Disclosed is a method of preparing a vinyl cyanide compound-conjugated diene rubber-aromatic vinyl compound graft copolymer, a method of preparing a thermoplastic resin composition including the same, and a thermoplastic resin composition including the same. More specifically, when a conjugated diene compound and a molecular weight regulator are fed in a split manner during polymerization of conjugated diene rubber, and the content of an emulsifier is reduced, gel content may be reduced. In addition, when enlarged conjugated diene-based rubber latex is prepared by enlarging conjugated diene-based rubber latex using an acid enlarging agent, the enlarged conjugated diene-based rubber latex may have an expanded full width at half maximum in particle size distribution, thereby improving gloss, reflection haze, fluidity, and impact resistance. In addition, deposits may be reduced during injection molding.
