Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the lasagna:
12 lasagna noodles
2 cups ricotta cheese
1 cup shredded Parmesan
2 cups shredded mozzarella
3 cups fresh spinach, wilted
3 cups sliced mushrooms
2 tablespoons olive oil
3 cloves garlic, minced
1/2 teaspoon salt
1/2 teaspoon black pepper
1/4 cup chopped parsley (for garnish)

For the white sauce:
3 tablespoons butter
3 tablespoons flour
3 cups milk
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
Salt and pepper to taste

Directions

1. Preheat the oven to 375°F (190°C).
2. Cook the lasagna noodles according to package directions. Drain and set aside.
3. Heat olive oil in a pan over medium heat. Sauté the sliced mushrooms for about 5 minutes, until softened. Add the minced garlic and cook for another minute.
4. Add the fresh spinach and stir until wilted. Season with salt and pepper, then set aside.
5. Prepare the white sauce by melting butter in a saucepan over medium heat. Whisk in the flour and cook for 1–2 minutes until lightly golden.
6. Slowly pour in the milk, whisking continuously until the sauce thickens. Add garlic powder, onion powder, salt, and pepper.
7. In a bowl, combine ricotta and Parmesan until smooth.
8. Begin assembling the lasagna by spreading a thin layer of white sauce at the bottom of a baking dish.
9. Add a layer of lasagna noodles, followed by the ricotta mixture, the mushroom–spinach mixture, mozzarella, and more white sauce. Repeat the layering process until all ingredients are used.
10. Finish with a final layer of mozzarella on top.
11. Bake uncovered for 30–35 minutes, or until the cheese is bubbly, golden, and slightly crispy at the edges.
12. Allow the lasagna to rest for 10 minutes before slicing. Garnish with chopped parsley.
