Steps

Before you start

Preheat your oven to 375°F (190°C)
Gather all ingredients and have them measured and ready
If your tortillas are dry, lightly mist them with water to make them pliable

1
Brown the beef
- Heat a large 12-inch skillet over medium-high heat.
- Add the ground beef and cook, breaking it apart with a wooden spoon, until no pink remains and the meat is deeply browned, 8–10 minutes.
- The meat should form small, crumbly bits and reach an internal temperature of 160°F (71°C).
- Drain off excess fat if there is more than 2 tablespoons.

Ready when: No pink remains in the meat; internal temperature reaches 160°F (71°C); edges are deeply browned
Tip: Don't stir constantly—let the beef sit for 2–3 minutes between stirring so it browns instead of steaming.
2
Build the seasoning base
- Reduce heat to medium.
- Add the diced onion to the beef and cook, stirring, for 2 minutes until it just begins to soften.
- Stir in the minced garlic and cook for 1 minute until fragrant.
- Add the cumin, smoked paprika, salt, and black pepper.
- Stir constantly for about 30 seconds so the spices bloom in the hot oil.

Ready when: Spices are fragrant and coat the meat evenly
Tip: Don't skip blooming the spices—it deepens their flavor significantly.
3
Add salsa and beans
- Pour in the salsa and stir well to combine.
- Add the drained black beans and stir until everything is evenly mixed.
- Let this simmer for 2 minutes to let the flavors meld.
- The mixture should look like a chunky, saucy filling—not dry.

Ready when: Beans are heated through and ingredients are evenly combined
Tip: If the filling looks too thick, add 2–3 tablespoons water to keep it saucy for layering.
4
Prep the baking dish
- Remove the skillet from heat.
- Lightly coat a 9×13-inch baking dish with nonstick spray or a thin layer of oil.
- Spread about ½ cup (120 ml) of the beef mixture on the bottom of the dish—this prevents the tortillas from sticking.

Tip: A thin layer of filling underneath keeps the bottom tortillas from burning and sticking.
5
Layer tortillas and filling
- Arrange 4 corn tortillas in a single layer on the bottom of the dish, overlapping as needed to cover the surface.
- Spread one-third of the remaining beef mixture over the tortillas.
- Sprinkle one-third of the shredded cheddar cheese evenly over the beef.
- Repeat with two more layers: 4 tortillas, one-third of the beef, one-third of the cheese.
- Top with the final 4 tortillas and finish with the remaining cheese spread in an even layer.

Ready when: Three complete layers visible with cheese on top
Tip: Overlapping tortillas slightly ensures no gaps where filling can dry out. Don't press down hard—keep layers loose.
6
Bake until bubbly and goldenOven 375°F / 190°C
- Cover the baking dish loosely with foil and place in a preheated 375°F (190°C) oven.
- Bake for 20 minutes covered.
- Remove the foil and bake for another 12–15 minutes until the cheese on top is melted and lightly browned, and you can see filling bubbling at the edges of the dish.

Ready when: Cheese is melted and starting to brown; filling bubbles at the edges
Tip: Cover with foil for the first 20 minutes to trap moisture so tortillas don't dry out, then uncover to brown the cheese.
7
Rest and serve
- Remove the casserole from the oven and let it rest for 10 minutes.
- This allows the layers to set slightly so they don't fall apart when you serve.
- Cut into 6 portions and transfer to plates.
- Top with a dollop of sour cream, a sprinkle of cilantro, and sliced jalapeños if using.

Ready when: Casserole is set enough to cut cleanly
Tip: Resting is crucial—cutting into a hot casserole will cause it to fall apart.

Tips

For crispier tortilla edges, brush each tortilla lightly with a thin layer of oil before layering. This prevents them from drying out and encourages browning.
Don't skip the rest period after baking—it's not optional. The casserole will be easier to cut and much more pleasant to eat.
If you like more spice, add ½ teaspoon cayenne pepper with the other spices, or serve with hot sauce on the side.
Leftover casserole can be broken into pieces and folded into a warm flour tortilla with sour cream for a quick wrap the next day.

Make ahead

Assemble the casserole up to the end of Step 5 (before baking), cover tightly with foil, and refrigerate for up to 8 hours. Add 5–10 minutes to the covered baking time if baking straight from cold.

Storage & reheating

Store covered in the refrigerator for up to 3 days. Reheat covered with foil at 350°F (175°C) for 15–20 minutes until warmed through. Freezes well for up to 2 months: wrap tightly in foil and then plastic wrap after cooling. Thaw in the refrigerator overnight and reheat as above.

Substitutions

corn tortillas (6-inch / 15 cm) → flour tortillas. Flour tortillas create a softer, thicker casserole layer. Use the same quantity; they will absorb slightly more liquid.
sharp cheddar cheese → Mexican blend cheese or Oaxaca cheese. Mexican blend melts smoothly and adds authentic flavor. Oaxaca will be extra creamy. Use the same quantity.
red salsa → enchilada sauce (red or green). Enchilada sauce creates a thinner, saucier casserole with more depth. Use the same quantity and add 2–3 tablespoons water if it seems too thick.
canned black beans → pinto beans or refried beans. Pinto beans add earthiness. Refried beans make it creamier; use ¾ cup (180 ml) refried beans mixed with ¼ cup (60 ml) water.
