Cheesy Baked Mexican Lasagna Casserole is the kind of dinner that disappears fast the second it hits the table. It has all the comfort of a baked pasta dish, but with bold taco-style flavor, layers of tortillas, seasoned beef, salsa, beans, and plenty of melty cheese in every bite.

It is hearty enough for a family dinner, easy enough for a weeknight, and flexible enough to adjust with what you already have in the kitchen. Once baked, the layers hold together beautifully, making it a satisfying casserole that feels both cozy and crowd-pleasing.

Why Is Cheesy Baked Mexican Lasagna Casserole So Good?

This casserole works because every layer brings something to the pan. The tortillas soften as they bake and create that familiar stacked texture, while the meat filling stays rich and savory. Salsa adds moisture and flavor, beans make it more filling, and the cheese on top pulls everything together with that golden, bubbly finish everyone loves.

Another reason it is such a favorite is how adaptable it is. You can make it spicier, swap in shredded chicken, add corn, or top it with sour cream, cilantro, sliced jalapeños, or diced avocado before serving.

How To Make the Cheesy Baked Mexican Lasagna Casserole

Step 1: Prepare the oven and baking dish

Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish with nonstick cooking spray so the casserole lifts out more easily after baking.

Step 2: Cook the beef and onion

Heat the olive oil in a large skillet over medium heat. Add the diced onion and cook for 3 to 4 minutes until softened. Add the ground beef and cook until browned, breaking it up as it cooks. Drain excess grease if needed.

Step 3: Build the filling

Stir in the minced garlic and cook for 30 seconds. Add the taco seasoning and water, then mix well. Stir in the black beans, diced tomatoes with green chilies, salt, and black pepper. Let the mixture simmer for 3 to 5 minutes so the flavors come together.

Step 4: Start layering

Spread a thin layer of salsa on the bottom of the prepared baking dish. Place a layer of tortillas over the salsa, trimming or overlapping as needed to cover the bottom.

Step 5: Add the first full layer

Spoon part of the beef mixture over the tortillas. Add a few dollops of sour cream, spread a little salsa over the top, then sprinkle with some of the Mexican cheese blend and cheddar.

Step 6: Repeat the layers

Continue layering tortillas, beef mixture, salsa, sour cream, and cheese until all ingredients are used, finishing with tortillas, the remaining salsa, and a generous layer of cheese on top.

Step 7: Bake until bubbly

Cover loosely with foil and bake for 20 minutes. Remove the foil and bake for another 10 to 15 minutes, until the cheese is melted, bubbling, and lightly golden.

Step 8: Rest and serve

Let the casserole rest for 10 minutes before slicing. This helps the layers set so each serving holds together better. Top with chopped cilantro before serving.

Best Ways to Serve and Store Cheesy Baked Mexican Lasagna Casserole

Serve this casserole hot with a fresh spoonful of sour cream, chopped cilantro, sliced green onions, or diced avocado. It also pairs well with tortilla chips, a crisp salad, Mexican rice, or roasted corn for a fuller meal.

To store leftovers, let the casserole cool completely, then cover and refrigerate for up to 4 days. Reheat individual portions in the microwave or warm larger portions in the oven at 350°F until heated through. You can also freeze it in tightly wrapped portions for up to 2 months.

Frequently Asked Questions

Can I make Cheesy Baked Mexican Lasagna Casserole ahead of time?

Yes. You can assemble it a day in advance, cover it tightly, and refrigerate until ready to bake. Add a few extra minutes to the baking time if it is going into the oven cold.

Can I use corn tortillas instead of flour tortillas?

Yes, corn tortillas work well and give the casserole a slightly more traditional flavor. They may be a bit more delicate, so layer them carefully.

What protein can I use instead of ground beef?

Ground turkey, shredded chicken, or even a combination of beans and sautéed vegetables all work nicely in this dish.

How do I keep the casserole from getting watery?

Drain the tomatoes well, avoid overly thin salsa, and let the beef mixture simmer briefly before layering. Letting the casserole rest after baking also helps it firm up.

Can I make it spicier?

Absolutely. Use hot salsa, add chopped jalapeños, or stir a pinch of cayenne into the meat mixture.

What cheese works best for this casserole?

A Mexican cheese blend melts beautifully, but cheddar, Monterey Jack, pepper jack, or a mix of all three also taste great.
