Instructions
Cook the Pasta
Pre-heat your oven to 350°F. Grease a 9×13-inch baking dish.
Boil the pasta in well-salted water (1 tbsp kosher salt) until just shy of al dente. Drain well.
Whisk 2 egg whites with a pinch of salt. Immediately toss the hot pasta with the egg whites to coat; set aside.
Make the Lamb Sauce
In a wide skillet, heat 2 tbsp olive oil over medium heat until just shimmering.
Add onion and cook 5–6 min until soft.
Stir in garlic for 30 seconds until fragrant.
Add the ground lamb and cook, breaking up, until no longer pink with some good browning.
Season the lamb with 1 tsp kosher salt, ½ tsp pepper, and 1 tsp ground cinnamon.
Stir in tomato paste; cook for 1 minute until a dark rusty color.
Add the crushed tomatoes, red wine, chicken broth, bay leaf, and cinnamon stick, scraping up any browned bits stuck to the bottom of the pan with a wooden spoon.
Simmer for 15–20 min until thickened and spoonable.
Remove the bay leaf and cinnamon stick; and taste before seasoning with more salt if needed.
Make the Béchamel
In a saucepan, melt 6 tbsp of butter over medium heat.
Whisk in ½ cup flour; cook for 2 minutes.
Gradually whisk in 4 cups of warm milk until smooth.
Simmer, continuously whisking, for 3 to 4 min until lightly thickened.
Remove the pan from the heat and whisk in ¾ tsp kosher salt and ¼ tsp nutmeg.
In a small bowl, whisk 2 egg yolks.
Slowly ladle in 1 cup of the hot sauce into the bowl while whisking the eggs to temper.
Then whisk yolk mixture back into the pot. Stir in ½ cup Parmesan cheese.
Assemble
Spread all of the egg-white–coated pasta in the prepared baking dish.
Spoon the lamb sauce evenly over the pasta.
Carefully, pour the béchamel over the top; tap the pan to level it all.
Bake & Serve
Bake for 35–40 minutes, until the top is set with light golden spots.
Rest for 15–20 minutes before slicing to give you the best square slices or serve sooner for a slightly more rustic, creamier slice.
Garnish with chopped parsley.
Notes
Shopping tip: Choose hollow pasta. Pastitsio works best with pasta that has a center hole (pastitsio noodles, ziti, penne, or bucatini).
Salt the pasta water well. This is the only chance to season the noodles themselves.
Drain the pasta completely before adding egg whites. Excess water prevents the pasta from binding, leading to a loose bottom layer. But work quickly, because if the pasta is cool, it won't have the same effect when tossing with the egg white.
Brown the lamb before adding liquids. If the pan looks watery, keep cooking. That’s moisture that's still releasing, not ready for the sauce yet.
Keep the meat sauce spoonable, not too thick.
Warm the milk for the béchamel. Cold milk increases the risk of lumps and uneven thickening. Let your milk sit at room temp or gently warm it before whisking it in for a velvety smooth sauce.
Béchamel should coat a spoon. If it’s too thick in the pot, it will dry as it bakes.
Tap the pan after assembling. This levels the béchamel and eliminates hidden air pockets.
Let the pastitsio rest before slicing. This is what makes or breaks your slice. You must rest it for 15-20 minutes.
Expect better leftovers. Pastitsio firms up overnight and slices even cleaner the next day. And let's not forget, the flavors deepen, so really this is a perfect make-ahead meal.
