Step‑by‑Step Instructions for Cozy Creamy Spinach Mushroom Lasagna
Step 1: Prepare the Béchamel Sauce
In a saucepan over medium heat, melt 4 tablespoons of butter until bubbly. Whisk in 4 tablespoons of flour, stirring continuously for about 2 minutes until golden. Gradually add 4 cups of milk, stirring constantly to avoid lumps. Cook for 5-7 minutes, until the béchamel thickens and coats the back of a spoon. Stir in a pinch of nutmeg, then remove from heat and set aside.
Step 2: Sauté the Vegetables
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add 2 minced garlic cloves, sautéing them for 1 minute until fragrant. Toss in 8 ounces of sliced mushrooms, cooking for about 5 minutes until they’re beautifully browned. Finally, add 4 cups of fresh spinach and stir for 2 minutes until wilted. Remove from heat and let the vegetable mixture cool slightly.
Step 3: Assemble the Lasagna
Preheat your oven to 375°F (190°C). In a 9×13 inch baking dish, spread a thin layer of the béchamel sauce at the bottom. Layer in 3 lasagna noodles, half of the mushroom-spinach mixture, and 1 cup of shredded mozzarella cheese. Repeat the layers one more time, topping with a final layer of béchamel and a generous sprinkle of mozzarella and grated Parmesan cheese.
Step 4: Bake the Lasagna
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 30 minutes to ensure the noodles cook through and the flavors meld beautifully. After 30 minutes, remove the foil and bake uncovered for an additional 15 minutes, or until the top is golden brown and bubbling with deliciousness.
Step 5: Rest and Serve
Once baked, take the lasagna out of the oven and allow it to rest for about 10 minutes. This helps the layers set for easier slicing. Cut into squares and serve warm, optionally garnished with fresh herbs, as you enjoy the comforting flavors of your Cozy Creamy Spinach Mushroom Lasagna.

Expert Tips for Cozy Creamy Spinach Mushroom Lasagna
-
Béchamel Consistency: Make sure your béchamel sauce is thick enough to hold the layers together, which enhances the overall texture of the cozy creamy spinach mushroom lasagna.
-
Season to Taste: Always taste the béchamel and vegetable mixture while cooking to adjust the seasoning. A dash of extra salt or pepper can elevate the flavor beautifully.
-
Avoid Overcooking: Keep an eye on the mushrooms while sautéing them; overcooked mushrooms can become rubbery. Aim for a golden brown color with a tender bite.
-
Layering Smart: Start with a thin béchamel layer before the noodles to prevent sticking. This helps maintain a delightful structure and eases slicing later on.
-
Rest Before Serving: Let the lasagna rest for at least 10 minutes after baking. This allows it to set and makes it easier to cut while preserving the layers intact.
Make Ahead Options
These Cozy Creamy Spinach Mushroom Lasagna layers are perfect for meal prep, saving you precious time on busy weeknights!

Cozy Creamy Spinach Mushroom Lasagna Recipe FAQs

Absolutely! For this recipe, I recommend using Cremini or Button mushrooms as they both have a delightful earthy flavor. If you want a unique twist, consider substituting with roasted red peppers that can add a sweet contrast to the creamy béchamel. Always look for firm mushrooms without dark spots, as these can indicate overripeness.

Of course! To freeze, wrap the assembled but unbaked lasagna tightly in plastic wrap, then foil to prevent freezer burn. It can be frozen for up to 3 months. When you’re ready to bake it, thaw it overnight in the fridge and then bake at 375°F (190°C) for about 45-50 minutes, until heated through and bubbling.
What should I do if my béchamel sauce is too thin?
If your béchamel sauce ends up too runny, don’t worry! Return it to low heat and mix 1 tablespoon of flour with a little milk to create a slurry. Gradually whisk this into the sauce, cooking for a few more minutes until thickened. This will help achieve that luscious, creamy texture that holds the lasagna layers together beautifully.
Are there any dietary considerations I should be aware of with this recipe?
Absolutely! If you’re preparing this lasagna for someone with dietary restrictions, consider using almond or oat milk for a dairy-free version of the béchamel.
