Abby Wambach put the home side in front within two minutes after latching onto an Alex Morgan cross-shot at the back post, but the lead lasted just 12 minutes.
A sensational solo goal by Anja Mittag brought the visitors back on terms, with the No11 driving at the USA defence before smartly lifting the ball over Hope Solo to equalise.
Despite some enterprising play, no more goals followed and the tie finished 1-1, with the two teams set to resume battle on Tuesday at Rentschler Field in East Hartford.
The draw extended Olympic champions USA’s unbeaten run to 17 matches, with the Germans now without defeat for 15 games themselves. FIFA Women’s World Cup winners Japan were the last team to beat both sides.
