The result leaves Arsenal third in the Women’s Super League, but only three points behind Manchester United – who beat West Ham 2-0 in an historic clash at Old Trafford earlier in the day – with a game in hand.
Meanwhile, Tottenham’s winless run now stands at seven games and they stay in eighth place.
The visitors could have been ahead early on after Jordan Nobbs’ two long-range efforts forced Rebecca Spencer into making good saves.
The Gunners made the breakthrough after 25 minutes when Foord combined with Noelle Maritz on the right-hand side before slotting the ball into the bottom corner.
Arsenal doubled their advantage in the 34th minute after a Miedema wonder-strike, with the Netherlands international volleying home a McCabe corner.
Arsenal completed the scoring in the 60th minute after McCabe pounced on a defensive error before calmly rolling the ball into the back of the net.
