Step‑by‑Step Instructions for Mushroom and Spinach Lasagna
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, lightly grease a 9×13-inch baking dish with olive oil or non-stick spray. This step ensures that your Mushroom and Spinach Lasagna will easily slide out after baking, maintaining its lovely layers.
Step 2: Cook the Lasagna Noodles
In a large pot, bring salted water to a vigorous boil. Add the lasagna noodles and cook them according to the package instructions until al dente, usually about 8-10 minutes. Once cooked, drain the noodles and toss them in a bit of olive oil to prevent sticking, then set them aside to cool slightly.
Step 3: Prepare the Mushroom Filling
Heat a tablespoon of olive oil in a large skillet over medium heat. Add diced onions and sauté for about 5 minutes until they become translucent, followed by minced garlic for an additional minute until fragrant. Stir in the sliced mushrooms, dried thyme, salt, and pepper, cooking until the mushrooms soften—about 5-7 minutes. Finally, add in the fresh spinach, cooking just until wilted, then remove the skillet from heat.
Step 4: Assemble the Lasagna
Spread a thin layer of marinara sauce at the bottom of the greased baking dish. Layer three lasagna noodles on the sauce, then spoon half of the ricotta cheese over the noodles, followed by half of the mushroom filling. Sprinkle one-third of both the mozzarella and Parmesan cheeses. Repeat the layering process, finishing off with remaining noodles, sauce, and the rest of the cheeses on top.
Step 5: Bake the Lasagna
Cover the assembled lasagna with aluminum foil, ensuring it doesn’t touch the cheese. Place it in the preheated oven and bake for 25 minutes. After that, carefully remove the foil and bake for an additional 10-15 minutes. You’ll know it’s ready when the cheese is bubbly and golden brown, creating a deliciously inviting top layer.
Step 6: Cool and Serve
Once baked, remove the Mushroom and Spinach Lasagna from the oven and let it cool for about 5-10 minutes to allow the layers to set. Garnish with fresh basil leaves for a pop of color and flavor, then slice it into generous portions and serve warm. Enjoy this comforting dish with a side salad or some garlic bread!

Mushroom and Spinach Lasagna Recipe FAQs
What type of mushrooms should I use for the Mushroom and Spinach Lasagna?
Absolutely! I recommend using cremini or button mushrooms for their rich flavor and perfect texture. Both of these varieties sauté beautifully and add depth to your filling. If you’re feeling adventurous, shiitake mushrooms can give your lasagna an earthy twist!
How can I store leftover Mushroom and Spinach Lasagna?
Very simply! Store any uneaten lasagna in an airtight container in the fridge for up to 3 days. Just make sure it’s cooled down properly before sealing it up to keep the flavors intact. If you’d like, you can also cover the dish with plastic wrap and aluminum foil for extra protection against drying out.
Can I freeze Mushroom and Spinach Lasagna?
Definitely! For optimal results, assemble the lasagna but do not bake it. Wrap the tray tightly in plastic wrap and aluminum foil to prevent freezer burn, and it will keep well for up to 3 months. When you’re ready to enjoy it, thaw it overnight in the refrigerator before baking to ensure it cooks evenly.
What if my lasagna noodles are sticking together?
Great question! If you find your lasagna noodles are sticking together, it’s important to stir the noodles occasionally while they cook to prevent clumping. After draining, rinse them lightly under cold water to cool them down and create a slippery surface that helps avoid sticking.
Is Mushroom and Spinach Lasagna safe for anyone with dairy allergies?
While this recipe is rich and creamy, it does contain dairy, making it unsuitable for those with lactose intolerance or dairy allergies. However, for a non-dairy alternative, you can substitute traditional cheeses with vegan options, such as cashew cheese or nutritional yeast for added flavor, ensuring everyone can enjoy a slice of lasagna!
How do I ensure my spinach is properly wilted in the filling?
To ensure your spinach is perfectly wilted, simply cook it down with the sautéed mushrooms until it reduces significantly. This usually takes about 2-3 minutes. Make sure to remove any excess moisture before adding it to the lasagna layers, or the dish may turn out watery. Enjoy this comforting vegetarian Mushroom and Spinach Lasagna!
