Step‑by‑Step Instructions for Mushroom And Spinach Lasagna
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This crucial step ensures that your Mushroom And Spinach Lasagna bakes evenly, allowing the cheeses to melt perfectly while the flavors meld together. Take a moment to gather your ingredients and equipment, including a 9×13-inch baking dish, to have everything ready for the assembly process.
Step 2: Prepare the Baking Dish
Lightly grease your 9×13-inch baking dish with olive oil or cooking spray, ensuring a non-stick surface for your lasagna. This will help the layers release easily after baking, making for a beautiful presentation. Keep this prepared dish nearby as we start layering the tasty components of your Mushroom And Spinach Lasagna.
Step 3: Cook the Lasagna Noodles
Cook the lasagna noodles in a large pot of salted boiling water, following the package instructions until al dente—typically around 8-10 minutes. Once cooked, drain them and set aside, making sure to arrange them flat to prevent sticking. These noodles will form the delicious and hearty layers of your Mushroom And Spinach Lasagna.
Step 4: Sauté the Aromatics
In a skillet, heat a couple of tablespoons of olive oil over medium heat. Add finely chopped onion and sauté for about 3-4 minutes until translucent and fragrant. Next, add minced garlic, cooking for an additional minute until it releases its aromatic charm. This sautéed base will add an incredible depth of flavor to your Mushroom And Spinach Lasagna.
Step 5: Add the Mushrooms and Spinach
Now, toss in the sliced mushrooms along with dried thyme, salt, and pepper. Cook until the mushrooms are tender and the liquid has evaporated, approximately 5-7 minutes. Stir in the fresh spinach and cook until just wilted, which should take about 2-3 minutes. This mixture is key to the assembled layers of your Mushroom And Spinach Lasagna.
Step 6: Assemble the Lasagna
Start by spreading a thin layer of marinara sauce at the bottom of the greased baking dish. Lay down three cooked lasagna noodles and spoon half of the ricotta cheese over them, spreading it gently. Follow with the mushroom and spinach mixture, then sprinkle a blend of mozzarella and Parmesan cheese on top. This layering technique is essential for creating a rich Mushroom And Spinach Lasagna.
Step 7: Repeat the Layers
Add another layer of marinara sauce, followed by three more noodles. Repeat the layers using the remaining ricotta, the rest of the mushroom mixture, and more mozzarella and Parmesan. Finally, top everything with the last three noodles, cover with the remaining marinara sauce, and finish with a generous sprinkle of Mozzarella and Parmesan.
Step 8: Bake the Lasagna
Cover the assembled Mushroom And Spinach Lasagna with aluminum foil to keep it moist while baking. Place it in the preheated oven and bake for 25 minutes. After that, remove the foil and continue baking for another 10-15 minutes or until the cheese is bubbly and golden brown on top, indicating a deliciously cooked lasagna.
Step 9: Cool and Serve
Once baked, allow your Mushroom And Spinach Lasagna to cool slightly for about 10 minutes. This resting period makes it easier to slice and serves to enhance the flavors. Garnish with fresh basil just before serving, and enjoy the satisfying layers of this comforting dish with family and friends.

Make Ahead Options
These Mushroom and Spinach Lasagna layers are perfect for meal prep! You can assemble the entire lasagna up to 24 hours in advance and store it in the refrigerator, covered tightly with foil to maintain moisture. If you need more time, it can also be frozen for up to 3 months; just be sure to wrap it well to prevent freezer burn. When you’re ready to enjoy this comforting dish, let it thaw in the fridge overnight if frozen, then bake it straight from the refrigerator for about 35-40 minutes at 375°F (190°C). This way, you’ll have a delicious, hearty meal with minimal effort, just as satisfying as when freshly made!

What if my lasagna turns out soggy?
A common concern! If your Mushroom and Spinach Lasagna ends up soggy, it could be due to excess moisture from the marinara sauce or not draining the spinach well enough.

Great question! The Mushroom and Spinach Lasagna is inherently vegetarian, perfect for meatless meals.
