Velvety roasted pumpkin purée with warming spices, a touch of cream, and toasted pepitas on top. The soup that makes your whole house smell like October.
Roast pumpkin: Halve pumpkin and remove seeds. Brush with olive oil and roast cut-side down at 400°F for 30-35 minutes until very soft. Scoop flesh out and set aside.
Sauté aromatics: Melt butter in a large pot over medium heat. Add onion and cook 8 minutes until soft and translucent. Add garlic and spices, cook 1 minute until fragrant.
Build the soup: Add roasted pumpkin flesh and stock to the pot. Bring to a simmer and cook 10 minutes. Remove from heat.
Blend until velvety: Use an immersion blender (or transfer in batches to a blender) and blend completely smooth. Return to pot.
Finish with cream: Stir in heavy cream. Taste and adjust seasoning with salt, white pepper, and more spices if needed. Heat gently -- do not boil after adding cream.
Serve: Ladle into warm bowls. Swirl in extra cream, scatter pepitas, and add a drizzle of chili oil if desired.
