Mexican Lasagna

If you’re looking for Mexican lasagna, this is seasoned ground beef with fire-roasted tomatoes, green chiles, and black beans layered with corn tortillas and a pile of jack-and-cheddar, three times, in a 9×13. 350°F covered 30–40 minutes, rest 10 so it slices. Corn tortillas, not lasagna noodles. Don’t call it classic lasagna or slow cooker lasagna.

Ingredients 🛒

• 1 pound ground beef
• 1 medium yellow onion, diced
• 2 teaspoons minced garlic (2 cloves)
• ¼ cup taco seasoning (2 packets)
• ½ cup water
• 1 (14.5-ounce) can fire-roasted diced tomatoes, undrained
• 1 (4-ounce) can green chiles
• 1 (15-ounce) can black beans, drained and rinsed
• 18 corn tortillas, divided
• 6 cups shredded jack and cheddar blend, divided
• Diced tomato and sliced green onion, for garnish
• Sour cream, for serving

Corn tortillas, not flour. Flour turns gummy in this steam. 18 tortillas is 6 per layer. Overlap them; gaps are meat leaking through.

¼ cup taco seasoning is two packets on this dest. It’s salty. Don’t add extra salt until you taste. ½ cup water is for the seasoning, like taco meat — this is not crustless taco pie (that pie gets no extra water).

Fire-roasted tomatoes, undrained. Drain them and the tortillas stay stiff. Regular diced tomatoes work; you’ll miss the char.

6 cups cheese sounds like a lot, then you do three layers. Shred a block. Bagged shreds can stay powdery.

Beef to no pink. This isn’t a raw-meat lasagna.

Equipment

A 9×13, sprayed. A skillet. Foil. 350°F. A 8×8 with this amount overflows — half batch or a bigger pan.

How to Make It 👩‍🍳

Heat oven to 350°F. Spray the 9×13.

Beef and onion, medium, until the meat is browned and the onion is soft. Drain grease. Garlic 1–2 minutes. Taco seasoning and ½ cup water, stir. Tomatoes with juice, green chiles, rinsed beans. Heat through.

6 tortillas on the bottom, overlapped. ⅓ of the meat. 2 cups cheese. Repeat twice: tortillas, meat, cheese. You should end on cheese.

Foil. Bake 30–40 minutes until bubbly and the cheese is melted. Rest 10 minutes. Garnish tomato and green onion. Sour cream at the table.

Why the Technique Works

Corn tortillas need steam from covered, wet filling. Uncovered the whole time dries the edges into chips while the middle is still a cold brick.

Three layers, 6 tortillas each is dest architecture. Two layers is a dip. Four is a dry stack unless you add filling.

Rest 10 minutes is how you cut squares. Same logic as Italian lasagna, different noodles.

¼ cup seasoning + undrained tomatoes is salt and liquid. Taste the meat before you commit extra salt. Cheese still goes on.

Cooking Tips

Rinse the beans. Don’t rinse the tomatoes.

If tortillas crack when you overlap, they’re stale. Microwave under a damp towel 20 seconds.

Variations and Substitutions

Ground turkey: drier. Don’t skip the tomato juice.

No beans: extra meat or skip. Don’t replace with a can of refried unless you want paste.

Flour tortillas: not this bake. They glue.

Serving Suggestions

Sour cream, extra tomato, green onion. A salad. Leftovers are lunch, not automatic nachos.

Storage, Freezing & Reheating

Fridge 4 days. Reheat 325°F covered.

Freeze up to 2 months. Thaw in the fridge. Tortillas soften. Don’t freeze, thaw, refreeze.

Troubleshooting

Soggy: extra water, or you used flour tortillas. Dest water is ½ cup in the meat, not a cup in the pan.

Dry/stiff tortillas: not enough tomato juice, or no foil. Cover, undrained tomatoes.

Salty: two packets plus cheese plus canned tomatoes. Low-sodium beans, taste the meat, maybe 1 packet next time if your brand is aggressive.

Won’t slice: no rest. 10 minutes.

Greasy: didn’t drain beef.

FAQ

Corn or flour?

Corn. Flour is a different, gummier pan.

Is this classic lasagna?

No. Different noodles, different sauce, different URL.

Do I cook the tortillas?

No. They steam in the filling under foil.

Two packets of taco seasoning?

That’s dest ¼ cup. If your packets are huge and salty, start with one, taste.
