Lasagne Al Forno - cooking recipe

Ingredients

1 lb lasagna noodle
14 ounces mozzarella cheese (diced)
4 ounces parmigiano-reggiano cheese
For the Ragu Bolognese
12 ounces ground beef
12 ounces ground pork
200 g pancetta
4 tablespoons extra virgin olive oil
1 large white onion, chopped
2 large garlic cloves (chopped , I double this)
630 g italian chopped tomatoes
6 tablespoons tomato puree
6 fluid ounces red wine
whole nutmeg
salt
fresh ground black pepper
15 g fresh basil
Bechamel Sauce
6 cups milk
6 ounces butter
4 ounces flour
salt
pepper
2 large garlic cloves, minced
6 fluid ounces heavy cream or 6 fluid ounces double cream

Preparation

In a large saute pan, heat 1 tablespoon oil over medium heat. Add onion and fry for about 10 minutes.
While the onion is cooking, chop the pancetta. The best way to do this is to roll it up, cut lengthwise then across.
Once onion is softened, add the pancetta and cook for another 5 minutes.
Place the pancetta and onion in a 6 quart dutch oven, add another tablespoon of oil to the saute pan and return to heat.
Add the ground beef and cook until browned. Transfer to the dutch oven, add another tablespoon of oil to pan and return to heat.
Add the ground pork and brown.
Once pork has browned, add it to the dutch oven.
Preheat oven to 275\u00b0F (140\u00b0C, Gas Mark 1).
Place dutch oven on burner and stir ingredients together. Add the tomatoes, tomato puree, red wine, salt, pepper, and about 1/4 nutmeg, grated. Stir all ingredients together and bring to a simmer.
While bringing mixture to a simmer, tear half of the basil leaves from the stem, tear or chop the leaves and add them to the pot. As soon as the mixture is simmering, place in preheated oven. You do not need to cover the mixture.
Here the recipe says to let simmer for 3 hours before giving a stir, I stirred every 45 minutes.
When liquid has reduced to a concentrated sauce, season to taste with salt and pepper and add the remainder of the basil.
About 20-30 minutes before the ragu bolognese is due to come out of the oven, begin the bechamel sauce.
Place the milk, butter, flour, salt and pepper, and garlic in a large saucepan. Heat oven medium-low heat and whisk until simmering and thickened. Reduce heat as low as possible and simmer for 10 minutes more.
Sieve the sauce into a large bowl and add the cream. Adjust seasoning and add another quarter of nutmeg.
Preheat oven to 350\u00b0F (Gas mark 4, 180\u00b0C).
Now for the assembly. Organize your materials in the order in which you will use them, with the baking dish on a cookie sheet (to catch spillage) in the middle.
Spread a thin layer of the ragu bolognese on the bottom of the pan. Cover with 1/4 of the bechamel sauce, diced mozzarella and a sprinkling of Parmesan cheese. Add a layer of lasagna noodles (They don't need to be cooked, the large amount of sauce cooks the noodles). Repeat in this manner, finishing off with a top layer of cream sauce and a coating of Parmesan cheese.
Place in oven (be sure to keep the baking sheet underneath!) and bake for 45-50 minutes or until golden brown and bubbling.
