Rejuvenated under interim boss Renee Slegers, who has overseen a terrific revival since replacing Jonas Eidevall, the Gunners strode to victory through Alessia Russo, Frida Maanum and Stina Blackstenius and were never seriously troubled by their meek hosts.
Fresh from a 4-0 thrashing of Juventus in the Champions League, Arsenal had Spurs on the ropes straight away and needed just 63 seconds to draw first blood through a slick Russo finish.
The ex-Manchester United striker scored the second-quickest goal in Arsenal's WSL history, and that rapid opener was a sign of things to come, as Slegers's side continued to huff and puff while barely allowing Spurs to venture out of their own half.
The Gunners allowed a couple of opportunities for goal number two to pass them by, but thanks to some more pitiful Tottenham defending, Maanum swept home a well-worked second midway through the first half.
Robert Vilahamn's team belatedly found some attacking verve approaching half time, but their efforts were largely futile, and they could have easily been three or four down had the visitors been a touch more ruthless in the final third and a touch less casual in their own defensive third.
The hosts cut more combative figures at the start of the second half, albeit without the penetration needed to cut through the Arsenal defence, and the result was put beyond any doubt when substitute Blackstenius calmly slotted home the visitors' third.
The Gunners' emphatic triumph has seen them open up a three-point lead over Manchester United in fourth place in the WSL table, although the Red Devils have two games in hand, and they sit four points behind leaders Manchester City having played a game more.
Meanwhile, Spurs sit seventh in the division and are left to rue another dismal defensive display, one which has seen them become the first side in the league this season to concede over 20 goals.
TOTTENHAM VS. ARSENAL HIGHLIGHTS
Alessia Russo goal vs. Tottenham (2nd min, Tottenham 0-1 Arsenal)
Slegers's side are not messing about at the Tottenham Hotspur Stadium!
Mariona Caldentey threads a pass through to Russo - aided by a deflection - and the England international lashes a terrific left-footed strike into the far corner to give the Gunners an immediate lead.
Russo's first-time effort is officially the second-fastest Arsenal goal in the history of the WSL, only behind Jordan Nobbs's 28-second strike versus Liverpool 10 years ago.
Frida Maanum goal vs. Tottenham (22nd min, Tottenham 0-2 Arsenal)
So, so easy for Arsenal.
Leah Williamson, Maanum and Kim Little exchange some crisp one-touch passes, and the Norwegian continues her run into the box, where Little picks her out under no pressure whatsoever.
Maanum has time to take the ball on her left foot, readjust her position and find the bottom corner with a composed right-footed finish, and Slegers's team have the second goal that their dominance warranted.
Stina Blackstenius goal vs. Tottenham (66th min, Tottenham 0-3 Arsenal)
An immediate impact from the substitute Blackstenius, and akin to Arsenal's second goal, this one is all about the slick one-touch passes.
Maanum drives infield and finds Caldentey, who picks out the run of Blackstenius with an exquisite, delicate pass, and the Scandinavian striker coolly picks out the bottom corner one-on-one with Becky Spencer.
PLAYER OF THE MATCH - MARIONA CALDENTEY
Goalscorers Russo and Maanum would have both been worthy selections for the player of the match prize, but scintillating Spaniard Caldentey just edges this vote, having had a direct hand in two of Arsenal's three efforts on the day.
The 28-year-old was not credited with the assist for Russo's goal thanks to the deflection, but her deft pass through to Blackstenius was the dictionary definition of sublime, while she also put in two tackles and two clearances to quell some Spurs attacks in their tracks.
