Instructions

Step 1: Prepare the Mushroom and Spinach Filling

  1. Heat olive oil in a large skillet over medium heat.
  2. Add the onion and sauté for 3–4 minutes until softened.
  3. Stir in the garlic and cook for another minute until fragrant.
  4. Add the mushrooms and cook for 6–8 minutes until softened and lightly browned.
  5. Toss in the spinach and cook until wilted. Season with thyme, salt, and pepper. Remove from heat and set aside.

Step 2: Make the Creamy White Sauce

  1. In a medium saucepan, melt the butter over medium heat.
  2. Whisk in the flour and cook for 1–2 minutes to form a roux.
  3. Gradually add the milk, whisking continuously to prevent lumps.
  4. Bring the sauce to a gentle simmer and cook until thickened, about 5 minutes.
  5. Stir in the Parmesan cheese, nutmeg (if using), salt, and pepper. Remove from heat.

Step 3: Assemble the Lasagna

  1. Preheat your oven to 375°F (190°C).
  2. Spread a thin layer of the white sauce at the bottom of a 9×13-inch baking dish.
  3. Layer the ingredients in the following order:
    • 3 lasagna noodles
    • 1/3 of the ricotta cheese
    • 1/3 of the mushroom and spinach mixture
    • 1/3 of the white sauce
    • 1/3 of the mozzarella cheese
  4. Repeat the layers two more times, finishing with the white sauce and topping with Parmesan cheese.

Step 4: Bake

  1. Cover the dish with foil and bake for 25 minutes.
  2. Remove the foil and bake for an additional 15–20 minutes, or until the top is golden and bubbly.

Step 5: Rest and Serve

  1. Let the lasagna cool for 10 minutes before slicing.
  2. Garnish with fresh parsley or basil, if desired, and serve warm.
