rice precooked before mixing everything together, or do you add uncooked instant rice?
What side dish would u suggest for this recipe?
Julie I usually serve it with a salad and some bread. I have also served it with green beans. It is good just the way it is too! I have made this SO many times over the past two months. It is a budget friendly delicious meal. Chicken is cheap and I usually buy the cheese when it goes on sale BOGO to cut down a little on the expense. Everything else is stuff I usually already have.
I am not a big casserole person but my husband is – he grew up on them so I decided to try this a few weeks ago. It was AWESOME! The first time I made it I followed the instructions exactly and then added some crushed potato chips to the top (my husband asked for them). It was SO good. Tonight I sauteed some onions because I didnt have frozen and left off the chips because I am out – it smells so good. This is going to quickly become a staple in our house. Even my picky daughter devoured it
Made this last night followed recipe exactly except used Rotel with Green Chilis. It came out very runny and was not a hit in our house. Will not make it again.
I am so sorry it didn’t turn out well for you Tara.
Made this last weekend for dinner with friends and it was great. I made a spanish rice so I did not add rice to the casserole therefore, I used less broth, about a cup. Make sure to drain the rotel and use less broth if you are not adding the instant rice.
This was delicious and perfect for a church potluck. I sauteed an onion and a green pepper instead of using frozen but everything else I did the same.
I am so glad it was a hit Vicki!!
