Step 2: Make the Béchamel Sauce
- In a medium saucepan, melt the butter over medium heat.
- Add the flour and whisk constantly for 1-2 minutes until it forms a smooth paste (roux).
- Gradually add the warm milk, whisking constantly to prevent lumps.
- Cook for 5-7 minutes, stirring frequently, until the sauce thickens.
- Season with nutmeg, salt, and pepper. Stir in the Parmesan cheese until melted and smooth.
Step 3: Assemble the Lasagna
- Preheat your oven to 375°F (190°C). Grease a 9×13-inch (23×33 cm) baking dish.
- Spread a thin layer of béchamel sauce on the bottom of the dish.
- Add a layer of lasagna sheets.
- Spread a portion of the mushroom filling over the pasta, followed by a layer of béchamel sauce.
- Sprinkle a handful of mozzarella cheese over the sauce.
- Repeat the layers: pasta, mushrooms, béchamel, mozzarella, until all ingredients are used, finishing with a layer of béchamel sauce on top.
- Sprinkle the remaining Parmesan cheese over the top layer.
Step 4: Bake the Lasagna
- Cover the dish with aluminum foil (to prevent the top from over-browning) and bake for 25 minutes.
- Remove the foil and bake for an additional 15-20 minutes until the top is golden and bubbly.
- Let the lasagna cool for 10-15 minutes before slicing and serving.
Tips for Success
- Mushroom Variety: For a richer flavor, use a mix of wild mushrooms such as shiitake, oyster, or porcini.
- Add Herbs: Fresh parsley or basil can be added to the layers for extra aroma.
- Cheese Swap: For extra creaminess, include ricotta or mascarpone in the layers.
- Make Ahead: Assemble the lasagna in advance and refrigerate. Bake just before serving.
