Rinse black beans, and then add into the insert of the Instant pot along with the broth, onion, salt and garlic.
Set to manual function for 40 minutes. Ensure you’ve turned the knob to sealing.
Allow this to come to pressure and cook. Once this is done, allow for a natural release for 20 minutes.
You may see some liquid, please strain this into a small bowl - you don’t have to remove all of it. You’ll want to set it aside in case you need it later to achieve your desired consistency.
Next, add in the remaining ingredients and stir.
Use an immersion blender or potato masher to form the consistency you’d like. Again, you’re welcome to add back more of the reserve liquid.
