Ingredients
1.2 kgbutternut squash
2 mediumonions
1 litervegetable broth
200 mlheavy cream
30 gbutter
0.5 teaspoonground nutmeg
1 teaspoonsea salt
0.25 teaspoonblack pepper
4 piecessage leaves
Instructions
1PREPARE THE SQUASH: Using a sharp knife and a sturdy cutting board, carefully cut the butternut squash in half lengthwise. Scoop out all seeds and stringy bits with a sturdy spoon, working methodically to ensure a clean cavity. Cut the squash into chunks approximately 8 centimeters in size, leaving the skin on for easier handling during roasting.
2ROAST THE SQUASH: Preheat your oven to 200°C (390°F). Toss the squash chunks with a light drizzle of olive oil, salt, and pepper. Spread them in a single layer on a baking sheet and roast for 35-40 minutes until the flesh is completely tender and caramelized at the edges, which deepens the natural sweetness. The skin should yield easily when pierced with a fork.
3SAUTÉ THE AROMATICS: While the squash roasts, heat the butter in a large heavy-bottomed pot over medium heat. Dice the onions into small, even pieces and add them to the melted butter, stirring frequently for 8-10 minutes until they become translucent and fragrant, releasing their natural sugars. Do not allow them to brown, as this would add bitterness to your final soup.
4COMBINE AND SIMMER: Once the squash is completely roasted and cool enough to handle, scoop the tender flesh away from the skin using a spoon. Add the roasted squash to the pot with the caramelized onions, then pour in the vegetable broth gradually, stirring to combine. Bring the mixture to a gentle simmer over medium heat and maintain this temperature for 10 minutes to allow flavors to meld, stirring occasionally.
5BLEND TO SILKY PERFECTION: Remove the pot from heat and allow the soup to cool slightly for about 5 minutes. Using an immersion blender, blend the soup in batches until completely smooth and velvety, or carefully transfer to a regular blender in portions. Work in batches if using a standard blender to avoid overfilling and ensure safety. The final consistency should be similar to heavy cream with no visible chunks.
6SEASON AND FINISH: Return the blended soup to the pot if necessary and warm it gently over low heat. Stir in the heavy cream slowly while whisking to incorporate smoothly. Season carefully with ground nutmeg, sea salt, and black pepper to taste, adjusting as needed. The nutmeg should be just detectable, providing warmth without overpowering the natural squash flavor.
7GARNISH AND SERVE: Ladle the hot soup into warmed bowls, leaving about 2 centimeters of space at the top. Tear the fresh sage leaves and scatter them over each portion for an elegant presentation and subtle herbaceous note. A light drizzle of cream in a decorative swirl and a sprinkle of cracked black pepper completes this restaurant-worthy presentation. Serve immediately while the soup is steaming hot.
