# How to Make It:
01 - Set oven temperature to 375°F.
02 - Heat olive oil in a skillet over medium heat. Add minced garlic and chopped rosemary; sauté for 1 minute until fragrant. Add shredded chicken, salt, and pepper, tossing to combine. Remove from heat.
03 - Melt butter in a saucepan over medium heat. Whisk in flour and cook for 1 minute. Gradually add milk, whisking constantly until sauce thickens, about 5 to 7 minutes. Stir in nutmeg and Parmesan cheese. Remove from heat.
04 - If desired, fold chopped spinach into the chicken mixture.
05 - Spread a thin layer of béchamel sauce in a 9x13-inch baking dish. Arrange 3 no-boil lasagna noodles over the sauce. Top with one-third of the chicken mixture, one-quarter of the béchamel, and one-quarter of the mozzarella. Repeat layering twice more.
06 - Finish with the remaining noodles, béchamel sauce, mozzarella, and Parmesan cheese.
07 - Cover the dish with foil and bake for 30 minutes.
08 - Remove foil and continue baking for 10 to 15 minutes until the top is golden and bubbling.
09 - Allow the dish to rest for 10 minutes before slicing and serving.
