The Scottish Government-funded Meal Makers scheme will use a website to connect volunteers with older people.
Volunteers will cook an extra meal and deliver it to the person they are matched with.
The Government and the Rank Foundation, a charitable trust, are both providing £60,000 to fund a pilot scheme in Dundee.
The project will be run by the charity Food Train, which provides befriending, household support and grocery shopping, with the help of Community Food and Health (Scotland), which works in low income communities.
Health Minister Michael Matheson said: "Reducing health inequality is one of the priorities of this Government. But we know that the solutions don't lie exclusively with the health service.
"One of the best ways to reduce health inequality is to bring people together, break down barriers in the community, and reduce isolation. Another key way is to improve diet and the availability of nutritious food, so Meal Makers is beneficial on a number of levels.
"I believe there are plenty of people out there who would love to help an older person in their community, but might not know how to go about it. Meal Makers uses an accessible website to make that connection."
