Potage Parmentier (Leek & Potato Soup)

An inexpensive French soul food with endless variations, this recipe provides a great way to learn the basic technique behind simple pureed soups. This same formula works well with a mix of vegetables. Replace half or all of the potatoes with broccoli or cauliflower or butternut squash, or try a mix of potatoes and parsnips. This recipe is easily doubled or tripled and freezes well. To make it vegetarian, omit the chicken stock. You can turn it into a vegan dish by using margarine in place of butter. If leeks aren’t available, you can use sweet onions. 

2 tablespoons butter
2 cups of leeks, thinly sliced (about 3 medium leeks)
1 lb. 
potatoes, peeled and diced  
2 quarts water, chicken or vegetable stock
Bay leaf and ½ teaspoon dried thyme
¼ cup whipping cream or 2 tablespoons softened 
butter 
Pinch of cayenne
3 tablespoons minced 
parsley, thyme or chives 

Prepare the leeks by discarding the root and the tough green upper stalks. Chop, then rinse in water to remove any residual dirt. In a four-quart or larger saucepan, sauté the leeks butter until softened and translucent, about five minutes. Add the potatoes, bay leaf, thyme and water or stock. Simmer for about 40 minutes until the vegetables are tender.

            Remove from heat. Discard the bay leaf. Break down the vegetables with a fork or a potato masher, or puree in a blender. Return to heat. Add the whipping cream of butter. Taste. Add more salt and pepper if you think it needs it, and a bit of cayenne if desired. Garnish with chopped parsley or herbs, and add a couple cranks of black pepper.

    This one is a huge hit in my household and is so easy to make. I also add thin sliced zucchini and various types of onions to “eat our fridge” as I recall Kathleen suggesting in KCCS. It’s a great low-sodium dish, and is also good served chunky though when pureed with a stick blender my kid forgets he’s eating vegetables.

    I just made this for my huge family over Thanksgiving – everyone loved it, even the really picky eaters under the age of five. We didn’t have any thyme or bay leaves, so I substituted wild mountain sage instead, but it still turned out very well. Thank you so much!
