How to Make Butternut Squash Soup: Step-by-Step Instructions:
Step 1: Prepare Your Oven and Vegetables
Preheat your oven to 350°F (175-180°C). While the oven heats, peel the butternut squash using a sturdy vegetable peeler. Cut the squash, onion, carrot and celery into uniform 1-inch (2cm) pieces. Consistent sizing ensures even roasting.
Step 2: Season and Roast
Spread all the diced vegetables on a large baking sheet in a single layer. Drizzle with oil and toss to coat evenly. Sprinkle with 1 teaspoon of salt and the garlic powder. Roast for approximately 35 minutes, or until the edges turn golden brown and caramelized. This roasting step is key to developing rich, deep flavour.
Step 3: Simmer the Soup
Transfer all roasted vegetables to your large stockpot. Add the remaining 1 teaspoon of salt, turmeric powder (if using), and pour in the broth until vegetables are covered. Place the pot over medium heat and bring to a gentle simmer. Let the soup simmer for 30 minutes to allow the flavours to meld together.
Step 4: Blend Until Smooth
Remove the pot from heat. Use an immersion blender directly in the pot to puree the soup until completely smooth and creamy. Alternatively, carefully transfer the soup in batches to a countertop blender, being cautious with the hot liquid. Blend until you achieve a silky, velvety texture.
Step 5: Serve and Enjoy
Ladle the hot soup into bowls. Optional garnishes include: a drizzle of cream, toasted pumpkin seeds, fresh herbs like cilantro, or a swirl of olive oil. Serve immediately with crusty bread.
Pro Tips for the Best Butternut Squash Soup
Choose the right squash: Look for butternut squash with a long neck and small bulb. The neck has more flesh and fewer seeds, giving you more usable squash.
Don't skip the roasting: This step makes all the difference. The caramelization adds natural sweetness and complexity you won't get from simply boiling.
Make it creamier: For an extra luxurious texture, add ½ cup of heavy cream, coconut milk, or cashew cream before serving.
Adjust consistency: If your soup is too thick, thin it with additional broth. If it's too thin, simmer uncovered for 10-15 minutes to reduce.
Season to taste: Always taste before serving and adjust salt, pepper, or add a squeeze of lemon juice to brighten the flavours.
Save Time: Frozen pre-cut squash and mirepoix (mix of pre-cut onions, celery and carrots) are often available in your grocery store freezer isle. Feel free to swap frozen pre-cut veggies, instead of fresh, saving time and sometimes money in the process.
Storage and Make-Ahead Instructions
Refrigerator: Store leftover butternut squash soup in an airtight container for up to 5 days. Reheat gently on the stovetop or in the microwave.
Freezer: This soup freezes beautifully for up to 3 months. Cool completely before freezing in portion-sized containers. Thaw overnight in the refrigerator and reheat on the stovetop or microwave oven.
Make-Ahead: You can roast the vegetables up to 2 days in advance. Store in the refrigerator and complete the remaining steps when ready to serve.
Variations and Substitutions
Instant Pot Method: Sauté diced vegetables in the Instant Pot using the sauté function, add broth, seal, and pressure cook on high for 10 minutes. Natural release for 10 minutes, then blend.
Slow Cooker: Place roasted vegetables and broth in slow cooker. Cook on low for 4-6 hours or high for 2-3 hours. Blend before serving.
Vegan Option: Use vegetable broth and coconut milk instead of cream. The soup is naturally vegan-friendly.
Spicy Version: Add ½ teaspoon cayenne pepper or red pepper flakes to the roasting vegetables, or garnish with hot sauce.
Thai-Inspired: Swap turmeric for curry powder and finish with coconut milk and fresh cilantro.
Apple Addition: Add one peeled, diced apple during roasting for extra sweetness.
Nutritional Benefits
Butternut squash is packed with vitamin A, vitamin C, potassium, and fiber. One serving provides over 100% of your daily vitamin A needs. The addition of turmeric adds anti-inflammatory properties, while keeping the recipe low in calories and naturally gluten-free.
What to Serve with Butternut Squash Soup

Frequently Asked Questions (FAQs)
Can I make butternut squash soup without roasting the vegetables?
Yes, you can skip the roasting step and simmer raw vegetables in broth for 30-40 minutes until tender, then blend. However, roasting develops deeper, caramelized flavours that give the soup a richer, more complex taste. The roasting step is highly recommended for the best results.
How do I easily peel and cut a butternut squash?
First, cut off both ends of the squash. Then, cut the squash right above the bulb. Stand each piece upright on the flat end and carefully slice down the sides with a sharp knife to remove the skin. Alternatively, poke holes in the squash, microwave for 2-3 minutes to soften the skin, which makes peeling much easier. Then cut in half lengthwise, scoop out seeds, and dice the flesh.
What type of broth works best for butternut squash soup?
Both chicken broth and vegetable broth work excellently. Chicken broth adds more depth and richness, while vegetable broth keeps the recipe vegetarian and vegan-friendly. You can also use bone broth for added nutrients or low-sodium broth if you want to control the salt content.
Can I freeze butternut squash soup?
Absolutely! Butternut squash soup freezes very well for up to 3 months. Let the soup cool completely, then transfer to freezer-safe containers leaving 1 inch (2cm) of space at the top for expansion. Thaw overnight in the refrigerator and reheat gently on the stovetop, adding a splash of broth if needed to adjust consistency.
How can I make this soup creamier?
To make the soup extra creamy, add ½ to 1 cup of heavy cream, half-and-half, coconut milk, or cashew cream just before serving. Alternatively, add a dollop of sour cream or Greek yogurt to each bowl. Blending the soup thoroughly until completely smooth also enhances the creamy texture.
Why is my butternut squash soup bitter?
Bitterness can come from overcooking the vegetables until they burn, using old or spoiled squash, or not adding enough salt to balance the flavours. Make sure to roast only until golden (not dark brown or black), use fresh squash, and season properly with salt. Adding a pinch of sugar can also balance the bitterness.
Can I add other vegetables to this recipe?
Yes! Carrots, sweet potatoes, parsnips, or regular potatoes work wonderfully in this soup. Keep the total vegetable quantity roughly the same to maintain the proper soup consistency.
How long does butternut squash soup last in the fridge?
Properly stored in an airtight container, butternut squash soup will last 4-5 days in the refrigerator. Reheat only the amount you plan to eat to maximize freshness.
What's the difference between butternut squash soup and pumpkin soup?
While both are winter squash soups, butternut squash has a sweeter, nuttier flavour and creamier texture compared to pumpkin. Butternut squash also has firmer flesh that's easier to peel and cut. The recipes are largely interchangeable, though cooking times may vary slightly.
Can I make this soup in an Instant Pot or slow cooker?
Yes! For Instant Pot: Sauté the vegetables (skip roasting), add broth, pressure cook on high for 10 minutes, natural release for 10 minutes, then blend. For slow cooker: Add all roasted vegetables and broth, cook on low for 4-6 hours, then blend. Both methods work well, though stovetop after roasting provides the deepest flavour.
Is butternut squash soup healthy?
Yes! Butternut squash soup is naturally low in calories, high in fiber, and packed with vitamins A and C, potassium, and antioxidants. It's naturally gluten-free and can easily be made vegan. One serving typically contains around 100-150 calories (without cream), making it an excellent choice for healthy eating.
What garnishes go well with butternut squash soup?
Popular garnishes include toasted pumpkin seeds (pepitas), a drizzle of cream or coconut milk, fresh herbs like cilantro, crispy bacon bits, croutons, a swirl of olive oil, roasted chickpeas, or a sprinkle of nutmeg or cinnamon. These add both visual appeal and complementary flavours.
