Cut cabbage into quarters, separate the leaves, and boil for 3 minutes. Drain.
Combine all Alfredo ingredients except the chicken and cornstarch slurry. Simmer for a few minutes, then stir in the slurry until thickened. Add chicken.
Mix cottage cheese, egg, Parmesan, and parsley.
Layer cabbage → Alfredo chicken → cottage cheese → mozzarella. Repeat until all layers are complete and finish with mozzarella.
Bake at 400°F for 30 minutes.
After baking, I like to use a turkey baster to remove any excess liquid from the dish before serving!
