Learn how to make the best cheesy, saucy Chicken Lasagna! You can cook fresh chicken for this casserole but it’s also a great way to use up leftover chicken (or even leftover turkey from Thanksgiving!).

Ingredients for White Sauce Chicken Lasagna:
There are 4 main components to a creamy white chicken lasagna: lasagna noodles, a simple bechamel spinach sauce, and a ricotta cheese sauce. Don’t forget the chicken! You can cook your own Instant Pot Chicken or use a store-bought Rotisserie Chicken.
Pro Tip: We always cook an extra couple of noodles in case any of our lasagna noodles break while cooking.
Can I Use Canned Chicken?
We love canned chicken recipes like our easy Chicken Melts and Buffalo Chicken Dip since we always have it on hand in our pantry. Using canned chicken will work for chicken lasagna, just be sure it is well-drained.
How to Assemble Creamy Chicken Lasagna:
The process of assembling a chicken lasagna is simple. We found it’s easiest to spread the thicker ricotta sauce over the noodles and ladling the spinach sauce ensures the chicken layer is moist and juicy. For best results, follow this order.
- Spread 1/2 cup spinach sauce on the bottom of a 9×13 casserole
- Add 3 noodles, 1/2 ricotta sauce, 1/2 shredded chicken, 1/3 of spinach sauce
- Add 3 noodles, 1/2 ricotta cheese, 1/2 shredded chicken, and 1/3 spinach sauce
- Remaining 3 noodles, remaining 1/3 sauce, and sprinkle on reserved 1 cup cheese.
Tips for Reheating Chicken Lasagna:
This white sauce lasagna reheats really well and leftovers are just as enjoyable as freshly baked lasagna. Here are some tips for reheating so the lasagna doesn’t dry out.
- Add Water – Since noodles will naturally soak up some liquid in the lasagna as it sits, it helps to sprinkle on a little bit of water before reheating in the oven or the microwave.
- Visual Cues – Heat until the edges bubble and the cheese is fully melted on top.
- 165˚ F Center – You should reach a safe internal temperature of 165˚F on an instant-read thermometer.
How Long Can Leftover Lasagna be Stored?
Chicken lasagna will keep up to 4 days in the refrigerator if you were using freshly cooked chicken. You can also wrap tightly in several layers of plastic wrap and freeze up to 3 months.
This lasagna is a meal in itself. All you need is a simple salad to go with it like our Classic Caesar Salad or fresh Beet Salad with Arugula.

- Add 3 noodles, remaining 1/3 sauce, and sprinkle on reserved 1 cup cheese.
- Cover and Bake: Arrange 10-12 toothpicks over the top to keep the foil from touching the cheese then cover with a large sheet of foil. Bake on the center rack in a preheated oven at 375˚F for 45 minutes then uncover and broil 2-3 minutes to brown the cheese. Rest at least 10 minutes uncovered before slicing.

I halved the recipe for an 8×8 pan. Although it was tasty, we felt it was a bit dry. Perhaps halving the béchamel sauce was the fault. Suggestions?
HI Sherry, It may not have been quite enough ingredients for an 8×8 pan without adjusting the bake time – a thinner lasagna would cook faster.
Hi, Can you used frozen spinach. Love all of your recipes. Keep them coming.
Hi Terry! Yes, you can use frozen spinach, just thaw it and drain it first.
This recipe is one of my favorites! It is jam packed with flavor and reheats very well. Also, a plus, it’s so simple yet so impressive to guests!
Can use freshly baked chicken or even used chicken from whole chicken I have boiled?
Yes, you sure can.
Can you make this a day ahead of time? If so, do you wait to bake it or bake and then reheat the next day?
This reheats great, see my note above “Tips for Reheating Chicken Lasagna.”
Also- you can assemble this the day before and bake it fresh but it will require some additional time to bake since it will be cold. I hope you love the recipe!
