The Canucks scored two goals while losing their first two games but matched that quickly against the Kings. Hughes, a rookie defenseman selected No. 7 in the 2018 NHL Draft, made it 1-0 on a power play 5:26 into the first period, and Sutter scored 42 seconds later on a one-timer from the right face-off dot for a 2-0 lead.
"It's something I have been thinking about for a long time, just to get that one under my belt," said Hughes, who had three assists in his first five NHL games late last season. "I've told everyone from the start I'm going to try to get better every game. I feel really good right now."
Sutter made a nice spinning backhand pass to send Elias Pettersson in alone, and he beat Quick under the pad to make it 3-0 at 2:34 of the second period.
"It was nice to get the first one, to get that over," said Pettersson, who had two goals in the final 23 games last season. "To play a good game, spend a lot of time in the offensive zone, and create a lot of chances was first on my mind."
Toffoli scored on a breakaway at 7:28 to cut it to 3-1, but Miller scored his first goal with the Canucks at 14:44 to make it 4-1.
"The first period really set them on their heels," said Miller, who set an NHL career high with four points. "We continue to do a lot of good things. I don't want people thinking that we lost the first two games, it's a bad start. I think we felt really comfortable and confident after those games coming into this one. It's nice to see the pucks finally start to go in."
Walker scored at 6:51 of the third period to make it 4-2, but Hughes made a pretty pass off the rush that left Chris Tanev with a backdoor tap-in 40 seconds later to extend it to 5-2.
"I know they had a lot of energy right off the bat because it was their home opener and they had their whole ordeal with the captain and whatever, but we had chances to come back and then we just gave up a goal right after we scored a goal," Doughty said.
Alexander Edler (10:00), Josh Leivo (11:26) and Sutter (16:03) also scored in the third.
"I didn't like any of our game," Kings coach Todd McLellan said. "There's a lot of things that go into the game. There's the mind and then there's the skillset and then there's the systematic play and the ability to get involved in the right position, and I thought as the game wore on and it got away from us that just crumbled, so it tells me our group has a long, long way to go."
