First sauté the finely chopped onion in a little hot oil until translucent, add the washed and sliced leek and cook at the same time. Wash and clean celeriac, carrots and zucchini. Coarsely grate and sauté in the same saucepan with onion and leek with a little water. Add bay leaves. Peel the potatoes, cut them into cubes and add them as well. Then add about 1 liter of water, depending on your taste. Let the vegetables and potatoes simmer until they are cooked through. Then mix in the cream cheese and season with salt, pepper and herbs to taste. Serve hot.
