To make our delicious Sausage Green Bean Potato Casserole gluten-free it's essential to choose the sausage. Some sausages contain ingredients or seasonings that have gluten so it's important to select a sausage that is clearly labeled as gluten-free. Also pay attention to the spices you use, like Slap Ya Mama® seasoning. While this seasoning is naturally gluten-free there is a risk of cross-contamination during processing. Therefore always opt for brands that guarantee a gluten-free product. This simple substitution doesn't compromise the taste or texture of the dish allowing everyone to enjoy the comforting goodness of this casserole without any worries, about gluten.
