Do lentils need to be soaked?

No, unlike beans, lentils do not need to be soaked, which saves a significant amount of time.

Is it necessary to peel the butternut squash before boiling it?

Yes, because the skin of butternut squash may be quite rough, it is recommended to remove it before cooking. If you’re short on time, buy peeled and pre-cut butternut squash from the grocer.

How to Freeze Lentil Soup:

This soup with butternut squash, kale, and lentils is ideal for meal prep. It freezes beautifully, so keep it for a night when you don’t have time to prepare. Freeze the soup for up to three months in glass food containers or zip-locked bags put flat in the freezer.

Thaw the soup in the refrigerator overnight before reheating in the microwave or on the stove. If you fail to defrost the frozen soup the night before, you may microwave it in 30-second intervals, stirring in between.

Butternut Squash Lentil Soup Variations:

  • If you like, you can substitute sweet potato for the butternut squash.
  • If you can’t get Lacinato kale, also known as Tuscan kale, feel free to substitute curly kale. You may also substitute any leafy green, such as spinach or Swiss chard, for the kale.
