Creamy Mushroom and Spinach Lasagna

#### Instructions:

**1. Prepare the Mushroom and Spinach Filling:**

– **Cook the Mushrooms:** In a large skillet, heat olive oil over medium heat. Add the chopped onion and cook for 3-4 minutes, until softened. Add the garlic and cook for another minute until fragrant.
– **Add the Mushrooms:** Add the sliced mushrooms to the skillet and sauté until they release their moisture and begin to brown, about 8-10 minutes. Stir occasionally to ensure even cooking.
– **Wilt the Spinach:** Add the spinach to the skillet in batches, stirring as you go until the spinach wilts down. Season with salt, pepper, and dried thyme. Remove from heat and let the mixture cool slightly.
– **Mix with Cheese:** Once the mushroom and spinach mixture has cooled, transfer it to a large bowl. Add the ricotta and grated mozzarella, stirring until well combined. Set aside.

**2. Make the Creamy Béchamel Sauce:**

– **Melt the Butter:** In a medium saucepan, melt the butter over medium heat. Once melted, add the flour and cook, whisking constantly, for about 1-2 minutes, until it forms a smooth paste (this is your roux).
– **Add the Milk:** Gradually whisk in the milk, ensuring that there are no lumps. Continue to cook, whisking frequently, until the sauce thickens, about 5-7 minutes.
– **Add Cheese and Seasoning:** Once the sauce has thickened, stir in the grated Parmesan cheese until it melts into the sauce. Season with salt, pepper, and a pinch of nutmeg (if using). Remove from heat and set aside.

**3. Assemble the Lasagna:**

– **Preheat the Oven:** Preheat your oven to 375°F (190°C).
– **Layer the Lasagna:** In a 9×13-inch baking dish, spread a thin layer of the béchamel sauce on the bottom. Layer the no-boil lasagna noodles over the sauce, making sure they don’t overlap. If using regular lasagna noodles, layer them as you normally would, ensuring they are cooked according to package instructions.
– **Add the Mushroom and Spinach Filling:** Spoon half of the mushroom and spinach mixture over the noodles, spreading it out evenly. Add a layer of béchamel sauce on top of the filling, followed by another layer of noodles.
– **Repeat Layers:** Repeat the process, layering noodles, the remaining mushroom-spinach filling, and more béchamel sauce. Finish with a final layer of noodles and the remaining béchamel sauce on top.
– **Top with Cheese:** Sprinkle the top with extra mozzarella cheese for a cheesy, golden finish.

**4. Bake the Lasagna:**

– Cover the lasagna with aluminum foil (to prevent it from drying out) and bake in the preheated oven for 25 minutes.
– After 25 minutes, remove the foil and bake for an additional 10-15 minutes, until the top is golden and bubbly.

**5. Let it Rest and Serve:**

– Remove the lasagna from the oven and let it rest for about 10 minutes before slicing. This helps the layers set and makes it easier to cut.
– Garnish with fresh parsley for a touch of color and serve hot!
