Fill your largest pot with water. Boil until just al dente. Better to under cook than over cook as it will cook again baked in the oven. Drain the pasta.
Lay your pasta in a 12" casserole. Melt four tablespoons butter, pour over the pasta and mix in with your hands. Next beat the 2 eggs and pour that over the pasta as well. Add the parmesan, nutmeg, salt and pepper into the pasta, mix with your hands and set aside while you make the meat sauce.
Meat Sauce
Brown the ground beef, onions and garlic. Then add the rest of the ingredients and let cook for 30 minutes.
Pour the meat sauce onto the pasta and gently mix in. Preheat your galley oven to 350 degrees and clean out your large pot, as you will be using it again.
Béchamel
In a large sauce pan melt the butter, add the flour and cook for 2 minutes. Add the milk and cook, stirring constantly until the sauce thickens. Add the nutmeg, salt and pepper. Take off the burner and let cool down a bit so it’s no longer hot.
Once the sauce has cooled down whip in the 4 beaten eggs and blend into the sauce.
Baking the Pastitsio
Pour the sauce evenly over the top of the pasta.
Sprinkle with the last 1/4 cup parmesan and gate on some nutmeg if you’d like.
Place in your preheated oven. Cook for about one hour or until puffed up and golden brown on top. Let rest for 10 minutes or more until serving.
