This fusion casserole brings together the best of Mexican and Italian cuisines. Layers of soft flour tortillas alternate with seasoned shredded chicken, black beans, and a velvety sour cream sauce. Three types of cheese create a golden, bubbly topping that's irresistible.
The preparation comes together quickly—just 25 minutes of active time before baking. The creamy sauce, made with sour cream, cream of chicken soup, and spices like cumin and paprika, keeps everything moist and flavorful.
Perfect for feeding a family or meal prepping for the week, this hearty dish serves six generously. Let it rest for 10 minutes before slicing to ensure clean, beautiful layers.
The first time my sister-in-law brought this to a potluck, I honestly thought she'd made two separate dishes and accidentally stacked them. Then I took a bite. Something about the way the creamy sauce melts into the tortillas while the taco seasoning creates this incredible savory base just works. My kids now request it for birthday dinners instead of regular lasagna.
Last winter when my brother came home from college, he walked through the door and immediately asked if I was making taco lasagna. Apparently my sister-in-law had raved about it enough that he needed to try it himself. We stood around the counter eating straight from the pan while he told us about his semester. Those messy, standing-up dinner moments are some of my favorites.
Ingredients
- 3 cups cooked chicken breast, shredded: Rotisserie chicken works perfectly here and saves so much time on busy weeknights
- 1 medium onion, diced: Yellow onions become sweet as they sauté, adding depth to every layer
- 2 cloves garlic, minced: Fresh garlic matters more here than in many recipes since it builds the base flavor
- 1 red bell pepper, diced: These add little pockets of sweetness and bright color throughout the casserole
- 1 (15 oz) can black beans, drained and rinsed: They make the dish more filling and add protein without changing the flavor profile
- 1 (4 oz) can diced green chiles: Optional, but they provide this gentle heat that keeps things interesting
- 2 cups sour cream: This is the secret to that restaurant-style creamy texture
- 2 cups shredded cheddar cheese: Sharp cheddar gives you that classic taco flavor punch
- 1 cup shredded Monterey Jack cheese: Monterey Jack melts beautifully and creates those gorgeous cheese pulls
- 1 (10 oz) can condensed cream of chicken soup: I know it's processed, but it makes the sauce foolproof and delicious
- 1/2 cup whole milk: Whole milk keeps the sauce rich and prevents separation
- 2 tablespoons taco seasoning: Homemade or store-bought both work, just adjust salt accordingly
- 1 teaspoon ground cumin: Cumin is what makes it taste like tacos instead of just chicken and cheese
- 1/2 teaspoon paprika: Mostly for color, but it adds a subtle earthy note
- 1/2 teaspoon black pepper: Freshly ground makes a noticeable difference here
- 1/2 teaspoon salt: Start with half and add more at the end if needed
- 12 small flour tortillas: The soft taco size works best and you can cut them to fit your pan
- 2 tablespoons olive oil: For sautéing the vegetables until they're perfectly soft
- Fresh cilantro: The bright herb flavor cuts through all that rich cheese and cream
Instructions
- Get your oven ready:
- Preheat to 375°F and grease a 9x13-inch baking dish with butter or cooking spray
- Sauté the vegetables:
- Heat olive oil in a large skillet over medium heat, cook onion and red bell pepper for 3-4 minutes until softened, then stir in garlic for just 1 minute until fragrant
- Build the taco filling:
- Add the shredded chicken, black beans, green chiles, and taco seasoning to the skillet, mixing well and cooking for 2 minutes to let the spices bloom
- Make the creamy sauce:
- Whisk together sour cream, cream of chicken soup, milk, cumin, paprika, salt, and black pepper in a large bowl until completely smooth
- Start layering:
- Spread a thin layer of sauce on the bottom of your dish, arrange 4 tortillas overlapping as needed to cover the surface
- Add the first filling layer:
- Spread half the chicken mixture over the tortillas, drizzle with a third of the sauce, sprinkle with a third of each cheese
- Repeat the layers:
- Add another tortilla layer, remaining chicken mixture, another third of sauce, and another third of cheeses
- Finish it off:
- Top with remaining tortillas, remaining sauce, and remaining cheeses
- Bake covered:
- Cover tightly with foil and bake for 25 minutes to heat everything through
- Get that golden top:
- Remove foil and bake another 10 minutes until cheese is bubbling and starting to turn golden brown in spots
- Let it rest:
- Wait 10 minutes before slicing so the layers set up and don't slide everywhere when you cut
- Garnish and serve:
- Scatter fresh cilantro over the top and serve while still hot and bubbly
My daughter asked if we could have this for her actual birthday dinner this year instead of going out to a restaurant. When your kid chooses a home-cooked casserole over a restaurant meal, you know you've found something special. We lit candles on a slice of lasagna instead of cake.
Making It Your Own
I've experimented with so many variations of this dish. Adding corn kernels between layers brings sweetness. Swap in pepper jack for half the cheddar when you want more heat. Sometimes I throw in a can of diced tomatoes with green chiles instead of plain green chiles. The basic structure works with whatever you have on hand.
Make-Ahead Magic
This might be the ultimate make-ahead meal. Assemble it completely, cover tightly with foil and refrigerate for up to 24 hours before baking. Add about 10 minutes to the covered baking time if it's coming straight from the fridge. I've also frozen it unbaked for those nights when dinner needs to happen with zero effort. Just thaw overnight and bake as directed.
Serving Suggestions
A simple green salad with lime dressing cuts through all that rich cheese. Sliced avocados on the side feel fancy but take zero effort. Cold beer or crisp white wine balance the spices perfectly.
- Serve with extra hot sauce on the table for the heat seekers
- Sour cream dollops on top add even more creaminess if that's your thing
- Crushed tortilla chips sprinkled over each bowl add the best crunch
Some dishes are just recipes, but this one has become part of our family story. Hope it finds its way into your regular rotation too.
Recipe Q&A
- → Can I make this ahead of time?
-
Yes, assemble the entire dish up to 24 hours in advance and refrigerate. Add 5-10 minutes to the baking time if baking straight from the refrigerator.
- → What can I use instead of flour tortillas?
-
Cooked lasagna noodles work beautifully for a more traditional Italian feel, or use corn tortillas for a gluten-free option.

-
Store in an airtight container in the refrigerator for 3-4 days. Reheat individual portions in the microwave or cover with foil and warm in a 350°F oven.
- → Can I freeze this casserole?
-
Absolutely. Wrap the unbaked casserole tightly in plastic wrap and foil, then freeze for up to 3 months. Thaw overnight in the refrigerator before baking.
- → How can I make it spicier?
-
Add chopped jalapeños to the chicken mixture, use pepper jack cheese instead of Monterey Jack, or increase the taco seasoning to 3 tablespoons.
- → What sides pair well with this?
-
A crisp green salad with citrus vinaigrette balances the richness. Chilled Sauvignon Blanc or light Mexican lager also complement the flavors beautifully.
