Step-by-Step Instructions
1. Prepare the Mushroom Filling
- Warm the olive oil and butter in a large skillet over medium heat.
- Add the chopped onion and cook for 3-4 minutes until softened.
- Stir in the minced garlic and cook for another minute until fragrant.
- Add the mushrooms, thyme, oregano, salt, and pepper. Cook for 8-10 minutes, stirring occasionally, until the mushrooms release their moisture and become tender.
- Pour in the white wine (or broth) and cook for another 2-3 minutes until the liquid is mostly absorbed. Remove from heat and set aside.
2. Make the Béchamel Sauce
- Begin by melting butter in a medium saucepan over medium heat, stirring occasionally until fully melted.
- Whisk in the flour and cook for 1-2 minutes to create a roux.
- Slowly whisk in the milk, making sure no lumps form. Cook for 5-7 minutes, stirring continuously, until the sauce reaches a thickened consistency.
- Stir in the nutmeg, salt, and pepper. Remove from heat and set aside.
3. Assemble the Lasagna
- Preheat your oven to 375°F (190°C).
- Spread a thin layer of béchamel sauce on the bottom of a 9×13-inch baking dish.
- Place a layer of lasagna noodles over the sauce.
- Spread a third of the mushroom filling over the noodles, followed by a third of the béchamel sauce. Sprinkle with a portion of mozzarella and Parmesan cheese.
- Repeat the layers: noodles, mushrooms, béchamel, and cheese, until all ingredients are used, ending with a layer of cheese on top.
4. Bake the Lasagna
- Cover the baking dish with aluminum foil and bake for 25 minutes.
- Remove the foil and bake for another 15-20 minutes until the top is golden and bubbly.
- Let the lasagna rest for 10 minutes before slicing. This step ensures the layers firm up, making serving cleaner and easier.
5. Garnish and Serve
- Sprinkle with fresh parsley or basil for a pop of color and freshness.
- Serve warm and enjoy!
Tips for Success
- Use a Variety of Mushrooms: Mixing different types of mushrooms adds depth and complexity to the flavor. Try cremini for earthiness, shiitake for a meaty texture, and button mushrooms for a mild, classic taste.
- Don’t Overcook the Noodles: If using traditional lasagna noodles, cook them al dente to prevent them from becoming mushy during baking. If using no-boil noodles, ensure there’s enough sauce to keep them moist.
- Prepare Ahead: Assemble the lasagna up to a day ahead and store it in the fridge. Bake it when you’re ready to serve. This is a great time-saver for busy weeknights or entertaining.
- Freeze for Later: This lasagna freezes well. Wrap tightly and freeze for 3 months; thaw in the fridge before baking. Thaw in the fridge before baking.
- Let It Rest: Allowing the lasagna to rest for 10 minutes after baking helps the layers set, making it easier to slice and serve.

Creative Variations
- Add Spinach: Stir in a handful of fresh spinach with the mushrooms for extra nutrition and a pop of color.
- Go Vegan: Use plant-based butter, milk, and cheese to make this dish vegan-friendly. Nutritional yeast can also provide a cheesy taste without any dairy.
- Add Truffle Oil: Drizzle a bit of truffle oil over the finished lasagna for a luxurious touch. Truffle oil pairs beautifully with mushrooms.
- Spice It Up: Add a pinch of red pepper flakes to the mushroom filling for a subtle kick.
- Incorporate Other Vegetables: Add roasted red peppers, zucchini, or caramelized onions for additional flavor and texture.
- Use Different Cheeses: Experiment with fontina, Gruyère, or ricotta for a unique twist on the classic cheese layers.
Frequently Asked Questions
Can I use no-boil lasagna noodles?
Yes, no-boil noodles work perfectly in this recipe. Just make sure there’s enough sauce to keep them moist while baking. If you’re using traditional noodles, cook them al dente to avoid a mushy texture.
What’s the best way to reheat leftovers?
Reheat single portions in the microwave or the whole dish in the oven at 350°F (175°C) until heated through. Cover with foil to avoid over-browning the top.
Can I use store-bought béchamel sauce?
While homemade béchamel is recommended for the best flavor, you can use a high-quality store-bought version if you’re short on time. Look for one with simple ingredients for the best results.
How can I avoid the lasagna from becoming too watery?
Make sure to cook the mushrooms until most of their moisture has evaporated, and let the lasagna rest before slicing to allow the layers to set. Using no-boil noodles can also help absorb excess liquid.
Can I make this gluten-free?
Yes! Opt for gluten-free lasagna noodles and a gluten-free flour blend for the béchamel sauce. Ensure all other ingredients are also gluten-free.
