I have to admit, this Mexican Dorito Chicken Casserole was a total accident. It started on a random Tuesday when I was staring into my pantry, wondering what I could throw together without making another grocery run. You know those days when even the thought of leaving the house feels like climbing Everest? Yep, that was me.

So there I was, with a bag of Doritos, a can of Rotel, and some leftover chicken giving me the side-eye from the fridge. I thought, Why not layer it all together and see what happens? I wasn’t sure if it would be genius or a complete disaster. Spoiler: it was genius.

The first bite took me straight back to those carefree potlucks growing up, where casseroles were king, and everyone piled their plates with second (and third) helpings. Now, this recipe is a staple in my house. It’s easy, it’s fun, and let’s be honest—who doesn’t love a casserole topped with chips?

Why You’ll Love This Mexican Dorito Chicken Casserole Recipe?

  • It’s ridiculously comforting. Think creamy, cheesy, and crunchy—all in one bite.
  • So easy to make. Even if you’re not a whiz in the kitchen, you’ve got this.
  • Perfect for sharing. Whether it’s a potluck, family dinner, or game night, this casserole feeds a crowd.
  • Totally customizable. Want more spice? Less cheese? (Actually, scratch that—never less cheese!)

Ingredient Notes:

Here’s why every ingredient earns its spot:

  • Chicken Breasts: Tender, shredded chicken is the backbone of this casserole. If you’re short on time, rotisserie chicken works like a charm.
  • Doritos: The MVP of this recipe. Nacho Cheese Doritos add that salty, cheesy crunch we all love.
  • Black Beans: These make the dish heartier and add a bit of Tex-Mex flair. Rinse them well to get rid of any excess sodium.
  • Cream of Chicken Soup: This creates the creamy base that ties everything together. You could also use cream of mushroom or celery for a twist.
  • Rotel Tomatoes: A little heat, a little tang—this is the secret ingredient that wakes up the flavors.
  • Cheddar Cheese: Sharp cheddar melts beautifully and gives the casserole that gooey, cheesy topping.
  • Milk: Just enough to thin out the soup and keep everything moist without being soggy.

How To Make Mexican Dorito Chicken Casserole?

This casserole is so easy, it feels almost too good to be true. Here’s how to make it:

  1. Cook the chicken.
    Preheat your oven to 400°F. Bake the chicken breasts for 20–25 minutes, or until fully cooked. Shred them with a fork when they’re cool enough to handle. Short on time? Grab a rotisserie chicken—no judgment here!
  2. Prep the Doritos.
    While the chicken cooks, crush your Doritos into bite-sized pieces. Not crumbs—think crunchy chunks. Spread half of them in a greased 9×13-inch baking dish to form the crispy base.
  3. Make the sauce.
    In a medium bowl, whisk together the Cream of Chicken soup and milk until smooth. This is your magic sauce that turns everything into creamy, cheesy goodness.
  4. Mix the filling.
    In another bowl, combine the shredded chicken, black beans, and Rotel tomatoes. This is where the Tex-Mex flavors start to shine.
  5. Layer the casserole.
    Spread the chicken mixture over the Dorito layer. Pour half of the soup mixture on top, then sprinkle on a generous handful of shredded cheddar cheese. Repeat the layers: Doritos, chicken, soup, and more cheese (because more cheese is always a good idea).
  6. Bake it.
    Pop the dish into your preheated oven and bake for 20–25 minutes, or until the cheese is bubbly and golden. The smell alone will have everyone running to the table.
  7. Cool and serve.
    Let the casserole cool for a few minutes before serving. This gives everything a chance to set, so you get perfect slices with every scoop.

Storage Options:

Leftovers (if there are any) store beautifully. Keep them in an airtight container in the fridge for up to 3 days. To reheat, pop a portion in the microwave or cover the dish with foil and warm it in the oven at 350°F.

Want to freeze it? Assemble the casserole without the Doritos, wrap it tightly, and freeze for up to 3 months. When you’re ready to bake, thaw overnight in the fridge, add the Doritos, and bake as usual.

  • Vegetarian option. Skip the meat and double up on the beans and veggies.
  • Cheese swap. Try Monterey Jack, pepper jack, or a Mexican blend for a flavor twist.

What to Serve with Mexican Dorito Chicken Casserole?

This casserole is a meal in itself, but here are a few ideas to round it out:

  • A crisp green salad. Something fresh and simple to balance the richness.
  • Mexican rice. Because more carbs = more happiness.
  • Chips and salsa. You can never have too many chips on the table.
  • Cornbread. Sweet, buttery, and the perfect complement to the spicy, cheesy casserole.

Frequently Asked Questions:

Can I make this ahead of time?

Totally. Assemble the casserole without the final Doritos layer, cover it, and refrigerate for up to a day. Add the Doritos just before baking for the best crunch.

Can I use canned chicken?

Absolutely. Just drain and shred it before mixing it with the beans and Rotel. It’s a great shortcut when you’re short on time.

How do I keep the Doritos crunchy?

Add the top layer of Doritos right before baking, and don’t skimp on the cheese—it helps seal in the crunch!

Ingredients

  • 4 boneless skinless chicken breasts, cooked
  • 8 ounces of Doritos chips crushed
  • 1 can of black beans drained and rinsed
  • 2 small cans of Cream of Chicken soup
  • 1 can of Rotel tomatoes and green chilis
  • ¾ cup of whole milk
  • 1 cup of shredded Cheddar Cheese

Instructions
 

  1. Start by preheating your oven to 400°F (200°C). While it's heating up place your chicken breasts in the oven. Bake them for approximately 20 to 25 minutes. This step ensures that the chicken is fully cooked and ready to be incorporated into your casserole.
  2. While the chicken is baking, prepare the Doritos. Crush them into bite pieces. Take half of the Doritos. Evenly distribute them in a baking dish. This layer forms a crispy and flavorful base, for your casserole.
  3. In a bowl combine the Cream of Chicken soup with milk. Mixing these two ingredients together creates a delicious sauce that brings all the flavors together.
  4. Once the chicken is done baking use a fork to shred it into pieces. Mix these shredded chicken pieces with drained and rinsed beans as well as Rotel tomatoes and green chilis. This combination adds a zesty element to your casserole.
  5. Now it's time to layer your casserole. Spread the mixture of chicken, beans Rotel tomatoes and green chilis over the layer of Doritos, in the baking dish. This adds a delicious layer, to your dish.
  6. Pour the creamy soup mixed with milk over the layer of chicken. This adds a comforting touch to the casserole. Don't forget about the cheese! Sprinkle some Cheddar cheese on top for that gooey and cheesy goodness.
  7. To enhance the flavor and texture you'll repeat the layers one time. So another layer of crushed Doritos followed by the chicken mixture, the soup mixture and of course cheese.
  8. Now that all those delicious layers are in place it's time for the bake. Put the baking dish back into the oven again. Let it bake for another 20 to 25 minutes. This baking step ensures everything blends together beautifully resulting in bubbly cheese, on top.
  9. Once the timer goes off your Mexican Dorito Chicken Casserole is ready to be savored. Take it out of the oven. Let it cool down a little before indulging. Each bite will be a combination of textures and flavors. Share this comforting Tex-Mex masterpiece with your loved ones!
