3/4 cup parmagiano-reggiano cheese – finely grated
1 lb dry flat lasagna noodles
6–8 oz fresh mozzarella cheese – thinly sliced
Instructions
Make the bechamel sauce
Heat 2 TBL olive oil in a large heavy bottom pot on medium-high heat
Add the onion, carrot, celery, garlic and thyme and season with salt and pepper
Cook while stirring with a spatula until everything is tender and has released their juices, about 7-9 minutes
Stir in the livers and cook on high heat for 2 minutes, then add the beef, veal and pork
Stir and break up the meats on medium heat until all the meat is browned, stirring regularly and scraping the bottom to prevent scorching.
Add the tomato paste, stir and cook about 20 minutes
Add the wine, bring to a boil and reduce by half
Drop in the bay leaves, add the milk and return to a boil
Reduce the heat to a low simmer and cook for 1-1/2 to 2 hours.
Add water or chicken stock or veal stock to thin as “necessary”
Note: AB does not describe what necessary is. My experience is there needs to be enough liquid to allow for scraping the fat off the top per the last instruction, but it should not be soupy.
Taste and adjust seasoning with salt and pepper several times while simmering
Remove from heat, set aside to cool slightly and skim fat off the top with a ladle and discard
Preheat your oven to 350
Coat the inside of a 9″ x 13″ baking dish with the remaining olive oil
Build the lasagna by beginning with a layer of bechamel, a sprinkle of shredded cheese, then noodles, and then bolognese sauce
Repeat the process until the pan is full and bolognese is the last top layer
Cover the bolognese with a layer of the thinly sliced mozzarella
Place the baking dish on a baking sheet in the center of the oven and bake for about 50 minutes or until the mozarella is browning and the lasagna bubbling
Remove and rest for a minimum of 15-20 minutes before slicing, but it gets better resting overnight to give the flavors time to meld
