Ingredients

Units Scale

For the Vegetables:

  • 2 tbsp olive oil
  • 2 cups mushrooms, sliced
  • 4 cups fresh spinach
  • 3 cloves garlic, minced
  • Salt and pepper, to taste

For the White Sauce:

  • 4 tbsp unsalted butter
  • 4 tbsp all-purpose flour
  • 3 cups milk
  • 1 cup heavy cream
  • 1/4 tsp nutmeg (optional)
  • Salt and pepper, to taste

For the Lasagna:

  • 9 lasagna noodles, cooked
  • 2 cups ricotta cheese
  • 2 cups shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 1 tsp dried Italian seasoning

Instructions

  1. Prepare the Vegetables:
    1. Heat olive oil in a large skillet over medium heat.
    2. Add mushrooms and cook until softened, about 5 minutes.
    3. Add garlic and spinach, cooking until spinach wilts. Season with salt and pepper. Set aside.
  2. Make the White Sauce:
    1. In a saucepan, melt butter over medium heat.
    2. Whisk in flour and cook for 1 minute.
    3. Gradually pour in milk and cream, whisking constantly to avoid lumps.
    4. Cook until thickened, about 5 minutes. Season with nutmeg (if using), salt, and pepper.
  3. Assemble the Lasagna:
    1. Preheat oven to 375°F (190°C).
    2. Spread a thin layer of white sauce on the bottom of a 9×13-inch baking dish.
    3. Layer 3 lasagna noodles, followed by a portion of the vegetable mixture, dollops of ricotta, mozzarella, Parmesan, and white sauce. Repeat layers twice.
    4. Finish with a final layer of noodles, white sauce, and remaining cheeses.
  4. Bake:
    1. Cover with foil and bake for 30 minutes.
    2. Remove foil and bake for an additional 10–15 minutes, until golden and bubbly.
  5. Serve:
    1. Let the lasagna rest for 10 minutes before slicing. Enjoy!

Notes

  • For added flavor, sauté the mushrooms with a splash of white wine.
  • You can use no-boil lasagna noodles to save time.
  • Feel free to substitute spinach with kale or add more vegetables like zucchini or bell peppers.
