For the Mushroom Filling
- Olive Oil – Ideal for sautéing vegetables and enhancing flavor; substitute with avocado oil for a higher smoke point.
- Onions – Adds a sweet, aromatic profile; swap shallots in for a milder taste.

For the Bechamel Sauce

Step‑by‑Step Instructions for Mushroom Lasagna
Step 1: Sauté the Aromatics
Start by heating 2 tablespoons of olive oil in a large skillet over medium heat. Add chopped onions and sauté until they become translucent, about 5 minutes. Stir in 3 minced garlic cloves and cook for an additional minute, allowing their wonderful aroma to fill your kitchen. This will create a flavorful base for your Mushroom Lasagna.
Step 2: Cook the Mushrooms
Next, add 8 ounces of sliced mushrooms to the skillet. Cook them for 8 to 10 minutes, stirring occasionally, until they release their moisture and turn golden brown. You’ll notice the mushrooms becoming tender and slightly caramelized, which enhances their earthy flavors, making your Mushroom Lasagna irresistible.
Step 3: Season the Filling
Once the mushrooms are nicely browned, season them with 1 teaspoon of dried thyme, 1 teaspoon of dried oregano, and salt and pepper to taste. If you choose, pour in ½ cup of white wine to deglaze the pan and let it simmer for 2-3 minutes until evaporated. This adds depth to your filling before you incorporate the tomatoes.
Step 4: Add Tomatoes and Spinach
Stir in 2 cups of halved grape tomatoes and cook for an additional 2-3 minutes until they soften and release their juices. To enhance the filling’s texture and nutrition, fold in 2 cups of fresh spinach until wilted. Set this delicious mushroom and tomato mixture aside as you prepare the Bechamel sauce for your Mushroom Lasagna.
Step 5: Create the Bechamel Sauce
In a medium saucepan over medium heat, melt 4 tablespoons of butter. Whisk in ¼ cup of all-purpose flour, cooking until it turns golden, about 2-3 minutes. Gradually pour in 2 cups of warmed milk, whisking continuously until the mixture thickens, about 5-7 minutes. Add a pinch of nutmeg, salt, and pepper to season. This creamy sauce will add richness to your Mushroom Lasagna.
Step 6: Prepare the Lasagna Noodles
Preheat your oven to 375°F (190°C). Meanwhile, cook 9 lasagna noodles according to package instructions, ensuring they are al dente. Once cooked, drain and lay them flat on a clean surface to prevent sticking, ready for layering in your Mushroom Lasagna.
Step 7: Layer the Ingredients
In a baking dish, spread a thin layer of the Bechamel sauce on the bottom. Begin layering with 3 lasagna noodles, followed by half of the mushroom and tomato mixture, a layer of Bechamel sauce, and a sprinkle of mozzarella and Parmesan cheese. Repeat this process, finishing with noodles topped with the remaining Bechamel and cheeses.
Step 8: Bake the Lasagna
Cover the baking dish with foil, ensuring it doesn’t touch the cheese, and bake in the preheated oven for 25 minutes. After that, remove the foil and bake for an additional 20 minutes, or until the top is bubbly and golden brown. Let your gorgeous Mushroom Lasagna rest for about 10 minutes before slicing and serving, allowing the layers to settle beautifully.

Expert Tips for Mushroom Lasagna
-
Rest Before Slicing: Allow the lasagna to sit for about 10 minutes after baking. This helps it hold its shape and makes serving easier.
-
Layer Wisely: Always use at least three layers of noodles to maintain the structure of your Mushroom Lasagna. Uneven layers can cause it to collapse while serving.
-
Avoid Excess Moisture: Ensure mushrooms are fully cooked and released moisture before adding them to the lasagna to prevent sogginess.
-
Adjust Seasoning: Taste each layer as you go, especially the Bechamel sauce. Balancing the salt and spices will elevate the overall flavor of your lasagna.
-
Experiment with Cheese: Try different cheeses or plant-based options to suit your dietary needs while still enjoying a creamy finish to your Mushroom Lasagna.
-
Make Ahead: Prepare the lasagna a day in advance, refrigerate, and bake when ready. Just add a few extra minutes to cooking time if starting from cold.
