Heat the Canola Oil: Begin by heating 2 tablespoons of canola oil in a large pot over medium heat. Allow the oil to warm up until it shimmers, indicating it's hot enough to start cooking.
Fry the Onions: Add the chopped onion to the pot. Fry the onions, stirring occasionally, until they start to turn golden brown around the edges. This should take about 5-7 minutes. The browning process helps to develop a deep, rich flavor in the soup.
Add Butternut and Apples: Once the onions are nicely browned, add the cubed butternut squash and chopped apples to the pot. Cook for an additional 5 minutes, stirring frequently to prevent sticking and to ensure even cooking.
Add Ginger, Liquids Spices: Stir in the minced ginger, then pour in 3 cups of chicken stock and 1 cup of apple juice. Add 1/2 teaspoon of chili flakes and 1 cinnamon stock or 1 teaspoon of ground cinnamon. Season with salt and pepper to taste. Bring the mixture to a boil, then reduce the heat and let it simmer gently for 30 minutes. This allows the flavors to meld together and the vegetables to become tender.
Blend the Soup: After 30 minutes, check that the butternut squash and apples are soft. Add 2 tablespoons of quince jelly, which will add a subtle sweetness and help thicken the soup. Use an immersion blender to puree the soup directly in the pot until it’s smooth and velvety. If you don't have an immersion blender, carefully transfer the soup in batches to a countertop blender and blend until smooth, then return it to the pot.
Check the Seasoning: Taste the soup and adjust the seasoning with additional salt and pepper if needed.
Serve: Ladle the hot soup into bowls. For an extra touch of creaminess, add a dollop of Greek yogurt on top of each serving. This step is optional but highly recommended for its tangy contrast to the sweet and savory flavors of the soup.
Enjoy your delightful, warming butternut and apple soup, perfect for those crisp autumn and winter days!
