There are main 4 parts to this quest, the first 3 parts require a team of 4 to 8 players to stand on tiles to open a portal to the minor boss, each minor boss will drop a heart. Once a player has all 3 hearts they can summon the final boss and complete the cooking quest.
When stepping on tiles many monsters will spawn, sometimes having a friend will help
