Steps to make lasagna with potatoes, sausage, and mushrooms

• To prepare the lasagna with potatoes, sausage, and mushrooms, first take the potatoes, peel them, wash them well under water, then slice them thinly with the help of a mandoline. Bring a pot of water and salt to the boil and blanch the potatoes for about 10 minutes. Meanwhile, prepare the sausage. Remove the casing from the sausage, then crumble it with your hands into a pan, without any seasoning, and let it brown. Drain the sautéed mushrooms from the oil and add them to the sausage and let them season, then add the chopped parsley if desired, mix well with a wooden spoon, then pour in the white wine, let it evaporate on high heat. Once it has dried out, the filling is ready.

• Drain the potatoes. Now let’s prepare the béchamel sauce. Melt the butter in a pot, add the all-purpose flour now and mix with a whisk, and when you have obtained a smooth and homogeneous consistency, you can add the whole milk gradually, continuing to mix. Then season the béchamel sauce with salt, black pepper, and nutmeg and let it thicken; it should not be too liquid nor too dense. Cook it on low heat for about 8 minutes. Now put the béchamel in a large bowl, set aside some for the base and surface. In the remaining béchamel, pour in the previously prepared sausage and mushrooms.

• Preheat the static oven to 356 degrees Fahrenheit. For the mozzarella, choose which one to use; I had the dry one for pizza, but if you want, you can also use classic mozzarella, in which case let it drain for at least 1 hour before using it.

  Now start assembling the lasagna. Take a baking dish and create a layer of plain béchamel on the bottom, then thin lasagna sheets, then sausage and mushroom béchamel, then blanched thin potato slices, mozzarella, and grated Parmesan cheese.

• Continue with all the layers in this way, first the sausage and mushroom béchamel, then the potatoes, mozzarella, and grated Parmesan cheese. Finally, cover the last layer with béchamel, potatoes, mozzarella, and breadcrumbs. A drizzle of extra virgin olive oil and bake.

• Bake at 356 degrees Fahrenheit and cook for about 30 minutes. Then, if you want, you can set it to grill mode for 5 minutes to brown the surface. Let it cool slightly, then serve.
