This Roasted Butternut Squash Soup Recipe Is Simple and Comforting

With holiday decorations filling stores and carols playing on the radio, it’s easy to forget that winter doesn’t officially arrive until December 21 in the Northern Hemisphere. If you’re not ready to transition into a new season just yet, make time for a classic fall recipe in between baking Christmas cookies. This comforting butternut squash soup from the Institute of Culinary Education is the perfect way to celebrate the last gasps of autumn.

This recipe uses just a handful of simple, traditional ingredients. Start by roasting a halved butternut squash in a 400º F oven for 35 minutes. As it cooks, sauté diced onion, carrot, and celery together with butter in a soup pot until soft and translucent. Scoop the roasted squash out of its peel and add the flesh to the pot with four cups of chicken stock. If you want to make the recipe vegetarian, use vegetable stock instead. Bring the mixture to a boil and then reduce it to a simmer for five minutes.

This recipe doesn’t require bold spices or rich ingredients to taste delicious. Roasting the butternut squash at high heat promotes the Maillard Reaction, and the browning and carmelization that happens in the oven creates a strong foundation of flavor in the soup.

“The butternut squash itself already gives lots of flavor,” ICE chef-instructor Chayanin Pornsriniyom tells Mental Floss. “So it’s actually a very effective and very easy recipe.”

To finish the soup, puree the vegetable mixture together using an immersion blender or Vitamix. Serve with creme fraiche and chopped chives on top. 

ICE offers courses in the culinary arts, pastry and baking arts, and hospitality and hotel management out of its campuses in Los Angeles and New York. If you’re interested in furthering your culinary education, view their curricula online.
