This spicy prawn and coconut noodle soup is a vibrant, fragrant dish that perfectly balances heat, acidity and creamy sweetness. By simmering a homemade spice paste with prawn shells and coconut milk, you create a deeply savoury broth that rivals your favourite Thai restaurant. The addition of meaty shiitake mushrooms and crunchy toasted peanuts provides a wonderful contrast in textures, making every spoonful a multi-layered experience of authentic Southeast Asian flavours.
As a high-protein meal, this nourishing soup is an excellent choice for a healthy midweek dinner or a restorative weekend lunch. The rice noodles make it a satisfyingly filling bowl, while the fresh lime juice and coriander ensure it remains light and zesty.

How to make Spicy Prawns and Coconut Noodle Soup with Shiitake Mushrooms
Place all ingredients in blender. Process until paste forms. Can be made 1 day ahead. Transfer to small bowl, cover, and chill.
Heat 2 tablespoons peanut oil in large pot over medium-high heat. Add prawns shells and cook until pink, stirring often, about 3 minutes. Add spice paste and half of onion; sauté until dry, about 3 minutes. Add fish sauce and sugar; stir until liquid is syrupy, about 2 minutes. Add coconut milk, broth, and mushroom stems. Bring just to boil, then reduce to medium-low, cover, and simmer 30 minutes. Strain soup into large pot, pressing on solids in strainer. Discard solids.
Meanwhile, place rice noodles in large heat-resistant bowl. Pour simmering water over to cover noodles; let stand at least 20 minutes to soften, stirring occasionally (noodles can stand in water up to 2 hours).
Heat remaining 1 tablespoon peanut oil in large nonstick skillet over medium heat. Add remaining onion and garlic; sauté until brown, stirring frequently, about 13 minutes. Add sesame oil, then sliced mushroom caps. Sauté until mushrooms are soft, about 4 minutes. Bring soup to simmer. Add mushroom mixture, prawns, peanuts, and lime juice to soup. Simmer until prawns is opaque, about 2 minutes.
Drain noodles; divide among 6 bowls. Ladle soup over noodles, dividing equally. Sprinkle soup with spring onions and coriander. Serve with lime wedges.
