Step‑by‑Step Instructions for Mushroom and Spinach Lasagna
Step 1: Prepare Vegetables
Heat a large skillet over medium heat and add a drizzle of olive oil. Sauté sliced mushrooms for 5-7 minutes until they are golden brown and tender. Add fresh spinach to the pan, stirring for another 2-3 minutes until wilted, then remove the mixture from heat and set aside. This vibrant mix will add depth to your Mushroom and Spinach Lasagna.
Step 2: Make Béchamel Sauce
In the same skillet, melt 4 tablespoons of butter over medium heat. Whisk in ¼ cup of all-purpose flour, stirring continuously for 2-3 minutes until it turns a light golden hue. Gradually add 3 cups of whole milk, whisking until the mixture thickens (about 5-7 minutes). Season with salt, pepper, and a pinch of nutmeg for an enhanced flavor that beautifully complements the layers of your Mushroom and Spinach Lasagna.
Step 3: Assemble Lasagna
Preheat your oven to 375°F (190°C). In a 9x13 inch baking dish, spread a layer of béchamel sauce at the bottom. Place a layer of no-boil lasagna noodles over the sauce, then add half of the sautéed mushroom and spinach mixture. Top with more béchamel and a sprinkle of mozzarella cheese. Repeat the layering process, finishing with a final layer of noodles, béchamel, and a generous topping of mozzarella and parmesan cheese.
Step 4: Bake
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 30 minutes until the lasagna is bubbling. After 30 minutes, remove the foil and bake for an additional 15-20 minutes until the top is golden and melted, creating a beautiful crispy layer on your Mushroom and Spinach Lasagna.
Step 5: Cool and Serve
Once baked, remove the lasagna from the oven and let it rest for 10-15 minutes. This allows the layers to set, making it easier to slice into perfect portions. Serve your warm Mushroom and Spinach Lasagna alongside garlic bread or a fresh salad for a complete, comforting meal that everyone will love.
Make Ahead Options
This Mushroom and Spinach Lasagna is perfect for busy home cooks looking to save time during the week! You can prepare the béchamel sauce and sauté the mushrooms and spinach up to 24 hours in advance, storing them in airtight containers in the refrigerator to maintain freshness. For even more convenience, assemble the lasagna completely and refrigerate it for up to 3 days ahead of baking. When you’re ready to enjoy your delicious lasagna, simply bake it straight from the fridge, adding an extra 10-15 minutes to the cooking time to ensure it's heated through thoroughly. This way, you can indulge in a comforting meal with minimal effort on busy nights!
