Granny Smith apples add tartness that balances squash sweetness; swap for other tart varieties if preferred.
Immersion blender creates smooth texture; alternatively transfer cooled soup to stand blender in batches.
Coconut milk can be stirred in before serving or drizzled individually for creamier appearance.
Good to Know
Refrigerate in airtight container up to 4 days. Freeze up to 3 months; thaw overnight in refrigerator before reheating.
Prepare through blending step; cool and refrigerate. Stir in coconut milk just before serving.
Ladle into bowls; drizzle with coconut milk or swirl of extra virgin olive oil. Pair with crusty bread or grilled cheese sandwich.
Common Mistakes
Do not skip deseed step to avoid gritty texture in finished soup.
Do not over-blend if preferring chunky texture; pulse instead of continuous blending.
Do not add coconut milk before blending to prevent curdling during heat.

FAQ
Can I use regular blender instead of immersion blender?
Yes. Cool soup slightly, transfer in batches to blender, puree until smooth, then return to slow cooker. Work carefully with hot liquids.
What if my slow cooker cooks faster than stated?
Check doneness at 4 hours on low by piercing squash with fork. Overcooked squash breaks down into mush; pull earlier if texture becomes mushy before blending.
How long can I keep leftovers and can I freeze?
Store refrigerated up to 4 days in airtight container. Freezes well up to 3 months; thaw overnight in refrigerator and reheat gently on stovetop or in microwave.
