Add the oil, sliced onions, curry powder, salt and pepper to the bottom of a 6qt slow cooker and mix to combine.
Add the butternut squash, apples, water and apple cider on top and don’t stir. This will make the onions on the bottom caramelize during cooking.
Cook on low for 8 hours.
Using an immersion blender, blend until completely smooth. Season with salt and pepper to taste with a piece of crusty bread and enjoy while warm.
Freezing Instructions
Make the recipe as written, let cool completely to room temperature, then ladle into 1-cup or 2-cup Souper Cube trays. This makes it easy to defrost individual servings or specific number of servings at a time. Freezes well for up to 3 months.
Notes
