Ingredients and Substitutions

  • Extra virgin olive oil: This will be used for roasting the veggies for the soup.
  • Butternut squash: You will need 1 large butternut squash. If butternut squash isn’t available, try acorn squash, delicata squash, or even sweet potatoes. They’ll give you a similar creamy texture and sweet flavor profile.
  • Fresh herbs: This sheet pan butternut squash soup adds delicious fall flavor by using fresh sage and thyme.
  • Kefir: To make this soup extra creamy we will be using Lifeway Kefir, plain organic kefir. This adds in healthy fats and probiotics.
  • Bone broth: To add some much needed protein to the soup we use bone broth, this also helps to pack in vitamins and minerals as well. I use chicken bone broth, but beef bone broth works as well.
  • Aromatics. You will need 1 whole head of garlic and 1 medium yellow onion.

How to Make this Sheet Pan Butternut Squash Soup

Step 1

Roast the veggies. Preheat the oven to 425. Add a piece of parchment paper to a sheet pan then arrange the butternut squash, onion, and garlic on the pan, squash will be laying cut side up. Toss everything with olive oil and salt. Make sure it is all fully coated. Bake for about 45 minutes.

Step 2

Add in the fresh herbs. After the veggies are nicely roasted, add in the fresh sage and thyme. Bake for another 10 minutes or until the butternut squash is caramelized and easily pierced with a fork.

Step 3

Remove sheet pan and add veggies to stock pot. Once the veggies are done roasted, allow them to cool for about 5 minutes. Scoop the flesh from the butternut squash, squeeze out the roasted garlic cloves from the foil, and add them together with the roasted onions into a large stockpot. Pour in the bone broth and use an immersion blender to puree everything until smooth and creamy.

Step 4

Add the kefir. Heat the soup over low heat until warmed through. Stir in the kefir. Taste and adjust seasoning as needed. I like to add a bit more salt or a dash of black pepper at this stage to enhance the flavors.

Step 5

Serve and enjoy! Serve the soup warm and top with a drizzle of kefir and some more fresh herbs. I also love having some toasted bread with it.

Expert Tips

  • For the best sheet pan butternut squash soup, serve hot with fresh herbs, a kefir drizzle, and warm toasty bread.
  • Make sure to wait to add the herbs to the sheet pan until the last 10ish minutes of baking, if you add them too soon they will burn.
  • Cut the top off of the garlic, wrap the whole head with foil and a bit of olive oil. This is the best way to roast garlic. Roasting the cloves will make them hard.
  • If you are dairy free you can swap the kefir with canned full fat coconut milk.
  • Using bone broth adds protein, vitamins, and minerals to the soup, don’t skip out on this!
