🥗 Ingredients

The Roast

  • 3 pounds Butternut Squash (peeled, seeded, and cut into 1-inch cubes)
  • 3 tablespoons Extra Virgin Olive Oil (for drizzling)
  • 1 teaspoon Kosher Salt (plus more to taste)
  • 1/2 teaspoon Black Pepper (freshly cracked)

The Soup Base

  • 4 tablespoons Unsalted Butter (high quality)
  • 1 large Yellow Onion (finely diced)
  • 2 medium Carrots (peeled and sliced)
  • 4 cloves Garlic (minced)
  • 1 tablespoon Fresh Sage Leaves (finely chopped)
  • 5 cups Vegetable or Chicken Stock (low sodium)
  • 1 tablespoon Maple Syrup (grade A dark)
  • 1/4 teaspoon Ground Nutmeg (preferably freshly grated)
  • 1/2 cup Heavy Cream (optional, for added richness)

For Garnish

  • 1/4 cup Toasted Pepitas (pumpkin seeds)
  • 2 tablespoons Crème Fraîche (for swirling)
  • 6-8 pieces Fresh Sage Leaves (fried in butter until crisp)

👨‍🍳 Instructions

  1. 1

    Preheat your oven to 400°F (200°C). Line a large rimmed baking sheet with parchment paper for easy cleanup.

  2. 2

    Toss the cubed butternut squash with olive oil, salt, and pepper directly on the baking sheet until every piece is well-coated.

  3. 3

    Spread the squash in a single layer and roast for 30-35 minutes, tossing halfway through, until the edges are golden brown and caramelized.

  4. 4

    While the squash roasts, place a large Dutch oven or heavy-bottomed pot over medium heat and add the butter.

  5. 5

    Once the butter melts and begins to foam, add the diced onion and carrots. Sauté for 8-10 minutes until the onions are translucent and starting to sweeten.

  6. 6

    Stir in the minced garlic and chopped sage. Cook for just 60 seconds until the aroma fills your kitchen, being careful not to burn the garlic.

  7. 7

    Carefully add the roasted butternut squash from the oven into the pot, scraping up any caramelized bits from the parchment paper.

  8. 8

    Pour in the stock, maple syrup, and nutmeg. Bring the mixture to a gentle boil, then reduce heat to low and simmer for 10-15 minutes to allow the flavors to marry.

  9. 9

    Remove the pot from the heat. Using an immersion blender, puree the soup until it is completely smooth and velvety. If using a standard blender, work in small batches and hold the lid down with a towel to prevent steam pressure buildup.

  10. 10

    Stir in the heavy cream (if using) and return the pot to low heat. Taste and adjust seasoning with additional salt or pepper as needed.

  11. 11

    For the garnish, quickly fry whole sage leaves in a small pan with a knob of butter until they turn dark green and crisp (about 30 seconds).

  12. 12

    Ladle the hot soup into warmed bowls. Finish with a swirl of crème fraîche, a sprinkle of toasted pepitas, and a crisp sage leaf.

💡 Chef's Tips

Roasting the squash is non-negotiable; it develops a depth of flavor that boiling simply cannot match. If the soup is too thick, add an extra splash of stock 1/4 cup at a time until you reach your desired consistency. For a vegan version, substitute the butter with coconut oil and the heavy cream with full-fat canned coconut milk. Always use fresh nutmeg if possible; the pre-ground version loses its volatile oils and aromatic punch very quickly. Don't skip the maple syrup—it doesn't make the soup 'sweet' but rather highlights the natural sugars in the squash.

🍽️ Serving Suggestions

Serve alongside a crusty sourdough baguette or grilled Gruyère cheese sandwiches for dipping. Pair with a crisp, dry white wine like a Chenin Blanc or a lightly oaked Chardonnay. A side salad of arugula, sliced apples, and toasted walnuts provides a refreshing, crunchy contrast. For a holiday starter, serve in small espresso cups as a 'soup shooter' topped with a tiny dollop of spiced cream. Pairs beautifully with roasted pork tenderloin or a simple roast chicken as a primary side dish.
