Step 1

Heat the oil in a large soup pot over medium heat. Add in the garlic and onion, and saute until soft and fragrant, about 3 minutes. Add in the ginger and curry paste and stir to combine with the onion and garlic. Cook for 3 more minutes, stirring often. Add in the raw butternut squash cubes and slowly pour in the broth, stirring to combine. Season with salt and pepper. Bring to a boil and then reduce heat to a simmer and cover. Cook for 20 minutes, or until butternut squash is tender. Remove from heat and let cool for a few minutes.

Step 2

Add butternut squash, garlic, onion, ginger, Thai curry paste, broth, and salt and pepper to the slow cooker. Stir to evenly distribute. Cover and cook on low for 6-8 hours, or high for 3-4 hours.

Step 3

Pour the soup into a blender in batches and blend until smooth, or use an immersion blender to blend in the pot or slow cooker. Before serving, remove the soup from the heat or turn off the slow cooker and mix in the coconut milk (saving a few tablespoons to garnish) and lime juice (if using). Mix well. Season with additional salt and pepper, if desired, and add sriracha to taste for extra spice, if using. Pour into bowls and drizzle the remaining coconut milk on top. Swirl the coconut milk with a spoon. Sprinkle with chopped cilantro and chopped peanuts. Serve warm with naan bread.
