This Chicken Parmesan Casserole brings together everything that makes the classic Italian-American dish so popular—tender chicken, rich marinara sauce, and gooey melted mozzarella—but in an easy baked casserole. Instead of frying and breading each piece of chicken, everything is layered in one pan and baked until bubbly and golden.
It’s a perfect solution for busy weeknights, simple meal prep, or feeding a hungry group without spending hours in the kitchen.
