Is tofu gluten-free? Plain tofu is, check marinated and fried tofu

UPDATED=2026-09-28READ=2 MINREVIEW=HTGF EDITORIAL

Yes, plain tofu is gluten-free. It’s made from soy milk set with a coagulant, and soybeans contain no gluten.

What to check

  • Marinated, smoked and flavoured tofu: often seasoned with soy sauce, which is usually brewed with wheat.
  • Fried tofu in restaurants: coatings can contain wheat flour, and the fryer may be shared.
  • Tofu in dishes: the sauce is where the gluten usually is, so ask what’s in it.
