For the lowest carb count, confirm that your curry paste and chicken broth are free of added sugars, starches, and fruit juices. You can adjust the heat level by starting with less curry paste and adding more to taste. For a thicker, creamier texture without starch, let the soup simmer uncovered a bit longer to reduce slightly, or blend a small portion of the soup and stir it back in. This soup keeps well in the refrigerator for up to 4 days and can be frozen for up to 3 months; reheat gently over low to medium heat and avoid boiling hard so the coconut milk stays smooth.
