The commission is appointed in back-room deals by "elected" governments which are in turn often only indirectly appointed by parliaments. From your nickname I do infer you are from Germany, where ministers are not elected and the chancellor is not elected by the voters. Instead the chancellor is elected by the Bundestag, which was elected by the voters, but only after the usual back-room deals of forming a coalition. So there is no actual voter control on who becomes chancellor, as evidenced by several "grand" coalitions that always had Merkel as chancellor. Ministers are then not even elected by parliament, they are simply appointed by the chancellor. So not elected in any sense of the word, not even indirectly.
The only elected body in the EU is the EU parliament which has practically no powers when compared to the commission. It can only vote on what the commission proposes, it cannot make its own proposals. It cannot overrule the commission. And the commission can make rules and regulations of its own, without involving the parliament. The most the parliament can do is hold up the process a little.
The EU is not democratic by any sensible measure. "But there is an election somewhere in the process" doesn't make a democracy. Many dictatorships, communist regimes and even monarchies do have an election somewhere in the process. The emperor has no clothes, and the EU isn't democratic. Any timid initiative to make it so has died ages ago. The last straw was the trumped up non-election of von-der-Leyen. Actually, the parliament should have filled her job with its candidate, as was promised before the election. After election day, that promise which was intended to introduce at least a whiff of democratic accountability, was instantly forgotten. von der Leyen was instated instead of the parliaments candidate by a back-room deal.
