As low-income couples seek to avoid the high costs of a traditional wedding, such ceremonies have become more common.
According to local media, the brides-to-be were kept out of sight in a separate wing and did not appear until after lunch.
The Kabul event was organized by a charity, which also provided the newlyweds with items such as a carpet and household appliances to help them begin their married life.
At the low-key ceremonies, an official from the ministry for the promotion of virtue and the prevention of vice spoke.
While the Koran was read aloud, dancing and music have been effectively banned by the country’s Taliban rulers since their return to power in August 2021.
The brides and grooms were then driven away in cars adorned with green ribbons and red plastic roses shaped like hearts.
Roohullah Rezayi, 18, told AFP news agency that he couldn’t afford a solo wedding.
“A traditional wedding would have cost us at least 200,000 to 250,000 Afghanis [£2,220 to £2,770; $2,800 to $3,600] but this time it will be between 10,000 and 15,000 Afghanis,” he added.
According to the agency, the young man, a member of the Hazara Shia Muslim minority from Ghor province, earns only 350 Afghanis per day doing odd jobs.
“We invited 35 people from our two families, otherwise it would have been 300 to 400,” he went on to say.
According to AFP, some of the grooms-to-be had been waiting a long time.
“I’ve been waiting for this day for three years,” Samiullah Zamani, a 23-year-old farmer from Kabul province, said. “I can’t wait to see her.”
