Ingredients

• Lasagna Layers:
  • 12 no-boil lasagna noodles
  • 3 cups fresh spinach, roughly chopped
  • 3 cups mixed mushrooms (cremini, shiitake, or button),sliced
• Creamy White Sauce (Béchamel):
  • 4 tbsp unsalted butter
  • 1/3 cup all-purpose flour, sifted
  • 4 cups whole milk, warmed
  • 1/2 tsp fresh nutmeg, grated
  • Salt and freshly ground black pepper, to taste
  • 3/4 cup freshly grated Parmesan cheese
• Extras:
  • 2 garlic cloves, minced
  • 1 small yellow onion, finely diced
  • 2 tbsp olive oil
  • Fresh basil leaves for garnish
  • Additional Parmesan for topping

Instructions

1. Prepare the sautéed mushroom and spinach filling: Heat olive oil in a large skillet over medium heat. add minced garlic and diced onion; sauté until translucent, about 3 minutes. Toss in the mushrooms and cook until golden and their moisture evaporates, about 7 minutes, stirring occasionally. Add spinach last and cook until just wilted, about 2 minutes. Season with salt and pepper, then set aside.
2. Craft the creamy white sauce: In a heavy-bottomed saucepan, melt the butter over medium heat. Whisk in the sifted flour continuously, cooking the roux until it becomes a soft golden hue, about 2 minutes (avoid browning). gradually whisk in warm milk to prevent lumps, then continue stirring until the sauce thickens smoothly, about 6-8 minutes. Season with salt, pepper, and nutmeg. Remove from heat and stir in Parmesan cheese until melted and silky.
3. Preheat your oven to 375°F (190°C).
4. Assemble your lasagna layers: In a greased 9×13 inch baking dish, spread a thin layer of the creamy white sauce. Place a layer of 4 lasagna noodles to cover the base. Spoon a generous portion of the mushroom-spinach filling evenly over noodles. Ladle white sauce evenly atop the filling layer, smoothing with a spatula. Repeat layering noodles, mushroom-spinach mixture, and white sauce two more times, finishing with a thick final layer of white sauce. sprinkle additional Parmesan cheese on top for a golden crust.
5. Bake: Cover the dish with aluminum foil and bake for 30 minutes to let all flavors meld beautifully. Remove the foil and bake an additional 10-15 minutes to achieve a bubbly, golden top.
6. Rest and serve: Let the lasagna rest for 10 minutes before slicing to allow layers to set perfectly. Garnish with fresh basil leaves for a burst of color and aroma.

Tips for Success

• Choice of mushrooms: Mixing cremini and shiitake adds depth while maintaining a pleasant texture.
• White sauce consistency: Whisk constantly when adding milk and cooking the sauce to prevent lumps and ensure a smooth finish.
• Make-ahead: this lasagna can be fully assembled a day before baking. Just cover tightly and refrigerate until ready to cook.
• Spinach prep tip: Use fresh, not frozen spinach for vibrant color and texture. If using frozen, thaw and squeeze out excess water to avoid a watery layer.
• For a gluten-free option: Substitute traditional noodles with certified gluten-free lasagna sheets and use gluten-free flour for the béchamel.

Layering Tips for a Balanced and Wholesome Dish

To keep every bite flavorful and well-balanced, ensure that neither the mushroom-spinach filling nor the white sauce overwhelms the layers. Spread sauces evenly, and don’t skimp on the fresh ingredients to create a moist yet structured texture. This technique guarantees an inviting contrast of creamy, earthy, and fresh notes.

Serving Suggestions

Serve warm on rustic ceramic plates to emphasize the dish’s homestyle charm. Pair with a crisp green salad tossed in lemon vinaigrette for a refreshing counterbalance. Garnish with fresh basil leaves and a light dusting of Parmesan for an aromatic finish. Crusty garlic bread on the side complements the creamy richness perfectly.
