Ingredients

500g ground beef (or ground chicken/turkey)
1 small onion, finely chopped
3 cloves garlic, minced
1 cup canned black beans, drained and rinsed
1 cup corn kernels (fresh, frozen, or canned)
2 cups salsa (mild or spicy based on preference)
1 cup tomato sauce
1 teaspoon chili powder
1 teaspoon cumin
½ teaspoon smoked paprika
Salt and pepper to taste
6–8 medium flour or corn tortillas
2 cups shredded cheddar cheese
1 cup shredded mozzarella or Monterey Jack cheese
½ cup sour cream (optional, for topping)
Fresh cilantro, chopped (for garnish)
Sliced jalapeños (optional)

Instructions

Preheat the oven
Set your oven to 180°C (350°F) and lightly grease a medium-sized baking dish.
Cook the meat mixture
In a large skillet over medium heat, cook the ground beef until browned. Drain excess fat if needed.
Add aromatics
Stir in chopped onion and cook for 3–4 minutes until softened. Add garlic and cook for another minute until fragrant.
Build the flavor
Add salsa, tomato sauce, black beans, corn, chili powder, cumin, paprika, salt, and pepper. Mix well and simmer for 5–7 minutes until slightly thickened.
Start layering
Place a layer of tortillas at the bottom of the baking dish, trimming them if necessary to fit.
Add filling and cheese
Spread a portion of the meat mixture over the tortillas, then sprinkle a layer of shredded cheese.
Repeat layers
Continue layering tortillas, meat mixture, and cheese until all ingredients are used, finishing with a generous cheese layer on top.
Bake
Cover with foil and bake for 20 minutes. Remove foil and bake an additional 10–15 minutes until the cheese is melted and bubbly.
Rest before serving
Let the casserole rest for 5–10 minutes to set, making it easier to slice.
Garnish and serve
Top with sour cream, fresh cilantro, and jalapeños before serving.

Tips for Perfect Mexican Lasagna

1. Don’t skip resting time
Allowing the casserole to sit after baking helps the layers firm up, making it easier to cut clean slices.

2. Use quality salsa
Since salsa is a key ingredient, choose one with good flavor—it makes a big difference.

3. Balance moisture
Avoid overly watery fillings. If your mixture seems too thin, simmer a bit longer to reduce liquid.

4. Mix cheeses for best results
Combining cheddar with mozzarella or Monterey Jack creates the perfect melt and flavor balance.

5. Adjust spice level
Use mild salsa for a family-friendly dish or spicy salsa and extra jalapeños for more heat.

Delicious Variations

1. Chicken Mexican Lasagna
Swap ground beef for shredded rotisserie chicken for a lighter version.

2. Vegetarian Version
Replace meat with sautéed vegetables like zucchini, bell peppers, and mushrooms, or add extra beans.

3. Low-Carb Option
Use low-carb tortillas or thin slices of grilled zucchini instead of tortillas.

4. Creamy Tex-Mex Lasagna
Add a layer of cream cheese or a creamy sauce between layers for extra richness.

5. Spicy Kick Version
Include chipotle peppers in adobo sauce for a smoky heat upgrade.
