Ingredients

Scale

For the Lasagna:

  • 12 lasagna noodles, cooked and drained
  • 2 tablespoons olive oil
  • 2 cups fresh mushrooms, sliced
  • 4 cups fresh spinach, roughly chopped
  • 1 onion, diced
  • 2 cloves garlic, minced
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoon dried basil
  • 1/4 teaspoon red pepper flakes (optional)
  • 1/4 cup vegetable broth (or white wine)
  • Salt and pepper to taste

For the Creamy Béchamel Sauce:

  • 4 tablespoons unsalted butter
  • 4 tablespoons all-purpose flour
  • 3 cups whole milk (or plant-based milk for dairy-free)
  • 1/2 cup grated Parmesan cheese
  • Salt and pepper to taste
  • Pinch of nutmeg (optional)

For the Ricotta Layer:

  • 15 ounces ricotta cheese
  • 1 egg
  • 1/4 cup fresh basil, chopped (optional)
  • 1/2 cup shredded mozzarella cheese (for the ricotta layer)

For the Top Layer:

  • 1 1/2 cups shredded mozzarella cheese
  • 1/4 cup grated Parmesan cheese

Instructions

  1. Prepare the filling:
    • In a large skillet, heat the olive oil over medium heat.
    • Add the sliced mushrooms and cook for 5-7 minutes, stirring occasionally, until they release their moisture and become tender.
    • Add the diced onion, garlic, oregano, basil, and red pepper flakes (if using) to the skillet. Cook for another 3-4 minutes, until the onion softens.
    • Stir in the spinach and cook until wilted, about 2-3 minutes.
    • Add vegetable broth (or white wine) and cook for another 2-3 minutes, until the liquid evaporates. Season with salt and pepper to taste. Remove from heat and set aside.
  2. Make the béchamel sauce:
    • In a medium saucepan, melt the butter over medium heat.
    • Whisk in the flour and cook for about 1 minute, until it forms a paste (roux).
    • Gradually add the milk, whisking continuously to prevent lumps.
    • Continue to cook, whisking constantly, until the sauce thickens, about 5-7 minutes.
    • Stir in the Parmesan cheese, salt, pepper, and a pinch of nutmeg (if using). Remove from heat.
  3. Prepare the ricotta mixture:
    • In a bowl, combine the ricotta cheese, egg, fresh basil (if using), and shredded mozzarella cheese. Stir until well combined.
  4. Assemble the lasagna:
    • Preheat the oven to 375°F (190°C).
    • In a 9×13-inch baking dish, spread a thin layer of béchamel sauce at the bottom.
    • Add a layer of lasagna noodles on top of the sauce.
    • Spread half of the ricotta mixture over the noodles, followed by half of the spinach and mushroom mixture.
    • Pour half of the remaining béchamel sauce over the top.
    • Repeat the layers: noodles, ricotta mixture, spinach and mushroom mixture, and béchamel sauce.
    • Top with the remaining mozzarella and Parmesan cheese.
  5. Bake the lasagna:
    • Cover the lasagna with aluminum foil and bake for 25 minutes.
    • Remove the foil and bake for an additional 10-15 minutes, or until the cheese is golden and bubbly.
    • Let the lasagna sit for 10 minutes before slicing and serving.
  6. Serve and enjoy:
    • Garnish with additional fresh basil or parsley if desired. Serve hot and enjoy!

Notes

  • You can make the béchamel sauce in advance and store it in the fridge for up to 2 days.
  • If you prefer a dairy-free version, use dairy-free ricotta, plant-based milk, and dairy-free cheese.
  • For extra protein, you can add tofu or tempeh to the mushroom and spinach mixture.
