The Favourite star visited the charity, which is currently serving 500 meals a day, and assisted in preparing 100 'rainbow veg tagines with crusty bread pieces and pearl barley'.
She then joined the company's cargo riders to 'do some non-contact deliveries' around the London borough of Hackney.
On Instagram, Made In Hackney said: "Meal recipient Lynn who attended MIH cookery classes in pre-COVID times, was brilliant when the food arrived. She rubbed her eyes and said, 'I've not got my glasses on but you look just like Olivia Colman'. Classic."
According to photographer Lucy Young, who snapped the celebrity delivering food, Colman said: "What I witnessed yesterday — the dedicated, kind community-led work of The Felix Project and Made in Hackney — has convinced me there is indeed great cause to be hopeful."

Last month, Made In Hackney pivoted from offering free community cookery classes to the vulnerable, to offering a free food delivery service to those same people.
It also launched an emergency crowdfunder to help it reach as many people as possible - by delivering food and checking in with them - for as long a time period as possible. More than £71,000 has been raised so far.
