How to Make Mushroom Lasagne

This is where the magic happens — a little sautéing, a little stirring, and suddenly your kitchen smells like comfort itself.

Step 1: Sauté the Mushrooms

Heat olive oil and butter in a large skillet over medium heat. When the butter begins to foam, toss in your sliced mushrooms. Don’t overcrowd the pan — give them space to brown rather than steam.
Cook for 8–10 minutes, stirring occasionally, until golden and caramelized. Add minced garlic and thyme, cooking another 30 seconds until fragrant. Pour in the white wine (if using), scraping up any golden bits. Let it simmer until nearly evaporated. Season with salt and pepper.

Step 2: Make the Silky Béchamel Sauce

In a saucepan, melt butter over medium heat. Whisk in flour to form a smooth paste (roux) and cook for 1 minute. Slowly add warm milk, whisking constantly until smooth and thickened — about 5 minutes. Add nutmeg, salt, and pepper to taste.

Step 3: Prep and Layer

Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or oil.

Layer as follows:

1. A thin layer of béchamel (to prevent sticking).
2. Lasagne sheets.
3. Mushroom filling.
4. Dollops of ricotta.
5. Drizzle of béchamel.
6. Sprinkle mozzarella and parmesan.

Repeat until you’re out of ingredients, finishing with béchamel and cheese on top.

Step 4: Bake Until Golden

Cover with foil and bake for 25 minutes. Remove foil and bake another 15–20 minutes, until bubbling and golden.

Step 5: Rest and Serve

Let the lasagne rest 10–15 minutes before slicing. Garnish with parsley or basil for a bright, fresh touch.
