The TV ad, which launches 6 April, captures people in their own homes around teatime, reflecting what happens when families gather together for their evening meal.
The commercial features children roller-skating around the kitchen, dogs sitting at the table and families eating dinner on the sofa.
The campaign has been created by adam&eveDDB and will run across outdoor, PR, radio, in-store and social media for eight weeks.
Mark Hodge, McCain's marketing, said: "Our aim is to create excitement around teatime among new and existing shoppers.
"We are keen to help families across the UK appreciate the occasion, enjoy the good stuff and relish the simple joy of connecting over food as well as offering quality, value and convenience from our product portfolio."
