Wash and sort spinach. Peel, wash and chop the potatoes. Peel and finely chop garlic and onion. Fry garlic and onion in hot oil. Put some spinach leaves aside, add remaining spinach, steam for 4 minutes, season with salt and pepper and take out.
Add potatoes and milk to the pot, cover and cook over medium heat for about 15 minutes. Add spinach again, puree everything and season to taste. Roast pine nuts in a dry pan until golden brown.
Pour the soup onto plates, spread the crème fraîche on top and allow to soak through a little. Garnish with pine nuts and spinach leaves.
