How can I thicken my soup recipe?

If you want to make your soup thicker, try adding a small amount of cornstarch. This can help the soup to be less thin and runny. If it is a creamy soup, instead of using skim or 1% milk, try using whole milk or even heavy cream. Both of these will add more body to the soup you are making. Not a fan of dairy? Try out coconut cream, but know this could change the flavor profile slightly.
