Servings

Ingredients
For the Lasagna:
- 12 lasagna noodles (oven-ready or boiled according to package instructions)
- 3 cups fresh spinach (chopped)
- 2 cups mushrooms, sliced
- 2 tablespoons olive oil
- 1 small onion, finely chopped
- 3 cloves garlic, minced
For the White Sauce:
- 4 tablespoons unsalted butter
- 4 tablespoons all-purpose flour
- 4 cups milk (whole milk preferred for creaminess)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon nutmeg (optional but recommended)
For Assembly:
- 2 cups shredded mozzarella cheese
- 1 cup grated Parmesan cheese
- 1 cup ricotta cheese (optional, for extra creaminess)
Instructions
Step 1: Prepare the Vegetables
- Heat olive oil in a large skillet over medium heat. Add the chopped onion and cook for 3–4 minutes , or until softened.
- Stir in the minced garlic and cook for another minute until fragrant.
- Add the sliced mushrooms and cook for 5–7 minutes , or until they release their moisture and become tender.
- Add the chopped spinach to the skillet and cook until wilted, about 2–3 minutes . Remove from heat and set aside.
Step 2: Make the White Sauce
- In a medium saucepan, melt the butter over medium heat.
- Whisk in the flour and cook for 1–2 minutes to make a roux, stirring constantly to avoid burning.
- Gradually whisk in the milk, ensuring there are no lumps. Continue whisking until the sauce thickens, about 5–7 minutes .
- Season the sauce with salt, black pepper, and nutmeg (if using). Remove from heat and set aside.
Step 3: Assemble the Lasagna
- Preheat your oven to 375°F (190°C) . Lightly grease a 9×13-inch baking dish.
- Spread a thin layer of white sauce on the bottom of the dish to prevent sticking.
- Place a layer of lasagna noodles over the sauce. Top with half of the spinach-mushroom mixture, a sprinkle of mozzarella, Parmesan, and a drizzle of white sauce.
- Repeat the layers: noodles, remaining spinach-mushroom mixture, cheeses, and white sauce.
- Add a final layer of noodles and cover generously with the remaining white sauce. Sprinkle the top with mozzarella and Parmesan cheese for a golden, bubbly finish.
Step 4: Bake the Lasagna
- Cover the baking dish with aluminum foil and bake for 25 minutes .
- Remove the foil and bake for an additional 15–20 minutes , or until the top is golden brown and the lasagna is bubbling.
Step 5: Rest and Serve
- Let the lasagna rest for 10 minutes before slicing. This helps it set and makes serving easier.
- Garnish with fresh parsley or additional Parmesan cheese if desired. Serve warm and enjoy!
Pro Tips
- Ricotta Option: For extra creaminess, dollop spoonfuls of ricotta cheese between the layers.
- Make Ahead: Assemble the lasagna up to a day in advance, cover, and refrigerate. Bake as directed, adding 5–10 minutes to the cooking time if starting cold.
- Freezer-Friendly: Wrap the unbaked lasagna tightly in plastic wrap and foil, then freeze for up to 3 months . Thaw overnight in the refrigerator before baking.
- Add Protein: For a non-vegetarian version, add cooked Italian sausage or shredded chicken to the layers.
