On a warm summer day, white lasagna emerges as a dish that celebrates the fresh seasonal vegetables, paying homage to the rich culinary tradition of Sicily. This dish, characterized by a creamy and enveloping texture, is an alternative to classic lasagna with ragù, offering a meeting of delicate and fresh flavors, where potatoes and zucchini harmoniously blend with the cooking cream. The choice to use these ingredients is not casual: zucchini, with their light flavor and tender texture, lend themselves beautifully to creating a tasty base, while the potatoes provide a creaminess that makes every layer irresistible. The preparation involves slow cooking, allowing the flavors to meld perfectly; the cream obtained from the blended vegetables offers a velvety result, capable of embracing the sheets of pasta in a comforting way. In Sicily, where the gastronomic tradition is rich in vegetable-based dishes, white lasagna represents a highly appreciated summer variant, ideal for family lunches or dinners among friends. This dish finds its perfect place on festive tables, but it is also an excellent solution for using up leftover vegetables, transforming them into a flavorful and satisfying meal. A final touch of pistachios, chopped and sprinkled on the surface, not only adds an unexpected crunch but also evokes the scents of the Sicilian land, further enriching the tasting experience. Thus, white lasagna is a dish that celebrates the freshness and genuineness of the ingredients, perfect for making any occasion special.

Peel the potatoes and cut them into chunks, wash the zucchini and cut them into chunks as well, and do the same with the onion. Fill with water until covered, add the bouillon cubes, and cook on low heat. Then, add the cream, blend everything with an immersion blender to create a creamy mixture. In a baking dish, place a ladle of the cream and arrange the sheets of pasta, add another ladle of cream, and sprinkle with ground pistachios and Parmesan cheese. Repeat this until the edge. Bake at 250°C for 30 minutes.
