I make my lasagne without the traditional carrots/ celery/ onions of a bolognese. I use an entire head of garlic.
Minced beef, sometimes with minced pork but not always.
15 Oz tin of crushed tomatoes plus a few Tbsp tomato puree
Some water to rinse out the can
Red Wine
S&P
Dried basil and oregano
A little nutmeg
Brown the meat in a little splash of oil, medium heat
Drain/ scoop off most of the rendered fat
Add minced garlic and stir around for a few mins, low heat
Add a sprinkle of nutmeg
Add red wine with pot on high heat
Let evaporate for a few mins, bubbling away
Add crushed tomatoes (if you can't buy crushed tomatoes, put 15ozs tinned tomatoes in the blender and add puree, then whiz it)
Rinse can with a little water; add to pot
Add dried herbs, S&P
Bring to a boil for a few mins then turn to simmer for an hour
For bechamel, make a roux, add any milk to make about 8 cups of sauce. Add a sprinkling of nutmeg, S&P, and a green onion/ scallion/ spring onion and bay leaf, stirring and simmering as it thickens.
Butter your dish, place lasagne sheets directly on the bottom, add meat sauce, sheets of lasagne, bechamel (discard onion and bay leaf), sheets of lasagne, meat sauce, sheets of lasagne, bechamel, oregano, grated cheese to completely cover the top.
If your meat sauce thickened up too much and it looks as if there are gaps/ dry patches in your unbaked lasagne, add 2 cups of red wine around the sides so there's plenty of liquid for the lasagne sheets to absorb and soften (I use dry sheets).
Bake 35-40 mins in medium high oven ( I'm in US and set my oven to 350-375 F).
