The Foxes are sitting atop the League 1 table and are into round 3 of the FA Cup. It's the stability that he believes is helping the side along.
Pearson said: "We might make a few changes now and again, but the nucleus of our team has remained largely the same and that has helped us.
"It is nice to have a settled side but, when you have to make changes for whatever reason - injury or loss of form - it is still good to have people who will do a job.
"We have got a strong squad and it was nice to have (loan signing) Mark Davies in last week because he adds options in midfield.
"That is an important part of any team and it is good to have some more quality there."
The other side of the settled-team coin is having some players frustrated at lack of action, especially when it is difficult to contemplate changing a winning team.
Pearson said: "It is a big squad and only 11 players can start.
"But, of what you would deem to be our first-team squad, I think you would find that most have featured at some stage this season."
