This Mexican lasagna combines the comfort of a baked casserole with the bold, familiar flavors of a taco night. The beef is seasoned with taco spices, while tomatoes with green chiles and red enchilada sauce create a rich, lightly smoky filling that coats every tortilla.
It is also an efficient recipe for busy evenings. The filling cooks in one skillet, the tortillas need only a quick warming, and the entire dish bakes in a single square pan.
The finished casserole is substantial without requiring a long ingredient list. Black beans add texture and heartiness, and the cheese melts into the sauce to create soft, savory layers that hold together after a short rest.

Ingredients You’ll Need
The ingredient list is built around pantry-friendly staples, so this is an excellent recipe to make when you want a filling dinner without a special grocery trip. Use lean ground beef for a balanced filling and drain the skillet after browning.
- Ground beef and onion: These form the savory base of the casserole. Chopping the onion fairly small helps it soften at the same time as the beef.
- Taco seasoning: One packet, about 1–1.25 ounces, brings salt, chile, cumin, garlic, and other classic taco flavors.
- Black beans: Rinse and drain the beans before adding them so the filling does not become watery or overly salty.
- Diced tomatoes: Use a 14–15 ounce can, preferably with green chiles, and keep the liquid because it helps loosen the sauce.
- Red enchilada sauce: A 10-ounce can adds moisture and a deep chile flavor to the meat mixture.
- Corn tortillas: Nine small tortillas, about 6 inches each, create three layers in an 8-inch or 9-inch square baking dish.
- Mexican-blend cheese: Two cups, or 8 ounces, provide a generous melted topping and help bind the layers.
For serving, set out sliced jalapeños, chopped cilantro, sour cream, avocado, or salsa. Each topping brings a different contrast: heat from jalapeños, freshness from cilantro, cool creaminess from sour cream or avocado, and a bright finish from salsa.
How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C), then lightly grease an 8-inch or 9-inch square baking dish. Greasing the dish makes serving easier and reduces the chance of browned sauce sticking to the corners.
Step 2: Place a large skillet over medium heat and add the ground beef and chopped onion. Cook for about 6–8 minutes, stirring and breaking the beef into small pieces, until the meat is browned and the onion has softened; drain excess fat.
Step 3: Add the taco seasoning, rinsed black beans, undrained diced tomatoes, and red enchilada sauce to the skillet. Stir until everything is evenly combined, then simmer for 3–5 minutes so the filling becomes hot and slightly thickened.
Step 4: Warm the corn tortillas before assembling the casserole. You can heat them briefly in a dry skillet or place them under a damp paper towel in the microwave; this small step makes them flexible and helps prevent cracks.
Step 5: Arrange 3 tortillas across the bottom of the greased baking dish, overlapping them where necessary. Spoon about one-third of the beef mixture over the tortillas and spread it close to the edges, then add about one-third of the shredded cheese.
Step 6: Repeat the layers two more times, using 3 tortillas, one-third of the beef mixture, and one-third of the cheese for each round. Make sure the last layer ends with cheese so the top becomes bubbling and lightly browned in the oven.
Step 7: Cover the dish loosely with foil and bake for about 20 minutes. The foil protects the cheese while the center heats through, but it should not be pressed tightly against the topping.
Step 8: Remove the foil and continue baking for 10–15 minutes, until the sauce is bubbling around the edges and the cheese has developed light golden spots. Watch closely during the final minutes because ovens and baking dishes can vary.
Step 9: Take the casserole from the oven and let it rest for 5–10 minutes before slicing. Finish each serving with your preferred toppings and serve while the cheese and sauce are still warm.
Pro Tips for Perfect Layers
Corn tortillas can tear when they are cold and stiff, especially when you try to fit them into the corners of a square dish. Warming them briefly makes them easier to overlap and gives the casserole a more even texture.
Do not drain the diced tomatoes, because their liquid works with the enchilada sauce to keep the tortillas tender. At the same time, do drain the browned beef and rinse the black beans so the filling has a thick, spoonable consistency rather than excess grease or water.
Spread the filling evenly over each tortilla layer. Reaching the edges helps every serving contain sauce, beef, beans, and cheese instead of leaving dry tortilla corners.
Keep the foil loose during the first part of baking. This allows steam to circulate without trapping the foil against the cheese, and removing it for the final 10–15 minutes gives the topping a pleasant golden finish.
The resting period is not optional if you want neat slices. Five to ten minutes gives the sauce time to settle and the cheese time to help the layers hold their shape.
Serving Suggestions
Serve this casserole as the centerpiece of a relaxed family meal. A crisp green salad, simple roasted vegetables, or a spoonful of rice can balance the rich beef and cheese without competing with the Tex-Mex flavors.
For a fresh topping bar, arrange cilantro, jalapeños, avocado, sour cream, and salsa in small bowls. Guests can customize each slice, making the dish suitable for both mild and spicy preferences.
If you want a complete menu with a sweet finish, keep a batch of easy cake balls ready for dessert. Their small size makes them convenient after a hearty casserole.
Storage and Reheating
Cool leftover casserole promptly, cover it, and refrigerate it. Stored portions are convenient for lunch or a second dinner, and the flavors often taste even more blended the next day.
For the best texture, reheat individual servings until hot throughout. A microwave works well for speed, while a covered oven-safe dish can warm several portions more gently; uncover briefly at the end if you want the cheese to regain some of its baked texture.
Keep toppings such as avocado, sour cream, cilantro, and salsa separate until serving. This preserves their freshness and prevents the casserole from becoming watery during storage.
