Ranieri's side, who are now fourth in the table after their win at Carrow Road on Saturday, were on the wrong end of a 5-2 scoreline against Arsenal in their last Barclays Premier League outing.
But the Foxes bounced back and recorded their fourth win of the campaign as Jamie Vardy converted from the spot for his sixth goal in five league games before Jeff Schlupp netted his first of the season.
Ranieri's men even withstood a Norwich fightback after Congolese striker Dieumerci Mbokani pulled one back for the hosts.
The Italian manager said: "It was a very good answer after the defeat against Arsenal
It was a very good match against a good team that were well organised and play good football, but today we were very determined to win the match.
"We created a lot of great chances to score, we scored twice, then they scored and there was a big battle in English spirit and I love this kind of spirit."
Ranieri took the surprise decision to name five-goal Riyad Mahrez on the bench against the Canaries.
He explained: "We knew very well how Norwich would play
They push a lot on the flanks and make a lot of deliveries into the box.
"We wanted to start with a solid team and then, during the match, I could put Riyad on the field
But the match was different because we were winning.
"When you play against Norwich, they play good football and can score goals, so it was important for us to be calm, to play well and to be in a good position late in the game."
Leicester appeared on course to be cruising to victory after Schlupp's strike early in the second half.
But the introduction of Nathan Redmond and Mbokani helped breathe new life into the beleaguered hosts, with the latter netting after 68 minutes.
And Redmond, who was denied the chance to add to his tally of three goals this season after a fine save from Leicester goalkeeper Kasper Schmeichel in the closing stages, believes Norwich did enough to warrant a draw.
"I thought we were unlucky not to get a point as we were always in the game," Redmond told the club's website.
"Even looking at it from the bench before I came on we looked likely to pose a threat
We knew what they were capable of on the counter-attack because they're a good side, and they showed that.
"The goals set the tone for the game, although we kept creating chances and fought back in the final 30 minutes
We can't be too disheartened as we've not started the season badly.
"There are still a lot of games left and we've just got to keep going."
