Creamy Spinach & Mushroom Lasagna Recipe

Ingredients

For the Spinach & Mushroom Filling:

  • 2 tbsp olive oil
  • 1 small onion, diced
  • 3 cloves garlic, minced
  • 12 oz mushrooms, sliced (button, cremini, or portobello)
  • 5 cups fresh spinach (or 10 oz frozen, thawed and drained)
  • 1 tsp dried basil
  • 1 tsp dried oregano
  • Salt & black pepper, to taste

For the Cream Sauce:

  • 4 tbsp butter
  • 4 tbsp all-purpose flour
  • 3 cups whole milk
  • 1 cup heavy cream
  • 1½ cups grated parmesan cheese
  • ½ tsp nutmeg (optional, but adds depth of flavor)
  • Salt & pepper, to taste

For the Lasagna Layers:

  • 9 lasagna noodles, cooked al dente
  • 2 cups ricotta cheese
  • 1 large egg
  • 2 cups shredded mozzarella cheese
  • ½ cup grated parmesan cheese (for topping)

Instructions

Step 1: Prepare the Spinach & Mushroom Filling

  1. Heat olive oil in a large skillet over medium heat.
  2. Sauté the onion until soft, about 3 minutes, then add the garlic and cook for another 30 seconds.
  3. Add the mushrooms, cooking until they release their moisture and become golden brown, about 6-8 minutes.
  4. Stir in the spinach, basil, oregano, salt, and black pepper, cooking until the spinach wilts (or until warmed through if using frozen spinach). Remove from heat and set aside.

Step 2: Make the Creamy Parmesan Sauce

  1. In a saucepan, melt butter over medium heat. Stir in the flour, whisking continuously for 1 minute to form a roux.
  2. Gradually whisk in milk and heavy cream, stirring until smooth and thickened, about 5 minutes.
  3. Remove from heat and stir in parmesan cheese, nutmeg, salt, and black pepper. Mix well until smooth and creamy.

Step 3: Prepare the Ricotta Mixture

  1. In a bowl, mix ricotta cheese with 1 egg, stirring until well combined. This adds structure to the lasagna layers.

Step 4: Assemble the Lasagna

  1. Preheat your oven to 375°F (190°C).
  2. In a greased 9x13-inch baking dish, spread a thin layer of cream sauce.
  3. Layer 3 lasagna noodles, followed by ½ of the ricotta mixture, ½ of the spinach-mushroom filling, ¼ of the mozzarella, and a generous drizzle of cream sauce.
  4. Repeat with another 3 noodles, the remaining ricotta mixture, the rest of the spinach-mushroom filling, more mozzarella, and more cream sauce.
  5. Top with the last 3 noodles, the remaining cream sauce, the rest of the mozzarella cheese, and the parmesan cheese.

Step 5: Bake & Serve

  1. Cover with foil and bake for 30 minutes. Remove foil and bake uncovered for an additional 10-15 minutes, until golden and bubbly.
  2. Let the lasagna rest for 10 minutes before slicing. Garnish with fresh parsley or extra parmesan if desired.
