Put the pasta in a saucepan with plenty of salted water to taste and bring to the boil. Cook these according to the instructions, but cook about 2 minutes less, as indicated. Then drain / let drip and set aside.
Put the rapeseed oil and the bacon cubes in the mixing bowl, then set to 6 min / 100 C / counterclockwise rotation / mixing spoon so that it can steam. Then deglaze with water and cream and season with salt and gourmet pepper to taste. Add the corner of the cream cheese and set the whole thing again to 5 min / 100 C / counterclockwise rotation / mixing spoon to bring to the boil.
Again, preheat the oven to 200 degrees top / bottom heat. Pour the milk into a tall container, add the egg yolks and the previously grated Parmesan, stir. After boiling, add the stirred sauce and set the Thermomix again to 3 min / 80 C / counterclockwise / level 2 and let it simmer in it.
Now add the pasta to taste and mix well with the spatula. If necessary, grease a baking dish and add everything together. Sprinkle with the leftover Parmesan cheese.
