Yes, you can use gluten-free alternatives like cornstarch or arrowroot powder to thicken the soup without adding gluten.
Cornstarch: Cornstarch is a popular gluten-free thickener that works well in soups. Mix cornstarch with a small amount of cold water to create a slurry before adding it to the soup. This helps prevent clumping and ensures even thickening.
Arrowroot powder: Arrowroot powder is another gluten-free thickener that works similarly to cornstarch. Mix it with cold water before adding it to the soup to thicken it. Arrowroot powder tends to give a glossy finish to the soup.
When using either of these alternatives, start with a small amount and gradually add more until you reach your desired consistency. Keep in mind that some thickeners may alter the taste or texture slightly, so it's best to experiment and adjust according to your preferences.
