Butternut Squash Soup with Toasted Cashews is a warm, comforting soup, full with the flavors of fall. I have a really good memory. Colors, smells and sounds sometimes bring a rush of memories and feelings at the most unexpected times.
All of a sudden I will be lost in the memory, like a time machine transporting me, back to a younger, more carefree time. I remember the first time I tasted Butternut Squash Soup with Toasted Cashews was Aspen, Christmas, 1991, at a restaurant called The Attic. It was the same restaurant we’d eat at every Christmas, but this night, as part of the prix fixe menu, I tasted Butternut Squash Soup. I could have stopped there, skipped the Prime Rib, the Yorkshire Pudding and the English Trifle.

“Please sir, another bowl of soup!” I still remember the mouth feel and texture of that soup the crunch of the cashews and the hint of nutmeg. I asked the waiter, who asked the chef, for the recipe. The young chef, flattered, came out to our table with a yellow legal pad and apologized for the vague ingredients and lack of directions, “My recipe serves 200”, he said. “That’s OK,” I told him. “I’ll figure it out if you give me the ingredients.”
I recreated that soup, and now it’s on my Autumn/Winter soup list every year. It’s rich, it’s elegant. Perfect for Thanksgiving or as part of a dinner party.
Well, I think all soups are simple…and way tastier than anything in a can. The original version was thickened with a roux (flour and butter), but I have found that if you reduce the amount of liquid, the squash will thicken the soup fine on it’s own. This also keeps it gluten free and lower in carbs. The original recipe also used heavy cream, which gives it richness and body…but I add just enough cream to bring it to the right consistency.
Making this butternut squash soup recipe
The original recipe required peeling, roasting and cubing a whole butternut squash which adds about an hour to the cooking time. And up until recently, this was the only way to make it. In the last few years, more and more stores are carrying pre-cubed butternut squash. While it’s more expensive, it’s certainly is more convenient. I’ve included directions for both methods.
Using a whole butternut squash
I’ve included this step in case you cannot find pre-packaged butternut squash or if you happen to be lucky enough to grow your own!
Peel the squash and then use an ice cream scoop to remove the seeds. Using a sharp knife or peeler, remove the outside skin. Cube the squash into 1″ pieces. I also use an ice cream scoop to clean out pumpkins for carving.
Making butternut squash soup vegetarian or vegan
The original recipe using chicken broth. To make it vegetarian, substitute vegetable broth. To make it vegan, swap the butter for more olive oil, use vegetable broth. Skip thinning with cream and add more vegetable broth or your favorite dairy substitute.
If using a blender to puree the soup, be careful not to fill the blender more than half way full. Cover lid with a tea towel and hold the lid down while blending. Here’s another blended soup, Leek and Potato, which is also perfect for cooler weather.
Making the “swirl”
You’ll need a squeeze bottle like this one, or a small jug with a fine spout. You’ll want to make the lines fairly thin.
Make a spiral, starting in the center.
Use a sharp object, like a skewer or toothpick and drag it through the cream.
Go first one direction, then the other until the desired look is achieved.
I think it looks like a fall leaf!
Top with toasted cashews and garnish with chopped thyme.
I hope you enjoy this delicious autumn soup recipe!
