Peel the carrots, potatoes and celery root and cut into small pieces. Clean and wash the leek and cut into rings. Wash the cauliflower and cut into florets.
Peel and dice the onion and fry together with the minced meat in a large saucepan with hot oil. Add the carrots, potatoes, celery and leek, pour in the broth and let the stew simmer for about 1 hour. Add the cauliflower about 1/2 hour before the end of the cooking time. Season to taste with salt, pepper and marjoram.
Wash, pat dry and chop the parsley. Sprinkle over the stew just before serving.
My family also devoured baguettes with herb butter!
