Instructions to make Chicken lasagna
Cook Noodles & Prep:

Place a pot or large saucepan over medium heat, add 1 Tbsp olive oil and saute onions for 3-4 minutes or until softened. Add 4 Tbsp butter and whisk in 1/3 cup flour. Continue whisking 3 minutes or until flour mixture is golden. Add 2 1/2 cups chicken broth, 1 1/2 cups half and half, 2 tsp salt, and 1/2 tsp black pepper. Whisk until smooth and simmer 5 minutes until thickened to a light gravy consistency. Add minced garlic and chopped spinach, and stir to combine then remove from heat.
Make the Ricotta Cheese Sauce:
In a large bowl, whisk together: ricotta, egg, 2 cups mozzarella cheese, 1/4 cup parmesan, and 1/4 cup parsley.

Add a little bechamel sauce on the bottom of a 9×13 casserole dish, add 3 noodles, Add 1/2 ricotta sauce, 1/2 shredded chicken then ladle 1/3 of spinach sauce over the chicken. Insert 3 noodles, 1/2 ricotta cheese, 1/2 shredded chicken, and 1/3 spinach sauce Add 3 noodles, remaining 1/3 sauce, and sprinkle on reserved 1 cup cheese.
Cover and Bake:
