Get a big taste of the season with this marvelous Rosemary Chicken Lasagna Recipe and feel no guilt. This lighter version delivers all the fantastic flavors of a more fattening lasagna, but for a lot less fat and calories.

Using whole wheat noodles helps add more fiber and protein which really make this a satisfying serving. The bold rosemary perfectly seasons everything and the touch of lemon zest on top gives it a lovely hint of citrus flair without being overpowering.

It’s truly an exceptional Weight Watchers Lasagna Recipe that is perfect for fall and winter. I served it with some roasted asparagus spears and a light salad, and everyone raved about it. Enjoy!

  1. This was good! I halved the recipe (only 2 of us). Would have liked a bit more moisture, however. Next time, I would lower the temp or cook for less time. Don’t leave out the lemon zest–definitely adds a unique flavor to this recipe without being overwhelming
