(International / UK / US) RÖMERTOPF equivalents? I have a RÖMERTOPF at home. It is a porous clay casserole dish.

I have recipes, sure. But I'm always looking for more. I'm not asking for recipes, though: I'm asking what the closest international / UK / US equivalents would be, so that I could be sure that I find appropriate recipes when looking for it.
I don't think there is really a US equivalent, but a Moroccan tagine would be close.
