Grandmother’s Potato Soup Recipe

My Grandmother’s Potato Soup Recipe makes an old-fashioned, easy, comforting soup recipe. Made with 5 ingredients and no heavy cream! Instant Pot instructions included.
Soup always makes one of my favorite meals. Like our favorite vegetable soup and chicken and dumplings, this is one of the soups that I grew up loving the most. Before there was such a thing as loading a potato soup with bacon, cheese, and onions, my Grandmother Verdie made her potato soup very simply – with potatoes, milk, butter, and salt and pepper. If my sister Wendy and I knew that Grandmother made this soup for supper, we’d beg to be able to eat supper with her. With one bite, it is so easy to understand why!
The Best Potato Soup Recipe
You could add all sorts of things to this soup if you’d like, but I recommend starting with this simple, basic recipe and go from there. Most times, we would rather stick with this version than add a lot of other ingredients, like leeks, onions, and whatnot.
Simple really is best most of the time, isn’t it?
How to Make The Best Potato Soup Recipe
To make Grandmother’s easy potato soup recipe, you’ll only need a few ingredients and to follow a few steps.
Ingredients
Be sure to see the recipe card below for the full listing of ingredients, instructions, notes, and estimated nutritional information.
- Potatoes – I prefer to use russets. You’ll need 2 pounds, about six medium. You can also use Yukon gold potatoes.
- Water – You will need enough fresh, clean water to cover the potatoes.
- Milk – I use whole milk in my potato soup. You can also use your favorite dairy-free milk substitute.
- Butter – the butter adds so much flavor to this soup.
- Salt and Pepper – add salt and pepper to taste for seasoning.
Step-by-Step Instructions
- Prep potatoes. begin by scrubbing your potatoes clean, peeling, and then cutting them into about 2-inch chunks. Place the potatoes into a large soup pot (I use my Dutch oven), cover it with clean water, and stir.
- Cook. Cook over medium heat until the potatoes are fork-tender, about 20 minutes. Remove from the heat and drain away the water from the potatoes. Add your whole milk and butter to the potatoes and place back on medium heat. Allow the milk to bubble slightly around the edges of the soup pot, about 5 to 10 minutes.
- Season. Remove from the heat and season with salt and pepper to taste.
Creamy Potato Soup Recipe Without Adding Flour
To customize the consistency and texture of this soup recipe, you can serve it as shown with tender chunks of potatoes or you can make a smooth and creamy soup by using an immersion blender in your soup pot until it reaches the consistency you prefer. No need to add flour or make a slurry with this simple trick! Naturally gluten-free! But really, the chunkiness is simply perfect and I definitely recommend that you give it a try!
If you like a smoother textured soup with all the trimmings (think sour cream, cheddar cheese, bacon, and green onions), you may want to check out my creamy Loaded Potato Soup Recipe as well.
Dairy-Free Potato Soup
To make this soup dairy-free, replace the milk and butter called for in the recipe with dairy-free substitutes. A delicious option for dairy-free milk for this soup is coconut milk. I prefer to use the canned version for the added creamy texture. For the butter, there is plant-based butter readily available. Use your favorites!
Can You Make Potato Soup Ahead?
Allow your soup to cool completely and then store it in an airtight container in the refrigerator for up to 3 days. Reheat and serve.
How to Make Potato Soup Recipe in the Instant Pot
This easy soup recipe is so easy to make in the Instant Pot.
- Rather than cooking in the Dutch oven, add the water, potatoes, butter, salt, and pepper to the Instant Pot. Place the lid onto the Instant Pot and turn the vent to seal it. Cook on the manual setting at high pressure for 10 minutes, then use the quick-release feature.
- Remove the lid to the Instant Pot and set the cook setting to saute. Stir in the milk and cook, stirring often, until thickened, about 3 minutes. Turn off the Instant Pot and serve. If you prefer a smooth and loaded potato soup, use an immersion blender to blend the soup and serve it with your favorite toppings.

I would like to know of I can freeze it
I haven’t frozen this soup, Sheila, but you should be able to. Allow the soup to cool thoroughly. Place into freezer safe containers, leaving at least 1 inch headspace. Freeze up to 6 months.
This is exactly how I grew up eating this soup and my mom and grandma still make it for me when I’m feeling bad. I love this simple version way more than the “fancy” versions.
Jennifer, your mother and grandmother sound like mine. They always knew I wanted this soup when I didn’t feel well, too.
Excellent!
This is almost my families except add a onion in with the potatoes and we always eat it over saltines. Iโve made it with 1% and still itโs delicious I do keep some of the water too and add a stick of butter itโs is soooo good, itโs always our halloween meal.
Thanks, Sarah. I think it is amazing that so many people make this soup just like my Grandmother made or with slight variations.
My mother made it this way. When I got married and started cooking, I made potato soup loaded down. It was really yummy..but the other day I saw this and decided to make it.. It turned out delicious..something to be said about”less is more”
PS I add a couple slices pepper jack cheese that thickened it up but I didn’t really taste like cheese much thanks for the recipe
Did this as a project with my toddler this week! He helped me wash the potatoes and pour the milk! Thank you for such a simple & yummy recipe! Really hard to find these days! Definitely will become a staple for us!
Savi, I always loved to cook with my son, especially when he was little. They are some of the sweetest memories. My grandmother would have been thrilled that others, like you, are making her recipe with their children.
Sounds good Iโll try it
I hope you enjoy the soup, Linda.
My father and paternal grandmother made it often. Dad would serve diced chives or onions on side. Perfection!
Followed recipe and it was ok but wanted thicker so i blended it. Also added some chicken bouillon, tossed in a little shredded cheese and some frozen corn. Liked it even better the second bowlful with the additions.
You can always add other ingredients to this soup if you like. I always liked it as the simple soup my Grandmother always made.
You can mash half the potatoes to thicken it up I also added some caramelized onions ,sautรฉed mushrooms, fresh chives
This is just like what my mom made when I was a girl. So great to remember back, I’ll definitely make this for my family, thanks!
Thanks, Melissa. I always think of my grandmother with such sweet memories every time I make this soup.
I have been making this version for years. I do use a hefty amount of black pepper in it. Everyone that I make it for loves it. Also try making white cornbread and serve it with it. Delicious.
