Start by peeling and dicing the potatoes and chopping the onion.

In a large pot, add the diced potatoes, chopped onion, and vegetable broth. Bring the mixture to a boil over medium-high heat.

Once boiling, reduce the heat and let it simmer for about 15 minutes, or until the potatoes are tender.

Using a potato masher, mash the soup to your desired consistency, or use an immersion blender for a smoother texture.

Stir in the milk, and season with salt and pepper to taste. Heat through.

Ladle the soup into bowls and garnish with fresh chives. Enjoy warm!
