White Castle sliders are not inherently gluten-free, as they are made with a wheat-based bun that contains gluten. However, White Castle does offer some menu options that may be suitable for those who are gluten-sensitive or have gluten allergies. It is important to note that while certain items may not contain gluten as an ingredient, cross-contamination may occur during food preparation, which can pose a risk for individuals with celiac disease or severe gluten intolerance. White Castle’s website may provide additional information regarding their food preparation practices and the possibility of gluten-free options. For individuals following a gluten-free diet, it is always best to review the current menu and inquire about the specifics of an order at the restaurant. This ensures that diners can make informed choices that best suit their dietary needs.
