Most onion dip packets are powdered dry mixes intended to be reconstituted. Some listings are described as ready-to-use or more fully prepared mixes.
Some onion dip packets carry labels such as organic, certified gluten-free, and kosher, depending on the product.
They are commonly mixed with sour cream to make a creamy dip. Some are also promoted as simple mixes for soups or other dip-style preparations.
Onion dip packets are marketed for parties, gatherings, and entertaining as crowd-pleasing dips served with chips or vegetables, and they are also suggested for everyday meals.
Some listings explicitly state they contain no artificial colors or flavors, and at least one product notes it does not contain any of the nine major allergens.
