A rich, silky smooth soup made by roasting butternut squash to concentrate flavor, finished with nutty brown butter and fresh sage for a complex, comforting autumn meal.

Ingredients

Scale
  • 3–4 lbs butternut squash, peeled, seeded, and cut into 1-inch cubes
  • 6 tbsp unsalted butter
  • 1 large yellow onion, diced
  • 3 cloves garlic, minced
  • 4 cups vegetable or chicken broth (low-sodium)
  • 1/2 cup heavy cream (optional)
  • 6–8 fresh sage leaves
  • 1/4 tsp nutmeg
  • Salt and black pepper to taste
  • 2 tbsp olive oil (for roasting)

Instructions

  1. Preheat oven to 400°F (200°C). Peel the butternut squash, remove seeds, and cut into 1-inch cubes.
  2. Toss squash cubes with 2 tablespoons of olive oil, salt, and pepper. Spread in a single layer on baking sheets.
  3. Roast for 35-40 minutes, flipping halfway, until edges are dark brown and crispy.
  4. While squash roasts, melt 2 tablespoons of butter in a large pot over medium heat. Add diced onion and a pinch of salt; cook for 5 minutes until soft.
  5. Add minced garlic and cook for 1 minute until fragrant.
  6. Add roasted squash, pan juices, broth, sage leaves, and nutmeg to the pot. Bring to a boil, then reduce heat to low, cover, and simmer for 10 minutes.
  7. Remove from heat and discard woody sage stems. Use an immersion blender to puree soup until smooth.
  8. In a small saucepan, melt remaining 4 tablespoons of butter over medium-low heat. Stir constantly until milk solids turn golden brown and smell nutty (about 3-4 minutes).
  9. Stir brown butter into the soup. Add heavy cream if using. Taste and adjust seasoning with salt and pepper.
  10. Serve immediately with crusty bread or a drizzle of extra brown butter.

Notes

Roasting the squash is essential for flavor; boiling makes it watery. Brown butter should be watched closely to prevent burning. For freezing, omit cream and brown butter before freezing; add fresh upon reheating. If using a countertop blender, vent the lid to prevent steam explosions.
