Roasted Vegetables: The Secret to Depth and Flavor

Roasting the butternut squash and sweet potatoes caramelizes their sugars and concentrates flavor, giving the soup a rich, slightly sweet base. The result is a silky, aromatic soup with a satisfying body.

Crafting the Perfect Butternut Soup

After the vegetables are roasted and pureed, a simple sauté of onion and garlic builds a savory foundation before you combine everything with stock and cream. Blend until smooth for a velvety texture.

Garnish ideas: Croutons, a dollop of sour cream or Greek yogurt, and fresh or dried thyme all add pleasing texture and flavor contrasts.

What You’ll Need

  • 1 medium butternut squash, 2–3 lbs (900–1350 g), peeled and cut into 1-inch pieces (about 4 ½ cups / 680 g)
  • 2 large sweet potatoes, peeled and chopped into 1-inch pieces (about 4–4 ½ cups / 680 g)
  • 2 tablespoons avocado oil or olive oil
  • ½ teaspoon ground turmeric
  • ½ teaspoon dried thyme
  • ¼ teaspoon ground cumin
  • ⅛ teaspoon ground nutmeg
  • 2 tablespoons (28 g) unsalted butter
  • 1 large onion, finely diced
  • 3 garlic cloves, minced
  • 4 cups (960 ml) vegetable broth or chicken broth
  • ½ cup (120 ml) heavy cream
  • Salt and pepper, to taste
  • Optional garnishes: sour cream, fresh or dried thyme, croutons

How to Make It

Roast the Vegetables:

  • Preheat the oven to 375°F (190°C) and grease a large baking sheet.
  • Arrange the butternut squash and sweet potato pieces on the baking sheet. Drizzle with oil and sprinkle with turmeric, thyme, cumin, and nutmeg.
  • Roast for 30–45 minutes, until the vegetables are soft and golden brown.
  • Transfer the roasted vegetables to a blender or use an immersion blender to puree until smooth.

Make the Soup:

  • In a large pot, melt the butter over medium heat. Add the onion and cook until soft and translucent. Stir in the garlic and cook 30 seconds to 1 minute.
  • Add the roasted vegetable puree and broth. Bring to a boil, then reduce heat and simmer for 10–15 minutes to let flavors meld.
  • Remove from heat, stir in the cream, and season with salt and pepper to taste.
  • For an extra-smooth texture, blend again with an immersion blender if desired. Serve hot with your preferred garnishes.
