The main difference between pastiche and parody is that:

while pastiche is$,$ by definition, intertextual, parody is rarely intertextual.

while pastiche imitates another work, parody exaggerates certain features to make fun of it$.$

while pastiche tends to focus on work by celebrities and politicians, parody focuses on underground and subcultural works. while pastiche requires awareness of the work being imitated, parody does not.

while pastiche is a typically $21$ st$-$century form of intertextual reference, parody has roots in earlier eras.
