3/4 cup parmagiano-reggiano cheese – finely grated
1 lb dry flat lasagna noodles
8 oz fresh mozzarella cheese – thinly sliced
Instructions
Make the bechamel sauce and set aside
Heat 2 TBL olive oil in a large heavy bottom pot on medium 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 8-9 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 low boil and reduce by half, then drop in the bay leaves, add the milk and reduce the heat to a low simmer and cook for 1-1/2 to 2 hours, scraping fat or foam off the top
Add water, chicken, or veal stock to thin if necessary. 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 while it simmers
Remove from heat, set aside to cool slightly and skim fat off the top with a ladle and discard
Preheat your oven to 350 and coat the inside of a 9″ x 13″ baking dish with the remaining olive oil
Build the lasagna beginning with a layer of bechamel, a sprinkle of shredded cheese, then a layer of noodles, and lightly cover with bolognese sauce
Repeat the process until the pan is full and bolognese is the last layer, then 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, reheating before serving
