Melt butter in a large soup pot over medium heat; stir in onion, celery and leek.
Reduce heat to low, cover and cook 20 minutes.
Serve with desired toppings. Recommended: real pork bacon, shredded cheese and green onions
Cook on high pressure for 15 minutes, and quick release the pressure (QR) when the cook time is complete. (Hint: I place a dish towel over the lever before releasing pressure to avoid starchy liquid from spraying everywhere.)
After the pressure is fully release, remove the lid, and carefully remove the bay leaves and thyme sprigs. Tongs are helpful for this.
