Here, you’ll find a reliable, classic recipe with plenty of tips, serving ideas, and creative variations to suit your taste and pantry.
Ingredients
- 2 tablespoons olive oil
- 1 large yellow onion, diced (about 1 1/2 cups)
- 2 cloves garlic, minced
- 1 medium butternut squash (about 2 1/2 lbs), peeled, seeded, and cubed (about 5 cups)
- 2 medium carrots, peeled and sliced
- 1 celery stalk, chopped
- 1 teaspoon kosher salt, plus more to taste
- 1/4 teaspoon black pepper
- 1/2 teaspoon ground cumin (optional)
- 1/2 teaspoon ground ginger (optional)
- 4 cups low-sodium vegetable broth (or chicken broth)
- 1 tablespoon maple syrup (optional, for added sweetness)
- 1/4 cup heavy cream or coconut milk (optional, for extra creaminess)
- Fresh herbs (thyme, parsley, or chives), for garnish
Instructions
- Prepare the vegetables: Peel, seed, and cube the butternut squash. Dice the onion, slice the carrots, and chop the celery.
- Sauté aromatics: In a large pot or Dutch oven, heat the olive oil over medium heat. Add the onion and sauté for 4-5 minutes until translucent and softened. Stir in the garlic and cook for 1 minute more, until fragrant.
- Add vegetables and season: Add the cubed butternut squash, carrots, and celery to the pot. Season with salt, pepper, cumin, and ginger (if using). Cook for 5-7 minutes, stirring occasionally, until the vegetables begin to soften slightly.
- Add broth and simmer: Pour in the vegetable broth. Bring to a boil, then reduce heat to low, cover, and simmer for 20-25 minutes, or until the squash and carrots are very tender and can be easily pierced with a fork.
- Blend the soup: Remove the pot from heat. Use an immersion blender to purée the soup directly in the pot until completely smooth. (Alternatively, let the soup cool slightly and carefully blend in batches in a countertop blender. Return to the pot.)
- Finish and adjust: Stir in maple syrup and cream or coconut milk, if using. Taste and adjust salt and pepper as needed. If the soup is too thick, add a little more broth or water to reach your desired consistency. Reheat gently if needed.
- Serve: Ladle the soup into bowls and garnish with fresh herbs. Add an extra swirl of cream or a sprinkle of cracked black pepper if desired.
Tips
- Substitutions: No butternut squash? Use peeled and cubed pumpkin, kabocha, or acorn squash. Sweet potatoes also work well for a similar texture and flavor.
- Make it vegan: Use vegetable broth and coconut milk or a plant-based creamer instead of heavy cream.
- Batch cooking: Double the recipe and freeze leftovers for quick future meals. The soup freezes beautifully and reheats well.
- Common mistake: Don’t rush the simmering step—undercooked squash won’t blend smoothly. Ensure the vegetables are soft before blending.
Serving Suggestions
This butternut squash soup pairs beautifully with crusty artisan bread, garlic toast, or a simple green salad for a complete meal. For a more substantial dinner, serve alongside a grilled cheese sandwich or a hearty grain salad. As a starter, drizzle the soup with a touch of herb oil or top with toasted pumpkin seeds (pepitas) for crunch and extra flavor. In the fall, try pairing with apple slices or a sharp cheddar for a sweet-savory contrast.
Variations
- Spiced Butternut Squash Soup: Add a pinch of cayenne pepper, smoked paprika, or curry powder during cooking for extra depth and warmth.
- Apple-Butternut Soup: Add 1 peeled, chopped apple (such as Granny Smith or Honeycrisp) with the squash for a subtle fruity note.
- Roasted Butternut Squash Soup: For more caramelized flavor, roast the cubed squash in a 425°F (220°C) oven for 25-30 minutes before adding to the pot. Proceed with the recipe as written.
- Thai-Inspired: Stir in 1 tablespoon red curry paste and finish with lime juice and fresh cilantro for a Southeast Asian twist.
- Protein Boost: Add a can of drained white beans or cooked red lentils before blending for a heartier, more filling soup.
Storage and Reheating
Allow the soup to cool to room temperature before transferring to airtight containers. Store in the refrigerator for up to 4 days. For longer storage, freeze the soup in individual portions for up to 3 months. Thaw overnight in the refrigerator before reheating. To reheat, warm gently in a saucepan over medium-low heat, stirring occasionally, until hot (about 5-10 minutes). If the soup has thickened during storage, add a splash of broth or water to loosen the consistency. Avoid boiling, as this can cause dairy-based soups to separate.
Frequently Asked Questions
- Do I have to peel butternut squash for soup?
Yes, the skin of butternut squash is quite tough and fibrous, so it’s best to peel it before cooking. A sharp vegetable peeler works well. If you’re roasting the squash first, you can scoop the flesh out of the skin after roasting instead. - Can I use frozen butternut squash?
Absolutely! Frozen pre-cubed butternut squash is a great time-saver and works perfectly in this recipe. Add it straight from the freezer and simmer until soft. - How do I make the soup thinner or thicker?
If your soup is too thick after blending, simply stir in more broth or water until it reaches your desired consistency. For a thicker soup, reduce the amount of broth or let the soup simmer uncovered for a few extra minutes before blending. - Can I make this soup in advance?
Yes, butternut squash soup actually improves in flavor after a day in the fridge. Make it up to 3 days ahead, cool completely, and store in airtight containers. Reheat gently before serving. - Is butternut squash soup healthy?
Yes! Butternut squash is rich in vitamins A and C, fiber, and antioxidants. The soup is naturally low in fat and calories, especially if you skip the cream or use a plant-based alternative. - What can I use instead of heavy cream?
For a dairy-free or lighter soup, use coconut milk, cashew cream, or simply leave out the cream and enjoy the soup’s natural creaminess from the blended squash and carrots.
