Ingredients
- 1 large butternut squash (about 2.5-3 pounds), peeled, seeded, and cubed
- 2 tablespoons olive oil
- 1 medium yellow onion, diced
- 2 medium carrots, peeled and sliced
- 2 celery stalks, sliced
- 3 garlic cloves, minced
- 1 teaspoon salt (plus more to taste)
- 1/2 teaspoon freshly ground black pepper
- 1/2 teaspoon ground nutmeg
- 1/4 teaspoon ground cinnamon (optional)
- 4 cups low-sodium vegetable broth (or chicken broth)
- 1 cup water
- 1/2 cup full-fat coconut milk or heavy cream (for creaminess)
- 2 teaspoons maple syrup or honey (optional, for a touch of sweetness)
- Chopped fresh parsley, chives, or toasted pumpkin seeds (for garnish)
Instructions
- Prepare the squash: Carefully cut the ends off the butternut squash, peel it with a sharp vegetable peeler, slice it in half lengthwise, and scoop out the seeds. Cut the flesh into 1-inch cubes. (You should have about 6 cups of cubed squash.)
- Sauté the aromatics: In a large Dutch oven or heavy-bottomed soup pot, heat the olive oil over medium heat. Add the diced onion, carrots, and celery. Cook, stirring occasionally, until the onion is soft and translucent, about 6-8 minutes.
- Add garlic and spices: Stir in the minced garlic, salt, pepper, nutmeg, and cinnamon (if using). Cook for 1 minute, until fragrant.
- Add squash and liquids: Add the cubed butternut squash to the pot. Pour in the vegetable broth and water. Stir well to combine.
- Simmer: Bring the mixture to a boil over high heat, then reduce to a gentle simmer. Cover and cook for 25-30 minutes, or until the squash and vegetables are very tender and easily pierced with a fork.
- Blend the soup: Remove the pot from the heat. For a silky texture, use an immersion blender to puree the soup directly in the pot until completely smooth. Alternatively, let the soup cool slightly and blend in batches in a countertop blender (do not fill the blender more than halfway and vent the lid to avoid splatters).
- Add creaminess and adjust seasoning: Return the pureed soup to low heat. Stir in the coconut milk or heavy cream and maple syrup or honey (if using). Taste and adjust seasoning with more salt or pepper as needed.
- Serve: Ladle the soup into bowls. Garnish with chopped fresh herbs or pumpkin seeds for a bit of crunch. Serve hot, with crusty bread if desired.
Tips
- Substitutions: If you don’t have butternut squash, you can use other winter squashes like kabocha or acorn. Sweet potato also works well for a slightly different flavor.
- Make it vegan: Use coconut milk for creaminess and vegetable broth as listed. Skip honey in favor of maple syrup if sweetening.
- Peeling shortcut: Many stores sell pre-cut butternut squash. This saves time and effort—just use about 6 cups of cubes.
- Common mistake: Don’t skip sautéing the aromatics (onion, carrot, celery). This step builds the soup’s flavor foundation.
Serving Suggestions
This butternut squash soup is versatile and pairs beautifully with a range of dishes. Serve it as a starter for a festive holiday meal or as a main course on chilly evenings. For a heartier meal, offer it alongside:
- Crusty sourdough bread or warm baguette
- Grilled cheese sandwiches (try sharp cheddar or Gruyère)
- A simple green salad with vinaigrette
- Roasted chickpeas or croutons for crunch
- Toasted pumpkin seeds or a dollop of Greek yogurt on top
Variations
- Spicy butternut squash soup: Add 1/2 teaspoon of cayenne pepper or red pepper flakes with the other spices for a warming kick.
- Apple butternut squash soup: Add 1 peeled, chopped apple (such as Granny Smith or Honeycrisp) to the pot with the squash for a subtle fruity note.
- Curry butternut squash soup: Swap the nutmeg and cinnamon for 1 tablespoon of curry powder. Finish with a squeeze of lime for brightness.
- Roasted butternut squash soup: For even deeper flavor, roast the cubed squash on a baking sheet at 425°F (220°C) for 30 minutes before adding to the pot. This caramelizes the edges and intensifies sweetness.
- Protein boost: Stir in cooked white beans or red lentils for extra heartiness and nutrition.
- Herb finish: Blend in a handful of fresh sage or thyme leaves for an aromatic twist.
Storage and Reheating
Let the soup cool to room temperature before storing. Transfer to airtight containers and refrigerate for up to 4 days. To freeze, portion into freezer-safe containers or bags, leaving about an inch of space at the top for expansion. The soup will keep well in the freezer for up to 3 months.
Reheat refrigerated soup in a saucepan over medium-low heat, stirring occasionally, until hot (about 5-7 minutes). If the soup has thickened, add a splash of water or broth to loosen it. For frozen soup, thaw overnight in the refrigerator or gently reheat from frozen on the stovetop, covered, over low heat, stirring frequently.
Frequently Asked Questions
- Can I use frozen butternut squash?
- Yes, frozen cubed butternut squash is a convenient option and works well in this recipe. You can add it directly to the pot from frozen—no need to thaw. Keep in mind that frozen squash may cook a bit faster, so check for doneness after 20 minutes of simmering.
- Do I have to use cream or coconut milk?
- No, the soup is naturally creamy once blended, thanks to the starches in the squash. If you prefer a lighter soup, you can skip the cream or coconut milk entirely, or use a lower-fat milk. The soup will still be delicious, just a bit less rich.
- How can I make this soup ahead for a dinner party?
- This soup is ideal for making ahead. Prepare and blend the soup up to two days before your event. Store in the refrigerator, then reheat gently on the stove before serving. Stir in the cream or coconut milk just before serving for the freshest taste and texture.
- Is this soup gluten-free?
- Yes, as written, this butternut squash soup recipe is naturally gluten-free. Always check your broth and any garnishes to ensure they don’t contain hidden gluten sources.
- What’s the best way to peel and cut butternut squash?
- Start by cutting a thin slice off both ends so the squash can stand upright. Use a sharp vegetable peeler to remove the skin. Slice the squash in half lengthwise, scoop out the seeds, and cut into cubes. If the squash feels too hard to cut, microwave it for 2-3 minutes to soften slightly.
- Can I add other vegetables?
- Absolutely! Feel free to add parsnips, sweet potato, or even a handful of spinach or kale at the end of cooking. These additions can add depth and nutrition without overpowering the butternut squash’s flavor.
