Step‑by‑Step Instructions for Spinach and Mushroom White Lasagna
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While it’s heating, grease a 9×13 inch baking dish with a thin layer of olive oil or butter to prevent sticking. This will ensure your Creamy Spinach and Mushroom White Lasagna slides out easily when it’s time to serve.
Step 2: Sauté Aromatics
In a large skillet over medium heat, melt 2 tablespoons of olive oil or butter. Add one finely chopped onion and 2 cloves of minced garlic, sautéing for about 3-4 minutes until they’re soft and fragrant. This delicious aromatic base is crucial for enhancing the flavors of your lasagna.
Step 3: Cook Mushrooms and Spinach
Stir in 8 ounces of sliced mushrooms, cooking for another 5-7 minutes until they’re browned and their moisture is evaporated. Afterward, add 4 cups of fresh spinach, stirring until it wilts, which should take about 2-3 minutes. Season this filling with salt and pepper to taste, bringing out the earthiness of the mushrooms and the freshness of the spinach.
Step 4: Prepare the Ricotta Mixture
In a medium bowl, combine 15 ounces of ricotta cheese with an optional egg, a handful of grated Parmesan, and a pinch of salt and pepper. Mix thoroughly until the ingredients are well incorporated. This creamy ricotta mixture will provide a hearty texture in your lasagna, balancing the lightness of the vegetables.
Step 5: Make the Béchamel Sauce
In a saucepan, melt 4 tablespoons of butter over medium heat. Whisk in ¼ cup of all-purpose flour until smooth, cooking for about 1-2 minutes to form a roux. Gradually add 2 cups of whole milk, continuously whisking for 5-7 minutes until the sauce thickens. Season your béchamel with salt, pepper, and a hint of nutmeg for added warmth.
Step 6: Assemble the Lasagna
Begin layering in your greased baking dish with a spoonful of béchamel sauce at the bottom. Place a layer of lasagna noodles on top, followed by half of the ricotta mixture, half of the sautéed mushroom and spinach filling, and a sprinkle of shredded mozzarella cheese. Repeat these layers, finishing with noodles and topping everything with remaining béchamel, mozzarella, and a generous sprinkle of Parmesan.
Step 7: Bake the Lasagna
Cover the assembled Spinach and Mushroom White Lasagna with foil and place it in the preheated oven. Bake for 25 minutes covered, then remove the foil and bake for an additional 15-20 minutes, or until the top is golden and bubbly. The house should fill with the tantalizing aroma of your delicious creation!
Step 8: Rest and Serve
Once removed from the oven, let the lasagna rest for 10-15 minutes before slicing. This resting period allows the layers to set beautifully, ensuring neat slices when serving. Enjoy this comforting dish warm, garnished with fresh herbs or more Parmesan as desired.
