How to Make Creamy Spinach Mushroom Lasagna
- Prepare vegetables: Start by heating olive oil in a pan, then sauté the mushrooms and garlic over medium heat until golden brown and aromatic, about 5-7 minutes. Meanwhile, wilt the fresh spinach in another pan until just tender, which should take about 2-3 minutes, to ensure it adds flavor without excess moisture.
- Make béchamel sauce: In a separate saucepan, melt butter over low heat. Whisk in flour for about 1-2 minutes to create a roux, then gradually add milk while stirring continuously. Keep stirring until the mixture thickens, typically around 5-7 minutes. Season your béchamel with salt, pepper, and a pinch of nutmeg, if desired.
- Layer the lasagna:
- Start with béchamel: Spread a thin layer of béchamel sauce on the bottom of a greased baking dish.
- Add lasagna sheets: Place a layer of cooked lasagna noodles on top, then spoon more béchamel over the noodles.
- Add fillings: Layer sautéed mushrooms, wilted spinach, and a mixture of mozzarella, ricotta, and Parmesan cheeses.
- Repeat: Continue layering noodles, béchamel, fillings, and cheeses, ensuring to finish with a generous topping of cheese.
- Bake: Preheat your oven to 350°F (175°C). Cover the lasagna with foil and bake for 30 minutes. Afterward, remove the foil and bake for an additional 10-15 minutes, allowing the cheese to get golden and bubbly.
- Rest: Once baked, allow the lasagna to rest for about 10-15 minutes before slicing. This way, the layers will set, making serving neat and easy.
Optional: Sprinkle fresh herbs on top before serving for an added burst of flavor.
