Instructions:

1. Preheat and Prep: Preheat your oven to 350°F (175°C). Grease a baking dish.
2. Create the Sauce: In a saucepan, melt butter over medium heat. Add minced garlic and cook until fragrant. Stir in flour to create a roux. Gradually whisk in milk until smooth. Cook, stirring constantly, until the sauce thickens. Season with salt, pepper, and nutmeg if using.
3. Layering Magic: In the prepared baking dish, spread a thin layer of the sauce. Place three lasagna noodles on top. Add a portion of shredded chicken, blanched broccoli, and a generous sprinkle of mozzarella and Parmesan cheeses. Repeat layers, finishing with a layer of cheese on top.
4. Bake to Perfection: Cover the baking dish with foil and bake for 25-30 minutes. Remove the foil and bake for an additional 10-15 minutes or until the cheese is golden and bubbly.
5. Garnish and Serve: Let the lasagna rest for a few minutes. Garnish with fresh parsley, slice, and savor the savory harmony of Chicken and Broccoli Lasagna!
