Mushroom Lasagna Ingredients
For the Mushroom Filling
• Olive Oil – Adds richness and helps sauté vegetables; substitute with vegetable oil for a neutral flavor.
• Chopped Onions – Provide a savory base flavor; yellow or white onions work well.
• Minced Garlic – Enhances aroma and depth of flavor; fresh garlic is preferred for the best taste.
• Sliced Mushrooms (cremini, shiitake, portobello) – The main filling ingredient, offering earthy flavor; exchange for button or oyster mushrooms if desired.
• Dried Thyme & Oregano – Add herbal notes; fresh herbs can be substituted, reducing quantity by around one-third.
• Salt & Pepper – Basic seasonings for balancing flavors; adjust to taste.
• White Wine (optional) – Intensifies the flavor of the mushroom mixture; omit if avoiding alcohol or substitute with vegetable broth.
• Grape Tomatoes – Provide sweetness and acidity, important for contrast; can use cherry tomatoes as a substitute.
• Chopped Spinach – Incorporates greens for added nutrition and flavor; substitute with other greens like kale.
For the Creamy Bechamel Sauce
• Butter – Used in making Bechamel sauce, contributes to the creamy texture; substitute with margarine for a vegan twist.
• Flour – Thickens the Bechamel sauce; use gluten-free flour for a gluten-free version.
• Warmed Milk – Creates the sauce base; any non-dairy milk can be used for a vegan option.
• Nutmeg – Adds warmth and depth to the Bechamel sauce; optional but enhances flavor.
For Assembling the Lasagna
• Lasagna Noodles – Provide the structure of the dish; use gluten-free noodles for dietary needs.
• Mozzarella and Parmesan Cheese – Offer creaminess and flavor; vegan cheese can be used for a dairy-free version.
Step‑by‑Step Instructions for Mushroom Lasagna
Step 1: Sauté the Vegetables
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the chopped onions and sauté until they become translucent, about 5 minutes. Stir in the minced garlic and cook for an additional minute, until fragrant. This base will add depth of flavor to your Mushroom Lasagna.
Step 2: Cook the Mushrooms
Now, add the sliced mushrooms to the skillet. Cook for 8 to 10 minutes, stirring occasionally, until the mushrooms have released their moisture and are nicely browned. Sprinkle in the dried thyme, oregano, salt, and pepper as they cook, ensuring the mushrooms are well-seasoned for the filling.
Step 3: Add Tomatoes and Wine
If you’re using white wine, pour it into the mushroom mixture now, allowing it to evaporate for 2 to 3 minutes. Next, toss in the grape tomatoes, cooking for another 2 to 3 minutes until they soften. Set the mushroom mixture aside; this will be a hearty layer in your Mushroom Lasagna.
Step 4: Make the Bechamel Sauce
In a medium saucepan over medium heat, melt 4 tablespoons of butter. Once melted, whisk in 4 tablespoons of flour, cooking until golden for 2 to 3 minutes. Gradually whisk in 2 cups of warmed milk, stirring continuously until the sauce thickens, about 5 to 7 minutes. Season with a pinch of nutmeg, salt, and pepper for a creamy finish.
Step 5: Prepare the Noodles
Preheat your oven to 375°F (190°C). While the oven is warming up, cook the lasagna noodles according to package instructions until al dente. Drain the noodles and set them aside, ready to form the layers of your Mushroom Lasagna.
Step 6: Assemble the Lasagna
In a large baking dish, start layering your Mushroom Lasagna. Begin with a layer of Bechamel sauce, followed by a layer of lasagna noodles, then add the mushroom mixture and chopped spinach. Repeat this layering process, finishing with a generous layer of Bechamel sauce and a blend of mozzarella and parmesan cheese on top.
Step 7: Bake the Lasagna
Cover your baking dish with aluminum foil and bake the lasagna in the preheated oven for 25 minutes. After that, remove the foil and continue baking for an additional 20 minutes, or until the top is golden and bubbling. The layering will meld together into a comforting slice of Mushroom Lasagna.
Step 8: Rest and Serve
Once baked to perfection, remove the Mushroom Lasagna from the oven and let it rest for about 10 minutes. This resting time will allow the layers to set, making it easier to serve. Garnish with fresh basil before slicing into this creamy delight!

Mushroom Lasagna Recipe FAQs
What type of mushrooms should I use for my Mushroom Lasagna?
Absolutely! For a hearty Mushroom Lasagna, I recommend using cremini, shiitake, or portobello mushrooms, as they provide rich, earthy flavors. If you prefer a milder taste, you can also swap them for white button or oyster mushrooms.
How should I store leftover Mushroom Lasagna?
Very good question! Allow your Mushroom Lasagna to cool completely before covering it with plastic wrap or transferring it to an airtight container. It can be stored in the fridge for up to 4 days. When you’re ready to enjoy, simply reheat it in a preheated oven or microwave until heated through.
Can I freeze Mushroom Lasagna, and if so, how?
Yes, you can definitely freeze Mushroom Lasagna! Wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn, or place it in a freezer-safe container. It should keep well for up to 3 months. When you’re ready to enjoy, thaw it overnight in the fridge and bake in a preheated oven at 350°F (175°C) for about 25-30 minutes.
What can I do if my lasagna turns out watery?
Don’t worry, it happens! To prevent a watery Mushroom Lasagna, ensure that the mushrooms are well-cooked and have released their moisture before adding them to the layers. Also, avoid over-saturating the lasagna with the Bechamel sauce. If it still ends up watery, letting it rest for an extra 10 minutes after baking can help absorb some of the excess liquid.
Are there any dietary considerations I need to keep in mind for Mushroom Lasagna?
Great point! If you’re making this Mushroom Lasagna for someone with dietary restrictions, be sure to use gluten-free noodles and flour if needed. For a dairy-free option, you can substitute the butter and dairy cheeses with margarine and vegan cheese alternatives, respectively. Just check those ingredient labels to avoid any allergens!
