Butternut Squash and Sweet Potato Soup
Ingredients
- 1 medium butternut squash peeled, seeded, and cut into 1-inch cubes
- 1 large sweet potato peeled and cut into 1-inch cubes
- 2 tbsp olive oil
- 1 large yellow onion finely chopped
- 2 cloves garlic minced
- 4 cups vegetable broth
- 1/2 cup heavy cream
- 1/2 tsp ground cinnamon
- 1/4 tsp ground nutmeg
- 1/2 tsp salt or to taste
- 1/4 tsp black pepper or to taste
Method
- Preheat your oven to 400°F (200°C) and line a large, rimmed baking sheet with parchment paper.
- Toss the cubed butternut squash and sweet potato with 1 tablespoon of olive oil and spread them in a single layer on the prepared baking sheet. Roast for 25-30 minutes, or until the vegetables are tender and caramelized at the edges.
- While the vegetables roast, heat the remaining 1 tablespoon of olive oil in a large Dutch oven or stockpot over medium heat. Add the chopped onion and cook for 5-7 minutes, stirring occasionally, until softened and translucent. Add the minced garlic and cook for 1 more minute until fragrant.
- Add the roasted squash and sweet potato to the pot along with the vegetable broth, cinnamon, nutmeg, salt, and pepper. Bring the mixture to a boil, then reduce the heat to low, cover, and simmer for 15 minutes to allow the flavors to meld.
- Carefully puree the soup using an immersion blender directly in the pot until completely smooth and creamy. Alternatively, work in batches to blend the soup in a stand blender, ensuring the lid is slightly ajar to allow steam to escape.
- Stir in the heavy cream and warm the soup through over low heat for 2-3 minutes. Taste and adjust seasoning with additional salt and pepper if desired before serving.

Common Soup Mistakes to Avoid
Even the simplest recipes can have little pitfalls, so let’s walk through them together to ensure your soup is perfect. The most common mistake is not roasting the vegetables long enough, which means they won’t blend into that smooth, velvety texture we want. You want those edges to be nicely caramelized for the deepest flavor.
Another error is adding the cream while the soup is boiling, as it can sometimes curdle. Always stir it in at the very end, just to warm it through. Finally, be sure to season generously, as root vegetables really soak up salt. For a fantastic recipe variation, this NYT Cooking Ginger Variation is a great resource.
