Ingredients You'll Need

Ingredients needed to make four ingredient potato soup.

butter – the more butter the better! While I use unsalted butter and add salt later, use salted butter to save you the extra step.
onion — I use a small diced yellow onion but you can use a sweet onion, Spanish onion, or another variety of onion.
potatoes — I use russet potatoes for this potato soup recipe. Yukon potatoes are a great alternative.
water or stock — I use water to simmer my potatoes but if you want more flavour, simmering in a chicken or vegetable stock gives it a bump.
milk — I use full-fat dairy milk for the best flavour.
extras: if you have salt, pepper, and garlic powder, then that makes for a great addition to the potato soup.

How To Make This Potato Soup Recipe

In a pot over medium heat, melt 2 tablespoons of butter and saute the diced onions until they have softened about 3 to 5 minutes. Set it ahead on a plate for later.
Add the potatoes to the pot and fill with 4 cups of water. Bring to a boil then reduce to a simmer until the potatoes have cooked through, about 15 to 20 minutes.

Milk and onion added to a pot of potatoes.

Drain most of the water, leaving half a cup of liquid in the pot with the potatoes.
Add the milk and onions to the potatoes in the pot.

Butter, salt, and pepper added to blended soup then served.

Using an immersion blender, blend the soup until smooth. Add the rest of the butter and salt, pepper, and garlic powder as needed. Simmer and stir until everything is mixed together.
Serve as is or top with your favourite toppings.

Tips and Notes

My favourite toppings for potato soup are bacon crumbles, shredded cheese, and sour cream.
For a thicker soup, remove more of the water you boiled the potatoes in.
If you do not have an immersion blender, you can add everything to a regular blender. Just be careful of blending hot soup by making sure there's a way for the steam to release.
For extra flavour, I like adding some air fryer roaster garlic to the soup.

How do I store leftovers?

Leftover potato soup can be stored for up to 5 days in an airtight container in the fridge. I usually just reheat the soup on the stovetop.

Can I freeze this soup?

While others seem to have luck freezing potato soup, I don't usually freeze it since it's not recommended to freeze potato soup as it can change the texture.
