Instructions
Heat the oven
Preheat to 425°F (220°C). Line two sheet pans with parchment for easy cleanup.
Prep the veggies
Toss sliced bell peppers, red onion, and zucchini with olive oil, garlic, chili powder, cumin, smoked paprika, oregano, salt, and pepper. Spread in a single layer on sheet pans.
Roast the veggies
Bake for 18–22 minutes, stirring once, until edges are caramelized and veggies are tender with some char. Reduce oven to 375°F (190°C).
Make the sauce
In a bowl, mix salsa and tomato sauce. Taste and adjust salt or spices. If you like heat, add a pinch of cayenne or minced jalapeño.
Prep the beans and corn
In a separate bowl, combine black beans and corn. Season with a pinch of salt, pepper, and a squeeze of lime.
Assemble the first layer
Spread a thin layer of the salsa mixture on the bottom of a 9×13-inch baking dish. Add a layer of tortillas, overlapping as needed to cover the surface.
Add fillings
Spoon a third of the roasted veggies over the tortillas. Add a third of the bean-corn mix. Drizzle with sauce and sprinkle with cheese.
Repeat layers
Continue layering tortillas, veggies, beans, sauce, and cheese for a total of three layers. Finish with a generous layer of cheese on top.
Bake
Cover loosely with foil (tent it so it doesn’t stick to the cheese) and bake at 375°F for 20 minutes. Remove foil and bake another 10–12 minutes, until bubbly and golden.
Rest and finish
Let sit for 10–15 minutes so it sets. Sprinkle with chopped cilantro and a squeeze of lime before slicing.
Serve
Cut into squares. Add a dollop of sour cream or Greek yogurt, avocado slices, and extra salsa if you like.
How to Store your mexican lasagna
- Refrigerate Cool completely, then cover tightly in an airtight container. Store for up to 4 days.
- Freeze Wrap the whole dish (or individual portions) in foil and freeze up to 2 months. For best texture, freeze before baking; thaw overnight and bake as directed.
- Reheat Oven at 350°F for 15–20 minutes, covered. Microwave single portions for 1–2 minutes, then let rest so heat distributes.

What Not to Do
❌ Don’t skip roasting the veggies Raw vegetables release water and make the Mexican lasagna soggy. Roasting concentrates flavor and keeps texture firm.
❌ Don’t drown it in sauce You want moist, not soupy. Use enough to coat each layer lightly.
❌ Don’t cut it too soon Resting your Mexican lasagna helps the layers set so slices hold together.
❌ Don’t forget to taste as you go: Season the beans and sauce. Balanced seasoning is key.
❌ Don’t use stale tortillas They’ll crack and dry out. Fresh tortillas make better layers.
Recipe Variations
✅ Spicy verde Use salsa verde (green salsa) and pepper jack cheese. Add poblano peppers to the roast mix.
✅ Sweet potato boost Roast cubed sweet potato with the veggies for a heartier, slightly sweet bite.
✅ Mushroom umami: Add roasted mushrooms for a savory, meaty texture.
✅ Dairy-light: Use less cheese and add a layer of mashed seasoned black beans to keep it creamy.
✅ Gluten-free: Choose certified gluten-free corn tortillas and check labels on salsa and spices.
✅ Vegan Swap the cheese for a good melting plant-based cheese or use a cashew cream drizzle between layers.
✅ Breakfast twist Add softly scrambled eggs or tofu scramble to one layer for brunch.

Notes
FAQ: Mexican Lasagna Recipe
Can I make this ahead?
Yes. Assemble the lasagna, cover, and refrigerate for up to 24 hours before baking. Add 5–10 minutes to the bake time if it’s cold from the fridge.
Corn or flour tortillas—what’s best?
Both work. Corn tortillas add authentic flavor and a slightly firmer bite, while flour tortillas create softer, more pasta-like layers. Use what you prefer.
How do I prevent soggy layers?
Roast the vegetables, don’t over-sauce, and let the lasagna rest before cutting. If using very watery salsa, simmer it for a few minutes to reduce.
Can I use refried beans?
Absolutely. Spread a thin layer of refried beans on the tortillas or dollop between layers. It adds creaminess and helps everything stick together.
What cheese melts best?
Monterey Jack and Oaxaca melt beautifully. A Mexican blend is convenient and tasty. For extra flavor, mix in a bit of sharp cheddar.
Is this kid-friendly?
Yes. Use mild salsa and skip jalapeños. Serve with avocado and a little sour cream to mellow the spices.
