I always use Prue Leith's lasagne verdi recipe...goes down a treat every time
Recipe taken from Prue Leith's cookery bible (every cook should have it!)
For the meat sauce:
1 tablespoon dripping or oil
340g/12 oz lean minced beef
1 onion, finely diced
1 stick celery, finely diced
4 cloves garlic, chopped
30g/1oz plain flour
290 ml/1/2 pint good brown stock
100ml/ 3 1/2 fl oz white wine (dry)
salt and freshly ground black pepper
1 tablespoon freshly chopped parsley
1 teaspoon chopped fresh marjoram
a pinch of ground cinnamon
1 tablespoon tomato puree
For the cream sauce:
45g / 1 1/2 oz butter
1 bay leaf
45g/ 1 1/2 oz plain flour
570 ml/ 1 pint creamy milk
salt and freshly ground black pepper
freshly grated nutmeg
Method:
Heat thre drippoing or oil in a saucepan and brown the meat well. Add the vegetables and garlic and fry, stirring continuously for 2 minutes.
Stir in the flour. Cook for 30 seconds. Pour in the stock and wine and add the salt and pepper, parsley, marjoram, cinnamon and tomato puree. Bring to the boil, stirring. Simmer slowly for 45 minutes, then boil rapidly, stirring until the sauce has thickened and is syrupy.
Make the cream sauce: melt the butter in a saucepan, add the bayleaf and flour and cook, stirring for one minute. Remove from the heat.
Add the milk and return to the heat. Bring slowly to the boil, stirring continuously, until you have a thick, creamy sauce. Simmer for 2 minutes, season with salt and pepper and remove the bayleaf.
Preheat the oven to gas mark 5.
Butter an ovenproof dish and cover the bottom with a layer of pasta, then spoon on a thin layer of meat sauce. Cover with a layer of cram sauce. Arrange a layer of pasta on top of this. Continue in this manner, finishing with a layer of cream sauce. Sprinkle with grated parmesan cheese.
Bake in the preheated oven for 20-25 minutes until bubbling and just brown on top. (If using bought pasta, cook to the manufacturer's instructions.).
