• Flour – All-purpose flour is standard, but use gluten-free flour for a gluten-free béchamel.

Step‑by‑Step Instructions for Spinach and Mushroom White Lasagna

Step 1: Prepare the Béchamel Sauce
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Gradually whisk in 4 tablespoons of flour and cook for about 1-2 minutes until slightly golden. Slowly pour in 4 cups of milk, whisking continuously for 5-7 minutes or until the mixture thickens and is smooth. Season the béchamel sauce with salt and pepper to taste, then remove from heat.

Step 2: Sauté the Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Add 8 ounces of sliced mushrooms and sauté for about 5-7 minutes until they’re nicely browned and tender, releasing their moisture. Next, add 4 cups of fresh spinach, cooking until wilted, around 2-3 minutes. Remove the skillet from heat, and set the sautéed vegetables aside.

Step 3: Layer the Lasagna
Preheat your oven to 375°F (190°C). In a 9×13 inch baking dish, start by spreading a thin layer of the béchamel sauce on the bottom. Add a layer of lasagna noodles, followed by a portion of the sautéed spinach and mushrooms, and a sprinkle of your cheese blend. Repeat this process, finishing with a layer of noodles topped with béchamel sauce and an extra layer of cheese for that gooey goodness.

Step 4: Bake the Lasagna
Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes. After that, remove the foil and continue to bake for an additional 15-20 minutes, or until the top is golden brown and bubbly. Keep an eye on the lasagna; it should be irresistible with a toasty, delicious aroma filling your kitchen.

Step 5: Rest Before Serving
Once baked, take the Spinach and Mushroom White Lasagna out of the oven and allow it to rest for 10-15 minutes. This resting period is crucial for letting the layers set, making it easier to slice. After resting, you’ll be rewarded with perfectly formed pieces that hold their shape, ready to serve to your eager guests.

How to Store and Freeze Spinach and Mushroom White Lasagna

Fridge: Store uneaten lasagna in an airtight container for up to 3 days, ensuring it retains its creamy texture for your next meal.

Freezer: Wrap slices tightly in plastic wrap and then in aluminum foil, freezing for up to 3 months to preserve flavor and freshness.
