Mouthwatering Roasted Butternut Squash and Carrot Soup

I was well into my thirties before I realized that roasted vegetables make soup taste so much better than just boiling them. My mom always threw everything straight into a pot with some broth and called it a day. The soup was fine, but nothing special.

That’s because roasting brings out the natural sweetness in butternut squash and carrots—something you just can’t get from boiling. When you roast them first, they get those nice caramelized edges that add real depth to your soup. It takes an extra step, sure, but it’s the difference between okay soup and the kind that makes you go back for seconds.

What Kind of Butternut Squash Should I Use?

Any butternut squash you find at the grocery store will work great for this soup, but there are a few things to keep in mind when picking one out. Look for a squash that feels heavy for its size and has a tan, matte skin without any soft spots or green patches. The neck of the squash (the long, cylindrical part) contains the most flesh and fewer seeds, so a squash with a longer neck will give you more bang for your buck. If you’re short on time, many stores sell pre-cut butternut squash in the produce section, which can save you the hassle of peeling and chopping – just make sure the pieces look fresh and aren’t dried out around the edges.

Options for Substitutions

This cozy soup recipe is quite forgiving when it comes to swaps and substitutions:

• Butternut squash: You can easily swap butternut squash with other winter squashes like acorn, delicata, or kabocha. Sweet potatoes also work great and will give you a similar creamy texture.
• Coconut milk: If you don’t have coconut milk, heavy cream or half-and-half will work just fine. For a lighter option, try cashew cream or even whole milk, though the soup won’t be quite as rich.
• Vegetable broth: Chicken broth works perfectly if that’s what you have on hand. You can also use water with extra bouillon cubes, though the flavor won’t be as deep.
• Fresh sage: No fresh sage? Try dried sage (use about 1 teaspoon), fresh rosemary, or even fresh thyme. The flavor will be slightly different but still delicious.
• Dried ginger: Fresh ginger works great too – use about 1 tablespoon of minced fresh ginger instead of the dried version.
• Carrots: You can reduce the carrots and add more squash if needed, or try parsnips for a slightly different flavor profile.

Watch Out for These Mistakes While Cooking

The biggest mistake when making roasted butternut squash and carrot soup is not cutting your vegetables into similar-sized pieces, which leads to uneven cooking where some chunks are mushy while others remain hard. Make sure to roast your vegetables until they’re fork-tender and slightly caramelized around the edges – this usually takes 25-30 minutes at 400°F and creates the deep, sweet flavor that makes this soup special. Another common error is adding the coconut milk too early in the cooking process, which can cause it to curdle, so always stir it in at the end after you’ve blended the soup and removed it from high heat. For the smoothest texture, let the roasted vegetables cool slightly before blending, and blend in batches rather than overfilling your blender, which can create a chunky, uneven consistency.

What to Serve With Roasted Butternut Squash and Carrot Soup?

This creamy, warming soup pairs beautifully with crusty bread or dinner rolls that you can use to scoop up every spoonful. I love serving it alongside a simple arugula salad with toasted pumpkin seeds and a light vinaigrette to balance out the richness of the coconut milk. For a heartier meal, try it with a grilled cheese made with sharp cheddar or goat cheese, which complements the sweet, earthy flavors of the butternut squash and carrots. You can also top the soup with a dollop of Greek yogurt, some toasted nuts, or a drizzle of that reserved coconut milk for extra creaminess.

Storage Instructions

Refrigerate: This roasted butternut squash and carrot soup keeps really well in the fridge for up to 5 days in an airtight container. I actually think it tastes even better the next day because all those spices have more time to blend together. Just give it a good stir before serving since it might separate a little.

Freeze: You can definitely freeze this soup for up to 3 months in freezer-safe containers or bags. I like to freeze it in individual portions so I can just grab one whenever I want a cozy bowl. Just remember to leave some room at the top of your containers since it will expand when frozen.

Warm Up: To reheat from the fridge, just warm it gently on the stove over medium-low heat, stirring occasionally. From frozen, let it thaw overnight in the fridge first, then reheat the same way. You might need to add a splash of broth or water if it’s gotten too thick, and don’t forget to taste and adjust the seasoning if needed.

• Protein: 10-14 g
• Fat: 56-68 g
• Carbohydrates: 85-105 g

Ingredients

For the soup:

• 1/2 butternut squash, about 800 g (peeled and cubed into 1-inch pieces)
• 1 can coconut milk (full-fat preferred for creamier texture)
• 4 garlic cloves (whole, for easy removal after cooking)
• 700 g carrots, about 4 large (peeled and sliced into 1/4-inch rounds)
• 1 tsp turmeric
• 1 yellow onion (chopped into 1/2-inch pieces)
• 1 tsp dried ginger (freshly ground preferred for more flavor)
• 2 tbsp olive oil (or any neutral oil like canola)
• 1 tsp salt
• 1/4 tsp crushed red pepper flakes (optional, adds subtle heat and depth)
• 1 tsp dried thyme
• 3 cups vegetable broth
• 1/2 tsp ground black pepper

For the topping:

• Fresh sage leaves (roughly torn, about 8-10 leaves)
• 2 tbsp butter (I like Kerrygold unsalted butter for this)

Step 1: Prepare Vegetables and Season for Roasting

• 2 tbsp olive oil
• 1 yellow onion, chopped
• 1/2 butternut squash, cubed
• 700 g carrots, sliced
• 4 garlic cloves, whole
• 1 tsp salt
• 1/2 tsp ground black pepper
• 1 tsp dried ginger
• 1 tsp dried thyme
• 1 tsp turmeric
• 1/4 tsp crushed red pepper flakes

Peel and cube the butternut squash into 1-inch pieces, peel and slice the carrots into 1/4-inch rounds, chop the onion into 1/2-inch pieces, and leave the garlic cloves whole for easy removal later.

Place all vegetables on a baking sheet, drizzle generously with olive oil, and sprinkle with salt, black pepper, dried ginger, dried thyme, turmeric, and red pepper flakes.

Toss everything together until evenly coated—this coating is crucial for developing deep, caramelized flavors during roasting.

Step 2: Roast Vegetables Until Caramelized and Tender

• seasoned vegetables from Step 1

Preheat your oven to 200°C (400°F) and roast the seasoned vegetables for 30 minutes, stirring halfway through if needed.

The vegetables should be deeply golden and very tender when done—this roasting process concentrates their natural sweetness and creates the rich, complex flavor base of the soup.

I find that roasting vegetables first rather than boiling them creates a much more flavorful soup with better depth.

Step 3: Build the Soup Base

• roasted vegetables from Step 2
• 3 cups vegetable broth
• 1 can coconut milk

Transfer the roasted vegetables to a large pot, then add the vegetable broth and most of the coconut milk (reserve a small amount for garnish).

Bring the mixture to a gentle simmer and let it cook for 10 minutes to allow the flavors to meld together.

The garlic cloves will have softened considerably and will blend seamlessly into the final soup.

Step 4: Blend Soup to Smooth Consistency

• soup base from Step 3

Using an immersion blender, blend the soup directly in the pot until completely smooth and creamy.

For the smoothest texture, work the blender in slow, overlapping motions rather than holding it in one spot.

Taste the soup and adjust the seasoning with additional salt and pepper as needed—remember that the coconut milk will add slight sweetness, so season accordingly.

Step 5: Prepare Crispy Sage Garnish

• 2 tbsp butter
• Fresh sage leaves, roughly torn

While the soup blends, melt the butter in a small skillet over medium heat.

Once foaming, add the fresh sage leaves and cook for just 2-3 minutes until they become crispy and fragrant, being careful not to burn them.

The butter will brown slightly and impart a nutty flavor to the sage—I like to use quality butter like Kerrygold for this step since it really shines when cooked this way.

Step 6: Serve and Garnish

• blended soup from Step 4
• reserved coconut milk
• crispy sage from Step 5
• red pepper flakes for garnish

Ladle the smooth soup into bowls and drizzle each serving with a spoonful of the reserved coconut milk for richness and visual appeal.

Top with the crispy sage leaves and a light sprinkle of red pepper flakes if desired.

The contrast of the creamy soup with the crispy sage and the subtle heat creates a beautiful balance of textures and flavors.
