03 - 2 cloves garlic, minced
04 - 1 tablespoon olive oil
05 - 1 teaspoon salt
06 - 1/2 teaspoon black pepper
→ Sauce

# Preparation Steps:
01 - Preheat the oven to 375°F.
02 - Heat olive oil in a skillet over medium heat. Add garlic and rosemary; sauté for 1 minute until fragrant. Stir in shredded chicken, salt, and pepper; combine well and remove from heat.
03 - In a saucepan over medium heat, melt butter. Whisk in flour and cook for 1 minute. Gradually add milk while whisking continuously until sauce thickens, about 5 to 7 minutes. Season with nutmeg and stir in Parmesan cheese; remove from heat.
04 - If using, fold chopped spinach into the chicken mixture.
05 - Spread a thin layer of béchamel sauce in a 9x13-inch baking dish. Layer 3 lasagna noodles over the sauce. Add one-third of the chicken mixture, one-quarter of béchamel, and one-quarter of mozzarella. Repeat layers two more times.
06 - Finish by layering the final noodles, remaining béchamel, mozzarella, and Parmesan cheese.
07 - Cover with foil and bake for 30 minutes. Remove foil and bake an additional 10 to 15 minutes until golden and bubbling.
08 - Allow the dish to rest for 10 minutes before slicing and serving.
