I don't think 1-1 is the right time. If you have a team of 15 people, you would need to repeat the same thing 15 times. Better to give an update of what you are working on (as a manager) for the whole team once.
That's a large team. I don't think it makes sense to have 15 direct reports. You probably want to split that into 2 teams so you can feed your team with two pizza boxes.
If you do have a team that large, then you need to have a weekly or biweekly meeting with an agenda set beforehand. You can make announcements and possibly have a rotating presentation by somebody from the team about what they've been working on.
If you are managing this many people, you are managing people, projects and comms.
