To prepare this crab cakes recipe gluten-free, substitute the crushed buttery crackers with certified gluten-free crackers or gluten-free panko breadcrumbs. Additionally, verify that all condiments—particularly the mayonnaise and mustard sauce—are labeled gluten-free, as hidden gluten can sometimes be present in processed ingredients. This simple substitution allows you to enjoy the same rich flavor and crispy texture without compromising dietary needs.
