Stoke remain in 10th position in the Premier League but missed the chance to close the gap on Newcastle above them as Mohamed Salah, Frank Lampard and Willian earned Chelsea a comfortable victory.
Having gone into the game on the back of three straight wins and only one defeat in nine, Hughes was disappointed his side did not make more of a game of it at Stamford Bridge.
"I was disappointed in what we produced," he said. "In recent weeks we've been a lot better than that.
"You have to come to places such as Stamford Bridge and make sure you put in a good performance as a team but we had too many who didn't hit their maximum today.
"In the end we weren't able to ask enough questions of a good Chelsea team
who, on the day, didn't really have to get out of second or third gear to take
the game away from us.
"We needed to make a better fist of it than we did. That's the disappointment
from our point of view."
Stoke host ninth-placed Newcastle at the Britannia Stadium in their next game.
