Roasted Butternut Squash Soup

Diana Chistruga's avatarDiana Chistruga
This roasted butternut squash soup is the perfect cozy meal when you want something warm, creamy, and satisfying without spending hours in the kitchen. Roasting the vegetables first brings out their natural sweetness and adds deep, caramelized flavor, while roasted garlic, smoked paprika, and cinnamon give the soup extra depth. Butter and whole milk make it silky without heavy cream, and fresh lemon juice brightens every bite. It’s easy to make, great for meal prep, and even better with crusty bread on the side.

Equipment

  • Large baking sheet
  • Large pot or Dutch oven
  • Immersion blender
  • Chef’s knife
  • Cutting board

Ingredients
  

  • 1/2 medium butternut squash peeled, seeded, and cut into 1-inch cubes 
  • 1  large red bell pepper seeded and cut into chunks 
  • 1 medium yellow onion cut into wedges
  • 1 large carrot peeled and cut into chunks
  • 1 whole head garlic
  • 2 tbsp olive oil
  • 1 tsp kosher salt
  • 1/2 tsp freshly ground black pepper 
  • 1/4 tsp cinnamon
  • 1/4 tsp smoked paprika
  • 4 cups chicken or vegetable stock
  • 2 tbsp unsalted butter 
  • 1/4 - 1/2 cup whole milk
  • 1-2 tbsp fresh lemon juice or to taste

Instructions
 

  • Roast the vegetables
    Preheat the oven to 425°F (220°C).
    Arrange the butternut squash, red bell pepper, onion, and carrot on a large baking sheet. Drizzle with 2 tablespoons olive oil and season with salt, black pepper and smoked paprika. Toss well and spread the vegetables into an even layer.
    Cut the top off the garlic head to expose the cloves. Place it cut-side up directly on the baking sheet, without wrapping it in foil, and drizzle the exposed cloves with a little olive oil.
    Roast for 35–45 minutes, turning the vegetables once halfway through, until the squash is tender and the vegetables have deep golden-brown, caramelized edges. The garlic should be soft and golden. If the garlic starts browning too quickly, remove it from the oven while the vegetables finish roasting.
  • Combine the vegetables and stock
    Squeeze the roasted garlic cloves from their skins into a large pot. Add the roasted vegetables and stock.
    Bring to a gentle simmer and cook for 5 minutes.
  • Blend until smooth
    Use an immersion blender to purée the soup directly in the pot until completely smooth and silky.
    Alternatively, carefully blend the soup in batches in a high-speed blender, then return it to the pot.
    Add the butter and ¼ cup whole milk and blend again until smooth and velvety. Add more milk, a little at a time, if you prefer a thinner consistency.
  • Add 1 tablespoon fresh lemon juice, then taste and add more if needed. The lemon should brighten the soup and balance the sweetness and richness without making it taste distinctly lemony.
    Adjust the salt and black pepper to taste.
    • Recipe Tip
    Roast the vegetables until deeply caramelized, not just tender. Those browned edges concentrate the vegetables' natural sweetness and give the soup its rich, roasted flavor. The roasted garlic adds another layer of flavor, while butter and whole milk provide creaminess without the heaviness of heavy cream.
