The Belgian international joined the Toffees in the summer from Greek outfit Olympiakos and has impressed since his £5m move.
Mirallas netted a brace on his full debut against Leyton Orient in the Capital One Cup before scoring against Swansea City in the Premier League, but the 25-year-old wants to add more goals to his game.
"I think at the moment I have more assists than I have goals," said Mirallas.
"I've provided one or two decent passes for my colleagues to score, but at the same time I'm hoping to continue to improve in front of goal and I think 10 goals is a reasonable target for my first season.
"If I can manage 10 goals that would be decent."
Mirallas scored 20 goals for Olympiakos last year.
