Customers local to the Harp, Abergele, can call, text or message the pub online up until 4pm every Saturday to place an order for a roast and choose their preferred meat.
Maria Brien, of the Harp, told the Daily Post: "We have always done a good trade with our Sunday dinners at the pub but we thought there must be a lot of people who would love a Sunday dinner but can't be bothered cooking it or coming to the pub.
"Often, people fancy a roast but the idea of cooking it and washing up all the dishes puts them off – there are a lot of older people in the Abergele area and lots of families who we think would love this."
The pub has already attracted significant attention on social media since announcing the scheme and has reportedly been asked if it will deliver roasts further afield in future.
JD Wetherspoon recently called curtains on its Sunday roast offer, announcing that the traditional dish would no longer be served following Mother's Day (6 March).
The decision has been made so the chain could focus on its core food offer, a spokesperson told the Publican’s Morning Advertiser (PMA).
Many JD Wetherspoon customers took to social media to air their grievances with the chain over its decision.
One said on Twitter: "It's popular – it's perfect the way it is. Yes, you could put the prices up a tiny bit if that's really necessary, but keep our Sunday roasts."
A poll of PMA readers reported that there were no worries for the longevity of the Sunday roast across the sector, with 85% saying the roast was a great British classic and would be on pub menus for the foreseeable future.
