I make this Mexican lasagna layered casserole on repeat when I need something filling, family-friendly, and impossible to mess up. It’s like lasagna’s bold cousin: layers of seasoned beef, black beans, fire-roasted tomatoes, corn tortillas and melty cheese baked until bubbly. It’s fast enough for a weeknight, portable for potlucks, and—best of all—everyone gets seconds.
Why you’ll love this dish
This casserole hits a lot of home-cooking sweet spots: it’s budget-friendly, feeds a crowd, and uses pantry staples you probably already have. The corn tortillas act like pasta sheets but give the dish a pleasant corn flavor and a lighter texture. Quick browning on the stovetop plus a short bake time means dinner on the table without marathon prep.
- Weeknight winner: ready in under an hour.
- Kid-approved and easy to customize.
- Feeds 6–8 depending on sides and appetite.
- Uses one pan for the filling and one baking dish—minimal cleanup.
“I doubled the beans and added sliced jalapeños—my whole family went back for thirds. Perfect weeknight comfort food.” — a happy home cook

What you’ll need
- 1 lb ground beef (85/15 is a good balance; you can use ground turkey or plant-based crumble as a swap)
- 1 yellow onion, diced
- 1 can black beans, rinsed and drained (or use pinto beans)
- 1 can fire-roasted tomatoes (14–15 oz)
- 8 corn tortillas (soft, room temperature—warmed briefly helps them bend)
- 3 cups shredded cheese (cheddar or Mexican blend; Monterey Jack melts well)
- 2 teaspoons taco seasoning (store-bought or homemade)
- Salt and pepper to taste
- Optional toppings: sour cream, avocado, cilantro, sliced jalapeño, lime wedges
Substitutions/notes: swap corn tortillas for flour if you prefer a softer layer (flour will be softer/more breadlike). For a vegetarian version, double the beans and add sautéed mushrooms and bell peppers.
Directions to follow
- Preheat the oven to 375°F (190°C).
- Heat a large skillet over medium. Add the ground beef and diced onion. Break the meat up and cook until the beef is browned and the onion is translucent, about 6–8 minutes. Drain excess fat if the beef is very greasy.
- Stir in the rinsed black beans, fire-roasted tomatoes (undrained), and taco seasoning. Season with salt and pepper. Let the mixture simmer for about 5 minutes so the flavors marry and some liquid reduces. Taste and adjust seasoning.
- Spread a thin layer of the beef mixture across the bottom of a 9×13-inch baking dish. Arrange a layer of corn tortillas on top—you can overlap pieces to cover gaps. Sprinkle about a third of the cheese over the tortillas.
- Repeat: beef mixture, tortillas, cheese, until ingredients are used. Finish with a generous layer of cheese on top.
- Cover the dish tightly with foil and bake for 25 minutes. Remove the foil and bake an additional 15 minutes, or until the cheese is bubbly and golden.
- Let the casserole rest for 5–10 minutes before slicing—this helps it set so portions hold together. Serve with sour cream, diced avocado, chopped cilantro, and lime wedges if desired.
Best ways to enjoy it
- Serve with a crisp green salad or a simple cabbage slaw for crunch and brightness.
- Add a side of Mexican rice or cilantro-lime quinoa to make it a full meal.
- For a lighter plate, top individual slices with lettuce, pico de gallo, and a dollop of Greek yogurt or sour cream.
- Make it a potluck star: bake in a disposable pan and bring toppings separately so they stay fresh.
Storage and reheating tips
- Refrigerator: Store leftovers in an airtight container for 3–4 days. Cool to room temperature (no more than 2 hours out), then refrigerate.
- Freezer: Wrap tightly or transfer portions to freezer-safe containers and freeze up to 3 months. Thaw overnight in the fridge before reheating.
- Reheat: Oven method gives best texture—cover and bake at 350°F (175°C) until heated through, about 15–20 minutes for a whole dish or 10–12 minutes for individual portions. Microwave for 1–2 minutes for single servings, stirring or covering to retain moisture. Reheat to an internal temperature of 165°F (74°C) for safety.
- Safety note: Refrigerate leftovers promptly and reheat only once.
Helpful cooking tips
- Warm tortillas briefly in a dry skillet or wrapped in a damp towel in the microwave for 20–30 seconds—they’ll bend without cracking.
- Drain excess fat from browned beef to prevent a soggy casserole. If using leaner meat, you can skip draining.
- Don’t over-layer—three tiers (filling/tortillas/cheese repeated) works best with these quantities. Too many layers can make slices fall apart.
- If you like a slightly crispy edge, remove foil for the last 10–15 minutes and move the dish to the top rack for a few minutes to brown. Watch closely to avoid burning.
- Make it ahead: assemble the casserole, cover it, and refrigerate for up to 24 hours before baking—add 5–10 extra minutes to the covered bake time.
Creative twists
- Vegetarian: Replace beef with sautéed mushrooms, zucchini, and extra black beans or crumbled firm tofu seasoned with smoked paprika.
- Chicken version: Use shredded rotisserie chicken mixed with taco seasoning and a bit of enchilada sauce.
- Spicy kick: Stir in chopped pickled jalapeños or a can of green chiles. Add cayenne or chipotle in adobo for smokiness.
- Cheesy variations: Swap part of the cheddar for pepper jack for heat, or top with queso fresco after baking for a fresher finish.
- Low-carb: Use thinly sliced eggplant or roasted zucchini rounds in place of tortillas.
Common questions
Q: Can I make this ahead of time?
A: Yes—assemble the casserole, cover tightly, and refrigerate for up to 24 hours. Add about 5–10 extra minutes to the covered baking time since it will start cold.
Q: Will corn tortillas make it soggy?
A: If tortillas are too wet or the filling is very saucy, it can be softer. Warm tortillas before layering to make them pliable and drain excess liquid from the filling. Slightly under-cooking the filling liquid on the stovetop helps too.
Q: Can I freeze the baked casserole?
A: Yes. Cool completely, wrap well or transfer to freezer-safe containers, and freeze up to 3 months. Thaw in the refrigerator overnight and reheat in the oven until heated through.
Q: Is there a recommended cheese?
A: A Mexican-blend or a mix of cheddar and Monterey Jack melts well and gives good flavor. Pepper jack adds heat if you like spice.
Q: How do I keep portions from falling apart?
A: Let the casserole rest 5–10 minutes after baking so it firms up. Using slightly overlapping tortillas and not over-layering helps slices hold together.
