Author Notes: This soup started with the desire to make potato leek soup, but all I had on hand were sweet potatoes. It could very easily be vegan if you replaced the butter with a vegetable-based cooking fat (but man, do I love me some butter). - michael wilsker
Makes 2.5 quarts.
- 3 large leeks, cleaned and trimmed, halved, and sliced into 1/2" pieces.
- 3 sweet potatoes. peeled, cut into approx. 1/2" cubes
- 8 cups vegetable broth (chicken broth okay)
- 1 teaspoon dried basil
- 4 cloves of garlic, coarse chop.
- 1 dried bay leaf
- 1.5 tablespoons butter
- 1.5 tablespoons olive oil
- .5 teaspoons kosher salt
- 1/3 cup coconut milk
- In a heavy pot (I used a cast iron dutch oven), heat the butter over medium high heat until it melts and then bubbles. Add the olive oil and allow it to heat for approximately 10-15 seconds.
- Once the oil has heated, add the leeks and stir to coat with the butter/oil mixture. Stir in the salt. Saute the leeks, stirring occasionally until they're soft but not browning, approx. 10 minutes.
- Add the potatoes, the stock, the coconut milk, the basil and the bay leaf, stir, and bring to a boil. Once boiling, reduce heat and allow to simmer until the potatoes are cooked through, about 15 minutes.
- Remove the bay leaf. (it's much harder to do this step after you've blended the soup.)
- Once potatoes are cooked through, reduce heat to low, and, using an immersion blender, puree the soup until it's mostly smooth but with a slightly chunky texture.
- Continue simmering over medium heat until the soup thickens to your liking, at least 10 minutes is recommended (mine took about 30).
- Season with salt and fresh ground pepper to taste.
- Serve at your leisure. It goes well underneath a dollop of greek yogurt and finely chopped green onions.

Oops- I skipped a step: step 2a- After the leeks have reduced, add the garlic and mix it into the leeks. Allow the garlic to become fragrant, about 1-2 minutes, then continue to step 3.
