Idaho Potato and Pork Tamale Casserole with Green Salsa
A hearty Mexican-inspired casserole that transforms traditional tamales into an easy-to-serve family dish. Tender pork sirloin and cubed Idaho potatoes are layered with masa harina dough and wrapped in banana leaves for authentic flavor. The homemade tomatillo salsa adds bright, tangy notes that balance the rich pork and earthy masa. Perfect for Sunday dinners or special occasions when you want tamale flavors without the individual wrapping process. The banana leaf lining infuses the casserole with subtle herbal aromatics while keeping the masa moist during baking.

Tips
Pass banana leaves over an open flame briefly to make them pliable and prevent tearing when folding over the casserole layers.
Reserve both the pork and vegetable cooking waters as they add essential flavor to the masa dough and green salsa.
Test masa consistency by checking if it releases cleanly from your hands - add reserved cooking liquid gradually if too dry.
Good to Know
Refrigerate covered for up to 3 days. Reheat individual portions in microwave or oven until heated through.
Assemble casserole up to 1 day ahead and refrigerate before baking. Add 10-15 minutes to baking time if baking from cold.
Serve warm topped with red salsa and additional cilantro. Cut into wedges like a pie for easy portioning.
Common Mistakes
Don't skip flaming the banana leaves to avoid tearing during assembly.
Keep masa dough slightly moist to prevent cracking during baking.
Reserve cooking liquids to maintain authentic flavors in masa and salsa.
