Roasted Butternut Squash Soup

Roasted butternut squash soup is the bowl to make when the weather turns cool. Roasting the squash first brings out its natural sweetness and gives the soup a deeper, caramelized flavor than simply boiling it. Blended with sautéed onion, carrot, garlic, fresh thyme and sage, then finished with a splash of cream, it turns silky and rich. A spoonful of toasted pumpkin seeds, a drizzle of good olive oil and a pinch of smoked paprika on top make it feel special, and a slice of crusty bread on the side makes it dinner.

Why You’ll Like This Roasted Butternut Squash Soup

This is a from-scratch soup with simple ingredients and very little hands-on work. The oven does most of the job while you chop the aromatics, and a blender turns everything velvety in a minute. It is cozy enough for a family supper and pretty enough for guests.

• Deep flavor: roasted squash tastes sweeter and nuttier than boiled.
• Silky texture: blended smooth and finished with cream or coconut milk.
• Make-ahead friendly: keeps for days in the fridge and freezes beautifully.

Ingredients

For the Soup

• 1 butternut squash, about 3 lb, peeled, seeded and cut into 1-inch cubes
• 2 tbsp olive oil, divided, plus more for drizzling
• 1 tbsp butter
• 1 yellow onion, chopped
• 1 carrot, peeled and chopped
• 3 garlic cloves, minced
• 4 cups vegetable or chicken broth
• 1/2 cup heavy cream (or full-fat coconut milk)
• 1 tsp fresh thyme leaves, plus extra for garnish
• 4 to 5 fresh sage leaves, chopped
• 1/2 tsp smoked paprika, plus more for sprinkling
• Pinch of ground nutmeg
• 1 tsp salt, or to taste
• 1/2 tsp black pepper

For Serving

• 1/3 cup toasted pumpkin seeds
• Good olive oil, for drizzling
• Smoked paprika, for sprinkling
• Slices of crusty bread

You will need a large rimmed baking sheet, a large pot or Dutch oven, and an immersion blender or countertop blender. Serves 4 to 6.

Ingredient Notes

The squash: Choose a squash that feels heavy for its size with matte, unblemished skin. A sharp vegetable peeler removes the skin easily once you trim off both ends.

The broth: Vegetable broth keeps the soup vegetarian; chicken broth adds a little more savory depth. Low-sodium broth lets you control the salt.

The cream: Heavy cream gives a classic, velvety finish. Coconut milk makes the soup dairy-free with a faint sweetness that suits the squash.

The herbs: Fresh thyme and sage are worth it here. If you only have dried, use 1/2 teaspoon dried thyme and 1/4 teaspoon dried sage.

How to Make Roasted Butternut Squash Soup

Step by Step

1. Roast the squash. Heat the oven to 400°F (200°C). Toss the squash cubes with 1 tablespoon olive oil and a pinch of salt and pepper. Spread in a single layer on a rimmed baking sheet and roast 30 to 35 minutes, turning once, until fork-tender and browned at the edges.
2. Sauté the aromatics. While the squash roasts, warm the remaining 1 tablespoon olive oil and the butter in a large pot over medium heat. Add the onion and carrot and cook 6 to 8 minutes, stirring now and then, until soft and lightly golden.
3. Add garlic and herbs. Stir in the garlic, thyme, sage, smoked paprika and nutmeg. Cook 1 minute, until fragrant.
4. Simmer. Add the roasted squash and the broth. Bring to a boil, then lower the heat and simmer uncovered for 15 minutes so the flavors blend and the carrot is completely soft.
5. Blend. Turn off the heat. Purée with an immersion blender until completely smooth. If using a countertop blender, work in batches, fill it no more than halfway and vent the lid with a folded towel on top to let steam escape.
6. Finish with cream. Return the soup to low heat and stir in the cream. Taste and adjust the salt and pepper. If it is too thick, add a splash of broth or water; if too thin, simmer a few minutes longer.
7. Serve. Ladle into bowls and top with toasted pumpkin seeds, a drizzle of olive oil, a sprinkle of smoked paprika and a few thyme leaves. Serve with slices of crusty bread.

How to Toast Pumpkin Seeds

Place raw hulled pumpkin seeds in a dry skillet over medium heat. Stir often for 3 to 5 minutes, until they puff, turn lightly golden and start to pop. Tip them onto a plate, toss with a pinch of salt and a few drops of olive oil, and let them cool so they stay crunchy.

Tips for the Best Butternut Squash Soup

Give the Squash Space

Crowded cubes steam instead of roasting. Use two sheets if needed so every piece gets browned edges, which is where the best flavor comes from.

Cut Even Cubes

Pieces of the same size roast at the same rate, so nothing burns while the rest catches up.

Blend Longer Than You Think

An extra minute in the blender makes the soup noticeably silkier. For a perfectly smooth result, press it through a fine sieve.

Season at the End

Broth varies in saltiness, so taste after adding the cream and adjust then. A tiny squeeze of lemon juice can brighten a soup that tastes flat.

Variations

• Apple butternut: roast one peeled, chopped apple with the squash for a gentle fruity sweetness.
• Spiced version: add 1/2 teaspoon ground cumin and a pinch of cinnamon with the paprika.
• Vegan: use olive oil instead of butter, vegetable broth and coconut milk.
• Heat lover: add a pinch of chili flakes or cayenne with the garlic.
• Crunchy topping swap: use crispy sage leaves fried in olive oil or garlic croutons instead of pumpkin seeds.

Storage

Refrigerator: Cool the soup and store in an airtight container for up to 5 days. It often tastes even better the next day.

Freezing: For best texture, freeze before adding the cream. Freeze in portions for up to 3 months, thaw overnight in the fridge, then reheat and stir in the cream.

Reheating: Warm gently over medium-low heat, stirring often, and add a splash of broth if it has thickened.

Toppings: Keep toasted pumpkin seeds in a sealed jar at room temperature for up to 1 week so they stay crisp.

Frequently Asked Questions

Do I have to peel the squash before roasting?

For cubed roasting, yes. Alternatively, halve the squash, scoop out the seeds and roast it cut side down for 40 to 50 minutes, then scoop the soft flesh from the skin.

Can I use frozen butternut squash?

Yes. Roast the frozen cubes straight from the freezer, spreading them well apart, and add 10 to 15 minutes to the roasting time.

How can I make the soup thicker?

Use a little less broth, or simmer the blended soup uncovered for a few extra minutes until it reduces to the texture you like.

What goes well with butternut squash soup?

Crusty bread is the classic, but a grilled cheese sandwich, a green salad with apples and walnuts, or roasted chicken all make it a full meal.
