Peel the parsnips and cut them into large pieces. Cook in lightly salted water for 20 minutes.
Peel and finely chop the garlic and onion. Heat the oil in a medium saucepan and sauté the onion and garlic. Wash and drain the white beans. Put the beans and parsnips in the saucepan and heat briefly. Season with salt and pepper. Then finely puree the mixture in the pot with a hand blender.
Add milk (or cream) if you like and stir until the desired consistency is reached, for me that`s 150 ml. Season with broth, salt, pepper.
Goes well with meat and sauce, in principle everything that goes with mashed potatoes. Without the milk or with soy milk, the puree is of course vegan.
