The former Arsenal and Chelsea winger joined Forest this summer from Ipswich Town.
After Hutchinson's performance in victory over Leeds, Dyche said: "I told him he’s got good people here. I said to him not to expect everything to click just like that.
“I told him to forget the price tag, it’s nothing for him to worry about. It’s just the modern industry.
“He is learning about playing in the Premier League. I told him he has got time and he has to keep doing what he has been doing - train well, work hard, look after yourself and enjoy it.
“He came on and I thought he was terrific. I’m very pleased for him - not just for us, I’m pleased for him, because it was important that.
“I don’t think he was left out of the Europa League squad, he wasn’t included. There is a difference between being left out and not being included. It was before my time.”
