Instructions:

1. Preheat your oven to 375°F (190°C).
2. In a skillet, melt the butter and sauté the garlic until fragrant. Add the sliced mushrooms and cook until tender.
3. Stir in the chopped spinach and cook until it wilts. Remove from heat and set aside.
4. In a separate saucepan, heat the heavy cream and bring it to a simmer. Stir in the ricotta cheese until smooth and creamy. Season with salt and pepper to taste.
5. In a baking dish, begin layering by adding a layer of lasagna noodles, followed by the spinach-mushroom mixture, creamy sauce, and shredded mozzarella. Repeat the layering process, finishing with mozzarella and Parmesan cheese on top.
6. Bake for 30–35 minutes until the lasagna is bubbly and golden. Allow it to cool for a few minutes before serving.
