Preheat your oven to 375°F (190°C). Grease a 22 x 30 cm baking dish.
Cook the lasagna noodles according to package instructions. Drain and set aside.
In a medium saucepan, melt the butter over medium heat. Add the minced garlic and cook until fragrant, about 1 minute.
Stir in the flour and cook for another minute, until slightly browned.
Gradually whisk in the milk, stirring constantly to prevent lumps. Bring to a simmer and cook until the sauce has thickened, about 5-7 minutes.
Add the dried basil, dried oregano, salt, and pepper to the sauce. Stir to combine, then remove from heat.
In a large bowl, mix the shredded chicken, ricotta cheese, chopped spinach, and 1 cup of the mozzarella cheese.
Spread a thin layer of the white sauce on the bottom of the prepared baking dish.
Place a layer of lasagna noodles over the sauce.
