Spicy Chicken Tortilla Casserole is what I call a Mexican Lasagna. It is spicy chicken with sautéed vegetables and salsa that gets layered between corn tortillas. This is a lovely south of the border casserole. It is sometimes called chilaquiles. This is one of my favourite recipes to cook. This is so easy to make and is filling enough to satisfy hefty appetites after a hard days work. This recipe is normally served on its own as it needs no side dishes. However, a friend always makes a light salad to go with this main dish. All in all a superb recipe ready in 30 minutes.
One of the things I particularly enjoy about this Spicy Chicken Tortilla Casserole is how easily it brings a little excitement to the dinner table. There is something rather satisfying about taking a handful of everyday ingredients and turning them into a dish that looks and tastes so inviting.
When I cook this at home, I like to get everything prepared before I start layering. It makes the whole process much more enjoyable. The combination of chicken, peppers, onions and garlic creates a wonderful base. Meanwhile, the salsa brings everything together with its lovely tomato flavour and gentle heat. As the ingredients cook, the kitchen starts to smell absolutely delicious.
The tortillas are what make this dish particularly interesting. Rather than serving them separately, I use them to create layers throughout the casserole. They soak up some of the flavours from the chicken and salsa, while the cheese melts between the layers. Consequently, every serving has a lovely mixture of textures and flavours. It is a little like enjoying a Mexican-inspired lasagna, but with a character all of its own.
Making It Your Own
I always think recipes should leave a little room for personal preference. For example, if you enjoy plenty of heat, add some chopped jalapeños or a little extra chilli. Alternatively, a milder salsa makes this suitable for family members who prefer gentler flavours.
There are plenty of other ingredients that work beautifully here too. Sweetcorn adds little bursts of sweetness, while black beans provide extra texture and make the casserole even more filling. You could also include red or yellow peppers for extra colour. If you have some leftover roast chicken, that can work wonderfully as well. Just make sure it is thoroughly heated through.
Cheese is another area where you can experiment. Monterey Jack melts beautifully, but Cheddar, mozzarella or a mixture of both can produce equally delicious results. Personally, I enjoy a generous cheesy topping because it gives the finished casserole such an inviting appearance.
Serving and Enjoying
Although this casserole is substantial enough to serve on its own, I sometimes like to put a few simple accompaniments on the table. A crisp green salad provides a refreshing contrast. Similarly, sliced avocado, fresh tomatoes or a little guacamole work particularly well.
For anyone who enjoys entertaining, this is a lovely dish to prepare for friends. You can assemble everything in advance, leaving just the baking until nearer serving time. It also makes a useful family supper when everyone wants something hearty and satisfying.
Most importantly, this is uncomplicated home cooking with plenty of flavour. It is colourful, comforting and wonderfully filling. Once you have tried it, I suspect it will become one of those dependable dishes you return to whenever you fancy something a little different.

Now this is what I call a decent idea for a tortilla. Wish I had found this recipe before.
I topped mine with sliced spring onions and fresh coriander. It looked and tasted wonderful.
Easy to put together and the finished casserole looked impressive on the table.
A great alternative to our usual chicken dinners. Something different without being complicated.
Used leftover chicken from Sunday lunch and it turned into a fantastic Monday evening meal.
Made this for the family last night and everyone went back for seconds. A definite keeper.
Really good recipe. I would perhaps add another pepper for extra colour and sweetness.
The salsa gives this such a wonderful flavour. I might try a homemade version next time.
I found it slightly spicy for the children, so I used a milder salsa. They loved it.
A lovely balance of tomato, chicken and spice. Nothing complicated or difficult to follow.
Lovely flavours throughout. I added a few extra jalapeños for a little more heat.
The layers were delicious, although I would personally use slightly fewer tortillas next time.
A brilliant way to use up leftover roast chicken. It tasted delicious.
The cheese went beautifully golden on top. It was difficult to resist before serving!
Very tasty and filling. A little fresh coriander on top made a nice finishing touch.
I would recommend letting it rest briefly before serving. It makes cutting and portioning easier.
A generous helping of cheese on top makes all the difference. Wouldn’t change a thing.
We enjoyed this with rice and a dollop of sour cream. A really satisfying combination.
Excellent comfort food with a Mexican-inspired twist. I will certainly be making it again.
The leftovers were just as enjoyable the following day. I think the flavours developed overnight.
I added a little smoked paprika and it gave the chicken a wonderful extra depth.
The tortillas absorbed all those lovely flavours. Definitely one of my favourite parts.
The combination of chicken, tortillas and melted cheese makes this a really satisfying dinner.
Lovely and comforting food. Perfect for a chilly evening when you want something hearty.
The spice level was just right for us. Next time I might make it a little hotter.
A little more chilli suited our tastes, but the original version is lovely too.
I used a mixture of Cheddar and mozzarella. The cheesy topping was fantastic.
I added some sliced mushrooms and they fitted in beautifully with the other ingredients.
This has become a regular in our household. Everyone enjoys having something a little different.
I served this with a simple green salad and some guacamole. Absolutely delicious.
A big hit with my teenage children, which doesn’t happen with every meal!
Great recipe for feeding a hungry family without spending ages in the kitchen.
Really enjoyable meal with plenty of flavour. A squeeze of lime before serving was lovely.
Added some sweetcorn and black beans which made it even more substantial.
I added black beans and extra peppers. It made a generous casserole with plenty to go around.
Really enjoyed the different textures in this casserole. The tortillas worked surprisingly well.
A lovely family meal that didn’t take much effort. The whole family approved.
Prepared this ahead of time and baked it when everyone arrived home. Worked perfectly.
My husband loved this and has already asked when we are having it again.
