The Belgian forward struck for three goals in 11 minutes to blow open the Premier League match as David Moyes's new side fell to his old one.
SUNDERLAND, England (AP) — Romelu Lukaku fired an 11-minute hat trick to end his 11-game Premier League scoring drought in style as Everton beat Sunderland 3-0 on Monday.
The Belgium striker struck with 60th and 68th-minute headers and then completed his hat trick with 19 minutes remaining at the Stadium of Light to condemn former Toffees boss David Moyes to a third defeat in four matches this season.
Sunderland might have taken a 10th-minute lead when Adnan Januzaj's shot was blocked and looped perfectly into the path of Jermain Defoe, who sent his first-time volley over the bar.
Lukaku broke through for Everton when Idrissa Gueye crossed from the right and he rose unopposed to head past Sunderland goalkeeper Jordan Pickford.
The Belgian rattled the crossbar after turning smartly four minutes later, but made sure of victory when summer signing Yannick Bolasie picked him out unmarked at the far post.
The home side's misery was complete in the 71st when Lukaku helped himself to a third after Kevin Mirallas had played him through on Pickford.
Revitalized under Ronald Koeman, unbeaten Everton has 10 points, the same as second-placed Chelsea.
Sunderland is 19th with a single point.
