Hotshot Holt, 31, scored the winner against Arsenal on Saturday to help the Canaries to their first win this season.
Hughton said: "Grant's in great form and is always a threat. You can only judge him on goals and performances. He's now got three in three and he was excellent against Arsenal.
"Grant started very slowly last year and got the bulk of his goals after October.
"I'd like to think the goals he has scored of late can put him on a good run."
