Add chopped broccoli, onion, garlic, and vegetable broth to the slow cooker. Season with salt and pepper.

Set on low heat for 4-6 hours or high heat for 2-3 hours until broccoli is tender.

Use an immersion blender or transfer batches to a regular blender until desired creaminess is achieved.

Stir in heavy cream (or coconut milk) into the blended soup.

Ladle into bowls and garnish as desired.
