Are hot dogs gluten-free? Often, but the bun isn’t
Often yes, but not always. Many hot dog sausages are made from meat, water, salt and spices with no gluten ingredients. Some add wheat-based fillers, breadcrumbs or rusk.
What to check
- The label. Look for wheat, barley, rye, malt, rusk or breadcrumbs in the ingredients, or a gluten-free mark.
- The bun is wheat unless it is a gluten-free bun. At stands and grills, ask whether gluten-free buns are toasted on the same surface.
- Toppings: fried onions can be battered; some sauces and relishes use malt vinegar or thickeners.
- In the UK and much of Europe, sausages often contain rusk (a wheat product), so check every brand.
