'europäisch' and 'mitteleuropäisch' can both describe something from Europe. However, 'europäisch' is much more general and can refer to the whole continent or to the EU. 'mitteleuropäisch' means only Central Europe, that is, a specific region in Europe. The words can be confused if you only want to express that something is not outside Europe. If the central region of Europe is important, 'mitteleuropäisch' sounds more precise. If the region is not important or you are talking about Europe as a whole, 'europäisch' is more natural.
