A simple Mexican spin on lasagna.
Enchilada sauce does the primary structural and chemical work in this dish, acting simultaneously as a braising liquid for the tortillas and a flavor binder for the starch and dairy. Because tortillas absorb moisture aggressively when enclosed in a baking environment, managing the volume of sauce per layer determines whether the final result holds together cleanly or slumps into a loose casserole. When building the dish, spread the sauce sparingly across each tortilla surface rather than pooling it, ensuring the starch softens without dissolving into paste.
Achieving structural integrity in layered tortilla dishes requires balancing the high moisture content of refried beans against the dry heat of a standard 350 degree Fahrenheit oven. Refried beans contain varying amounts of residual water depending on whether they are canned or scratch-made, and excess moisture will steam the surrounding starches rather than baking them. Constructing stacks with tight contact between the cheese and the tortillas prevents the edges from curling upward and drying into sharp, unpalatable shards during the twenty to thirty minute cooking window. Although bake times serve as a baseline, visual cues remain the most reliable indicator of completion. Watch for the cheese across the top surface to turn completely molten, bubbling actively at the edges, and showing light golden brown spotting where proteins have begun to caramelize.
