Roasted Butternut Squash Soup

An incredibly tasty roasted butternut squash soup

roasted butternut squash
Delicious and easy to make


At Clean Slate Farm we grow the Waltham variety of butternut squash, an heirloom variety that produces a lot of squash on each plant. If you have a four person family two plants would do just fine but for the two of us one plant provides all the squash we need, one plant giving us up to twelve big squash.

We’re never at a loss for what to do with our squash, but usually it ends up as roasted butternut squash soup in large enough batches that we can freeze it in two to three cup freezer bags for delicious dinners on cold winter nights. Those nights when you come in from barn chores and would kill for something warm. This recipe fits the bill. It’s an ever so slightly modified version of a soup I made when cooking at a Mobil 4 Star restaurant years ago.  It still never fails to bring me back to that kitchen and all the compliments the soup would bring from the dining room. Enjoy!

      Karen, I think I know you! Yes the soup does freeze very well. I make a pot and freeze it in two cup portions. We have several soups frozen this way. I just did a pot of Beef Barley…watch for that recipe soon.

          How does one ‘sweat’ onions, etc..? Just curious. What a delicious recipe.

          • reply Dave ,

            Sweating onions is a term used when you saute them. I think it is because the onions release water and start to go limp.
