The group has signed a deal with Roadchef, one of the largest motorway services operators in the UK, to bring its Hot Boxes and salads to two sites at Norton Canes on the M6 toll and Stensham South on the M5 in early August.
The partnership will create nearly 60 jobs, with more restaurants set to open over the next five years.
Roadchef says it is aiming to offer travellers a wider choice of food which better reflects the ‘diversity’ of the UK high street.
“We have always said we want Leon to be where it was most needed – either on the high street or easy to find when you’re out and about,” says Leon managing director John Upton.
“This new partnership with Roadchef will help us provide fun, fast, fresh Leon food to the millions of people who use our motorways every day.”
In 2016 Leon signed a five-year deal with SSP to open at railway stations across the country.
The group, which was founded by John Vincent and Henry Dimbleby in 2014, currently operates 47 sites in the UK.
Last August Leon outlined plans to open 50 new restaurants by 2020 after securing £19m funding OakNorth bank.
