Last weekend's 1-0 win over Crystal Palace secured the Blues' first Premier League crown in five years.
It was the third league title Mourinho has overseen during two spells at Stamford Bridge and one secured with record-breaking dominance.
Chelsea will end the season on top for a 274th successive day, underlining the dominance and consistency the Portuguese's side have shown this term.
"It pleases me, the title, pleases me the way we did it and the consistency of being there from day one to the last day," he said, ahead of welcoming Liverpool to Stamford Bridge on Sunday.
"That is absolutely fantastic, to keep that stability, that strength keeping us there all the time.
"There were difficult periods, where we lost points, where we lost matches, periods where we lost players
We went through all these problems to go there from day one until the last day of the season.
"I am not counting the days, I am not trying to go for records
I just think for the boys to keep that stability also in their emotions - because it is very important to keep stable emotionally during the season - was fantastic.
"It was a title to remember, because of the title but also because of that stability from day one until the last day."
Such dominance means bookmakers have already made Chelsea favourite to win the title again next term, but Mourinho thinks it will be a tough ask to retain it.
"I think our rivals are very strong," the Portuguese said
"Next season they know what they want and we know what they want, too.
"But we also know what we want and they know what we want
I think it will again be a very important season."
