Step‑by‑Step Instructions for Cozy Creamy Spinach Mushroom Lasagna
Step 1: Prepare Béchamel
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Once melted, whisk in 4 tablespoons of flour to form a roux, cooking for about 2 minutes until bubbly. Gradually pour in 3 cups of milk, stirring constantly until the mixture thickens, about 5 to 7 minutes. Finish by adding a pinch of nutmeg, then remove from heat and set aside.
Step 2: Sauté Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Add 2 minced garlic cloves and sauté for 1 minute until fragrant. Next, add 8 ounces of sliced mushrooms and cook for about 5 minutes, stirring occasionally, until they turn a golden brown. Finally, incorporate 4 cups of fresh spinach, stirring until wilted, which should take around 2 minutes.
Step 3: Layer Lasagna
Preheat your oven to 375°F (190°C). In a baking dish, start with a layer of the béchamel sauce at the bottom. Place a layer of lasagna noodles on top, followed by half of the mushroom-spinach mixture and a generous sprinkle of mozzarella cheese. Repeat the layers, finishing with béchamel and a final topping of mozzarella and parmesan cheese.
Step 4: Bake
Cover your layered lasagna with aluminum foil and bake in the preheated oven for 30 minutes. After that, carefully remove the foil and bake for an additional 15 minutes. You’ll know it’s ready when the cheese is golden brown and bubbly, enticing everyone with its delicious aroma.
Step 5: Rest & Serve
Once out of the oven, let your Cozy Creamy Spinach Mushroom Lasagna rest for about 10 minutes. This allows the layers to set before slicing, making it easier to serve. Slice into portions and serve warm, optionally garnished with fresh herbs for added color and flavor.

• Garlic Adjustments: If you’re sensitive to garlic, simply omit it. The dish will still be flavorful because of the creamy béchamel and mushrooms.
• Layering Strategy: Layering cheese in between mushroom and spinach creates a cozy creamy texture. Don’t be shy with the cheese for that melty goodness!

Cozy Creamy Spinach Mushroom Lasagna Recipe FAQs
How do I choose the right spinach for my lasagna?

What should I do if my béchamel sauce is too runny?
No worries! If your béchamel sauce turns out runny, simply return it to the stove over medium heat, whisking continuously until it thickens to a creamy consistency. If needed, you can also whisk in a bit more flour (mixed with a little milk) to help thicken it up. Keep watching the sauce closely to avoid burning!
Is this recipe suitable for those with dietary restrictions?
