On my personal blog, I set the main page to a static page. However, I also wanted a menu item to the blog posts. There was nothing in the Menu editor, but the solution is quite easy if you know how.

1. Create and publish an empty page. I called mine “Blog”.
2. In (Dashboard) -> Settings -> Reading, there is a drop down called “Posts page”. Select the empty page you just created. Save your changes.
3. Under Appearance -> Menu add the Posts page to your menu. Save the menu.

When you now click on this menu item (or navigate to the page some other way) it will show the blog posts list as normal.
