How to protect special content from being listed in Google's pages

Doubt I explained it best in the title, but I am familiar with using the command site:domain.com in Google. I am fine with Google crawling my site, but I don't want all the blog post titles listed by date when you put that command in. I'm not trying to protect that specific part of that content from being indexed in Google, I just want to prevent people from merely typing that command in and seeing every blog post title.

Any way to do this without protecting the folder? This specific part of the site is free content, but putting the command in Google would probably stop people from signing up for an offer in my content gateway protecting the page.
