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.
