This Mushroom and Spinach Lasagna Recipe is set for deliciousness! Now, let’s gather these ingredients and transform them into a creamy masterpiece.
Step‑by‑Step Instructions for Mushroom And Spinach Lasagna Recipe
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C) while you prepare the baking dish. Grease a 9×13-inch baking dish with olive oil to ensure the lasagna doesn’t stick during baking. This step will help achieve a beautifully melted cheese layer on top of your Mushroom And Spinach Lasagna.
Step 2: Cook the Lasagna Noodles
Boil a large pot of salted water, then carefully add the lasagna noodles. Cook them until they are al dente, about 8-10 minutes, stirring occasionally to prevent sticking. Once cooked, drain the noodles and set them aside on a clean kitchen towel to cool slightly while you prepare the filling.
Step 3: Sauté the Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the chopped onion and sauté for 3-4 minutes until translucent. Stir in minced garlic and let it cook for another minute until fragrant. This will create a flavorful base for your Mushroom And Spinach Lasagna.
Step 4: Cook the Mushrooms and Spinach
Next, incorporate sliced mushrooms, dried thyme, salt, and pepper into the skillet. Cook until the mushrooms soften and any excess liquid evaporates, about 5-7 minutes. Stir in the spinach and cook until wilted, which should take 2-3 minutes. This filling is where the heart of your lasagna comes together!
Step 5: Prepare the Cheese Mixture
In a medium bowl, combine the ricotta cheese, salt, and pepper. Mix until smooth, ensuring the ricotta is well seasoned. This mixture will add a creamy layer between the noodles and the savory mushroom filling in your Mushroom And Spinach Lasagna, contributing to its delightful texture.
Step 6: Start Layering the Lasagna
In your greased baking dish, start by spreading a thin layer of marinara sauce on the bottom. Place three lasagna noodles on top, followed by dollops of the ricotta cheese mixture, a generous portion of the mushroom and spinach filling, and a sprinkle of mozzarella and Parmesan. Repeat these layers until ingredients are used up, finishing with marinara sauce and a final layer of mozzarella.
Step 7: Bake the Lasagna
Cover the assembled Mushroom And Spinach Lasagna with aluminum foil, making sure it is tented slightly so it doesn’t touch the cheese. Bake in the preheated oven for 25 minutes. After this time, remove the foil and bake for an additional 10-15 minutes, until the cheese is bubbly and golden brown on top.
Step 8: Cool and Serve
Once baked to perfection, remove the lasagna from the oven and allow it to cool for about 10 minutes. This cooling step helps the lasagna set, making it easier to slice. Garnish with fresh basil leaves before serving, and enjoy this comforting dish with friends and family!

Mushroom and Spinach Lasagna Recipe FAQs
How do I choose the right mushrooms?
Absolutely! For your Mushroom and Spinach Lasagna, you can use any variety of mushrooms, but button or cremini mushrooms are highly recommended due to their earthy flavor. Look for mushrooms that are firm, plump, and free from dark spots or blemishes. If you find that your mushrooms have dark spots all over, it might be an indication of decay—what a bummer!
How should I store leftover lasagna?
Very easy! Store any leftover Mushroom and Spinach Lasagna in an airtight container in the fridge for up to 3 days. Just make sure it cools completely before sealing it up to preserve the texture and flavor. When you’re ready to dig in again, simply reheat it in the oven or microwave!
Can I freeze Mushroom and Spinach Lasagna?
Absolutely! You can freeze your Mushroom and Spinach Lasagna for up to 3 months, which is a fantastic way to have a homemade meal ready to go.

What if my lasagna turns out watery?
Don’t worry; it’s a common concern! To avoid a watery lasagna, avoid over-saucing. You want just enough marinara to keep the lasagna moist but not drenched. Additionally, ensure that your mushrooms are thoroughly cooked to evaporate any excess moisture before mixing them into the filling. If your lasagna does end up watery, try baking it a bit longer uncovered to help it thicken up.
Are there any allergies I should be aware of?
Definitely! This Mushroom and Spinach Lasagna contains dairy products, so it’s not suitable for those with lactose intolerance or dairy allergies. If you or your guests are avoiding dairy, consider substituting the ricotta and mozzarella with dairy-free alternatives. Always double-check ingredient labels to avoid cross-contamination if allergies are a concern.
Can I customize the ingredients?
Very much so! This recipe is versatile, and you can definitely mix it up to suit your taste. Feel free to add more veggies like zucchini or roasted bell peppers, or even use different cheeses for a unique flavor profile.
