The 19-year-old midfielder joined the Alex at the end of October and has made 15 appearances in all competitions, netting his first senior goal against Port Vale in November.
"I am delighted to stay. I've enjoyed the experience and feel I am developing as a player," Evans told Crewe Alex Player.
"I've spoken to Manchester City and they know that Crewe is a great club for me to play and develop.
"I am just grateful to Crewe for giving me the opportunity and now we have to build on what we achieved against Sheffield United on Saturday."
