You can use middleware, and check if that query is on cache, if not you can add it. There is an example in Laracast.

It's for laravel 4 but you can make it similar in laravel 5 with middleware

Thanks! It's an option.

But with middleware i can't set custom cache time and i don't want to cache ALL queries :)

But thanks anyway

It has been a while, but just in case someone runs across this question, there is a package that does just this. https://github.com/dwightwatson/rememberable

'Rememberable is an Eloquent trait for Laravel 5.0+ that brings back the remember() query functions from Laravel 4.2. This makes it super easy to cache your query results for an adjustable amount of time.'
