Start by peeling and dicing the sweet potatoes, apple, and onion. The more even the sizes, the better your soup will cook.

In a large pot, heat the olive oil over medium heat. Add the chopped onions and sauté for about 3-5 minutes or until they turn translucent.

Add the diced sweet potatoes and apple to the pot. Stir well, and let it cook for another 5 minutes, allowing the flavors to meld.

Pour in the vegetable broth, ensuring everything is submerged. Bring the mixture to a boil, then reduce the heat and let it simmer for 15-20 minutes until the sweet potatoes are tender.

Using an immersion blender, puree the soup until it reaches your desired consistency. If you don’t have an immersion blender, you can transfer the soup in batches to a blender (be careful with hot liquids!).

Return the soup to low heat, and slowly stir in the sharp cheddar cheese until melted. Adjust the seasoning with salt, pepper, cinnamon, and nutmeg if desired.

Ladle into bowls, garnish with your favorite toppings, and enjoy your heartwarming Apple Cheddar Sweet Potato Soup!
