In my Laravel application I used Auth::user() in multiple places. I am just worried that Laravel might be doing some queries on each call of Auth::user()

Kindly advice

No the user model is cached. Let's take a look at Illuminate\Auth\Guard@user:

public function user()
{
    if ($this->loggedOut) return;

    // If we have already retrieved the user for the current request we can just
    // return it back immediately. We do not want to pull the user data every
    // request into the method because that would tremendously slow an app.
    if ( ! is_null($this->user))
    {
        return $this->user;
    }

As the comment says, after retrieving the user for the first time, it will be stored in $this->user and just returned back on the second call.

Please note that this is not persistent between different requests. What I mean is that each time there is a new request (e.g: User refreshes the page), regardless of the inner caching, the driver goes to database every time. – Arda Sep 2 '15 at 20:04

For same Request, If you run Auth::user() multiple time, it will only run 1 query and not multiple time. But , if you go and call for another request with Auth::user() , it will go and run 1 query again.

This cannot be cached for all request after first request has been made due to security point of view.

I see use of some session here , http://www.rebootcode.com/php/laravel/using-session-against-authuser-in-laravel-4-and-5-cache-authuser/

Thanks
