This hearty Mexican-American casserole transforms classic lasagna concepts with authentic Tex-Mex ingredients. Flour tortillas replace pasta sheets, while a savory mixture of browned ground beef, black beans, sweet corn, and diced tomatoes creates layers of robust flavor. The taco seasoning blend brings authentic southwestern spices that permeate every bite, while generous amounts of shredded Mexican cheese blend melt into gooey, golden perfection. Baking creates those coveted crispy edges and warm, bubbling center that make this dish impossible to resist. Perfect for feeding a crowd or enjoying leftovers throughout the week.
The smell of taco seasoning hitting hot beef still transports me back to Tuesday nights when my roommate would whistle through every doorway. We stumbled on this Mexican Lasagna idea completely by accident when we had leftover tortillas and a craving for something baked and cheesy. Now it is the dish everyone requests for potlucks because it is essentially a party in a baking dish.
Last winter I made this for my sister who claimed she hated casseroles until she took her first bite. The way the tortillas soften and soak up all that seasoned beef mixture while the cheese gets golden and bubbly on top changed her mind completely.
Ingredients
- 500 g (1 lb) ground beef: The foundation of the whole dish, brown it well to develop those deep savory flavors
- 1 medium onion, diced: Sweetness that balances the spices and adds aromatic depth
- 2 cloves garlic, minced: Fresh garlic makes such a difference here, do not skip it
- 1 red bell pepper, diced: Brings color and a subtle sweetness that complements the beef
- 1 can (400 g/14 oz) black beans, drained and rinsed: Creamy, earthy, and they hold everything together
- 1 can (150 g/5 oz) corn, drained: Little bursts of sweetness throughout every layer
- 1 can (400 g/14 oz) diced tomatoes: Provides all the saucy moisture the tortillas need
- 1 packet (30 g/1 oz) taco seasoning: The flavor powerhouse that ties everything together
- 1/2 tsp chili powder: Optional but worth it if you like a little extra warmth
- Salt and pepper: Essential for bringing all the flavors forward
- 8 medium flour tortillas: The noodles of this operation, corn tortillas work too if you prefer
- 300 g (3 cups) shredded Mexican cheese blend: A mix of cheddar and Monterey Jack gives you perfect melt and flavor
- Fresh cilantro, chopped: Bright, herbal finish that cuts through the richness
- Sliced jalapeños: For those who want to turn up the heat
- Sour cream: The cool, creamy counterpoint to all those bold spices
Instructions
- Get your oven ready:
- Preheat to 180°C (350°F) so you are ready to bake as soon as everything is layered
- Brown the beef:
- Cook the ground beef in a large skillet over medium heat until nicely browned then drain off the excess fat
- Sauté the vegetables:
- Add the onion, garlic, and bell pepper to the skillet and cook for 3-4 minutes until they soften and smell amazing
- Build the flavor:
- Stir in the taco seasoning, chili powder if using, black beans, corn, and diced tomatoes then let it simmer for 5 minutes
- Start the layers:
- Grease a 22x33 cm baking dish and place two tortillas on the bottom, tear them as needed to cover the surface completely
- Add filling and cheese:
- Spread one-third of the meat mixture over the tortillas and sprinkle with one-fourth of the cheese
- Repeat the layers:
- Layer tortillas, meat mixture, and cheese two more times then finish with tortillas on top and all remaining cheese
- Bake covered:
- Cover loosely with foil and bake for 25 minutes so everything heats through and tortillas soften
- Get it golden:
- Remove the foil and bake another 10 minutes until the cheese is bubbly and starting to turn golden brown
- Let it rest:
- Wait 5 minutes before slicing, this helps the layers set so you get nice clean pieces
My friend's kids now call this taco cake and request it for every birthday dinner. Something about pulling apart those cheesy layers just makes people happy.
Making It Your Own
Ground turkey or chicken work beautifully here if you want something lighter. For a vegetarian version, just add extra beans and more vegetables like zucchini or mushrooms to keep the layers substantial.
Serving Suggestions
A crisp green salad with a lime vinaigrette cuts through the richness perfectly. I love serving this with a light red wine like a Pinot Noir or even a cold beer if it is summer.
Make Ahead Magic
You can assemble the entire dish up to a day ahead and keep it covered in the refrigerator. Just add 5-10 minutes to the covered baking time since it will be cold going into the oven.
- The flavors actually develop more when it sits overnight
- Wrap leftovers individually for the easiest work lunches ever
- Freeze before baking for up to 3 months, thaw overnight then bake as directed
This recipe has saved more weeknight dinners than I can count and never fails to make people feel at home.
Recipe FAQs

Instead of pasta sheets and Italian herbs, this version uses flour tortillas and Tex-Mex seasonings like taco seasoning, chili powder, and cumin. The filling features black beans, corn, and diced tomatoes rather than ricotta and traditional Italian tomato sauce.

-
Absolutely. Assemble the entire dish, cover tightly, and refrigerate for up to 24 hours before baking. You may need to add 5-10 minutes to the baking time if baking cold from the refrigerator.
