Ok.. had this happen in a couple of recent games. (Noble level)
My strategy was basically found city, make worker, then make barracks, then one archer (usually) for defense, then make about 3 more cities, all with barracks. 1 or 2 archers is sufficient for defense, since all the barbs have is warriors for a while.
By then I have iron and the techs for a swordsman type unit. I start churning them out continuously - the only time I stop making military units is to make a library when available.
I stack them in groups of usually 5 to 10 and move them as a unit into the unoccupied lands. By then the barbs usually have several smaller cities.
And in the games I played like that I added anywhere from 4 to 10 NEW cities without ever making another settler, just from taking over barbarian cities (one was quite large - size 13).
In my best effort (lucked out on having lots of open land and no nearby civs) I ended up with 15 cities, of which I had only founded 5. On my worst I only got 4 barb cities, but still ended up ahead of the game in land area.
The major key to this of course is to have Iron available, but usually if there are some hills around you will have it, and copper and gold also.
