This south-of-the-border casserole combines tender chicken, corn tortillas, and creamy soup in layers that meld together overnight in your fridge, creating something that’s fundamentally the comfort food equivalent of a warm hug from your abuela.
The beauty lies in its simplicity – you’re fundamentally making a Mexican lasagna without all the fussy layering techniques that make you question your life choices halfway through.

Ingredients List
Getting this Mexican-Style Border Chicken on your table starts with gathering some pretty straightforward ingredients that you probably already have lurking in your pantry.
- 4 large cooked chicken breasts
- 12 corn tortillas
- 1 (10 3/4 ounce) can cream of mushroom soup or 1 (10 3/4 ounce) can cream of celery soup

Health considerations to keep in mind:

- You could lighten things up by using reduced-fat versions of the soups and cheese, though you’ll sacrifice some of that rich, indulgent flavor.

- Consider serving it with a fresh salad or some roasted vegetables to add more nutrients to your plate.

Substitutions and Variations
• Dairy alternatives – The milk can be swapped for chicken broth if you want less richness, or use half-and-half if you’re feeling indulgent.
Because sometimes we all need a little extra comfort in our comfort food.
• Veggie boost – Sneak in some diced bell peppers or corn kernels between the layers for extra color and crunch.
Additional Things to Serve With This Dish
This hearty casserole is basically a Mexican-inspired hug on a plate, so you’ll want sides that complement without competing for attention.
- Mexican rice – The classic pairing that soaks up any extra sauce and adds that perfect grainy texture contrast.
- Simple black beans – Either from a can (no judgment here) or slow-cooked with cumin and garlic, they bring protein and earthiness to balance all that creamy richness.
- Fresh guacamole and chips – Because what’s a Mexican-style meal without the holy trinity of avocado, lime, and salt?
- Crisp romaine salad – Dressed with lime vinaigrette to cut through the cheese-heavy main dish, plus it makes you feel like you’re being healthy.
- Warm flour tortillas – For the people who want to turn every bite into a soft taco, which honestly sounds pretty genius.
- Pickled jalapeños or hot sauce – Some folks need that extra kick, and this dish plays well with heat even though it’s comfort food at heart.
Cooking Tips & Tricks (Chef’s Notes)
After making this dish more times than I care to admit, I’ve picked up a few tricks that’ll save you from the mistakes I wish someone had warned me about.
- Don’t skip the 24-hour cooling time – I know it’s tempting to rush straight to the oven, but that overnight rest lets all those flavors meld together like they’re meant to be, plus the tortillas soften just enough without turning to mush.
- Use rotisserie chicken for maximum laziness – Why make your life harder when the grocery store deli counter has already done the work, and honestly, that pre-seasoned chicken adds extra flavor depth.
- Cut your tortilla squares with kitchen shears – Way faster than a knife, and you won’t end up with those weird uneven chunks that bake at different rates.
- Mix half the cheese into the soup mixture – This creates little pockets of melted goodness throughout instead of just having all the cheese on top where it might brown too much.
- Keep that extra milk handy during baking – Casseroles are sneaky little things that can go from perfectly creamy to sadly dry in the span of 15 minutes, so check on it every 30 minutes or so.
- Let it rest for 10 minutes after baking – Otherwise you’ll have a sloppy, sauce-everywhere situation that looks nothing like the neat squares you were hoping for.
- Use the deepest casserole dish you own – This recipe makes a lot, and shallow dishes lead to overflow disasters that your oven will never forgive you for.

Fun “Did You Know?”
Did you know that corn tortillas have been a staple food in Mexican cuisine for over 9,000 years?
I find it fascinating that this simple flatbread predates wheat tortillas by thousands of years. The ancient Aztecs and Mayans considered corn sacred, calling it the “flesh of the gods.”
What’s really interesting is that traditional nixtamalization – the process of treating corn with lime – actually increases the nutritional value by making niacin more bioavailable.
When you’re layering those tortilla squares in this casserole, you’re using an ingredient that’s literally shaped civilizations. That’s some serious culinary history on your plate!
