Equipment
Method
- Heat the oven to 425°F.
- Toss the squash with the olive oil, 1/2 teaspoon of the salt, and the black pepper on a rimmed baking sheet.
- Spread the squash in a single layer.
- Roast for 30–35 minutes, turning once halfway, until tender and browned at the edges.
- Melt the butter in a 5-quart pot over medium heat.
- Add the onion and cook for 6–8 minutes, stirring occasionally, until softened.
- Add the sage and garlic and cook for 30 seconds, stirring, until fragrant.
- Add the roasted squash, broth, and remaining 1/2 teaspoon salt.
- Bring the soup to a simmer.
- Cook uncovered for 10 minutes.
- Blend the soup until completely smooth with an immersion blender, or carefully blend in batches in a countertop blender.
- Stir in the heavy cream and warm over low heat for 2–3 minutes without boiling.
Notes
For the smoothest soup, blend carefully in batches if using a countertop blender. Refrigerate leftovers for up to 4 days; freeze without the cream for up to 3 months, then add cream when reheating. For a dairy-free swap, use olive oil in place of butter and full-fat coconut milk instead of heavy cream.
