Equipment

  • Stock pot (soup pot)
  • Immersion blender (or blender)
  • If freezing extras, freezer-safe storage containers

Ingredients

  • 3 large leeks (white and light green bulb portion only)
  • 2-2.5 pounds yellow or white potatoes
  • 1 cup celery, chopped (about 3-4 stalks)
  • 1/2 medium sweet yellow or white onion, chopped
  • 4 cups vegetable broth (low sodium, 1 quart container)
  • 1 cup water
  • 1 can coconut cream or coconut milk (approximately 12-14 ounces, sub heavy cream if desired)
  • 3 gloves garlic, peeled and roughly chopped
  • 3 Tbsp olive oil or butter
  • 2 Tbsp fresh sage leaves, chopped
  • 2 Tbsp fresh thyme (1.2 to 2 tsp dry)
  • 2 leaves bay
  • 1 tsp sea salt
  • black pepper, to taste
  • 3 Tbsp nutritional yeast (optional)
  • fresh chives or parsley chopped at serving time (optional)

Instructions

  • Wash leeks well to remove any hidden dirt. Thinly slice leeks, light green and white bulb portion only. (Save the green tops to dehydrate into powder! or, compost)
  • Add olive oil to large stock pot, and then add leeks along with chopped onion, garlic and celery.
  • Saute for 10-15 minutes, stirring occasionally until the onions and leeks soften and become semi-translucent.
  • Wash and cut potatoes into approximately 1 to 2 inch pieces. We don't bother peeling them, but suggest removing any scabs, blemishes, or especially tough skin portions.
  • Add the potatoes, fresh herbs, salt and pepper into the pot with the cooked leeks, garlic, onion and celery. Stir and let cook for 5-10 minutes, stirring occasionally.
  • Next, pour in the vegetable broth, water and coconut cream (or heavy dairy cream). Bring the soup to a boil and then reduce to a simmer. Continue to simmer until the potatoes are soft and falling apart, about 20 to 30 minutes. (Add optional nutritional yeast now too)
  • Use an immersion blender to blend the soup until your desired consistency is reached. Or, carefully transfer the soup into a blender and blend in batches as needed.
  • After blending, you could add a handful of chopped greens such as kale or bok choy and allow to continue to cook/soften, or add cooked beans. (We often add greens or other veggies but later, at the time of re-heating saved soup from the freezer.)
  • Serve your potato leek soup nice and warm, preferably alongside a slice of crusty homemade sourdough bread or fluffy focaccia. Top with optional chopped fresh chives or parsley.
  • Potato leek soup is good for up to a week stored in the refrigerator in an enclosed container, or a year in the freezer. We freeze in BPA-free quart containers. Allow it to cool before freezing. Defrost in the fridge and reheat on the stove.
