Do instant mashed potatoes contain gluten?

No, instant mashed potatoes do not typically contain gluten. Gluten is a protein found in wheat, rye and barley, but instant mashed potatoes are typically made from dehydrated potatoes, water, salt, and other seasonings. However, some brands of instant mashed potatoes may contain gluten-containing ingredients such as wheat flour or malt extract, so it is important to always check the ingredient list before consuming.
