In a medium bowl, whisk together the condensed cream of onion soup and the dry onion soup mix until well combined. The mixture will be thick and very flavorful.
Pour the onion soup mixture evenly over the frozen fries, using a spatula to spread it so most of the fries are lightly coated. It doesn’t have to be perfect—everything will melt together as it cooks.
