Every year we prepare a barrel of fermented vegetables. This year we mixed red cabbage and carrots and spiced it with cumin seeds. Mostly, we prepare the fermented cabbage as a salad, but yesterday was just the perfect time to use it in a soup. The butternut squash soup recipe is extremely warming and fast to prepare, it takes only 10 minutes. Fermented vegetables are rich in probiotics and very handy for cold winter days when supplies of other fresh vegetables and salads are limited.

Creamy Butternut Squash Soup Recipe with Fermented Vegetables and Sourdough Sides
This is the best butternut squash soup I’ve made!
- Total Time: 15 mins

Ingredients
- 800 g peeled and chopped butternut squash
- 1 medium-sized broccoli

- 250 g fermented vegetables (red cabbage and carrots)
- dry herbs and spices (parsley, oregano, hot peppers)
- 1 heaping tablespoon of coconut oil or ghee
- 1 tablespoon of butter
Instructions
- Chop the butternut squash, put it into pot (water should just cover the squash) and cook it for 10 minutes until slightly tender.
- In the meantime, first slice the zucchini and chop the broccoli into tiny florets. Steam the broccoli for short time until intense green. Put aside.

Next, add your fermented cabbage, mix well and let it heat for a minute.

It takes approximately three weeks for a barrel of cabbage to ferment. We use a handmade oak barrel for fermentation and when it’s ready, we transfer it to big glass jars and put it in the fridge.
