Mexican Lasagna is a layered casserole with seasoned ground beef, black beans, corn, tomatoes, and melted cheese baked between corn tortillas. It's an easy, family-friendly dinner that's ready in under an hour.
2 1/2cups shredded cheddar cheesefreshly grated off the block
Sour creamfor garnish
Sliced green onionfor garnish
Instructions
Preheat oven to 350 degrees F.
Heat a large skillet over medium heat. Add ground beef and cook until browned and no longer pink, breaking it into small crumbles as it cooks. Do not drain.
Stir in taco seasoning until the beef is evenly coated. Add drained corn, drained tomatoes, drained black beans, and 1/4 cup salsa. Stir to combine and set aside.
Spread 2 tablespoons of salsa across the bottom of a 9x13 inch baking dish.
Arrange 5 corn tortillas over the salsa (4 whole and 1 cut in half to fill gaps). Spread half the beef mixture over the tortillas and sprinkle with 1 cup of cheese.
Repeat with 5 more tortillas, the remaining beef mixture, and 1 cup of cheese.
Top with a final layer of 5 tortillas. Spread the remaining 2 tablespoons of salsa over the tortillas and sprinkle with the remaining 1/2 cup of cheese.
Bake uncovered for 30 minutes, or until the cheese is melted and the edges are bubbling.
Let rest for 10 minutes before slicing. This helps the layers set so slices hold together. Cut into 6-8 pieces and serve topped with sour cream and sliced green onions.
Notes
Cooking Tips:
Drain all canned ingredients well. Excess liquid is the #1 cause of a watery casserole. Press corn, beans, and tomatoes with paper towels if needed.
Don't drain the beef. The rendered fat keeps the filling moist, and the tortillas and beans absorb it as the casserole bakes.
Freshly shredded cheese off the block melts much better than pre-shredded, which is coated in anti-caking agents.
Let it rest a full 10 minutes after baking so the layers set up and slices hold together.
Substitutions:
Corn tortillas hold their shape best, but flour tortillas work if you prefer a softer texture.
Use mild salsa for a kid-friendly version, or go with medium/hot and add diced jalapeños for more heat.
Ground turkey, shredded chicken (rotisserie works great), or double the beans for a meatless version.
Pinto beans or refried beans work well in place of black beans.
Storage & Make-Ahead:
Make ahead: Assemble and refrigerate up to 24 hours before baking. Let it sit out while the oven preheats.
Freezing: Assemble unbaked, wrap tightly with plastic wrap and foil, and freeze for up to 3 months. Thaw overnight in the fridge before baking.
Leftovers: Refrigerate in an airtight container for 3-4 days. Reheat slices in the microwave, or cover a full pan with foil and bake at 350°F until warmed through.
