After a 4-2 defeat at St Mary's last weekend, the Canaries returned to familiar surroundings and extended their unbeaten home run to six matches.
It was one-way traffic in the opening period and Norwich reaped their rewards in the 20th minute as Robert Snodgrass calmly slotted beyond Vito Mannone as the hosts took advantage of a faltering Sunderland defence.
The Canaries' advantage was doubled on the half-hour as Alex Tettey produced a thunderous volley as Norwich appeared to have all but sealed the points before the break.
Hughton was impressed by his side's display in the opening exchanges but was even quicker to praise Norwich for maintaining their standards throughout.
"We were very good in the first half, got the goals that we need but you knew that a Sunderland team fighting for their lives as well would give us a lot of problems in the second half," he told Sky Sports.
"We managed to maintain it for it 90 minutes and I thought we were good enough to perhaps get another goal, another two maybe which would have helped our goal difference.
"But I'm really delighted with the performance from start to finish."
Norwich were on the wrong end of a 4-2 defeat on the south coast last weekend but Hughton defended his players, claiming they were beaten by the better side on the day.
"We weren't good enough last week and that's not down to individuals, it's down to the day," he added.
"You have days where you come out second best and if that's the case you just hope you can make it a tight enough game."
Despite struggling on the road, Norwich are now unbeaten in their last six home fixtures and Hughton believes the support of the Canaries faithful is proving vital as they edge closer to safety.
"We've been good here at Carrow Road; we have a crowd that get behind us but we know that we've got to give them something to shout about.
"I thought we were excellent today, but to maintain that for 90 minutes I thought was excellent."
Victory elevated Norwich to 13th in the Premier League standings, seven points clear of the relegation zone.
