Peel the garlic and onion and chop finely.
Peel the potatoes and carrots, wash and cut into cubes.
In a frying pan, melt the butter and sauté the onion together with the garlic. Then add the potatoes together with the carrots and let them cook for about 4 minutes.
Add the water in which we dissolved the knorr cube and let it boil with the pan covered for 15 minutes.
With a spatula we take a little of the potatoes and carrots and set them aside.
The rest, with the help of a blender, reduce them to a cream-like composition. Add salt and pepper to taste.
Add sour cream and mix.
Place on a plate, add the potatoes and carrots set aside, sprinkle with grated cheese and serve hot soup.
