Recipe Tips
For optimal flavor development, consider assembling this casserole up to 24 hours in advance and refrigerating before baking. The resting time allows the seasonings to fully permeate all the ingredients. If baking from refrigerated, add 5-10 minutes to the baking time. The tortillas can be warmed in batches to make the process quicker. Be sure to handle them gently to prevent tearing.
