This cheesy baked eggplant Parmesan has no breading, which means it's easier to make than the traditional version. There's no dredging or frying—instead, the eggplant is roasted until tender before being layered in the casserole dish with a tangy homemade tomato sauce, mozzarella and Parmesan cheese. And without breading, this satisfying eggplant Parmesan is also gluten-free!
