Instructions
Heat vegetable oil in a soup pot over high heat. Add chicken to hot oil; cook, stirring occasionally until browned, about 5 minutes.
Stir in 1/2 of the red onion and brown sugar. Cook until onions have softened and sugar starts to caramelize on the bottom of the pan, about 3 minutes. Stir in black pepper, cumin, and 1 teaspoon kosher salt. Toss in ginger and garlic; stir until sizzling, about 1 minute.
Add 4 cups chicken broth and stir to deglaze the bottom of the pot. Bring to a boil. Add coconut milk and curry paste. Add cayenne pepper and bay leaf. Stir in fish sauce. Reduce heat to medium-low and simmer, stirring occasionally, for 30 minutes.
Carefully cut squash with a large knife on a cutting board. Remove seeds and peel and discard skin. Cut flesh into bite-sized pieces. You should have about 1 1/2 pounds squash.
Add squash to soup and salt to taste. Add remaining chicken broth to cover squash. Simmer over medium-low heat, stirring occasionally, until pumpkin is just barely tender, 15 to 20 minutes.
Stir in remaining red onion, bell pepper, and green onions; cook for 2 minutes. Turn off the heat, and stir in 1/2 cup cilantro and 1/4 cup basil. Taste and adjust seasonings.
Ladle into bowls and garnish with more cilantro, basil, green onions, and serrano chiles. Squeeze lime juice into each bowl.
