When the air turns crisp and leaves begin to fall, nothing feels more comforting than a bowl of roasted butternut squash soup. The natural sweetness of squash intensifies when roasted, creating a caramelized depth that pairs beautifully with onions, garlic, and herbs.
Unlike quick stovetop versions, roasting the vegetables first adds complexity and richness, transforming a simple soup into something extraordinary. This creamy, velvety soup is not only delicious but also nutritious, making it perfect for cozy dinners, holiday starters, or weekly meal prep.
The secret to a rich, luxurious soup is caramelization. Roasting butternut squash (instead of just boiling) develops natural sugars and enhances flavor. Pair that with onions, garlic, and a touch of cream or coconut milk, and you get a silky, restaurant-quality soup at home.
For Roasting:
1 large butternut squash (about 3 lbs), peeled, seeded, and cubed
2 carrots, peeled and chopped
1 medium yellow onion, chopped

3 tablespoons olive oil

½ teaspoon black pepper
For the Soup Base:
4 cups vegetable or chicken broth
1 teaspoon fresh thyme (or ½ teaspoon dried)
½ teaspoon ground nutmeg
½ cup heavy cream or coconut milk (optional for extra creaminess)
