Red Curry Sweet Potato Soup

Creamy, aromatic Thai-inspired soup with caramelized onions, fragrant curry paste, and silky coconut cream. The sweet potato provides natural sweetness balanced by spicy red curry and warming ginger. Serve as a comforting weeknight dinner or impressive starter for entertaining. This version builds depth through blooming curry paste in oil before adding stock, creating a more developed flavor base than simple dump-and-blend approaches.

Tips
Bloom curry paste in hot oil for 1-2 minutes before adding stock to deepen flavors and reduce raw paste taste.
For thicker soup, use less stock or reserve some chunks before blending. For thinner consistency, add stock gradually after blending.
Toast cumin seeds or add crispy shallots on top for textural contrast and extra depth.

FAQ
Can I make this dairy-free?
Yes. Use coconut cream as stated (already dairy-free) and swap chicken stock for vegetable stock. Ensure curry paste contains no fish sauce if strict vegan.
What if I don't have a hand blender?
Transfer cooled soup to food processor in batches, blend until smooth, then return to pot to reheat. Immersion blenders work best for single-pot cooking.
How long does this keep refrigerated?
Store in sealed containers up to 4 days. Reheat gently on stovetop. Freezes for 3 months; thaw overnight in fridge before reheating.
