Mexican Lasagna Tex-Mex

The first time my cousin Maria brought this to a potluck, I swear I saw three people go back for fourths. It was one of those rainy Sundays where everyone shows up in sweatpants expecting chips and salsa, then ends up hovering around the baking dish like it's the most interesting thing in the room. Now it's the only thing my kids actually request by name, and I've caught my husband eating the leftovers cold for breakfast more than once.

I made this for my book club last winter when nobody could decide between Mexican night or comfort food, and the debate ended immediately. One friend actually admitted she'd been skeptical about lasagna without pasta, but she called me two days later demanding the recipe because her husband wouldn't stop talking about it.

Ingredients

• 500 g (1 lb) ground beef: I've learned that slightly higher fat beef keeps everything moist, but drain well after browning or it gets too heavy
• 1 medium onion, diced: Yellow onions work best here since they sweeten as they cook
• 2 cloves garlic, minced: Fresh garlic matters, but don't let it brown or it turns bitter
• 1 red bell pepper, diced: Adds this little pop of sweetness and color that makes the dish look beautiful when you slice it
• 1 can (400 g/14 oz) black beans, drained and rinsed: Rinse them really well or the sauce gets cloudy
• 1 can (150 g/5 oz) corn, drained: Sweet corn balances the spices perfectly
• 1 can (400 g/14 oz) diced tomatoes: Fire-roasted ones add this incredible depth if you can find them
• 1 packet (30 g/1 oz) taco seasoning: Make your own if you're watching sodium, but the packet works fine in a pinch
• 1/2 tsp chili powder: Optional, but I always add it because my family likes things with a little kick
• Salt and pepper: The taco seasoning has plenty, but taste at the end before adding more
• 8 medium flour tortillas: Corn tortillas get too soggy, and the flour ones soften into these amazing layers
• 300 g (3 cups) shredded Mexican cheese blend: Buy it pre-shredded or grate your own, but don't skip this amount
• Fresh cilantro, chopped: The bright, fresh herbiness on top cuts through all the rich cheese
• Sliced jalapeños: For anyone who wants to turn up the heat at the table
• Sour cream: A cool, creamy finish that ties everything together

Instructions

Get everything ready:

Preheat your oven to 180°C (350°F) and grease a 22x33 cm (9x13-inch) baking dish with a little oil or cooking spray.

Brown the beef:

In a large skillet over medium heat, cook the ground beef until it's no longer pink, breaking it up as it cooks. Drain off the excess fat so it doesn't get greasy.

Cook the aromatics:

Add the onion, garlic, and bell pepper to the skillet. Sauté for about 3 to 4 minutes until the vegetables soften and your kitchen starts smelling amazing.

Build the sauce:

Stir in the taco seasoning, chili powder if using, black beans, corn, and diced tomatoes. Let everything simmer together for 5 minutes, then season with salt and pepper to taste.

Start layering:

Place two tortillas in the bottom of your baking dish, tearing them as needed to cover the space completely. Spread one-third of the meat mixture over the tortillas, then sprinkle with one-fourth of the cheese.

Repeat the layers:

Do two more layers of tortillas, meat mixture, and cheese. Top with a final layer of tortillas and cover everything with the remaining cheese.

Bake covered:

Cover the dish loosely with foil and bake for 25 minutes. The foil keeps the tortillas from drying out while everything heats through.

Get it golden:

Remove the foil and bake for another 10 minutes until the cheese is bubbly and starting to turn golden in spots.

Let it rest:

Wait 5 minutes before slicing. This is crucial because it lets the layers set so you get nice clean pieces instead of a sloppy mess.

Finish it off:

Garnish with fresh cilantro, jalapeños, and sour cream if you want, but it's pretty fantastic on its own too.

Save

Last Thanksgiving, my usually traditional grandmother tried this and quietly admitted she liked it better than her classic lasagna. I didn't know whether to feel honored or terrified, but she's requested it for every family gathering since.

Make It Your Own

Ground turkey or chicken work beautifully if you want something lighter, and I've done a vegetarian version with extra beans, some roasted sweet potatoes, and plant-based crumble that surprised everyone who tried it. The beauty here is that the layering concept stays the same no matter what you swap in or out.

Serving Ideas

A crisp green salad with a lime vinaigrette cuts through all the cheese, and I've found that a light-bodied red wine or even an icy beer pairs surprisingly well. My niece insists on serving it with tortilla chips on the side for extra crunch, which isn't wrong even if I'd never thought of it myself.

Make Ahead Magic

You can assemble the entire thing up to a day ahead and keep it covered in the fridge, which actually helps the flavors meld together even more. Just add about 10 minutes to the baking time if it's coming straight from the refrigerator.

• Leftovers reheat surprisingly well in the microwave and taste even better the next day
• Freeze individual portions for those nights when nobody wants to cook
• The flavors actually get better as it sits, so don't be afraid to make it the morning before serving

Save

There's something about pulling this bubbling, golden dish out of the oven that makes people gather in the kitchen, forks in hand, like they're drawn by gravity. That's the best part of cooking, isn't it?

Recipe Questions & Answers

→ Can I make Mexican lasagna ahead of time?

Yes, assemble the entire casserole up to 24 hours in advance and refrigerate covered with foil. Bake when ready, adding 5-10 minutes to the covered baking time since it will be cold.

→ What tortillas work best for this dish?

Flour tortillas in medium size (8-inch) fold and layer easily without cracking. Corn tortillas can become brittle, though you can soften them by briefly warming before layering.

→ How do I store and reheat leftovers?

Refrigerate in an airtight container for up to 4 days. Reheat individual portions in the microwave for 2-3 minutes, or cover the entire dish with foil and warm at 180°C (350°F) for 15-20 minutes until heated through.

→ Can I freeze this casserole?

Absolutely. Wrap the unbaked or baked casserole tightly in plastic wrap and foil, then freeze for up to 3 months. Thaw overnight in the refrigerator before baking as directed, or bake from frozen adding 20-30 minutes to the time.

→ What cheese blend works best?

A Mexican cheese blend typically includes cheddar, Monterey Jack, asadero, and queso quesadilla. Shredded cheddar and Monterey Jack mixed together works perfectly if you prefer to shred your own.

→ How can I make this vegetarian?

Replace the ground beef with plant-based crumbles or simply add an extra can of black beans along with additional vegetables like diced zucchini or mushrooms. The seasonings and cheese provide plenty of savory flavor.
