Wash and clean the potatoes, leeks and carrots well. Cut everything into mouth-sized pieces and put them in a saucepan.
Cut the celery and also cut into mouth-sized pieces. Then add to the rest of the vegetables.
Now add 1.5 liters of water to the vegetables and mix with the vegetable broth. I heated the water in a kettle before doing this, so it goes a little faster. However, this is only optional.
Now simmer the soup for about 20 minutes until the vegetables are soft. Season to taste and enjoy. Bon appetite!
