In a medium Dutch oven melt the butter over medium heat. Add the leeks and onion and cook for about 10 minutes until the leeks ore softened, but not browned, stirring occasionally.
Add the broth, diced potatoes, bay leaf, salt and pepper. Increase the heat to high until the soup comes to a boil. Reduce the heat to low simmer and cook for 20 minutes or until the potatoes are cooked through and are fork tender.
Discard the bay leaf. Use an immersion blender or standing blender to blend the soup until smooth or desired consistency. Taste for seasoning and adjust as necessary.
Stir in the milk and garnish with parsley. Serve with a dollop of sour cream if preferred.
If you have lots of leftovers, you can keep the soup in the pot you made it in with a lid. Otherwise, transfer your leftovers to an airtight container. They'll last 2-3 days in the fridge.
Reheat in the microwave, or over medium heat on your stovetop.
