The world number one powered to a brilliant 6-4, 6-4, 6-4 victory on Centre Court over the 39-year-old Djokovic, whose latest bid for a 25th Grand Slam hit a now familiar stumbling block.
"Amazing. It means a lot to me that I can play one more final here. It is the most special tournament we have," said Sinner.
Sinner has not dropped a set in the tournament since needing a decider to see off Miomir Kecmanovic in a rusty first-round showing after not playing a grass-court event in the build-up to Wimbledon for the first time.
The 24-year-old Italian will be favoured to retain the title when he faces French Open champion Zverev in his seventh major final, after winning his last nine meetings with the German world number three.
"I feel like today I had to raise my level, which I have done," added Sinner.
"I'm happy to be back in the final and of course we hope for a good final on Sunday."
Sinner has bounced back impressively in Southwest London over the past two weeks, after suffering a shock defeat - only his third of the year - in the French Open second round against unheralded Argentinian Juan Manuel Cerundolo.
There was a low-key opening to such a high-profile match, with a large portion of the crowd yet to retake their seats following home hero Arthur Fery's loss to Zverev in the other semi-final.
But Sinner was all business, breaking in the ninth game before serving out the first set.
Djokovic managed to stave off two break points in game five of the second set, but it was only short-lived relief for the seventh seed as Sinner broke for a 4-3 lead before two ruthless holds to love saw him move one set from the final.
Djokovic dropped serve again in the first game of the third set, leaving Sinner to ease to victory after just two hours and 20 minutes, saving the one break point he faced.
Sinner is targeting his fifth Grand Slam title, which would bring him within two of the tally of his great rival Carlos Alcaraz, currently sidelined by a wrist injury.
Djokovic was again hoping to break his tie with Margaret Court for the all-time record of most Grand Slam singles trophies.
He kept that dream alive with a remarkable five-and-a-quarter-hour win over Felix Auger-Aliassime in the longest-ever Wimbledon quarter-final earlier this week.
But the Serb did not have enough left in the tank to seriously push Sinner, who crushed 40 winners past Djokovic in a dominant performance.
"He was much better player on the court and was the dominant force," conceded Djokovic.
"You just have to hand it to him and say, 'Congrats, well done'."
Djokovic eyeing another tilt
Djokovic will be 40 by the time he has another chance to draw level with Roger Federer's record eight Wimbledon titles, but he is planning to be back for another tilt.
"I would like to, at least one more time," he said when asked if he would be back in 12 months' time.
His last Grand Slam title came at the 2023 US Open, since when he has lost six major semi-finals, four of them to Sinner.
Djokovic managed to get the better of Sinner, who is 15 years his junior, in the Australian Open last four earlier this year, but lost to Alcaraz in the final.
"What Novak is still doing is amazing. He is a true inspiration to the next generation," Sinner said.
"We always have very tough matches. The last one he won in the semis in Australia. I tried to make a couple of adjustments."
