The European champions did not get out of second gear in the opening 45 minutes of their semi-final at a half-empty Nissan Stadium, Juan Mata's 11th goal of the season giving them the edge.
They came out flying for three minutes after the break, Fernando Torres scoring his fifth goal in eight days inside 20 seconds, with Darvin Chavez putting through his own net soon after.
Aldo de Negris did grab a stoppage-time consolation for Mexico's CONCACAF champions but Rafael Benitez's men barely broke sweat otherwise in a match that proved as one-sided as predicted and did not trouble the goalline technology being used in Yokohama either.
Mata opened the scoring when Monterrey gave away possession and Ashley Cole put the ball on a plate for the Spaniard to sidefoot home.
It took less than 20 seconds of the second half for Chelsea to double their advantage, the excellent Eden Hazard getting around the back before squaring for Torres to score via a huge deflection, the first time he had netted in three successive games since his £50million move from Liverpool.
Barely two minutes later and it was game over, Torres's brilliant low cross finding Mata, whose ball back across goal hit the unfortunate Chavez and trickled in.
Chelsea were rampant and Hazard weaved his way through but shot too close to Jonathan Orozco.
Di Nigris saw a shot deflected wide as Monterrey pushed for a consolation, which the striker got in stoppage time when he beat Cech from a narrow angle.
