The Hammers captain scored and assisted during the win at the London Stadium, as Nuno Espirito Santo's side notched their third straight win in all competitions.
Bowen put in a delightful cross which was met by Crycensio Summerville for West Ham's opening goal, before finding the net himself later in the first half via the penalty spot.
His display earned him an 8.3 player rating, a score also equalled by Aston Villa midfielder Emiliano Buendia this weekend.
West Ham will look to make it three Premier League wins in succession when they visit Chelsea on Saturday evening.
