  7. Add the shallots to the blender. Add 1 cup of water, parmesan, 1 teaspoon of salt, and ⅛ teaspoon of nutmeg and blend until smooth.

  8. Taste and add more salt if needed. If the sauce is too thick, thin it with a little more water.

  9. Pour the sauce into a small pot set over low heat.

  10. Mix in the sour cream and warm it through. Do not let the sauce boil.

  11. Fill a pot with water and salt (1 tablespoon of salt for every 2-quarts of water).

  16. Add a dollop of additional sauce and some parsley right when served on the table.

Recipe Notes

  • This butternut pasta sauce will work with any pasta, but spaghetti is an especially good pairing.
  • Be careful when cutting the squash, winter squash is hard. The best way to do it safely is to slice a bit off of both ends so that the squash can stand upright without it rolling. Then cut down the middle. See how to cut and peel a butternut squash for visuals, though note for this recipe you do not want to peel the squash before roasting.
  • It also helps to microwave the whole squash for 1 minute before cutting into it. This will lightly soften the outside of the squash, making it easier to cut it.
