This tortilla casserole is essentially a Mexican-style lasagna that uses corn tortillas in place of noodles. The filling is a mix of corn, black beans, tomatoes, green chiles, scallions, spices and cheese. It's an easy, satisfying 30-minute vegetarian dinner made mostly with pantry and freezer staples.

This Mexican Lasagna was my first encounter with the genre of quick and easy recipes. It was given to me more than 20 years ago by my neighbor Nava Atlas, a vegetarian cookbook author and blogger.
She gave me her cookbook, pointed me to her favorite recipe in the book, and told me she loved it because it was easy, delicious and most of the ingredients were things I probably already had in my house. I was sold! I had three active, hungry little boys to cook for and not a lot of time to do it.
Ingredients for Mexican Lasagna
I've made this casserole countless times since then. It's saved me on many busy nights when I wanted a healthy, satisfying dinner without a lot of fuss. My kids, my husband and I loved it back then and we still love it today. It's one of those easy, universally loved recipes that everyone needs in their repertoire.
Black beans – Canned black beans make this recipe especially easy. Drain and rinse them before using.
Tomatoes – Canned diced or stewed tomatoes both work well here.
Green Chilies – A small can of mild chopped green chilies adds lots of flavor without making the casserole spicy. Feel free to use spicy chilies if you want some heat.
Corn – I usually use frozen corn, which can go right into the filling once it's defrosted. When corn is in season and you're not pressed for time, fresh corn cut from the cob is even better.
Scallions – These add fresh onion flavor to the filling. Save a handful to sprinkle over the finished casserole.
Spices – Chili powder, cumin and oregano give this tortilla casserole its classic Tex-Mex flavor.
Corn Tortillas – These take the place of noodles in this Mexican-style lasagna, and create the layers of the casserole.
Cheese – I like Monterey Jack, but cheddar also works. Use your favorite cheese or even a Mexican cheese blend. What's important is to use shredded cheese so you can spread it evenly over the layers for melted cheesiness in every bite.
How To Make Mexican Lasagna
This dish is incredibly easy to put together. For the prep you're mostly just opening cans and measuring spices — the only thing you have to chop is the scallions. The assembly is quick and pretty fun, too. Here's the basic process:
Make the filling: Combine the black beans, tomatoes, green chilies, corn, scallions and spices in a large bowl.

Assemble the casserole: Arrange a layer of corn tortillas in the bottom of a 9 x 12 (or so) rectangular baking dish, overlapping them slightly and trimming them as needed to fit.


Top with half the filling and half of the shredded cheese.
Repeat the layers: Add another layer of tortillas, followed by the remaining filling and cheese.


Bake: Bake the tortilla casserole until it's hot and the cheese is melted and bubbling.

Cut it into squares and serve it with salsa and sour cream and chopped scallions.

Make This Ahead of Time
You can assemble the entire dish several hours ahead. Cover and refrigerate it until you're ready to bake it. Add about 5 minutes to the cooking time if you're baking it straight from the fridge.

Instructions
Preheat oven to 400ºF and set an oven rack in the center position. You will need a roughly 9 x 12 inch rectangular baking dish.
- Combine beans, tomatoes, chilies, corn, scallions, chili powder, cumin, oregano and salt in a large bowl.
- Lightly oil the casserole. Line the bottom with 6 tortillas, allowing them to overlap in the middle. Trim the round edges so they fit squarely against the edge of the casserole. Scoop on half the bean mixture. Sprinkle half the cheese on top. Add another layer of tortillas, followed by the remaining tomato and bean mixture and cheese.
- Bake 15-20 minutes, or until the casserole is heated through and the cheese is bubbling.
- Cut into squares, top with the reserved chopped scallions, and serve with salsa and sour cream or yogurt.
Notes
- Use your favorite chili powder blend or use chipotle chili if you want to amp up the flavor and spice or ancho if you want to keep the heat level mild.
- 6-inch corn tortillas will work well here in a 9 x 12 baking dish but you can truly use any size tortillas and any size casserole, and trim the tortillas down to fit into your pan.
- The casserole can be assembled several hours ahead and kept covered in the fridge until ready to bake. Add 5 minutes onto the cooking time if baking it directly from the fridge.

Andrea
We loved this. I used a Mexican cheese blend, and it was perfect.
Lisa
Great! I'm so glad you enjoyed!!
Marisa
I made this recipe and was very exited about it but the tortillas ended up being soggy and not good at all. Thought maybe I did something wrong but can’t find where.
Lisa
Hi Marisa - I'm sorry you were disappointed with this tortilla casserole. The tortillas in this are like lasagna noodles - they're not meant to be crisp. They're just there to create a layered structure for the Mexican Lasagna and to add delicious corn flavor. I'm wondering if your casserole didn't get completely hot in the oven? It's important for the overall textures and flavors of this dish, to get it nice and hot so juices bubble and the cheese melts.
Sara
I make this several times a month and my tortillas never get soggy. You didn't cook it long enough then
Hilary Lindsey
We make this monthly at our house! It makes for great leftovers and freezes well also.
Alyssa S
This was amazing! I added a little rice into the mixture, and used a packet of taco seasoning instead of the recommended spices. So. Good. Will be making again. ????
beth
New favorite for me, so easy and tasty. I added a half bag of frozen edamame last time I made this, was a nice additional texture/flavor. I've found this freezes well too; I make it on the weekend, slice up and freeze for quick lunch on the run at work.

A family favorite!!! And sooo easy!
Elaine
This was such a hit in my house. I was fortunate enough to find local early fresh corn at my farm market so used kernels from two ears of corn that had been lightly grilled - awesome! I also assembled this the night before, kept in the refrigerator until i got home from work and then popped into the oven. Came out perfect! Great make ahead dish. I think I would increase the seasonings next time though just to give it more oomph. Super delicious recipe - thanks so much!
Lisa Goldfinger
So glad! Thanks Elaine.
Elen
Can you use flour tortillas?
Laura P.
Ellen, I think if you use flour tortillas, you might want to put a layer of cheese on top of the tortillas before adding the bean mixture...maybe that would prevent the flour tortillas from getting too soggy? The corn tortillas are a little more sturdy! Let us know how it turns out. This is one of my favorite recipes!
Lisa Goldfinger
Hi Elen, Interesting question. I've never tried to use flour tortillas. Laura is right - the flour tortillas might get soggy, whereas the corn tortillas just get soft and are a perfect consistency for this dish. I'm thinking the casserole might work really well with lasagna noodles, if you're not concerned with it being gluten free. It sort of is like a lasagna, with the layers and the cheese. I bet that would be really good! If you try it with flour tortillas or lasagna noodles, I'd love to know the results!
Elen
Can you use chicken? Do you have nutrition facts on it? Thanks..
sara
stumbled opon this. making it tonight. sounds way easy and i am a fan of easy cooking.
Laura P.
Hi Lisa,
Thank you for sharing this recipe! My sister asked me to make a vegetarian entree for her son's high school graduation party this weekend. Originally she asked for a half pan, but once I showed her your recipe she said, "we're going to need a full pan of that!". Within minutes she came to me and said it was gone and her guests were literally scraping the pan, even though she also had over 25 lbs of Utica Riggies (a regional dish) and 42 lbs of amazing slow roasted pulled pork with lots of sides. I made it exactly as you described, only multiplied the ingredients to feed a crowd. Ran to the market the next day to buy ingredients for a family get-together and again it was gone in minutes. Thanks for an easy and delicious dish for a crowd!
Lisa Goldfinger
Thanks Laura! I'm so glad your guest enjoyed it. I've never heard of Utica Riggies. Is that a recipe I should try? Lisa
Laura P.
Hi Lisa,
Yes! Try the Utica Riggies...I had never heard of them either until I visited my sister in upstate NY. It is a chicken and rigatoni dish with spices and a vodka-like sauce, minus the vodka! If you google it you will see that there are cook-off competitions and restaurants have their own recipes. Let us know if you try the Riggies!
Tina
Can this tex mex recipe be frozen?
Lisa Goldfinger
Hi Tina. I've frozen leftovers with good success. Best if you transfer it to an airtight container. Lisa
Natalie Slack
I made this last night for my friends and it was so delicious! It's the perfect recipe for a college student just learning how to cook. 🙂
Lisa Goldfinger
Hi Natalie. I'm so glad you enjoyed it. Thanks for letting me know. :)Lisa
Jared
This looks bombbbb, im going to the store to buy the supplies now!!
Barbara Joseph
Perfect timing - Tonight I was going to making my old reliable black beans and rice enchiladas but this will be much more interesting! Thanks for sharing...
Alina
Lisa,
I use to have to engage Brandon to cook with me or else I wouldn't get anything done without his acting out.
Our favorite was homemade chicken nuggets.
I make a version of this tex mex with more layers, but yours is definitely simple and worth trying.
