Add the butternut squash, carrots, onion, apple, garlic, vegetable broth, cinnamon, nutmeg, salt, and pepper to the crock pot.
Cover and cook on Low for 6–8 hours or High for 3–4 hours, until the vegetables are tender.
Blend the soup with an immersion blender until smooth.
Stir in the heavy cream until well combined.
Cover and cook for an additional 15–20 minutes, until heated through.
Serve warm.
Notes
The cayenne pepper adds a spice to the soup, so if you do not like spice, I recommend leaving it out. I topped mine with some additional coconut milk and parsley.
