Having the nature or quality of a dilettante; superficial, casual, or pursued without serious depth or commitment.
From dilettante plus the -ish suffix, meaning 'somewhat like' or 'having qualities of.' This is a variant form of 'dilettanteish,' both using the productive -ish suffix.
Both 'dilettantish' and 'dilettanteish' exist because English speakers couldn't agree on whether to attach -ish to 'dilettante' or 'dilettante'—language is a democracy where many spellings can coexist!
