I made this up one night, and we love it!
Crisp corn tortilla fragments yield structurally under a blanket of bubbling, melted cheddar cheese, sealing in a savory stratum of spiced beef, sweet kernels of corn, and acidic tomatoes. Casserole formats adapted from Tex-Mex bar snacks emerged as home cooks sought efficient ways to feed crowds without standing over individual plates of sheet-pan nachos. Transforming layered snacks into a cohesive baked dinner requires balancing moisture levels so the base components soften appropriately while retaining distinct textures.
Freezing this assembled unbaked casserole is not recommended because the high moisture content in the canned tomatoes and thawed vegetables will cause the tortilla chips to disintegrate into a mushy texture upon reheating. Utilizing a ceramic baking dish helps retain thermal stability during the 15-minute bake time, ensuring the interior ingredients reach serving temperature simultaneously.
