Natasha Flint scored the only goal as England Under-23s edged host nation Norway in the opening match of the annual Nordic Tournament.
Some patient build-up play led to Jodie Brett playing in the Blackburn Rovers striker who calmly rounded the keeper and chipped an angled shot into the empty net.
Melanie Raey’s side face USA on Friday before finishing the round-robin competition against Sweden on Monday.
