Inter arrived in Portugal’s capital on the back of a poor run of form after failing to win any of their past six games.
But they took advantage of a hesitant Benfica to take a firm hold of the tie.
Barella’s goal came after an excellent cross by Alessandro Bastoni, with the Italy midfielder heading it back across the keeper and into the net.
It was Inter’s first attempt on target but Benfica keeper Odisseas Vlachodimos prevented further damage by saving from former Manchester United and Arsenal player Henrikh Mkhitaryan.
This was Benfica’s 13th European game of the season after starting their Champions League campaign at the third qualifying round stage back in August.
But they did not create enough and face a mammoth task to turn the tie around after Lukaku wrapped up victory.
The Belgium forward had missed out on a starting place to 37-year-old Edin Dzeko but made an impact from the spot after beating the keeper for pace and power.
There was still time for Benfica to reduce the deficit but Goncalo Ramos’ 89th-minute attempt was kept out by Onana on a memorable night for Inter.
“We cannot think that we are already in the semi-final because we are not,” Onana said.
“We still need another great game like today’s next week. I said that we had to come here and play without fear because we could win – we did just that.”
