Add sour cream to a bowl and blend it separately.
Then add a cup of mayonnaise and stir well.
In the end, add a packet of ready-made French onion mix and blend the mixture quite well so that all the flavors come out as one.
You can also add pinches of black pepper and salt if you like. Chill it in the fridge for at least an hour by your choice. So that it will settle down and will have a good consistency.
Top your dip with some herbs such as coriander leaves and oregano and serve it on your platter.
