How to use Regex to find exact same sequence in php?

I want to use regex to delete all characters after the exact sequence 'roast'. I tried the following. 

echo preg_replace('/^[^roast]+/', '', "I ate a big roast and it was delicious.");

However, if there is one character from the list is found;not a sequence as a whole then regex is returning a match.In this case it is getting the 'a' of 'ate' as a match.

What I want: " and it was delicious"

What I am getting: "ate a big roast and it was delicious."

Your current regex matches a sequence of characters other than r, o, a, s, or t, at the start of the string.

You want any string, followed by roast:

.+roast
