Step‑by‑Step Instructions for Mushroom and Spinach Lasagna
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). Meanwhile, generously grease a 9×13-inch baking dish with olive oil or cooking spray. This preparation will ensure that your delicious Mushroom and Spinach Lasagna releases easily after baking, allowing for beautifully intact slices when serving.
Step 2: Cook Noodles
In a large pot, bring salted water to a rolling boil. Carefully add lasagna noodles and cook them until they are al dente, typically around 8-10 minutes, stirring occasionally to prevent sticking. Once done, drain the noodles in a colander and set them aside, ensuring they do not stick together as you prepare the filling.
Step 3: Prepare Filling
Drizzle olive oil in a large skillet over medium heat, and add chopped onions. Sauté for about 3-4 minutes, or until onions turn translucent—a sign that their sweetness is releasing. Stir in minced garlic and cook for an additional minute before adding sliced mushrooms, dried thyme, salt, and pepper. Sauté until mushrooms are tender, about 5-7 minutes. Finally, add fresh spinach, stirring until wilted; this will create a flavorful filling for your lasagna.
Step 4: Assemble Lasagna
Spread a thin layer of marinara sauce across the bottom of your greased baking dish. Begin layering your Mushroom and Spinach Lasagna by placing three cooked noodles horizontally. Spoon half of the ricotta cheese mixture over the noodles, followed by half of the sautéed mushroom and spinach mixture, and a generous sprinkle of mozzarella cheese. Repeat this process, finishing with a final layer of noodles topped with remaining marinara sauce and cheeses.
Step 5: Bake
Cover the assembled baking dish with aluminum foil, ensuring it doesn’t touch the cheese on top. Place the lasagna in the preheated oven and bake for 25 minutes. After this time, remove the foil and continue baking for another 10-15 minutes, or until the cheese is bubbly and golden. The aromas wafting through your kitchen will be irresistible!
Step 6: Serve
Once baked, remove the Mushroom and Spinach Lasagna from the oven and allow it to cool for about 10 minutes before slicing. This resting time helps the layers set, making it easier to serve. Garnish with fresh basil before serving warm, and enjoy the comforting flavors with family and friends!

Mushroom and Spinach Lasagna Recipe FAQs
What should I look for when selecting mushrooms?
Absolutely! When choosing mushrooms for your Mushroom and Spinach Lasagna, look for firm, plump mushrooms with a smooth, unblemished exterior.

It can be stored for up to 3 months. When you’re ready to eat, thaw in the fridge overnight and reheat in a preheated oven at 350°F (175°C) for about 25-30 minutes until piping hot.
What if my lasagna noodles stick together while cooking?
No worries! To prevent your lasagna noodles from sticking, make sure to stir them occasionally while boiling. Use plenty of salted water, as this helps to keep them separate. If they do stick, you can gently run cold water over them in a colander to separate them. Just be careful not to overcook them, as they should still be al dente for the best texture in your lasagna.
Is this lasagna suitable for vegetarians and gluten-free diets?
Indeed! This Mushroom and Spinach Lasagna is a perfect vegetarian option packed with nutrients. If you need a gluten-free version, simply swap conventional lasagna noodles for gluten-free ones.
