Chop your veggies: Peel and cube the butternut squash, quarter the onion, and peel the garlic cloves.
Load the slow cooker: Add olive oil, onion, garlic, veggie broth, coconut milk, spices, salt, and pepper. Stir everything together.
Let it cook: Cover and cook on low for 5–6 hours or on high for 3–4 hours, until the squash is fork-tender.
Blend it up: Use an immersion blender right in the slow cooker to blend until smooth and creamy.
Taste test: Adjust the seasoning if needed.
Serve and enjoy: Ladle into bowls, drizzle with a little extra coconut milk, and sprinkle with black pepper (or even fresh herbs if you’re feeling fancy).
