Directions 

Prep Spinach & Mushrooms: Heat olive oil in a large skillet over medium heat. Add garlic and sauté for 1 minute. Add mushrooms and cook until soft, about 5-6 minutes. Add spinach and cook until wilted. Season with salt and pepper. Set aside.
Layer Lasagna: In a greased 9×13 baking dish, spread a thin layer of Alfredo sauce. Add 3 lasagna noodles. Top with some spinach-mushroom mixture, ricotta, mozzarella, and Parmesan. Repeat layers until ingredients are used, finishing with a layer of Alfredo sauce and mozzarella.
Bake: Preheat oven to 375°F (190°C). Cover the lasagna with foil and bake for 25 minutes. Uncover and bake for another 10-15 minutes until bubbly and golden.
Serve: Let the lasagna cool for 5 minutes before slicing. Garnish with fresh parsley and enjoy!
