The Nerazzurri secured a historic Champions League semi-final with AC Milan during a 3-3 during Inter vs Benfica, in a 5-3 aggregate at San Siro.
Simone Inzaghi's side will face local rival AC Milan in the last four thanks to goals from Nicolo Barella, Lautaro Martinez and Joaquin Correa which ensured straight-forward qualification.
Both Milan giants are trying to become the first Serie A side to win Europe's top club competition since Inter last lifted the trophy in 2010.
Martinez and Correa ended worrying goalscoring droughts with their strikes, as well as making sure that Fredrik Aursnes, Antonio Silva and Petar Musa netting for the away side made no difference to the outcome of the tie.
Silva and Musa netted late on for Roger Schmidt's team when Inter had already long made sure that they would be tussling Milan for a place in the June 10 final in Istanbul.
If there were any pre-match nerves among the sell-out San Siro crowd, they were soon eased as Inter immediately played like the team in two cup semi-finals rather than the one which has lost 11 times in Serie A.
Leading 2-0 from the first leg in Lisbon, Inter increased their aggregate lead following Nicolo Barella's sumptuous finish before a bullet header by Fredrik Aursnes gave Benfica hope.
Argentina World Cup winner Lautaro Martinez and substitute Joaquin Correa made it 5-1 on aggregate before Benfica scored two late goals through Antonio Silva and Petar Musa.
Inter have lost four of their past five games in Serie A to drop out of the Champions League places, but Simone Inzaghi's side can now look forward to two mouth-watering matches against AC Milan – who knocked out Napoli on Tuesday – for a place in the final.
The hosts looked to be cruising when Italy midfielder Barella made it 3-0 on aggregate after creating space for himself inside the box before producing a wonderful curling finish.
But Benfica were not done and Norway midfielder Aursnes kept the tie alive with a powerful header.
The damage from the first leg was too much, however, as Martinez prodded home Federico Dimarco's cross before Correa netted two minutes after coming on.
To their credit, Benfica kept going and Silva made it 3-2 on the night before substitute Musa equalised deep into stoppage time.
However, it was not enough to stop Inter from booking their place in the semi-finals for the first time since 2010 – when they won the competition under Jose Mourinho.
