Match ends, Arsenal Women 4, TSG 1899 Hoffenheim Ladies 0.
Tobin Heath scored her first goal for Arsenal as the Women's Super League leaders beat Hoffenheim in the Champions League.
The home side took the lead midway through the first half when Kim Little converted a penalty.
Summer signing Heath made it 2-0 on the stroke of half-time when she stabbed in a knockdown from close range.
Vivianne Miedema bundled in a third before Leah Williamson headed in a late fourth.
Victory means Arsenal are second in Group C with three points, behind leaders Barcelona who have six points.
Jonas Eidevall's side have enjoyed a superb start to the season with five wins from five in the Women's Super League but their European campaign got off on the wrong foot when they were beaten 4-1 by Barcelona.
This, however, was the perfect response to that thrashing as they recovered from a slow start to dominate Champions League newcomers Hoffenheim.
"All in all it is our strongest performance so far in the season," said Eidevall.
"The way we moved the ball and our passing game in their half was the best we have had this season. I am very pleased with the performance."
Little got the ball rolling by scoring her fifth goal of the season from the penalty spot after Beth Mead had been fouled inside the box.
Arsenal were causing their German opponents problems with their high press and duly added a second just before the break when Heath, who joined on a free transfer in the summer having played for Manchester United last season, fired home after Miedema had nodded the ball into her path.
Dutch forward Miedema then got on the scoresheet when she found herself in the right place to bundle in a loose ball after Jordan Nobbs' superb strike had been kept out by Martina Tufekovic.
Arsenal keeper Manuela Zinsberger ensured her side kept a clean sheet with a big save late on to keep out Katharina Naschenweng's deflected shot, before Williamson powered home a header in the final few minutes to wrap up a dominant win.
Arsenal fan Heath was delighted to score her first goal for the club and is confident there is more to come from the team.
"It felt really good to get off the mark," the USA international said.
"Obviously with the whole team bouncing back, getting four goals today was a good response. We showed a lot of character.
"The quality of players here has made it fun and easy and Jonas has brought a style that will take the club to the next level. This team is ambitious to get better and take the next step. We grow with each game."
