The dog days of summer are upon us, oppressive and muggy. It seems the whole country is enveloped in a sweltering heat wave, the low hum of air conditioning white noise settling over the city like a droning fog. I'm really loving cold soups in this heat-- they fill my belly without making me break a sweat. Plus cool liquids just feel so good when every inch of you feels sticky and hot. We got a gorgeous bag of new potatoes in this week's CSA that were simply begging to be used creatively, so a vichyssoise seemed in order.
Now this soup is based on the idea of the vichyssoise-- a simple potato, leek and cream soup traditionally served cold. But a traditional vischyssoise is, of course, loaded with dairy and chicken stock. I decided to skip the leeks in favor of my CSA white onions and opted to make this recipe vegan. Because my homemade veggie stock is not the lovely pale yellow of a chicken stock, I threw tradition to the wind and browned the onions as well. The resulting color of the soup may not be as refined as the white-as-the-driven-snow version, but it makes up for a more rustic appearance with mouthfuls of deliciousness. If you would prefer your soup to be both white and vegan, I would suggest buying "no chicken" stock, using white pepper instead of black and sauteing your onions until just soft, not browned.
Cashew cream is shockingly easy to make and is just as creamy as traditional moo juice. This recipe makes way more than you'll need for soup swirling, so you'll have plenty extra to stir into your coffee or mix into your smoothies. If you're short on cashews or just really attached to your dairy, feel free to swirl in some heavy cream or creme fraiche instead.

PREP TIME: 15 minutes
COOKING TIME: about 30 minutes
MAKES: 4 one cup servings
INGREDIENTS:
for the soup:
- 2 cups 1" diced peeled potatoes (about 4-5 new potatoes)
- 8 cups veggie stock, divided
- 2 cups white onions, cut into 1" dice
- 1 tablespoon olive oil
- 1 large clove garlic, sliced
- sea salt & freshly cracked pepper, to taste
- 1/4 teaspoon ground nutmeg
- 1 sprig fresh rosemary, leaves removed from the stem
- 4-5 sprigs fresh thyme, leaves removed from the stems
for the Cashew Cream:
- 1 pound unroasted, unsalted cashews
- 3 cups water
- sea salt, to taste
- agave nectar, to taste
DIRECTIONS:
- Place cashews in a heat-proof bowl. Heat up 3 cups of water until boiling. Pour boiling water over cashews and cover bowl with a pot lid. Set aside.
- In a medium stock pot, place cut potatoes in 4 cups of veggie stock and bring to a boil. Add a pinch of salt and reduce heat to a simmer.
- While potatoes are cooking, heat up olive oil in a small skillet until the surface begins to shimmer. Add onions and saute until lightly browned. Add sliced garlic and saute for one minute more, taking care not to let garlic burn. Remove from heat and set aside.
- When potatoes are just soft, drain and discard liquid. Add potatoes, sauteed onion, garlic, nutmeg and 4 cups of fresh veggie stock back to the stock pot and bring to a simmer. Season with salt & pepper to taste and cook until potatoes are very soft. Remove from heat and add fresh rosemary and thyme.
- Working in batches, carefully blend soup until creamy. If it seems too thick, stream a little water through the top of the blender until desired consistency is reached. Keep in mind that the soup will thicken a little as it stands.
- Place soup in the fridge to cool down while you make the cashew cream.
- Place a strainer or a fine-meshed colander over a clean bowl. Line with damp cheesecloth.
- Working in batches, blend cashews with soaking water, adding agave nectar and sea salt to taste. If the mixture seems too thick, stream a little cool water through the top of the blender. Pour cashew mixture through cheesecloth and gently squeeze to release liquid into bowl. Repeat until all of the cashews have been blended and strained.
- Serve soup in chilled bowls, garnished with cashew cream.
