A velvety, smooth butternut squash soup made with just five simple ingredients in a slow cooker. This recipe requires minimal prep and delivers a rich, comforting texture that rivals restaurant-quality soups.

Ingredients

Scale
  • 1 large butternut squash (about 34 lbs), peeled, seeded, and cubed into 1-inch pieces
  • 1 medium yellow onion, diced
  • 4 cups vegetable or chicken broth (low-sodium recommended)
  • 2 tablespoons unsalted butter
  • ½ cup heavy cream
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon nutmeg (freshly grated if possible)
  • ½ teaspoon cinnamon

Instructions

  1. Wash the butternut squash, peel off the skin, cut in half, remove seeds, and cube the flesh into 1-inch pieces.
  2. Dice the yellow onion into small, even pieces.
  3. Add the cubed squash, diced onion, salt, pepper, nutmeg, cinnamon, and broth to the slow cooker pot. Stir gently to distribute spices.
  4. Cover and cook on Low for 4 to 6 hours until the squash is fork-tender. (Can cook on High for 2-3 hours if needed).
  5. Submerge an immersion blender in the pot and blend until the soup is completely smooth and silky. Scrape sides and blend again if necessary.
  6. Stir in the heavy cream, replace the lid, and let sit on Low for 5-10 minutes to heat through and thicken slightly.
  7. Taste and adjust salt if needed. Ladle into bowls and serve immediately, optionally garnished with extra cream, pepper, or pumpkin seeds.

Notes

For a dairy-free version, swap butter for olive oil and heavy cream for full-fat coconut milk. If using a countertop blender, let the soup cool slightly and vent the lid to avoid steam explosions. The soup tastes better the next day as flavors meld. It can be frozen for up to 3 months.
