Preparation

First make the Bolognese Sauce:
Brown and drain grease from the ground beef, ground pork and sausage in a large saute pan. Break up all lumps with spoon.
Add in 2 T butter and 1 T olive oil and saute the onions, garlic, carrots and celery until softened. Add salt and pepper to taste.
Add the wine and stir and then simmer for 5 minutes, or until reduced.
Add the tomatoes and 1 cup of beef stock and bring to a boil. Stir the sauce well, then lower heat and half cover pan with lid and simmer gently for 2 hours. Stir occasionally during this time and add more stock as it becomes absorbed.
Pour the cream into the sauce, stir well to mix, then simmer without lid for 30 minutes, stirring frequently.
AT THIS STAGE -- YOU CAN SERVE THIS OVER THICK PASTA. FOR LASAGNA BOLOGNESE -- CONTINUE WITH RECIPE.
Preheat oven to 375. If the bolognese sauce is cold, reheat it. Stir in enough stock to make it runny, if necessary.
Make the white sauce by melting 1/4 cup butter in a medium saucepan. Add the flour and cook, stirring for 1-2 minutes. Add the hot milk a little at a time, whisking vigorously after each addition. Bring to a boil and cook, stirring until the sauce is smooth and thick. Add salt and pepper to taste, whisk well, then remove from heat.
Spread 1/3 of Bolognese sauce over the bottom of a 9x13 baking dish.
Cover the Bolognese sauce in the base of the dish with 1/4 white sauce, followed by 4 sheets of lasagna. Repeat the layers twice more, then cover the top layer of lasagna with the remaining white sauce and sprinkle the grated Parmesan over the top.
Bake for 40-45 minutes or until the pasta feels tender when pierced with a fork. Let stand for 20 minutes before serving.
