Cook the pasta according to the instructions on the packet.
Dice the onions and finely chop or press the garlic, fry both.
Cut the pangasius into bite-sized pieces, add to the pan and fry briefly. Do not fry the fish all the way, otherwise it will be too dry. Deglaze with white wine, add the cream, add the second clove of garlic and simmer for about 7 minutes.
