The Italian side delivered a remarkable attacking display at the Stade Bollaert-Delelis, with Anastasios Douvikas scoring a hat-trick as Cesc Fàbregas' team recorded their third victory in four league-phase matches.
Como needed just seven minutes to open the scoring. Douvikas finished Máximo Perrone's assist to put the visitors ahead before doubling their advantage in the 32nd minute, converting another opportunity created by Álex Valle.
Nico Paz made it 3-0 in the 40th minute, finishing after receiving a pass from Douvikas to give Como a commanding advantage at half-time.
The visitors continued their dominance after the restart. Lucas Da Cunha scored in the 47th minute following an assist from Paz, while Marc-Oliver Kempf added the fifth six minutes later.
Douvikas completed his hat-trick in the 57th minute, with Paz providing another assist as Como continued to overwhelm the French side.
The scoring continued when Mattia Liberali made it 7-0 in the 62nd minute, finishing Jacobo Ramón's pass.
Lens eventually found a consolation goal in the 65th minute through Ruben Aguilar, who converted Florian Thauvin's assist.
However, Como were not finished. Martin Baturina restored their seven-goal advantage in the 69th minute after being set up by Liberali.
Substitute Matteo Papaccioli completed the extraordinary result in stoppage time, scoring in the 90th minute following another assist from Liberali to seal a 9-1 victory.
Como equal Champions League record
The emphatic victory saw Como equal the biggest winning margin in Champions League history, matching Liverpool's 8-0 victory over Besiktas and Real Madrid's 8-0 triumph against Malmö.
Como also became the first team since 1971 to score nine goals away from home in the European Cup.
The result continued their remarkable debut Champions League campaign, having previously recorded 4-1 victories over RB Leipzig and Manchester United.
They moved to fourth place in the league-phase standings with nine points from four matches and 19 goals scored.
Lens suffer historic humiliation
The defeat represented a disastrous night for Lens, who conceded nine goals at home and suffered the heaviest Champions League defeat by a French club.
Lens manager Yannick Cahuzac described the result as a feeling of humiliation, admitting that his team had been dominated throughout the encounter.
