Wash, seed, and slice the pears into large chunks.
Add all ingredients to the Instant Pot liner. Set the valve to "sealing" and set to manual mode for 5 minutes at high pressure. Allow a natural release. Once the pressure is released, open the top using an oven mitt.
Using an immersion blender, blend the cooked pears to the desired pureed consistency. Feel free to leave it chunky (by using a potato masher) or make it smooth as shown in the photos. Serve the pear sauce warm or cold - as is with a spoon or use it to top oats!
Storage: Store in a sealed jar up to one week or freeze extra pear sauce in freezer safe containers for up to 3 months.
