Cook the gnocchis according to the instructions on the packet - or take them out of the fridge.
Put the bacon and diced onion in a non-stick pan (small flame - possibly a little more oil). When the bacon is a little baked, add the gnocchis and brown a little to taste. Then grate the parmesan and sprinkle over it (coarser or finer, depending on your taste) and let it melt. Roughly paint the pepper over it, sprinkle with thyme (or other spices, if you like).
Finally, put the Gouda cheese in thick strips on top, briefly put the lid on so that it melts easily.
