Difficulty: Easy

Ingredients

1 butternut squash
2 tablespoons butter
1 yellow onion
2 cloves garlic
4 cups vegetable or chicken broth
2-3 tablespoons heavy cream or butter
to taste salt
to taste pepper

Step by step

Prep the squash. Cut butternut squash in half lengthwise. Scoop out seeds with a spoon. Place cut-side down on a rimmed baking sheet lined with parchment paper.
Roast the squash. Roast at 425°F for 40-50 minutes until flesh yields easily to a fork. The cut edges will caramelize slightly. Let cool for 10 minutes, then scoop flesh into a bowl with a large spoon.
Sauté aromatics. Heat 2 tablespoons butter in a large pot over medium heat. Add 1 diced yellow onion and cook until translucent, about 5 minutes. Add 2 minced garlic cloves and cook 30 seconds more.
Combine and simmer. Add roasted squash flesh and 4 cups vegetable or chicken broth. Bring to a gentle boil, then reduce heat and simmer 15 minutes to meld flavors.
Blend smooth. Use an immersion blender directly in the pot, or transfer in batches to a regular blender. Blend until completely smooth. Return to pot if using regular blender.
Season and finish. Season with salt and pepper to taste. Stir in 2-3 tablespoons heavy cream or butter for richness. Warm through and serve immediately.

Tips & troubleshooting

Choose squash that feels heavy for its size with unblemished skin
Pierce the skin a few times before roasting to prevent bursting
Save time by roasting squash a day ahead and refrigerating the flesh
Thin with additional broth if soup becomes too thick upon reheating
Freeze portions in mason jars leaving 2 inches headspace for expansion

Variations

Spiced Version. Add 1 teaspoon ground ginger, ½ teaspoon cinnamon, and pinch of nutmeg with the onions for warming spices
Apple Butternut. Roast 2 peeled, chopped Granny Smith apples alongside the squash for sweet-tart depth
Coconut Curry. Replace cream with coconut milk and add 1 tablespoon red curry paste when sautéing aromatics
Sage Brown Butter. Brown butter with fresh sage leaves until crispy, then drizzle over finished soup

Questions

Can I use pre-cut butternut squash?: Yes, but roast the pieces on a baking sheet at the same temperature. They'll cook faster, usually 25-30 minutes depending on size.
How do I know when the squash is done roasting?: The flesh should yield easily to a fork with no resistance, and the cut edges will have some caramelized browning.
Can I make this without cream?: Absolutely. The soup is naturally creamy from the squash. You can add a pat of butter for richness or leave it completely dairy-free.
How long does this soup keep?: Refrigerate up to 5 days or freeze up to 3 months. The texture stays smooth after thawing and reheating.
My soup is too thin. How do I thicken it?: Simmer uncovered for 10-15 minutes to reduce, or blend in a slice of stale bread or cooked potato for body.
