The Blues bounced back from Sunday's Carabao Cup defeat to Liverpool thanks to goals from Nicolas Jackson, Mykhailo Mudryk and Gallagher.
Gallagher, who scored a 90th-minute winner with a tidy finish in the box past Illan Meslier, dedicated the victory Chelsea's supporters.
"Sunday was a big disappointment and we wanted to bounce back and give the fans something to celebrate," Gallagher told Chelsea's official website. "Thankfully we did that last night.
"It was a great atmosphere. Leeds fans are always very passionate and loud, but I think our fans were great as well, especially considering the disappointment the other day.
"So I have to say thank you to them and hopefully we gave them something to celebrate."
Virgil van Dijk scored the only goal in the 118th minute at Wembley as Mauricio Pochettino's side sustained a big blow to their campaign.
Gallagher admitted it has been difficult to overcome the defeat following the short turnaround between the two games, with the FA Cup representing the only chance of silverware for the club this season.
He added: "It was really tough for the players to bounce back. Obviously everyone has been down over the last few days, but we had to make sure we were right for this match because it was such an important game.
"Physically, it was fine for me coming off the bench, but the lads who played the full game against Leeds after playing 120 minutes the other day were fantastic and we've got to give a lot of credit to them.
"It was a big shift and a good performance. I thought we dug deep and thankfully we got the win in the end."
The midfielder's strike rounded off a spirited Chelsea performance and took his tally for the season to four in all competitions.
"It's nice. I obviously like to score goals and I struggled to do that before the goals started to come, so hopefully I can continue to get more," Gallagher said.
"It was a great pass from Enzo (Fernandez) and a good goal. We were really happy to get one right at the end because obviously it meant we didn't have to go into extra time, and I think we were looking a bit tired."
