This gut-friendly mac and cheese uses gluten-free pasta and a smooth béchamel made from lactose-free milk and FODMAP-safe cheese. Dijon mustard and vinegar add a subtle tang, while a crispy rice topping gives it the perfect crunch. You can serve it creamy straight from the pot or bake it for a bubbly, golden finish. It’s family-friendly, easy to prep, and gentle on IBS-sensitive stomachs.
