KEY INGREDIENTS IN 4 INGREDIENT POTATO SOUP

Russet Potatoes - Any variety of potato will work but we found russet potatoes gave us the ideal creamy consistency and texture.

Onion - Use white or yellow onions in this recipe. Red onions may give your soup an unusual color.

Butter - Butter makes this soup creamy and delicious and we all know butter and potatoes go together like peas in a pod.

Milk - You can use any type of milk you like, but the more fat content, the creamier the soup.

Salt and Pepper - You will use salt and pepper as a finishing ingredient in this potato soup recipe. Season to taste.

HOW TO MAKE 4 INGREDIENT POTATO SOUP

Add prepared potatoes and onions to large stock pot or Dutch oven.

Add enough cold water to cover the potatoes.

Cook on medium-high heat until the potatoes are tender and fall apart when pierced with a fork.

Remove from the heat and drain most of the water, leaving about a cup of water in the pan. Add the butter and milk, and using a potato masher, mash the potatoes until they start to break down but not until they are all broken down.

Stir in the butter and milk, until everything is combined.

If you don't like any large chunks of potatoes in your potato soup, you can use an emersion blender.

Return the pot to the stove and cook for an additional 6-7 minutes on medium heat, stirring frequently.

If desired, season with salt and pepper to taste.

Remove from the heat and allow the soup to cool for 5-10 minutes before serving.

Feel free to top this soup with your favorite toppings. Some of our favorites are shredded cheddar cheese and sliced green onions.
