12 oz (340 g) mushrooms, sliced (button, cremini, or mixed)
5 oz (140 g) fresh spinach
Salt and pepper, to taste
½ teaspoon dried thyme or Italian herbs

For the Creamy Sauce (Béchamel):

4 tablespoons butter
¼ cup all-purpose flour
4 cups milk, warmed
¼ teaspoon nutmeg (optional)

½ cup grated Parmesan cheese

For the Lasagna:

9–12 lasagna noodles (no-boil or regular)
2 cups shredded mozzarella cheese
½ cup ricotta cheese (optional, for extra creaminess)

Equipment Needed

Large skillet
Medium saucepan
Whisk
9×13-inch baking dish
Wooden spoon or spatula
Knife and cutting board

Step-by-Step Instructions

1. Prepare the Vegetables

Heat olive oil in a skillet over medium heat. Add onions and sauté until translucent, about 3 minutes. Add garlic and cook another minute.

Add mushrooms, salt, pepper, and thyme. Sauté until mushrooms release their moisture and start to brown, about 5–7 minutes.

Add spinach and cook until wilted. Remove from heat and set aside.

2. Make the Creamy Béchamel Sauce

In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 1–2 minutes to form a roux.

Gradually whisk in warm milk, stirring constantly to avoid lumps. Simmer for 5–7 minutes until thickened. Add nutmeg, salt, pepper, and Parmesan cheese. Remove from heat.

3. Preheat Oven

Preheat your oven to 375°F (190°C).

4. Assemble the Lasagna

Spread a thin layer of béchamel sauce on the bottom of the baking dish.
Lay down a layer of lasagna noodles.
Spread half of the mushroom-spinach mixture over the noodles.
Drizzle a portion of béchamel sauce and sprinkle some mozzarella cheese.
Repeat with another noodle layer, the remaining vegetable mixture, béchamel, and mozzarella.
Top with the final layer of noodles, béchamel, and remaining mozzarella. Add dollops of ricotta if using.

5. Bake

Cover the lasagna with aluminum foil and bake for 25–30 minutes. Remove foil and bake another 10–15 minutes until cheese is golden and bubbly.

6. Rest and Serve

Let the lasagna rest for 10 minutes before slicing. This helps the layers set and makes serving easier.

Garnish with fresh basil or parsley and enjoy!
