Pastitsio is a quintessential Greek comfort dish featuring al dente penne pasta layered with a rich, aromatic ground lamb and tomato sauce, subtly spiced with cinnamon. It's generously topped with a velvety, smooth béchamel sauce and baked until golden brown. This hearty casserole makes for a satisfying and flavorful main course.
Achieving a truly authentic Pastitsio hinges on a few key elements. When browning the lamb, ensure excellent caramelization to build a deep flavor base, then thoroughly drain excess fat. The red wine deglazing adds crucial acidity and depth; reduce it completely. For the béchamel, cook the roux for at least a minute to eliminate any raw flour taste before gradually whisking in warm milk to prevent lumps. A pinch of nutmeg in the béchamel enhances its classic flavor. Al dente pasta is essential as it will continue cooking in the oven. Allow the baked Pastitsio to rest for 15-20 minutes after removing from the oven; this sets the layers, making for cleaner slices and a better presentation.
