Step‑by‑Step Instructions for Mushroom And Spinach Lasagna
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C) to ensure it reaches the right temperature for baking your Mushroom and Spinach Lasagna. This step is crucial, as it allows the flavors to meld beautifully while the lasagna cooks. Have a 9×13-inch baking dish ready, greased with a light coating of olive oil or cooking spray for easy removal later.
Step 2: Cook the Noodles
In a large pot, bring salted water to a boil over medium-high heat. Add the lasagna noodles and cook them according to package instructions until they are al dente, which usually takes about 8-10 minutes. Once done, drain the noodles in a colander and rinse them with cold water to stop the cooking process, then set them aside.
Step 3: Sauté the Aromatics
Heat a generous drizzle of olive oil in a large skillet over medium heat. Once the oil warms, add diced onion and sauté until translucent, about 5 minutes. Stir in minced garlic and cook for another minute until fragrant. This mixture will form the flavorful base of your Mushroom and Spinach Lasagna.
Step 4: Cook the Mushrooms
Next, add the sliced mushrooms to the skillet, along with dried thyme, salt, and pepper to taste. Sauté everything together for about 7-10 minutes until the mushrooms are tender and releasing their moisture. This will enhance the earthy flavors in your lasagna, creating a hearty filling that complements the sauce.
Step 5: Add the Spinach
Now it’s time to bring in the greens! Add the chopped spinach to the skillet, cooking it until wilted, roughly 2-3 minutes more. The vibrant color of the spinach will beautifully contrast with the other ingredients, adding nutrition and freshness to your Mushroom and Spinach Lasagna filling.
Step 6: Start Layering
In your greased baking dish, spread a thin layer of marinara sauce at the bottom to prevent sticking. Begin layering by placing three lasagna noodles on top, then spread half of the ricotta cheese over the noodles for a creamy base. Follow this with half of your sautéed mushroom and spinach mixture, sprinkling on mozzarella and Parmesan cheese for extra flavor.
Step 7: Repeat the Layers
Continue building your lasagna by repeating the layers: add another three noodles, the remaining ricotta, the rest of the mushroom and spinach mixture, and a generous handful of shredded mozzarella and Parmesan. Finish off with a final layer of noodles topped with more marinara sauce, ensuring every bite is filled with goodness.
Step 8: Bake the Lasagna
Cover the baking dish with aluminum foil, making sure it doesn’t touch the cheese, and place it in the preheated oven. Bake for 25 minutes, allowing the flavors to meld. After 25 minutes, remove the foil and bake for an additional 10-15 minutes until the cheese is bubbly and golden brown, creating that irresistible melted topping.
Step 9: Cool and Serve
Once baked to perfection, remove the Mushroom and Spinach Lasagna from the oven and let it cool for about 10-15 minutes. This resting time will help the layers set, making slicing easier. Garnish with fresh basil for a vibrant touch before serving, and dive into this hearty vegetarian dish!

Make Ahead Options
These Mushroom and Spinach Lasagna is perfect for meal prep enthusiasts! You can prepare the filling (sautéed mushrooms, spinach, ricotta, and seasonings) up to 24 hours in advance and refrigerate it in an airtight container to maintain freshness. Additionally, you can assemble the entire lasagna up to 3 days prior to baking; just cover it tightly with foil to prevent drying out. When you’re ready to bake, simply preheat the oven to 375°F (190°C) and pop the lasagna in, starting with the covered baking time, and then uncover to let that cheese bubble to golden perfection. This method ensures your lasagna is just as delicious while saving you time during busy weeknights!
How to Store and Freeze Mushroom And Spinach Lasagna
Fridge: Store leftovers in an airtight container for up to 3 days. This delicious lasagna often tastes even better the next day as the flavors meld.
Freezer: To freeze, wrap the cooled lasagna tightly in plastic wrap or aluminum foil, then place it in an airtight container. It can be stored for up to 3 months.
Reheating: Thaw overnight in the fridge before reheating. Bake at 350°F (175°C) for 25-30 minutes until heated through, ensuring the cheese is melty and delicious.
Make-Ahead Tip: Prepare the mushroom and spinach lasagna ahead of time and freeze it unbaked. Simply pop it in the oven when ready for a cozy meal!
