The 26-year-old's current deal was due to expire at the end of this season.
"It's a weight off my mind, so now I can look to the long-term future. The club has a vision, and that's why I've signed and stayed on.
"We got to the Premier League in three years, and now the club has a vision of playing European football - and we want to get there as soon as possible."
