Notes

  • Recipe notes: This crouton recipe is made with sourdough bread, but any type of bread can be used. We like ciabatta bread, rye bread, or a thick whole grain loaf for homemade croutons.
  • Leftovers + storage: After croutons have cooled, store in an airtight container at room temperature for 5 days, or in the refrigerator for 6-7 days. We do not recommend freezing as the croutons will lose their crisp texture after thawing.
  • Nutrition notes: This recipe uses all plant-based ingredients, making it suitable for vegan diets.
