If you’re looking to make this Baked Chicken Parmesan Casserole gluten-free, don’t worry—it's totally doable! Just swap out the regular rigatoni for your favorite gluten-free pasta (there are so many good ones out there now). For the chicken, use gluten-free flour and breadcrumbs. You can easily find Italian-style gluten-free breadcrumbs at most grocery stores, or make your own by blending gluten-free crackers or bread with some Italian seasoning. And voilà, you’ve got yourself a gluten-free version that’s just as crispy, cheesy, and delicious as the original!
