Equipment

Ingredients

3 lbs. russet potatoes peeled, rinsed, and cut into 1-inch pieces
1 small onion chopped (about 1 cup)
4 tablespoon butter
2 cups milk 2% or whole milk is best
salt and pepper to taste

Instructions

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.
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 immersion 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.

Notes

We prefer using russet potatoes as they result in a creamier soup. You can use other variety.
2% or whole milk is best as the higher fat content make a creamier soup.
If you like a cheesy potato soup, you can stir 1 cup of cheddar cheese into the soup just before serving. Or try out different toppings like bacon, ham, sour cream, green onions and chives.
This soup can be stored in the refrigerator for up to 4 days. You can freeze for up to 3 months ( but we don't recommend as the texture may get a bit grainy).
