Ingredients Method Notes

Ingredients
  

  • 4 tbsp butter
  • 1 small onion, chopped
  • 3 cloves garlic, chopped
  • 4 lbs sweet potatoes, peeled and cubed
  • 4 cups chicken stock
  • 1 1/2 cups milk
  • pinch grated nutmeg
  • hot sauce to taste
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1-2 tsp truffle oil (optional)

Method
 

  1. Melt 4 tbsp butter in a dutch oven or other large pot over medium heat.
  2. Add 1 small chopped onion and sauté for about 5 minutes, until translucent.
  3. Add 3 cloves chopped garlic and sauté for another minute until fragrant.
  4. Add 4 lbs peeled and cubed sweet potatoes and 4 cups chicken stock to the pot.
  5. Increase heat to high and bring mixture to a boil.
  6. Decrease heat to medium, cover and simmer for 10 minutes, until sweet potatoes are very soft.
  7. Puree bisque until smooth either with an immersion blender or in batches in a blender.
  8. Stir in 1 1/2 cups milk, a pinch of nutmeg, 1 tsp salt, 1/2 tsp black pepper, and hot sauce to taste. Add truffle oil if desired.

Notes

– For an extra silky sweet potato bisque, pass the pureed soup through a fine-mesh sieve after blending.
– If you don’t have truffle oil, a swirl of extra virgin olive oil and a sprinkle of fresh thyme can add a lovely aromatic finish.
– Storage: Leftover bisque can be refrigerated in an airtight container for up to 3-4 days. For longer storage, freeze portions for up to 2 months. Reheat gently on the stovetop, adding a splash of milk or stock if it’s too thick.
– To ensure the sweet potatoes are perfectly tender for blending, listen for a gentle bubbling during simmering, not a vigorous boil, which can cause them to cook unevenly.
