Mexican lasagna is what happens when taco night and casserole night accidentally become best friends. It has all the stuff you actually want, like seasoned beef, creamy beans, saucy edges, and cheese that stretches just enough to make you feel like you did something impressive. But the method is pure weeknight energy: layer, bake, eat, high five yourself.

Instead of noodles, we use corn tortillas. They soak up flavor, hold their shape, and give you that cozy, slightly chewy bite that feels like enchiladas but stacks like lasagna. The sauce here is a simple mash-up of salsa and sour cream, which bakes into this tangy, creamy situation that keeps everything from drying out.

All the ingredients for Mexican lasagna arranged on a home kitchen counter, including tortillas, ground beef, black beans, salsa, shredded cheese, corn, onions, and spices in small bowls

If you can brown meat and stack layers, you can make this. Also, tasting as you go is not only allowed, it is encouraged.

Why It Works

  • Big flavor, low effort: Taco-seasoned beef plus salsa-sour cream sauce builds depth fast without a long simmer.
  • No soggy layers: Corn tortillas soften but stay structured, especially with a thick filling and a hot bake.
  • Crispy edges and melty middle: Covered bake for tenderness, uncovered finish for those browned cheese spots.
  • Flexible: Swap meat, beans, heat level, and veggies based on what is in your fridge.

Storage Tips

Fridge: Cool completely, then cover the baking dish or transfer slices to airtight containers. Keeps well for 4 days.

Freezer: Wrap individual portions tightly and freeze up to 3 months. Thaw overnight in the fridge for best texture.

Reheat: For the best edges, reheat in a 350°F oven until hot, about 15 to 20 minutes. Microwave works for speed. Add a spoonful of salsa on top if it needs a moisture boost.

Common Questions

Is Mexican lasagna spicy?

It can be, but it does not have to be. Use mild salsa and skip any spicy toppings for kid-friendly vibes. If you want heat, use hot salsa, add chipotle powder, or toss in diced green chiles.

Do I have to use corn tortillas?

Corn tortillas give the best texture and flavor. Flour tortillas work in a pinch, but they tend to get softer and more bready. If you use flour, keep the layers a little thinner and bake uncovered for a few extra minutes to help set it up.

How do I keep it from being watery?

Drain and rinse the beans well, drain corn if using canned, and simmer the beef mixture for a minute or two after adding salsa so extra liquid cooks off. Also, let the casserole rest before slicing.

Can I make it ahead?

Yes. Assemble up to 24 hours ahead, cover, and refrigerate. Bake straight from the fridge, adding about 10 minutes to the covered bake time.

What toppings are good?

All the greatest hits: shredded lettuce, diced tomatoes, pickled jalapeños, avocado, cilantro, extra sour cream, and a squeeze of lime. I also love a quick drizzle of hot sauce right before serving.

I started making Mexican lasagna when I wanted the comfort of a baked pasta dish but did not want to commit to boiling noodles, babysitting sauce, and washing three extra pots. Tortillas were sitting right there like, hey, I can do this job. Now it is my go-to when I need dinner to feel generous, like it could feed friends who “just happen to stop by,” even if it is really just me and my future leftovers.
