The Full Answer
Polenta is coarsely ground corn cooked into porridge or set and sliced. Corn is on the Celiac Disease Foundation's list of naturally gluten-free grains, and the Gluten Intolerance Group suggests sliced polenta under marinara or Bolognese, or in lasagna, as a stand-in for pasta.
Labels still matter because of processing. Bob's Red Mill sells a regular polenta and a separate Gluten Free Yellow Corn Polenta that is "Processed in our dedicated gluten free facility". If you have celiac disease, buy the labeled one; the regular product is the same grain but is not labeled gluten-free.
Pre-cooked polenta tubes need the same label check, and at restaurants ask whether polenta is dusted with flour before frying or cooked in a shared fryer.

Celiac Safety Glossary
- Celiac disease
- Celiac disease is a serious autoimmune disorder in which ingesting gluten — a protein found in wheat, barley, and rye — triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
