Use the "Sauté" feature on your pot to sauté the onion in butter until onions are soft

Add in minced garlic and sauté for approximately 1 minute

Press the "Cancel" button on your pot and add in vegetable (or chicken) stock and potatoes. Stir the mixture until well combined.

Secure the lid on your post and set it using the "Manual" button to 30 minutes

Once the 30 minutes are up and the timer goes off, allow the pot to vent completely before removing the lid.

Stir in cream cheese until melted and then use a potato masher to mash the potatoes to achieve your desired consistency. I prefer to leave a few chunks in mine.

Season with salt and pepper and garnish with desired toppings.
