Notes
COOKED CHICKEN - This is a great recipe to use rotisserie chicken! But if you have chicken you want to use I recommend poaching the chicken or baking it at 350°F for about 25 minutes until they reach 165°F internal temp. MAKE AHEAD - To make this Chicken Lasagna a day ahead and cook the next day, assemble completely, cover with foil and pop in the fridge overnight. The next day remove from the fridge and bake at 375°F for 1 hour, then remove the foil and bake another 10-15 minutes. Finally broil for 3-5 minutes to brown the top.I wouldn't recommend freezing this lasagna because of the cream and milk content.

Make sure to squeeze all the water from the spinach. I like to use a fine mesh colander and press it firmly.
Spray non stick spray on a rimmed baking sheet and lay the cooked lasagna noodles out to cool. This prevents the noodle from sticking together while you assemble the other ingredients.
Use a deep dish 9x13 casserole pan so the lasagna will fit!
Place the lasagna pan on a rimmed baking sheet so if the lasagna boils over you avoid a mess in the oven.
Spray the underside of the foil before placing it on the lasagna, it will help prevent the cheese from baking to the foil.
Let the lasagna cool for 15-20 minutes so it sets up before you cut it.
