The deli in Notting Hill is to reopen tomorrow (20 May); with the site in Islington due to reopen on Saturday (23 May).
The delicatessens will serve a capsule collection of 'essentials' including croissants and other morning pastries; fruit tarts; chocolate fondant cake; aubergine salad; and broccoli and cauliflower tabbouleh.
A changing selection of mains will also be available to take home.
Both delicatessens will operate a queue system outside, with a limited number of customers allowed in the stores at any one time to allow for social distancing.
Alternatively, those wishing to avoid the queues can order from the delis using click-and-collect; or opt for delivery instead.
From Friday (22 May), the Ottolenghi online shop will also be available again, stocking biscuits; granola spice collections; oils and vinegars; and a range of Ottolenghi-branded linens.
Ottolenghi's delicatessens in Belgravia and Spitalfields remain closed, with no details yet on when they will reopen too.
Both Soho's Nopi, and ROVI in Fitzrovia, also currently remain closed currently in line with the Government's Coronavirus shutdown.
Later this month, Ottolenghi group founder Yotam Ottolenghi will take part in a virtual cookalong banquet to raise money for Chefs in Schools, alongside chefs Angela Hartnett, Jeremy Lee and Thomasina Miers.
The online event, which is being organised by restaurant and consumer food supplier Belazu and will be held on Friday 29 May from 6pm, will give people at home the chance to cook a vegetarian feast.
