Butternut squash season is in full swing. So what better time to make a fall-themed recipe that features this fun gourd? Grab a big old spoon and scoop yourself some of this roasted butternut squash soup.

A while back I bought a whole batch of Williams Sonoma e-cookbooks. One of their series is the 365 recipe series where they have one recipe for every day of the year related to the general book topic. In their Soup of the Day book of the 365 series, the October 22nd recipe caught my attention.

It was a pretty basic squash soup recipe. It seemed like a good starting point. But I wanted a little bit more than what their recipe showed.

So, I souped up this recipe and added a little more complexity to the dish. More herbs, more flavor. And some notes on garnishing the soup to really bring it to its full potential.

Making a Pureed Soup

Butternut squash peeled and split in half ready to chop

Start off by roasting the squash alongside some other aromatics like garlic and onion. Then saute a bunch of herbs and spices in butter. The aromas wafting through your house will be mouthwatering.

Combine everything from the roasting pan with the sauteed herbs and spices. Then pour in some stock and bring it to a boil. Let everything simmer together for a bit. We want everything to be fully cooked so that it will blend up easier in the next step.

When everything has had time to cook together, it is time to puree.

For the smoothest soup possible, I recommend using a very powerful blender. Though I admittedly own 3 different blenders, I used the Vitamix to tackle this soup. In my experience, most stick blenders will not have enough power to make a super smooth soup. Also, make sure to blend your soup in batches so that you don’t overload the blender and create a mess.

Top and Serve Butternut Squash Soup

Though this soup is delicious all on its own, you can take it to the next level with some toppings.

After serving the soup into individual bowls, drizzle a little brown butter sage sauce or heavy whipping cream over the top. Or do like I did and add both into the same bowl.

Then add some shaved parmesan and toasted walnuts to the top of the soup. And if you’d like, gently place a few small sage leaves or sprigs of thyme on top for a fresh look.

To serve alongside your tasty soup, try making a simple grilled cheese sandwich with a sourdough loaf and some sharp cheddar cheese. Or serve it with some homemade rolls.
