This soup is pure comfort food. It's easy to prepare and reheats beautifully. If you don't have an emulsion blender, then you can purée the soup (in batches) in a food process or even a blender. Or, you can mix it with an electric hand mixer.
Melt the butter in a large pot over medium heat. Add the onion and celery and sauté until soft, stirring often, about 4 to 6 minutes.
4 tablespoon butter, 1 cup onion, 1 cup celery
Add the potatoes and stir to coat with the butter. Add the chicken broth and bring to a boil. Lower the heat to low and simmer for 25 minutes, or until the potatoes can easily be pierced with a sharp knife.
3 lbs russet potatoes, 5 cups chicken broth
Use an immersion blender to purée the potatoes. The mixture will be very thick. Stir in the milk, garlic powder, salt, and pepper. Simmer for another 5 to 10 minutes.
1 cup whole milk, 1 teaspoon garlic powder, 2½ teaspoon Kosher salt, 1 teaspoon black pepper
Serve hot garnished with crumbled bacon and snipped chives (if desired).
4 strips bacon

Notes
If you don't have an immersion blender, you can purée the potato mixture (very carefully and in batches) in a food processor or blender. Or, use an electric hand mixer. Or, if you prefer your soup to be chunky, just mash the potatoes with a masher or wooden spatula until you've reached the desired consistency.Leftovers are wonderful and can be reheated on the stove over medium heat. Store in an air-tight container in the fridge for up to 5 to 6 days. The soup can be frozen but won't be as silky once it has thawed and reheated.
