Season the filet mignon with salt and pepper, then let it marinate in red wine for about 6 hours (while it works)
Drain
Top with butter and bake in a greased baking dish
Bake at moderate heat for 45 to 60 minutes
If too dry, moisten with a little of the wine it was marinating in
For the sauce, fry the onion in butter, then add the remaining ingredients
Stir well
Gradually add the red wine left over from the meat and cook, stirring, until it thickens slightly
If too thin, add a pinch of sugar
Optional: Add the sauce that formed in the baking dish where the meat cooked.
