The Women's Super League (WSL) leaders, who qualified for the Conti Cup final last week, join Leicester City, Manchester United and Tottenham in the competition's final four. The semi-final draw will take place on March 12.
Chelsea beat Everton in their two WSL meetings this season by a 6-0 aggregate scoreline, but were frustrated on Sunday by the Merseyside club's defensive resolve for long periods.
With the exception of Nathalie Björn's header in the first half that hit the crossbar, opportunities remained scarce for Emma Hayes' team.
Everton created the best opportunities in the first half but Chelsea emerged with greater intensity after the break. They found the breakthrough thanks to Macario's clinical finish in the 65th minute before attacking deep to seal their place in the semi-finals.
With Sam Kerr's season-ending ACL injury in January, Macario's emergence comes at an opportune time for Chelsea, who remain in the hunt for an unprecedented quadruple.
Chelsea's next match will be against WSL title rivals Arsenal at Stamford Bridge on March 15.
