The Blues last won the competition in 2017-18, recording a 1-0 win over Manchester United in the final, with Eden Hazard's first-half penalty deciding the contest in London.
Thomas Tuchel's side will enter the contest off the back of an impressive 3-0 victory at Leeds United in the Premier League on Wednesday, which has left them third in the table, eight points ahead of fifth-placed Tottenham Hotspur.
Chelsea will finish their Premier League season against Leicester City and Watford but will currently be fully focused on securing more FA Cup glory this weekend.
Here, Sports Mole has taken a look at Chelsea's route to the FA final, starting with the third-round success over Chesterfield and ending with their semi-final victory over Crystal Palace.
Third round (5-1 vs. Chesterfield)
Chelsea hardly had to break a sweat in their third-round success over Chesterfield, with the Blues scoring five times in the opening 55 minutes of the contest before Akwasi Asante netted a late consolation.
Andreas Christensen then added a fourth in the closing stages of the first half before Hakim Ziyech netted from the penalty spot in the 55th minute during a dominant performance from the Premier League club.
Fourth round (2-1 vs. Plymouth Argyle)
Chelsea found Plymouth Argyle to be a much tougher proposition in the fourth round of the competition, with the Blues needing extra-time to record a 2-1 victory at Stamford Bridge.
Marcos Alonso then came up with the winning goal in the 106th minute, but Kepa Arrizabalaga needed to keep out an 118th-minute penalty from Ryan Hardie to allow Tuchel's side to progress to the next round.
Fifth round (2-3 vs. Luton Town)
In their first away match of this season's competition, Chelsea beat Championship outfit Luton Town 3-2 to progress to the quarter-finals.
In front of a crowd of little over 10,000, the Blues twice had to come from behind to level the scores at 2-2, with Saul Niguez and Werner on the scoresheet for the European champions.
Lukaku then netted the decisive goal in the 78th minute, converting after smart work from Werner to ensure that Chelsea would overcome their impressive opponents in the fifth round of the competition.
Quarter-finals (0-2 vs. Middlesbrough)
Having beaten Manchester United and Tottenham Hotspur in the fourth and fifth round respectively, Middlesbrough would have entered the clash with Chelsea full of confidence.
The Championship outfit found themselves 1-0 behind in the 15th minute through Lukaku, though, before Ziyech scored a second in the 31st minute to take the match away from the home side.
Boro had their moments in the second period, as they looked to pull themselves back into the contest, but it proved to be a comfortable progression to the semi-finals of the competition.
Semi-finals (2-0 vs. Crystal Palace)
Facing Premier League opposition for the first time in this season's competition, Chelsea recorded a 2-0 win over Crystal Palace to book their spot in the final.
Loftus-Cheek had benefited from an early injury to Mateo Kovacic to play a key role in the victory, and Palace were unable to come up with an answer in the latter stages, as Chelsea progressed to yet another final.
