To prepare traditional Italian lasagna, begin with the foundation: fresh pasta. Combining flour and eggs in the right proportions is crucial for achieving the desired texture. Start with approximately 200 grams of flour per egg. On a clean surface, create a mound with the flour and make a well in the center for the eggs. Gradually incorporate the flour into the eggs, kneading the mixture until it reaches a smooth consistency. Once the dough has rested for about 30 minutes, roll it out using a pasta machine or a rolling pin, aiming for thin sheets, ideally around 1 mm thick.
Next, it is essential to prepare the sauces that will bring your lasagna to life. A classic Bolognese sauce begins with finely chopped onions, carrots, and celery, sautéed in olive oil until soft. Add ground meat—either a mixture of beef and pork—and cook until browned. Incorporate crushed tomatoes, salt, and a splash of red wine, allowing it to simmer for at least an hour to develop its rich flavors. For the béchamel sauce, melt butter in a saucepan, whisk in an equal portion of flour, and gradually add milk while stirring to avoid lumps. Season with nutmeg, salt, and pepper, creating a creamy, velvety texture.
With your components ready, it's time to assemble the lasagna. Begin by spreading a thin layer of béchamel in the baking dish. Place a layer of pasta sheets on top, followed by a generous portion of Bolognese sauce and a sprinkle of grated Parmigiano-Reggiano cheese. Repeat this layering process, ensuring that each layer is evenly distributed and not overcrowded. The final layer should be a top coat of béchamel and cheese to ensure a beautifully golden crust during baking.
Finally, bake your lasagna in a preheated oven at 180°C (350°F) for approximately 30 to 40 minutes, or until it bubbles and turns golden brown. Allow it to rest for at least 15 minutes before slicing, as this will help maintain the integrity of the layers. By sourcing high-quality ingredients and following these steps meticulously, you can recreate an authentic Italian lasagna that embodies tradition and flavor in every bite.
