Bring a pot of salted water to a boil with the laurel leaf and some juniper berries. Add the asparagus and cook for about 10 minutes. Drain, remove the hard part of the asparagus stems and cut into pieces.
Whisk the egg into the already made bechamel sauce and then gently mix in the asparagus.
Cut the sheet of pasta into squares about 4" wide, obtaining 12 to 16 pieces. Bring a pot of salted water to a boil. Drop the squares in and cook until "al dente" or firm. Remove them with a slotted spoon and place them on a clean cotton cloth.
In 4 oven proof dinner dishes layer some of the béchamel sauce, a pasta square, some grated
Asiago cheese, some more sauce, and continue until all the ingredients are finished.
Place the dishes in a 350°F oven for ten minutes and serve.
