Step‑by‑Step Instructions for Easy Creamy Spinach Mushroom Lasagna
Step 1: Prep Vegetable Filling
Start by heating 2 tablespoons of olive oil in a large skillet over medium heat. Add the sliced mushrooms and sauté for about 5 minutes, or until golden and tender. Next, stir in 3 cups of fresh spinach and 3 minced garlic cloves, cooking until the spinach is wilted and vibrant. Season with salt and pepper to taste, then remove the skillet from heat and set the filling aside.
Step 2: Make Béchamel Sauce
In a medium saucepan, melt 3 tablespoons of butter over low heat. Add 3 tablespoons of all-purpose flour to create a roux, cooking while stirring for about 1-2 minutes until it turns a light golden color. Gradually whisk in 3 cups of warm milk, stirring constantly until the sauce thickens and coats the back of a spoon, about 5-7 minutes. Finish with a sprinkle of ground nutmeg, salt, and pepper to taste.
Step 3: Prepare Noodles
If using no-boil lasagna noodles, follow the package instructions to prepare them, usually no cooking is required. If using traditional lasagna noodles, cook them according to the package until al dente, about 8-10 minutes, then drain and set aside. Having prepped noodles will ensure that your Easy Creamy Spinach Mushroom Lasagna layers come together smoothly.
Step 4: Assemble the Lasagna
Preheat your oven to 375°F (190°C). In a baking dish, spread a thin layer of the béchamel sauce on the bottom to prevent sticking. Begin layering your Easy Creamy Spinach Mushroom Lasagna by placing 3 noodles on top, followed by half of the vegetable filling, half of the ricotta cheese, and a layer of shredded mozzarella cheese. Repeat the layers, finishing with béchamel, mozzarella, and a sprinkle of grated Parmesan on top.
Step 5: Bake
Cover the assembled lasagna with foil and bake in the preheated oven for 25 minutes. After the first bake, remove the foil and continue baking for an additional 15 minutes or until the cheese is golden and bubbly. The enticing aroma will fill your kitchen, letting you know the lasagna is nearly ready! Allow it to rest for 10 minutes before slicing into this comforting Easy Creamy Spinach Mushroom Lasagna for clean servings.
