Is tempura gluten-free or safe for celiac disease?
Avoid
Traditional tempura batter is made from wheat flour. Tempura should be avoided by anyone with celiac disease or a wheat allergy.
Why this verdict
- Tempura batter is made from cold wheat flour and water — gluten is essential to its texture.
- The frying oil is shared with all other tempura items in a busy kitchen.
- Dipping sauce (tentsuyu) sometimes contains soy sauce, adding a second gluten source.
Watch out for
- Tempura crumbs (tenkasu) sprinkled over ramen, sushi, or salads — these are pure wheat.
- Rice paper wraps or spring rolls served alongside tempura using the same oil.
Safer alternatives
- Sashimi (raw fish sliced plain, no batter)
- Grilled yakitori skewers without soy-sauce tare
- Rice dishes such as donburi without tempura topping
What to ask staff
- Is the tempura batter made with wheat flour, or is there a rice-flour alternative?
- Is there a dedicated gluten-free fryer?
- Does the dipping sauce contain soy sauce?
Frequently asked
Is rice-flour tempura available?
A small number of restaurants offer rice-flour tempura for gluten-free diners, but it is uncommon and still risks cross-contact unless a separate fryer is used.
