First bring water to a boil in a saucepan. Cook the pasta according to the instructions on the packet, drain and rinse. Then keep warm.
In the meantime, cut the onion into small pieces. Heat the oil in the pan and fry the onions until translucent. Add the cream and simmer the fresh rosemary in the cream for 5 - 10 minutes on a medium setting. Season with salt and pepper. If the sauce becomes too thick, it can be stretched with water and / or broth dissolved in water.
If you use rosemary on a stick, it can then be fished out again. The rosemary taste still comes through well. If desired, the plucked needles can also be stirred in.
Turn the hob down to the lowest setting. Now add the goat cream cheese and stir in. Mix the pasta with the sauce in the pan. Halve or quarter the cocktail tomatoes depending on their size and add them last.
