  • pounds buttercup squash
  • 2 tablespoons unsalted butter
  • 1 sweet onion (chopped)
  • 5-6 cups chicken stock
  • salt
  • pepper
  • nutmeg


  • Peel and seed the squash, then cut into 1-inch square chunks and set aside.
  • Add the butter to a large pot. Once the butter is melted, add the chopped onion and cook until translucent, about 10 min.
  • Add the squash and stir, then add 5 cups of stock.
  • Turn up the heat and bring everything to a low boil, then reduce the heat to low and simmer until the squash is tender. If the pan gets too dry while cooking, add another cup of stock.
  • Either transfer the soup to a food processor or use a stick blender right in the pan to purée the soup. Once smooth, season to taste with salt, pepper, and nutmeg.

If you can't find buttercup squash, you can substitute butternut squash or any other variety of winter squash.
