If the mushrooms are fresh, start by cleaning them. Cut off the lower part of the stem, immerse them in water and washing them thoroughly without breaking them until clean of any soil.
Pat the mushrooms dry with a cloth and cut them into pieces (see photo on page 1).
If you are using dried porcini, you need to soak them in a bowl with warm water for at least half an hour and then drain them.
Put two tablespoons of extra virgin olive oil into a non-stick frying pan and heat
When the oil is hot add one or two peeled garlic cloves (as desired)
Add the mushrooms and let them brown a little.
Lower the flame and add the white wine, a handful of chopped parsley, salt and pepper.
Let the mushrooms cook for about 40 minutes until they are soft.
If the sauce gets too dry, add more wine or some vegetable broth.
In the meantime make the béchamel.
Add a little bit of béchamel to the mushroom sauce.
Turn off the flame and let the mushrooms marinate.
Remove the garlic from the frying pan.
Cut the outer part of burrata into small pieces in a bowl so that you can keep the stracciatella (the soft part inside of the cheese) in the bowl and put it aside.
Grease an oven dish with butter.
Fill the bottom with lasagne sheets (precooked to not quite al dente if dried)
Add some béchamel and mushrooms, cover with burrata pieces and grated cheese
Continue to layer until all the lasagne have been used and the dish is almost full
Finish by covering the last layer with the last of the béchamel, the stracciatella (the creamy mixture from inside the burrata), the remaining grated cheese and some small bits of butter
Bake at 180 ° for about 30 minutes.
When ready allow the dish to stand for 5 minutes before serving.
