While mashed potatoes is a tried and true recipe, some unexpected additions can enhance the dish. One such inclusion is French onion dip, which can be a substitution for milk.

What sets the dip apart is the bonus of the French onion flavor profile. This enhances the flavor and delivers the creamy consistency expected from its dairy counterparts.

Dairy products contain casein proteins, which limit the release of starch during mashing and prevent potatoes from expanding and turning into a sticky mess.

Many store-bought French onion dips contain milk products, which provide the necessary components to engage with mashed potatoes and help them remain creamy.
