Omit posts from category list using template tag

I think the title pretty much sums it up. I’d like to use the template tag rather than the widget in my sidebar. Works fine but each category also display the posts in that category and forces you to click a post. I need to be able to click a category name to display the posts in that category on a page. There is an option not to “list posts” in the widget. Can I do that using the template tag?
