To make these Fried Green Tomatoes gluten free, substitute the all-purpose flour with a gluten-free flour blend and use gluten-free breadcrumbs or gluten-free panko in place of standard breadcrumbs. Cornmeal is often naturally gluten free, but it is still important to check the label for cross-contact warnings if needed. Also confirm that the seasoned salt, hot sauce, and any optional seasonings are labeled gluten free, since ingredients can vary by brand. Once those swaps are made, the recipe adapts very easily.
