  • Total Time: 45 minutes
  • Yield: 6 servings

Ingredients

Soup

  • 1 tablespoon olive oil
  • 1 medium onion, diced
  • 3 garlic cloves, minced
  • 1 tablespoon freshly grated ginger
  • 1 1/2 teaspoons ground cumin
  • 1 teaspoon ground cinnamon
  • 4 cups vegetable broth
  • 3 cups diced butternut squash
  • 1 cup split red lentils
  • 1 cup full fat coconut milk, plus more for serving if desired
  • Salt and pepper, to taste
  • 2 tablespoons fresh cilantro, chopped (optional)

Croutons

  • 3 cups bread cubes
  • 1 tablespoon olive oil
  • 1 teaspoon curry powder
  • 1/4 teaspoon garlic powder
  • Salt and pepper, to taste

Instructions

  1. Prepare the Soup Base: Heat 1 tablespoon of olive oil in a large pot over medium heat. Add the diced onion and sweat for about 5 minutes until soft and translucent, which develops the base flavor.
  2. Add Aromatics and Spices: Stir in minced garlic, freshly grated ginger, ground cumin, and ground cinnamon. Sauté while stirring constantly for 1 minute until fragrant. This step builds the aromatic depth of the soup.
  3. Add Main Ingredients and Simmer: Pour in 4 cups of vegetable broth, then add the diced butternut squash and split red lentils. Increase the heat to bring the mixture to a boil, then reduce to a simmer uncovered. Cook for 20–25 minutes until the lentils and squash become very tender.
  4. Blend the Soup: Remove the pot from heat. Use an immersion blender directly in the pot or transfer the soup in batches to a regular blender. Blend until the mixture is smooth and creamy.
  5. Finish the Soup: Return blended soup to the pot if needed. Stir in 1 cup of full fat coconut milk and season with salt and pepper to your taste. Reheat briefly if the soup has cooled during blending.
  6. Prepare the Croutons: Preheat oven to 400°F (204°C). In a large bowl, toss 3 cups of bread cubes with 1 tablespoon olive oil, 1 teaspoon curry powder, 1/4 teaspoon garlic powder, salt, and pepper until evenly coated.
  7. Bake Croutons: Spread the coated bread cubes on a baking sheet in a single layer. Bake for about 10 minutes or until they are lightly browned and crisp, turning halfway if needed.
  8. Serve: Ladle the hot soup into bowls. Optionally drizzle with additional coconut milk and sprinkle chopped fresh cilantro on top. Finish each bowl with a generous handful of warm curry-spiced croutons for added texture and flavor.

Notes

  • Note 1: Use fresh butternut squash peeled, seeded, and diced into roughly 1-inch cubes for the best texture and flavor.
  • Note 2: Adjust the seasoning after blending and adding coconut milk as flavors develop and mellow during cooking.
  • For a thinner soup, add additional vegetable broth until desired consistency is reached.
  • Red lentils cook quickly, so do not overcook to avoid mushiness beyond a creamy texture.
  • Croutons can be customized with other spices according to personal preference.
