  • Preheat oven to 400°F. For the Bechamel sauce, melt butter in a saucepan, sprinkle in the flour and cook and stir 5 mins. Pour in milk and stock while continuing to stir. Add bay leaves and rosemary and simmer 10 mins, stirring occasionally. Remove herbs, add the Parmesan and season.
  • Meanwhile, for the filling, blanch spinach in boiling salted water 2 mins. Drain and rinse. Heat 1 tbsp oil in a frying pan and saute onion and garlic until soft. Add the spinach and season. Remove from heat and set aside. Heat remaining oil in a pan and saute the mushrooms until soft. Remove from heat and set aside.
  • Pour a little Bechamel into an 8 x 12 inch ovenproof dish. Lay 3 lasagna sheets next to each other in the dish, spread with Bechamel, then top with spinach and mushrooms. Spread a little Bechamel on the mushrooms, then add another layer of lasagna sheets. Repeat with remaining Bechamel, spinach and mushrooms, finishing with a layer of lasagna sheets, some bechamel and a few mushrooms. Bake 45 mins to 1 hour. Serve hot.
