Step-by-Step Instructions:

Step 1: Sauté Aromatics

  1. Heat the olive oil in a large pot over medium heat.
  2. Add the chopped onion, garlic, and ginger and sauté for 3-4 minutes until fragrant and the onion is translucent.

Step 2: Build the Broth

  1. Stir in the red curry paste and cook for 1-2 minutes to allow the flavors to bloom.
  2. Pour in the fish or vegetable broth and bring the mixture to a simmer.
  3. Add the coconut milk, fish sauce, and sliced red bell pepper and carrot. Let the soup simmer for 10 minutes to develop the flavors.

Serving and Storage Tips

Serving:

  • Pair the soup with jasmine rice or crusty bread for a heartier meal.
  • Top with a sprinkle of toasted coconut flakes for added texture and flavor.

Storage:

  • Refrigerator: Store in an airtight container for up to 3 days.
  • Freezer: The soup can be frozen for up to 2 months, but note that the texture of the fish may change slightly upon thawing. Let the soup cool completely before transferring to freezer-safe containers.
  • Reheating: Reheat gently on the stove over low heat, stirring occasionally.

Helpful Notes

  • Fish options: Firm white fish like halibut or mahi-mahi hold up well in this soup. For a budget-friendly option, tilapia works well too.
