Is tomato soup gluten-free?

Answering the query – “Is tomato soup gluten free?” is slightly complex. The answer would be maybe. Tomato soup can be gluten-free, but it largely depends on the brand or the recipe if made at home. Many commercially available tomato soups often contain wheat flour as a thickener, which contains gluten. Therefore, if you’re aiming for a gluten-free diet, always check the ingredients for possible sources of gluten or look for products specifically labelled as gluten-free.
