In a pot over medium heat, melt 2 tablespoons of butter and saute the diced onions until they have softened about 3 to 5 minutes. Set it ahead on a plate for later.
Add the potatoes to the pot and fill with 4 cups of water. Bring to a boil then reduce to a simmer until the potatoes have cooked through, about 15 to 20 minutes.
Drain most of the water, leaving half a cup of liquid in the pot with the potatoes.
Add the milk and onions to the potatoes in the pot.
Using an immersion blender, blend the soup until smooth. Add the rest of the butter and salt, pepper, and garlic powder as needed. Simmer and stir until everything is mixed together.
