Making the EASY White Chicken Lasagna can be straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Noodles: Cook the lasagna noodles according to the package instructions but slightly undercook them, as they will continue to cook in the oven.
3. Mix Ingredients: In a large bowl, combine the cooked shredded chicken, ricotta cheese, spinach, garlic powder, onion powder, salt, and pepper.
4. Layer Ingredients: Spread a thin layer of Alfredo sauce on the bottom of a 9×13 inch baking dish. Place three noodles over the sauce.
5. Add Chicken Mixture: Spread a portion of the chicken mixture over the noodles, then sprinkle with 1/3 of the mozzarella cheese and 1/3 of the Parmesan cheese.
6. Repeat Layers: Continue layering with Alfredo sauce, noodles, chicken mixture, and cheeses until all ingredients are used, finishing with a layer of noodles topped with Alfredo sauce and remaining mozzarella cheese.
7. Cover and Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes.
8. Remove Foil: Remove the foil and bake for an additional 10–15 minutes or until the cheese is bubbly and golden brown.
9. Cool: Let the lasagna cool for about 5–10 minutes before slicing it into squares for serving.
