While most soups require time to develop flavor, this one comes together in a flash. Its bold spices, tender noodles and vegetables, and creamy broth will warm you to your toes! Smarts: This soup is highly adaptable. Use a different type of curry paste, other proteins, or swap in other quick-cooking vegetables for a more customized meal.
Heat a Dutch oven or deep pot over medium-high heat. Pour in coconut milk. Whisk in curry paste and sugar.
Stir in stock, fish sauce, tofu, and broccoli. Mix everything together, cover and bring to a boil.
Add zucchini and simmer, uncovered, until vegetables are crisp-tender, ~2 to 3 minutes more. Turn heat off and add lime juice. Taste and season with more fish sauce, sugar, curry paste, or lime juice if needed.
Divide noodles into serving bowls. Ladle soup over noodles and top with cilantro and hot sauce (if using). Enjoy!
