To ensure this recipe is gluten-free make sure all your ingredients are certified gluten free. Instead of using seasoning salt try using a gluten seasoning blend of your preference. Additionally swap out breadcrumbs, for either gluten-free breadcrumbs or crushed gluten-free crackers if you want to add a breadcrumb topping. With these adjustments you can still enjoy the experience of Melt in Your Mouth Chicken without having to compromise your gluten dietary needs.
