Ingredients

This recipe uses basic ingredients you can find in any grocery store! Here's what you'll need:

• Bean - Veggie Filling: This yummy filling is made with a mixture of sautéed onions and zucchini, mixed with black beans, frozen corn, and diced tomatoes with green chilies (like Rotel), seasoned with a mixture of fresh garlic and savory dried spices.
• Ricotta Filling - You'll layer that veggie-bean combo with a delicious cheese layer, made with ricotta cheese (use full-fat for the creamiest results), shredded cheese, fresh garlic, and an egg (which helps hold everything together).
• Picante Sauce - No need to make a special sauce for this recipe. A jar of this tasty salsa is the secret ingredient ... it adds tons of flavor without any fuss!
• Corn Tortillas - This recipe uses corn tortillas instead of lasagna noodles for that Tex Mex twist!
• Shredded Cheese - A final layer of shredded cheese is the perfect ooey-gooey finishing touch! I used a Mexican blend, but you can substitute cheddar, Monterey jack, or similar melty cheeses depending on what you have on hand.

This Meatless Mexican Lasagna recipe is much lighter and healthier than other versions you may have seen (although with all the cheese it's still pretty indulgent), and it's even more delicious! It's also naturally gluten-free (if you have an allergy, always read labels carefully).

Don't be put off by the somewhat long ingredient list. A lot of that is spices and healthy convenience foods. This recipe really is easy to make, I promise!

Picante Sauce vs. Salsa

Picante sauce is a type of salsa. It typically has a smoother, thicker texture than chunkier salsa, which makes it perfect for cooking with!

I used (and would recommend) Pace Picante Sauce for this recipe. It's super tasty and works perfectly here. I used medium (it's not that spicy), but it also comes in mild and hot.

Can't find picante sauce? Feel free to use another jarred salsa, but make sure to choose one with a thicker texture for best results.

You'll Also Need

To make this recipe, you'll also need a large skillet to cook the bean-veggie filling (this Calphalon Frying Pan is my fave!) and a large bowl to mix the ricotta filling. To bake the casserole, you'll need a 9x13-inch baking dish.

How to Make Mexican Lasagna

Ready to start cooking? You'll find a detailed, printable recipe below, but here's a quick overview of the steps:

1. Prepare the black - bean veggie filling. You'll sauté an onion, then add the zucchini and cook until just tender. Stir in the spices, salt, and garlic, then cook until fragrant. Add the beans, tomatoes, and corn, then cook just until hot. Season to taste with salt.
2. Mix ricotta filling. While the vegetables cook, mix together the ricotta, egg, salt, and pepper. Set aside.
3. Add half the salsa to pan. Spray your baking pan with non-stick spray (or lightly oil). Then add half the picante sauce to your pan.
4. Top with tortillas and veggies. Next, add a layer of tortillas (breaking them to fit the pan, as needed) and half the bean-veggie filling.
5. Add more tortillas and ricotta. Layer more tortillas over the veggies, then top with all of the ricotta.
6. Repeat veggie layer. Top the ricotta with another layer of tortillas, then add the remaining bean - veggie mixture. Finish by adding more tortillas and the remainder of the picante sauce.
7. Bake. Cover the pan with foil, then bake until hot. Remove the foil, then top with shredded cheese. Continue baking until the cheese is melted and lightly browned.

When your Mexican Veggie Lasagna is done baking, let it rest for five to 10 minutes. This will help everything hold together when you slice it.

Topping Ideas

Serve this delicious casserole as-is or with your favorite toppings. I topped mine with chopped cilantro, sliced greens, and black olives, but avocado chunks, sour cream, salsa, fresh tomatoes, sliced jalapeños, and other Tex Mex-style toppings would also be delish!

Make Ahead Tips

If you are serving this dish for a party or on a busy week night, you can prepare and assemble everything ahead of time, cover, and refrigerate.

When you're ready to cook it, follow the baking directions. Just be aware that because you're starting with a cold casserole, you will probably need to add about 15 to 20 minutes extra cooking time.

Variations

You can easily customize this recipe by using different vegetables (try adding spinach, sweet and spicy peppers, mushrooms, and different kinds of squash). Other beans, such as pintos, will also work.

As far as tortillas go, flour ones will work. I personally prefer the texture of the corn tortillas though. You could also use crushed tortilla chips in a pinch.

Serving Suggestions

This Veggie Taco Lasagna makes a great one dish meal! If you'd like to round out your weeknight dinner, try serving it with a simple Green Salad.

If you're entertaining, your guests will enjoy it paired with other Tex Mex faves, like Black Bean and Corn Salsa, Mexican Spinach Dip, Black Bean Taquitos, or Bell Pepper Nachos.

Storage

Leftovers will keep for three to four days when stored in an airtight container in your refrigerator. You may also freeze leftovers for one to two months. To reheat, gently warm in your microwave.
