For the grand finale, I top everything with the final two torn tortillas. I pour the last of the sauce over the top, making sure to cover all the tortilla edges so they don’t dry out in the oven. Finally, I sprinkle the remaining cheese generously over everything. I cover the dish with foil and bake it in a preheated 350°F (175°C) oven for 25 minutes. Then, I remove the foil and bake for another 10-15 minutes, until the cheese is completely melted, bubbly, and just starting to get golden spots. The smell is incredible. I let it rest for 10 minutes before cutting—this is crucial for neat slices!
Pro Tips for Best Results
My number one tip is about the tortillas. I’ve tested this with corn tortillas, but for this creamy, casserole-style dish, flour tortillas are the winner. They soften perfectly and absorb the sauce without falling apart. To prevent a doughy texture, I tear them instead of cutting them cleanly. The ragged edges nestle together better and create more surface area for the sauce to soak into, giving you a better texture in every bite. Trust me, tearing is better than cutting here.
The second tip is all about balancing moisture. The cream soup in the sauce is your insurance policy against a dry casserole. If you’re out, you can substitute with an 8-oz block of softened cream cheese mixed into the enchilada sauce. Also, don’t skip that bottom layer of sauce. It steams the bottom tortilla layer, making it tender and flavorful instead of tough and chewy. If your assembled casserole looks a little dry before baking, don’t hesitate to open another small can of sauce or a little broth to drizzle over the top layer.
Finally, let it rest! I know it’s tempting to dive right in when it comes out of the oven bubbling like a cheesy volcano. But if you cut it immediately, the layers will slip and slide, and it will be a soupy mess on the plate. Letting it sit for a full 10 minutes allows the sauce to thicken slightly and the layers to set. This makes for picture-perfect, stackable squares that hold their shape.
Common Mistakes to Avoid
The first mistake I made was not draining the beef. I used 80/20 beef and skipped draining to keep the flavor. The result was a casserole swimming in orange grease—unappetizing and heavy. Always drain the cooked beef and onions well. You’ll keep all the flavor from the browning without the unpleasant grease pooling in your finished dish. (See the next page below to continue…)
