Equipment

Ingredients

For the soup

  • 1 large butternut squash approximately 3 pounds
  • 2 tablespoons olive oil
  • 1 medium yellow onion chopped
  • 2 carrots peeled and chopped
  • 2 cloves garlic minced
  • 4 cups vegetable or chicken broth
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon ground nutmeg
  • ½ teaspoon dried thyme
  • ¾ teaspoon kosher salt plus more to taste
  • ¼ teaspoon black pepper
  • ½ cup heavy cream
  • 1 tablespoon maple syrup optional

For the brown butter and crispy sage

  • 4 tablespoons unsalted butter
  • 10 to 12 fresh sage leaves

  • Pumpkin seeds
  • Crumbled goat cheese

  • Freshly ground black pepper
  • Crusty sourdough bread

Instructions

Instructions

  • Roast the squash
  • Preheat the oven to 400°F.
  • Carefully cut the butternut squash in half lengthwise and scoop out the seeds. Brush the cut sides with 1 tablespoon of olive oil and place the squash cut-side down on a parchment-lined baking sheet.
  • Roast for 40 to 50 minutes, or until the flesh is very tender and easily pierced with a fork.
  • Allow the squash to cool slightly, then scoop the flesh away from the skin.

Build the soup base

  • While the squash is roasting, heat the remaining tablespoon of olive oil in a large Dutch oven or heavy-bottomed pot over medium heat.
  • Add the onion and carrots. Cook for 8 to 10 minutes, stirring occasionally, until softened.
  • Add the garlic, cinnamon, nutmeg, thyme, salt, and pepper. Cook for approximately 30 seconds, just until fragrant.

Simmer

  • Add the roasted squash and broth to the pot.
  • Bring the mixture to a gentle boil, then reduce the heat and simmer uncovered for 15 to 20 minutes. The vegetables should be completely tender and the flavors well combined.

Blend until smooth

  • Remove the pot from the heat.
  • Using an immersion blender, blend the soup until completely smooth. You may also transfer the soup carefully to a countertop blender in batches. Never fill a blender completely with hot liquid, and allow steam to escape safely.
  • Return the soup to low heat.
  • Stir in the heavy cream. Add the maple syrup if you prefer a slightly sweeter finish.
  • Taste and adjust the salt, pepper, or broth as needed. Add a little more broth if you prefer a thinner consistency.

Make the brown butter and crispy sage

  • Melt the butter in a small skillet over medium heat.
  • Once melted, add the sage leaves. Cook until the leaves become crisp and the butter begins to smell nutty and turn golden brown, usually 3 to 5 minutes.
  • Watch it closely because browned butter can burn quickly.
  • Remove the skillet from the heat and add a small pinch of salt.

Serve

  • Spoon the soup into warm bowls.
  • Drizzle each serving with a little brown butter and top with crispy sage. Add toasted pecans, pumpkin seeds, goat cheese, cream, or black pepper as desired.
  • Serve immediately with warm bread.

    • What to Serve with Butternut Squash Soup

    This soup pairs beautifully with a simple salad made with mixed greens, sliced pears, toasted pecans, goat cheese, and a light vinaigrette.
    It also works well alongside:
    For a more substantial dinner, serve it as the first course before roasted chicken, pork tenderloin, or a savory tart.

  • How to Make It Ahead

    Prepare the soup through the blending step, but wait to add the cream until reheating.
    Store the cooled soup in an airtight container in the refrigerator for up to four days. Reheat it gently over medium-low heat, stirring occasionally, and then add the cream.
    The brown butter and sage are best prepared just before serving so the sage remains crisp.

  • Can You Freeze It?

    Yes. For the best texture, freeze the soup before adding the heavy cream.
    Allow the soup to cool completely, then transfer it to freezer-safe containers. Leave a little room for expansion and freeze for up to three months.
    Thaw overnight in the refrigerator, reheat gently, and stir in the cream before serving.

  • A Simple Fall Table

    One of the reasons I love this recipe is that it does not need a complicated table setting.
    I would serve it in creamy white bowls with brass or gold-toned flatware, simple linen napkins, and burgundy taper candles. Add a small arrangement of fading hydrangeas, magnolia leaves, or clipped branches from the yard.
    The table should feel warm and collected—not themed.
    Fall does not have to mean bright orange pumpkins covering every surface. Sometimes a bowl of golden soup, a worn wooden table, and candlelight are enough to make the season feel special.
