Step‑by‑Step Instructions for Creamy Spinach Mushroom Lasagna
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, gather all your ingredients, ensuring easy access as you prepare. This initial step sets the stage for your Creamy Spinach Mushroom Lasagna, letting the cooking magic begin as soon as you’re ready to assemble.
Step 2: Sauté the Vegetables
In a large skillet over medium heat, drizzle some olive oil and sauté your chopped mushrooms for about 5 minutes until they soften and begin to brown. Then, add the fresh spinach, cooking until wilted, around 2-3 minutes more. Season the mixture with salt and pepper to taste before removing it from heat and setting it aside.
Step 3: Prepare the Béchamel Sauce
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Whisk in 4 tablespoons of flour to create a roux and cook for 1-2 minutes. Gradually add 4 cups of milk, whisking continuously until the béchamel thickens to a creamy consistency, around 5-7 minutes. Season with salt, pepper, and a pinch of nutmeg for an aromatic touch.
Step 4: Layer the Lasagna
In a 9×13 inch baking dish, start layering your Creamy Spinach Mushroom Lasagna. Begin with a layer of noodles, followed by a third of the béchamel sauce. Then, spread half of the sautéed spinach and mushrooms on top, followed by a generous sprinkle of mozzarella cheese. Repeat the layers, finishing with a final layer of noodles, béchamel, and cheese.
Step 5: Bake Until Golden
Cover your assembled lasagna with aluminum foil, shiny side up, and bake in the preheated oven for 30 minutes. After this time, remove the foil to allow the top to brown. Continue baking for an additional 10-15 minutes, or until the cheese is bubbly and golden brown.
Step 6: Let It Rest
Once out of the oven, let your lasagna cool for about 10 minutes. This resting period helps the layers set, making it easier to slice. The rich aroma of your Creamy Spinach Mushroom Lasagna will fill the air, inviting everyone to the table for a heartwarming meal.
