For the final home game of the season, USA international Pulisic was presented with yellow flowers on the Westfalenstadion pitch minutes before kick-off in the Bundesliga match with Fortuna Dusseldorf.
"Dortmund will always feel like home for me," he told supporters, who gave him a warm round of applause.
Pulisic signed for Chelsea in January but was immediately loaned back to Dortmund for the remainder of the season.
Prior to Saturday's game, he had scored three goals and provided three assists in seven Bundesliga starts and 11 substitute appearances.
But he added to his tally by opening the scoring with his fourth league goal of the season on 41 minutes. BVB went onto win 3-2.
