How to Make Beef Enchilada Casserole

Step 1 - Brown the beef and build the filling: Heat a large skillet over medium-high heat and add the ground beef. Spread it across the pan and let it sit without stirring for 2 full minutes so a crust forms on the bottom before you break it apart. Once browned, push the meat to the edges, add the diced onion to the center, and cook until softened, about 3 minutes. Add the garlic, cumin, chili powder, and smoked paprika and stir everything together, letting the spices cook in the beef fat for 60 seconds until fragrant. Stir in the drained black beans and season with salt. Add half a cup of the enchilada sauce directly to the beef mixture and stir to combine — this step keeps the filling moist during baking and prevents it from drying out in the oven.

Step 2 - Warm the tortillas in the sauce: Pour the remaining enchilada sauce into a shallow skillet or saucepan and warm it over low heat. Pass each corn tortilla through the warm sauce, letting it soak for about 10 seconds per side, and stack the sauce-coated tortillas on a plate. This brief contact with warm sauce makes the tortillas pliable enough to layer without cracking and infuses them with the smoky, chile flavor of the sauce from the inside out rather than leaving them as bland structural filler.

Step 3 - Layer the casserole: Spread a thin layer of enchilada sauce across the bottom of a 9x13 baking dish to prevent sticking and give the bottom tortillas something to absorb. Lay a single layer of sauce-coated tortillas over the base, cutting them as needed to fill the gaps. Spread half of the beef mixture evenly over the tortillas, then scatter one-third of the shredded cheese over the beef. Repeat the layers — tortillas, remaining beef, another third of the cheese — and finish with a final layer of tortillas followed by the last of the enchilada sauce poured evenly over the top.

Step 4 - Add the cheese and bake: Scatter the remaining shredded cheese in an even layer over the top of the casserole, covering all the sauce so the cheese can brown and blister rather than drying out as an exposed layer. Bake in a preheated 375 degree Fahrenheit oven, uncovered, for 25 to 30 minutes until the sauce is bubbling at the edges and the cheese on top is deeply golden with some browned spots. The bubbling edges tell you the internal temperature is high enough for the layers to have melded and the tortillas to have fully softened.

Step 5 - Rest and serve: Remove the casserole from the oven and let it rest uncovered for 8 to 10 minutes. Slice it into portions with a sharp knife or spatula and serve with sour cream, fresh cilantro, and sliced jalapeño on top. The garnishes are not optional decoration here — the cool, tangy sour cream contrasts the heat of the filling, the cilantro adds a fresh herbal note that cuts through the richness of the cheese, and the jalapeño gives the dish the same finishing punch a traditional enchilada plate would have.
