The easiest potato soup recipe I know is also the most delicious potato soup I know. Potatoes and chicken stock transform into some sort of alchemy in the pot and the chives give the whole thing a baked potato vibe, in the best sort of way.
1 1/2 pounds russet potatoes, peeled, cut into 2-inch pieces
4 cups chicken stock
1 cup whole milk
1 tablespoon butter
2 tablespoons chopped fresh chives
1/3 cup sour cream, plus more for serving
1. Combine potatoes and stock in a large pot. Cover and simmer until potatoes are very tender, stirring occasionally, about 45 minutes.
2. Puree potato mixture with an immersion blender, or, let cool and puree in batches in blender. Return soup to saucepan if using blender. Stir in milk, butter, and chives. Bring to simmer. Remove from heat and mix in 1/3 cup sour cream. Season with salt and pepper. Serve, garnishing with an additional dollop of sour cream.
