Following a coaching role with Spurs, Hazard, who also played for Chelsea and Swindon, played a key role in heading up the youth development system at Crystal Palace.
Chigwell chairman Richard Slater said: "Ben and I will be speaking to Mickey on a week to week basis with regards to team selection, and what sessions he can take for us throughout the season.
"His football knowledge and coaching ability is by far the best I've seen at this level.
"It's amazing he wants to be involved with us and full credit goes to Ben Richman for making it happen."
