Place a trivet and steamer basket into the pressure cooker and add 1 1/2 cups water, squash, carrots, and onion. Close, seal, and set Instant Pot to manual HIGH pressure and cook for 10 minutes.
Natural release for 10 minutes, then release the remaining pressure.
Remove the lid and let sit for a few minutes before handling. (Remember, things are very hot!) Then, carefully remove trivet with squash, carrots, and onion on it. (Leave the water.)
Scoop squash flesh away from the skin with a spoon. (Compost the skin.)
Add squash, carrots, and onion back into Instant Pot along with all remaining ingredients including the leftover water from the steaming process.
Cook on low heat (with the lid off) for about 5 minutes.
Blend all of the ingredients with an immersion blender until well combined and smooth.
Serve with coconut milk drizzle and squash seeds on top.

Notes
Do you leave the skin on butternut squash for soup?Typically, the skin of butternut squash is removed before making soup because it can be tough and may not blend into a smooth consistency. However, if you roast or steam first, the skin can be easily scooped away from the softened flesh.Storage TipsStoring and reheating butternut squash soup is simple. Here are a few tips, though!
Fridge: You can keep this soup in an airtight container in the fridge for up to 5 days. (Using glass is usually the best option (think mason jar or glass tupperware.))
Freezer: I don’t recommend freezing this soup.
Reheating: To reheat your leftovers, add your soup to a saucepan, bring it to a simmer on medium heat, and stir occasionally. If you prefer, you can also reheat the soup in the microwave.
