Step-by-Step Instructions

H2: Build the Best Creamy Spinach Mushroom Lasagna

H3: Step 1 – Cook the Vegetables

Warm the olive oil in a large skillet set over medium heat. Add the chopped onion and sauté until soft, about 3-4 minutes. Stir in the garlic and let it release its aroma for roughly a minute. Add the mushrooms and cook until their moisture evaporates and they begin to brown—around 7-10 minutes. Fold in the spinach and cook until it wilts down. Add salt and pepper to taste, then take off the heat and set aside.

H3: Step 2 – Make the Creamy Béchamel Sauce

In a separate saucepan, melt the butter on medium heat. Sprinkle in the flour and whisk continuously for 2 minutes to create a smooth base. Gradually pour in the milk while whisking steadily to keep the sauce lump-free. Continue stirring until the sauce becomes thick and creamy, about 5-7 minutes. Mix in the Parmesan and nutmeg. Finish by seasoning with salt and pepper.

H3: Step 3 – Assemble the Lasagna

Preheat your oven to 375°F (190°C). Lightly coat the bottom of a 9×13 inch baking dish with some of the béchamel sauce. Place 3-4 noodles across the bottom, followed by a layer of the mushroom-spinach mixture. Drizzle more sauce over the top and sprinkle with mozzarella. Continue layering until all ingredients are used, ending with a final coat of sauce and a generous dusting of Parmesan.

H3: Step 4 – Bake to Golden Perfection

Wrap the baking dish with aluminum foil and bake for about 25 minutes. Uncover and continue baking for another 15-20 minutes, or until the top is lightly golden and bubbling. Let the Creamy Spinach Mushroom Lasagna cool for 10-15 minutes before serving to allow it to set perfectly.

Tips for an Unforgettable Creamy Spinach Mushroom Lasagna

• Use fresh spinach for the best flavor and texture, but frozen works too if well-drained.
• Don’t rush the sauce. Give it time to thicken properly so your lasagna isn’t watery.
• Mozzarella melts best when shredded fresh—pre-shredded cheese doesn’t melt as smoothly.
• Let it rest before slicing to avoid a soupy lasagna.

Make It Your Own

This Creamy Spinach Mushroom Lasagna is highly customizable:

• Add ricotta cheese between layers for extra creaminess.
• Use a blend of mushrooms like shiitake and portobello for deeper flavor.
• Swap béchamel for Alfredo if you’re short on time.
• Try adding sun-dried tomatoes or roasted red peppers for a flavor twist.

Perfect Pairings

To elevate your Creamy Spinach Mushroom Lasagna experience, serve it with:

• A crisp arugula salad with lemon vinaigrette
• Garlic knots or crusty sourdough bread
• A glass of Pinot Grigio or light-bodied red wine
