1 1/2 tablespoons extra-virgin olive oil
1 cup chopped onion
3 garlic cloves, minced
3 cups solid-pack pumpkin, canned
2 cups low-salt vegetable broth
2 teaspoons sugar
1/2 teaspoon ground allspice
1/2 teaspoon dried crushed red pepper
1 1/2 cups unsweetened coconut milk, divided
Salt and pepper
Pepitas, for garnish
Heat the oil in a heavy large pot over medium heat. Add the onion and garlic. Sauté until golden, about 10 minutes.
Add the pumpkin, broth, sugar, allspice, and crushed red pepper. Bring to a boil. Reduce the heat. Cover and simmer until flavors blend, about 30 minutes.
Working in batches, puree the soup in a blender until smooth. Return the soup to the pot. Bring the soup to a simmer, thinning it with coconut milk to the desired consistency. Season to taste with salt and pepper.
Ladle the soup into bowls. Sprinkle with the pepita seeds, drizzle with a teaspoon of coconut milk, and serve.
