Step‑by‑Step Instructions for White Lasagna with Spinach and Mushrooms

Step 1: Prepare the Béchamel Sauce
In a medium saucepan, melt 4 tablespoons of unsalted butter over medium heat. Once melted, add 2 minced garlic cloves and sauté until fragrant, about 1 minute. Stir in 1/4 cup of all-purpose flour to create a roux, cooking for 2 minutes. Gradually whisk in 2 cups of half and half and 1 cup of whole milk until smooth. Cook for another 5–7 minutes until the sauce thickens and coats the back of a spoon. Mix in 1 cup of grated Parmesan, salt, black pepper, and a pinch of nutmeg.

Step 2: Sauté Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Add 8 ounces of sliced baby bella mushrooms, sautéing for about 5 minutes until softened and slightly browned. Next, stir in another clove of minced garlic and cook for 1 minute more. Add 4 cups of fresh baby spinach, cooking until wilted, approximately 2–3 minutes. Remove from heat and allow the mixture to cool slightly before proceeding.

Step 3: Make Cheese Mixture
In a mixing bowl, combine 15 ounces of whole milk ricotta cheese, 1 cup of shredded mozzarella cheese, 2 large eggs, and a pinch of salt and pepper. Gently fold in the sautéed mushroom and spinach mixture until evenly distributed. This creamy filling will be layered into the lasagna, contributing to the dish’s rich flavor and texture.

Step 4: Assemble Lasagna
Preheat your oven to 375°F (190°C). Grease a 9×13 inch casserole dish and begin layering your White Lasagna with Spinach and Mushrooms: spread a thin layer of béchamel sauce on the bottom, followed by a layer of oven-ready lasagna noodles. Next, spoon half of the cheese mixture over the noodles, then add another layer of sauce. Repeat these layers, finishing with a final layer of noodles topped with the remaining sauce and an additional sprinkle of shredded mozzarella.

Step 5: Bake
Cover the casserole dish with foil and bake in the preheated oven for 50 minutes. After that time, remove the foil to allow the top to brown, and bake for an additional 10 minutes or until the cheese is bubbly and golden. Keep an eye on it towards the end to ensure it doesn’t over-brown.

Step 6: Cool Before Serving
Once baked, remove the white lasagna from the oven and let it rest for at least 15 minutes. This cooling period allows the layers to set, making it easier to cut and serve. The creamy filling and soft noodles will meld beautifully, creating the perfect comforting dish to enjoy with family and friends.

White Lasagna with Spinach and Mushrooms Recipe FAQs

How do I select the best spinach for my lasagna?
Absolutely! Look for fresh baby spinach with vibrant green leaves and no wilting or dark spots. This ensures you’re getting the freshest flavor and maximum nutrients. If using frozen spinach, select one without added sauces or sodium.

What’s the best way to store leftover white lasagna?
Very! Store leftover white lasagna in an airtight container in the fridge for up to 3 days. Allow it to cool completely before sealing to prevent any moisture buildup, which can make the noodles soggy.

Can I freeze my white lasagna, and how should I do it?
Yes! You can freeze your fully assembled White Lasagna with Spinach and Mushrooms for up to 2 months. To freeze, wrap it tightly with plastic wrap, then cover with aluminum foil. When you’re ready to enjoy it, thaw in the fridge overnight before baking.

Why is my béchamel sauce not thickening properly? What can I do?
Very common! If your béchamel isn’t thickening, make sure you’re cooking the flour long enough (at least 2 minutes) before adding the liquid. If it’s still too thin, you can mix a bit of cornstarch with cold water to create a slurry, then whisk it into the sauce while it simmers. This should help you achieve that luscious creamy texture.

Are there any dietary considerations for this recipe?
Yes! For a gluten-free version, use gluten-free oven-ready lasagna noodles. If you’re looking for a dairy-free option, you can substitute the béchamel with a cashew or coconut cream base and use vegan cheeses. Always double-check labels to ensure none of the ingredients contain allergens if you’re cooking for someone with food sensitivities.

What’s the best way to ensure my lasagna doesn’t turn out soggy?
Absolutely! Layer your ingredients mindfully. Always use enough béchamel sauce to moisten the noodles without making them soggy. Ensure that the vegetables are sautéed just until tender, not too soft, which can release excess moisture. Also, allow your lasagna to cool for at least 15 minutes before slicing—it will hold its shape better and be easier to serve!
