# Step-by-Step Guide:

02 - In a skillet over medium heat, warm olive oil. Add garlic and rosemary; sauté for 1 minute until fragrant. Stir in shredded chicken, salt, and pepper; combine well and remove from heat.
03 - Melt butter in a saucepan over medium heat. Whisk in flour and cook for 1 minute. Gradually add milk while whisking constantly until sauce thickens, about 5 to 7 minutes. Season with nutmeg and blend in Parmesan. Remove from heat.
04 - If desired, mix chopped spinach into the chicken mixture.
05 - Spread a thin layer of béchamel sauce in a 9x13-inch baking dish. Arrange 3 lasagna noodles over the sauce.

Top final layer with remaining noodles, béchamel, mozzarella, and Parmesan.
06 - Cover with foil and bake for 30 minutes.
07 - Remove foil and bake for an additional 10 to 15 minutes until golden and bubbling.
