Fabregas has been sidelined for six weeks with a thigh strain, while Zouma has sat out the last nine months while recovering from an anterior cruciate ligament injury.
Both were back in training with their team-mates this week, and while they will not be risked against Everton, the first game after the break, at Middlesbrough on November 20, could see them return.
Blues boss Antonio Conte said: “Cesc and Kurt started to train with the team this week, and after the international break they will be available for selection.
“I'm pleased for Cesc, he's important for us. For kurt, played two games with U23s and will play another on Tuesday.”
Conte was, however, unmoved by rumours that Fabregas may be being lined up for a loan move come January.
He said: “It is the start of November, it's important to be in the present. Cesc is a chelsea player, and I'm happy to have him in my squad. It is important for him to come back with us and find the right form.”
Conte aso revealed that he has yet to speak to Jon Obi Mikel, who has not yet featured under the Italian, about his Chelsea future.
He added: “Mikel is working very well, very hard. I have not spoken with him, now is not the time.”
